Hi Les

Publish and be damned (please!).

For a few months I've been a lurking spectator who has contributed
nothing to the fractal world (yet?) but I enjoy and admire your work greatly.
I find PFE makes tidying up your posts easy and recommend it to anyone
having trouble with extra characters etc. (are you listening Angela?).
I can't claim to have discovered PFE - I think it was Jay who mentioned
it some weeks (months?) ago and I now use it for all my editing, saving
etc. of pars and frms from the list.

The fireworks are going off outside (UK) - perhaps I should get  a life!

Happy New Year to all of you who have introduced (seduced?) me into
your fascinating world of fractals.

John Evans

Merry New Year to all.

Thank you to Damien M. Jones for a quick answer to a nagging question.

Thank you to Janet Preslar for the flattering request.  No I do not
have a web site, but I'm working on it (so many porcupines - so little
time!) Sample pars should arrive in your e-mail later today.

Angela aka wizzle;  I can't give you a better understanding of math
but I do suggest that you read Bradley Beacham's formula tutorial - it
realy helped me get a beginning grip on some of what is going on in
the formulas tho Sylvis Gallet's stuff still sails by at an altitude
much greater than my height. (first you crawl, then you walk, then you
run :-)).  A zipped copy is included in Fractint ver 19.6 and there is
a hyper-text copy at the spanky web site.  <<hugs>> to you too.

When I save a file in windows notepad, with the frm extension, it looks OK
from file manager, but inside winfract it is read as a txt extension, and
subsequently does not appear to be read by the programme as a formula file.
Anyone else with this problem, or any suggestions.
I have spent the last two days of the new year holiday trying to do my
first fractal from a par file from the mail list, and not there yet, but
still trying

Beth  - set notepad's "files of type" to "all files(*.*)"  and you should be
able to save
your files with no further trouble ( though you will have to reset the "all
files" setting
each time you open notepad since it defaults to "text files".  If I find a way
around that, I'll let you know

Subject: (fractint) Fractint pausing problem
Date: 01 Jan 1998 11:22:11 -0500 (EST)

I am running Fractint on a pentium with plenty of ram. It's running fine in
both DOS and as a window, except for one problem. It pauses for a full
second between screen switches, all the text menus and the image. During
the pause the screen is black. The monitor makes a click that sounds like
a relay switch at this time. This happens independent of any textsafe=
options, and is independent of video mode. The graphics card is an nVidia
4MG AGP graphics card. I'm told by someone with a PII 266 from a different
company that they have this same problem and just got used to it, but I
find it maddening that my 486 is much faster. Does anyone have a clue
about this? Thanks!--Alice

Beth....

Use "file .....save as" instead of save....then enter the filename with the
frm or par extention.  That was happening to me too and is an annoyance.
You can re name the fileneme with the .txt (looks like formula.frm.txt)
portion of the name in windows explorer (the magnifying glass thingy) but
that is ..... I agree...a pain. Warning....do NOT use file manager in
win95....it has some nasty peculiarities...use explorer instead. In
explorer you will see the garbaged up name and can make the changes easily.

Les....

Your pars are too good not to be posted....what about trying a different
provider???  You can easily locate one in your area by shopping at

www.thelist.com

There is an option to find providers by entering your area code.  And any
decent provider will have you switched over within a matter of hours.  The
going rate is $20 per month, unlimited time with 5 megs of homepage space.

Alice,

I have exactly the same situation since I upgraded to my Pentium II with a 17"
SONY monitor and a Diamond Stealth video card with 4 mgs of VRAM.

I've spoken to SONY and Diamond Stealth.  I've been assured that the clicking
is not harmful and that the screen delay is normal in DOS programs.  I'm not
really convinced in either case, but I went through 2 other brands of 17"
monitors and they all did the same thing.

I can get rid of the clicking sound by changing the refresh rate for the
monitor from Optimal to Default which still works fine for Windows apps, but
then the pictures don't generate properly in Fractint.

Sorry, that's all I can offer.

Bill

I still can't open the phoenix formula that Paul Carlson so kindly

formula....but I keep getting error (5) undefined function (I think).

However....I have made progress.....if only in a sideways direction....I
also can't open 3d_balls from Jay.  Same error code. Maybe I need something
to add to Fractint to do if statements??? This seems the common denominator
for my problem. I downloaded and installed a fresh copy of Fractint hoping
that that would solve the prob.....

I know since I had at least 4 versions (working for those that sent them)
that the par and frm files have to be ok.  And I know that it is the frm
that is causing the error. sooooooo......I MUST be missing something in
Fractint....anyone have an idea what I might need????

Hi,
    Thanks for the interest youve shown

    I have now set the mail program to send plain text, so that should be
that problem sorted out.

    Yes you are absolutely right, the thumbs werent really thumbs at all,
but I now have thumbs prepared and am about to upload them, so they should
load much more quickly now.

    As far as the use of Pauls formula and par, the notes say no commercial
use without permission, my use is not commercial.  I think its a really good
image, however if paul objects I will remove it.

  C'est demande si gentiment!!!! :-)

  The formula for Moebius Star is available in my gallet_3.zip file.  Her=
e
it is:

Gallet-3-05 { ; Sylvie Gallet [101324,3444], 1996
 z =3D pixel , c =3D p1 , bailout =3D real(p3) :
 test =3D (flip(c*z) >=3D 0)
 a =3D (z-p2)*test , b =3D (z+flip(p2))*(1-test) , z =3D (a+b)*c
 (sqr(real(z)) < bailout) || (sqr(imag(z)) < bailout)
}

  And here is the formula for Firespiral:

Gallet-9-02 { ; Sylvie Gallet, [e-mail], Aug 1997
              ; Bailout: real part of p2 (must be > 0)
              ; Real and Imag parts of p1 must be > 0
              ; Imag part of p2 must be non-zero
              ; Use periodicity=3D0
   z1 =3D c =3D pixel , mz1 =3D cabs(fn2(z1)) , k =3D real(p1)*mz1
   bailout =3D real(p2) , z =3D imag(p1) :
   z1 =3D z1*z1 + c
   z1 =3D fn1(real(z1)) + flip(imag(z1)) , mz1 =3D cabs(z1)
   if (mz1 <=3D k)
      z1 =3D (z1 + 1) * p3 , mz1 =3D cabs(z1)
   endif

      z =3D z1^imag(p2)

  Tha latest par you posted has "reset=3D1950" which means you're using
Fractint 19.5.  Paul's formulas as all the formulas that use if..else

Subject: SECRETS of the par and frm  was Re: (fractint) Binary decomp...?*
Date: 01 Jan 1998 13:18:50 -0800

Hi Fractintiers,
Happy New Year.

I hop this Decomp algorithm is not too boring to anyone,
but I'd like to see this settled.  I post the same request
for help from the formula gurus who hold the SECRETS
of the par and frm ever so tightly. :-)

Here is a slightly changed version of the frm. I have
determined that a very large bailout is required. In fact,
a bailout of 4 screws up the usual decomp image produced
by Fractint (I complained of this before).

I have created a special web page to display what we
could be seeing if these frm ever work. There you will
find a program and images displaying the correct, IMHO,
decomp at level 2.  Here is the C++ version of the
algorithm:

int Maxiter=256;
int ColorPoint(Complex c){
// Decomp (c) by Jay Hill 1998
  int color=0;
  Complex z=0;
  for(int k=Maxiter; k>0; --k, z=z*z+c)
     if(norm(z)>1048576.)
       return real(z)>0?RED:LIGHTCYAN;
  return color;
}

I have experimented in C++ with decomp 256. If we get
this one working I can then make correct, IMHO, decomp
256 images. I could be wrong, but the symmetry in the
Fractint formula prevents its use in field line tracing.

http://home.san.rr.com/jayrhill/Decomp.html

Could Damien, Paul, Les, etc. (you know who you are)
please take a look at this?

Thanks.

Jay

Does any body know of a program that will assemble multiple gif files into
a single file.

I am having problems with simplgif.exe it has problems with some of the
multi part gif files
I am generating.

All the individual images are ok but the combined image sometimes fails to
generate properly.

Hi Les -- I've been following your trials and tribulations and wonder what it's
all about.  I don't think the problem is entirely at your end.  I get your pars
and run them with no editing and no problem.  I'm using Netscape's Communicator
4.04, copy directly into the Programmer's File Editor, separate the .frm's from
the .par's, and put 'em in appropriate Fractint subdirectories.  My ISP is an
East Coast USA outfit called Erols, but I can't tell you what mail software
they use.  I've had very little problem with anybody's .par's and .frm's,
especially since going to the PFE (thank's for the lead, Jay).

Actually, I only have vague recollections of a Top Ten
Reasons Why Fractal Enthusiasts Should Be Watched
Carefully, or something of the like.  It might have gone
something like this:

Top Ten Reasons Why Fractal Enthusiasts Should Watched
Carefully
by Jason Hine

10) The statement, 'I is my favorite number,' makes perfect
sense to them.
9) For some reason, they value mold, dust, flakes, and
dripping faucets.
8) To them, a great use for an expensive computer is to try
to model the above.
7) If it's broken, they won't fix it.  They like it that
way.
6) Have you heard the stuff they call music?!
5) They prize random formulas which produce graphs no one
understands.
4) One word: ZOOMERS
3) They believe in imaginary numbers.
2) Two words: ESCAPE TIME

... and the number one Reason Why Fractal Enthusiasts
Should Be Watched Carefully:

1) They spend years writing awesome software, then give it
away for free.

Hope you like 'em... :)  Jason

True, but if you have an external Zip drive, you can take it with you and attach
it to
(almost?) any computer... so I'd say just don't get an internal Zip drive!

Yes. I currently have a 17" NEC monitor mated w/"GTI" 'puter containing ~6
gig hd, 48MEGS RAM, #9GXE64 video card and have had no  problems
w/Fractint.  Other problems, though, but that is another story.

I would love to have an example of this - the PAR file and what
resolution in how many pieces gave you the problem. If the problems
are debugged then simplgif would do the trick.

I will send the PAR file next week
the interesting thing is I repeated the procedure 3 times and got basically
 the same error each time.

I was working with a 4 x 4 split-up of a gif file.
When I tried 3 x 3 it worked file and 5 x 5 worked fine but 4 x 4 refused
to work properly.

I had worked on 8 other 4 x 4 images that day all worked fine it was just
one particular
gif file that would not work.

  I think that the knowledge of math is not at all a prerequisite for
creating good fractals.  The orgfrm compilation has more than 7000 formul=

Alice,

 - Does anyone out there have a large new monitor that does NOT having this
 - problem of screen delay in DOS with clicking?--Alice

My experience with dozens of PCs, using small and medium-size monitors (17"
is medium :), is that newer monitors generally have about a one-second
blackout while switching modes.  I've not seen a new monitor that did not
have this feature.

Ordinarily, this isn't a problem, because most software doesn't change
modes often.  Only DOS programs like FractInt that require you to
frequently switch between text and video modes.  If FractInt's text
displays could be overlaid on its graphics screen, it would save a lot of
wear and tear on monitors; I have killed a monitor twice by rapid switching
of modes in FractInt.  (It was not FractInt's fault, just that that's the
only app I've got where I can get switching modes two or three times per
second!)

Subject: (fractint) Re: decomp FRM
Date: 01 Jan 1998 19:20:58 -0600

Jay,

 - I have created a special web page to display what we
 - could be seeing if these frm ever work. There you will
 - find a program and images displaying the correct, IMHO,
 - decomp at level 2.

I'm not sure the image on your web page is entirely correct, but with the
suggestion Sylvie provided, I get an image very similar.  I too have
noticed that you need to subtract 8 or so from z when using outside=real in
order to get the color you expect.  I do not know why this is so, but it's
possible this was a fudge factor introduced in FractInt to make
outside=real to produce aesthetically pleasing results when used with
normal fractals. :)

My goal in working with decomposition has been to *absolutely* retrieve the
field line of an escaped point.  Your FRM provides only the least
significant bit.  _Chaos and Fractals_ indicates that successive bits of
the field line approximation can be read off by simply continuing to
iterate; when I try that, though, I run into some problems.

My first problem is that I *do not want* the values retrieved to be
discontinuous at integer dwell boundaries.  I want something that is
totally smooth and consistent, regardless of the number of iterations
performed.  The FRM you have posted doubles the frequency of apparent field
lines with every extra iteration.  This is no good for me.

_Chaos and Fractals_ indicates that the first iteration provides the most
significant bit of the field line, based on the sign of the imaginary
component.  As long as I don't actually add in bits derived from iterates
with magnitudes less than 1048576, this works fine for me--I get accurate
results.  But I *need* those higher significance bits.  For example,
consider this modification of your formula:

J-decomp1 { ; Binary decomp (c) Jay Hill 1997
            ; modified by dmj 1998
            ; use outside=real
  done = 1, iter = 0     ; Iteration flag.
  weight = 1, w = 0, b = 2^4096
  dummy=maxit            ; forces float=yes
  z = 0, c = pixel:      ; Mandelbrot initialization.
  z = sqr(z) + c         ; Mandelbrot calculation.
  m = |z|
  weight = weight * 0.5
  IF (m >= 1048576)      ; Point exceeds threshold.
    IF (imag(z) > 0)
      w = w + weight     ; Color 2 on the other
    ENDIF
    IF (m >= b)          ; Point exceeds bailout.
      z = w*1024 - iter - 8 ; fixed color scale
      done = -1
    ENDIF
  ENDIF
  iter = iter + 1
  done >= 0              ; Continue if the flag >=0.
}

Here I keep a running weight, which indicates the decreasingly significant
"bit" that each iterate provides of the field line.  These are accumulated
to w or not, based on the sign of the imaginary component.  Note that
because bits are not "counted" until the magnitude (m) of z exceeds 2^20,
points closest to the M-set have their most significant bits forced to
zero.  For close-in work, where I want the colors to repeat quickly (and
the more significant bits are effectively lost anyway) this might not be a
problem, but in practice it still seems to be causing problems.  For fun,
try changing the 1048576 to 0 and use a full 256-color palette.  Points far
from the M-set (where the iterates reach high magnitudes quickly) show
smooth gradations of color, indicating appropriate field line
approximation.  Up close, though, things get twisted and gnarled; the bit
test is yielding inaccurate results.

Do you know of any way to extract the appropriate bit of the field line
from iterates of low magnitude?  As I indicated in my previous post, if I
do this on a Julia set, it works *flawlessly* as long as imag(c) = 0.  The
farther imag(c) is from zero, the more messed-up it gets.  This affects the
M-set, of course, because each point is pulled from a Julia.

The 15" ViewSonic that I use _does_ have the relay clicking but it has not
been a problem (it's also slightly less than a second). In fact, the only
monitor that has ever given me grief was the only one that _didn't_ have it.

As far as Fractint _pausing_ during mode switches; are you sure that it
does? I frequently find that once the monitor has finished switching modes,
Fractint has already been drawing as if there had been no delay at all.
With a "g1" preview, for example, the image is sometimes completed (with
sound effects and all) before the monitor has finished switching.

The only delays regarding mode switching that I have experienced are the
occasional pauses in refreshing the image as a result of the
"textsafe=save" option. I may have to wait a second as the image is painted
back on the screen using the default colour map and then reloading the
palette. If the pause you're experiencing is genuine, could this be its
origin?

texsafe=save causes the entire graphics screen to be saved and
restored to a text file. This could result in a pause at high
resolutions when switching between graphics and text modes.

My monitor pauses significantly during video switches without any
help from Fractint. By the time the monitor is through blinking, the
default 320x200 mandelbrot is done <g!>

Subject: (fractint) Re Field lines, monitors and CompuServe mess...
Date: 01 Jan 1998 20:36:16 -0800

Hi guys,

I am coming up out of DOS to see the email. I've been
making field lines. More on that later Damien. My web page
shows the BINARY decomposition. I agree getting the
exact line needs more bits.  All bits, IMHO, can be gotten
in one simple equation involving log(z).

About the monitor delay. I have a new NEC MultiSync XV 17+
and only get delays at modes above 1024x768.

Sorry for the off-topic here but I'm using MS Internet explorer
email reader on an cable modem (very fast) and I have not
seen the mess-up you all are referring to.  I assume that if
it is real, the remainder of this post should show it. Does
any one see anything wrong with this post? I leave Les' here
for you to see. It came in fine. So I conclude it is not
CompuServe!  Or did MS finally get it right, it can read
garbage?

Jay

Is that hostname for real? If not, people're gonna have a hard time giving
feedback about the PAR!

(BTW it is 11:38. If this thing bounces but goes through at 12:01, we'll
know for sure about the list having some kind of offpeak time restriction.)

Thanks for the formula.

Anyone else notice how a lot of very weird (and very LONG) formulas with
strange new abilities are coming out now that 19.6 has the If-Then clause?

Les, here is another report on your pars.  I received all of them completely
without "spurious garbage."  However, in all of them some lines, and in Happy
New Year! all lines were double spaced. I certainly don't mind editing your
pars, however. I generated all of them. Great images!  HNY!, both the image and
the formula, are amazing!  Gedeon.

I apologise for the HTML, I just assume that everyone can read it, I have no

Again I apologise for the mixup.  As for newbie, im fairly new to fractals,

Stephen....

Your original email came thru to me looking like an email....but I have
gotten some that looked like html code now and again.....I always wondered
what was happening and now I have a glimmer ........what email program do
you use that makes code like that??

Didn't you ask about pointers for color maps???  I think I forgot to
answer.....the way I got started was by reading Linda Allison's
lessons.....they are posted at my website.  My first color maps were really
pathetic so I used hers for a while until I could relate a map....and what
I wanted to achieve....with the fractal image.  But I'm still
learning....and I usually spend time looking at the color maps that are
generated by folks here.....I've gotten lots of great ideas....especially
from Paul Carlson.

Not even attempted yet. ProtoMatter hasn't reached that stage. The first

*ahem* Wrong or confusing? Since when am I confusing? :-)
You seem to be thinking of binary decomp. I'm thinking of the process of
decomp, binary, then 4-fold, up to Fractint's limit of 256-fold, carried
to the limit.

Yeah, spammers can't harvest lists and we Fractint Men could stand to meet

with gynecological fractals, as we could have fun with the real thing. :-)
(Too bad I live in Ottawa, and none of the intelligent young women on this

expect to encounter anyone else from this little shithole of a city
anyways, except Mike, who a) is not female and b) heard about this list from
me--or was it the other way around?)


Typo huh? Get a halfway decent mail program, then you don't have to type

Did you get a new monitor? Some monitors are faster and quieter at syncing
different modes than others. (Modes with different numbers of pixels down,
require the monitor sync to change. Text is usually displayed at 640x480.
You may be fractalling at 1024x768 or something. So the scanlines changes
and the monitor changes frequency every time you switch modes.)


Note: ProtoMatter will remain in graphics mode throughout execution, so
this problem won't exist with it.


Have you tried using the old monitor with the new machine?

Date: 02 Jan 1998 05:32:49 -0500 (EST)

>Is it a geometry thing? Or Trig? *sigh*

No, no, it's not geometry or trig... it's far, far, worse.

It's calculus.


<listens to various modems hanging up and NO CARRIERs popping on people's
terminals, one heart attack, two burst cerebral aneurysms, and five
nervous breakdowns>

Okay, those of you still listening: The best formulas for iteration have
multiple critical points; places where the deriuvative (consult your
entry-level calculus text) goes to zero. The rest have one, but never ever
ever zero.

Take the regular M-set formula. It is z^2+c. The derivative is 2z, which
is zero when z is zero (twice nothing's still nothing). Thus, it has one,
so there are fascinating julia sets more than likely (and indeed there
are) and an M-set. The Julia sets are obtained by fixing a value for 'c',
different for each Julia set, and varying z to get an image:

z=pixel, c=p1:
z=sqr(z)+c,
lastsqr<p2


The M-set is had by setting z=0, the critical point, and varying c:

z=0, c=pixel:
z=sqr(z)+c,
lastsqr<p2

Now look at the formula z^3-3*c*z+c. The derivative is 3z^2-3*c, or z^2=c,
or z=+/- sqrt(c). Thus there are two critical points. Each gives an M-set:

c=pixel, z=sqrt(c):
z=sqr(z)*z-3*c*z+c,
lastsqr<p2

c=pixel, z=-sqrt(c):
z=sqr(z)*z-3*c*z+c,
lastsqr<p2

And Julia sets like so:

c=p1, z=pixel:
z=sqr(z)*z-3*c*z+c,
lastsqr<p2


Also, to avoid a solid black screen, make sure the thing will tend to
infinity for some z!
Polynomials of at least 2nd degree work. Any Newton formula or twist upon
same will work. Any rational where the degree of the numerator exceeds
that of the denominator, or a term that increases with z is added to the
quotient, will work. Trig works because the sin and cos functions go to
infinity for large imaginary values, even though the familiar sine wave is
bounded. That bounded wave is only what goes on on the real axis and isn't
the whole picture.
Logs go to infinity, but too slowly. The derivative should exceed the unit
circle for z bigger than some bound. This means the modulus of f'(z)
should be greater than 1 for z with a modulus exceeding a certain bound.

Note that some formulas e.g. Newton don't adhere to these rules much! They
generate stuff because they still have many attractors. But since all are
finite, things are trickier. You must spot the finite attractors and make
an orbit trap aroun them:

PlainNewton {
  z=pixel:
  z2=sqr(z)
  z=z-(z*z2-1/(3*z2)),
  |z-1|>p2
}

This is the Newton iteration for z^3-1, with an orbit trap around 1. The
last line before the lone close brace is the orbit trap.

For a Newton fractal, an orbit trap of a different type works:

  z2=sqr(z)
  diff=(z*z2-1/(3*z2))
  z=z-diff,
  |diff|>p2

This catches all three attractors. Because the difference between the old
and new z is "diff", if diff gets close to 0 and stays there, z has hit a
point attractor. This thus traps orbits around all three attractors.

If you are unsure of the locations of attractors, or they vary based on c
or are too complicated to bother with (like two of the three in the Newton
iteration above), just trap for a z that stays put:

  oldzed=z
  z=...etc.etc.etc.
  |oldzed-z|>p2

(Note: All of these use p2 as a bailout. If p2 is left the default 0
expect blank looks from your computer! Literally. Instead set a small
value, like 0.001, and use float=y.)

By keeping older zeds:

olderzed=oldzed
oldzed=z
...
|z-olderzed|>p2

you can trap for both fixed point and 2-cycle attractors, whilst making
false alarms with 2-cycles less likely.

Note that for orbit traps around finite attractors, often periodicity=0 is
needed to get a picture at all, or else to get rid of bogus black squares.

You can trap for longer cycles without doing any work at all by
capitalizing on Fractint's periodicity checking. This time leave
periodicity ON! All you have to do is have no orbit traps at all (except
maybe at infinity), count iterations (iter=0, ..., iter=iter+1,...), and
then on termination have your thing set z to iter on the last iteration,
or 0 if iter==maxiter. Generate using outside=iter, inside=zmag, and
you'll get any infintie basin colored by iteration, any finite basins
colored by iteration, and points that never were trapped by periodicity
cheking colored color zero.


When you're making formulas, calculus is your friend.

It was on-topic I swear!
It may have been about fractal formulas in general but it had examples as
Fractint formulas. z=pixel, c=p1 and so forth.

Sorry, Paul, but IMHO 25 posts in 8 hours, most of them useless, is SPAM.
As for your calculus explanation I doubt whether anybody with less than a

1.  How big can a file of formulas be?

2.  If I change the location of the formula from
say....formulafile=fractint.frm ....to web1.frm and change the par
accordingly, will this work?  I would like to keep all the formulas I get
here together and still make the pars work. I assume I put my formula file
where fractint.exe is, right?

3.  Is there a limitation on the size of par files?

Date: 02 Jan 1998 16:26:23 -0000

Hi,
    Having spent some time playing with the 3DBalls frm by Paul Carson, a
thought struck me.  How easy is it to adapt this formula for other types?
Could you use it for a Julia? Could you use it for the INSIDE of a Mandel?
could you use it to spice up relatively "monochrome" types, are the
possibilities really endless?
    If I could understand how the damn formula works I'd have a go myself,
but I cant work out how the hell it works (anyone like to throw me a
tutorial?), so if someone with more skill than me could have a go........

Subject: (fractint) BEJ Formulas
Date: 02 Jan 1998 09:33:07 -0800

I downloaded a bunch of pars from the Spanky site ....among them Brian
Jones'.  I would very much like to see them, but I am missing the following
referenced formula files.

formulafile=bjbcmod3.frm
formulafile=bj2.frm
formulafile=builtn01.frm
formulafile=bjsg-g-1.frm
formulafile=msg-1.frm
formulafile=bjbcmod4.frm
formulafile=bej.frm
formulafile=bejmod~1.frm
formulafile=bjbcmod2.frm

I noticed that Sylvie very sensibly made Gallet.frm (which was avaialbe at
Spanky) as the single point of reference for her par file.

Which leads me to a suggestion....could we have some sort of naming
convention for the pars and formulas posted here???  So everything could go
into a single file .......say 98list1.frm, 98list2.frm......etc.  Not only
would this help organize...but also save hard disk space since even a 1k
file actually takes up something like 40k of disk space (at least in win95).

Thanks for your help.....

Paul,

 - Anyone else notice how a lot of very weird (and very LONG) formulas with
 - strange new abilities are coming out now that 19.6 has the If-Then clause?

With IF-THEN, formula-writing becomes more like programming.  I think just
about everything that you could do with IF-THEN, you could do before with
expressions multiplying a Boolean expression (x < 0) by some other
factor--but using IF-THEN makes a faster formula.

One reason formulae are getting longer is because people are commenting
them more. :)

Wizzle asked:

> 1.  How big can a file of formulas be?

All the different kinds of files that have entries (formulas, PAR,
lsystems, and IFS) are limited to 2000 entries. This only applies to
the user interface that displays the entries in a scrollable list. I
believe that it doesn't apply when Fractint is used in batch mode.
However, IMHO, the 2000 limit is way big enough, and users are well
advised to partition their collections. George Martin has written a
great program called Orgform that helps manage your formulas. I
recommend it.

You can specify a directory as well as a default file in the
formulafile= line. Fractint will try very hard to find a formula, and
will look in every formula file in that directory. If none is
specified, the current directory is used (not necessarily the
directory where fractint is.

Fractint's ability to search for formulas is a mixzed blessing. It
CAN mean that Fractint will find the wrong formula with (accidently)
the same name. Hence the importance of George's program. From time to
time we have big discussions about what Fractint should do, but so
far we haven't figured out something better.

> 3.  Is there a limitation on the size of par files?

2000 entries. There's also a limitationon the size of each individual
PAR and formula entry. We had to bump up the limit to accomodate
Sylvie Gallet, who writes formulas that spell out words <g!>

Mail software interacts with messages both at composition time and at
delivery time.  Some people have mail readers that can handle
printed-quotable and they do the decoding.  So it displays fine in
such mail software.  However, not everyone has mail software that
understands the printed-quotable encoding.  To that software, every =
appears as =3D, which for fractint par and frm files is quite
annoying.  The reason it is suggested turning it off is to accomodate
those people who don't have mailers understanding printed-quotable.
Also, if the mail message is viewed as a plain text file, the =3D's
will be everywhere.  In the case of fractint par and frm files, there
really isn't any reason to use printed-quotable, because we don't
typically use 8-bit characters such as european accented characters in
par and frm files.

Subject: Re: (fractint) Formula Questions
Date: 02 Jan 1998 11:47:35 -0600

Angela,

 - 1.  How big can a file of formulas be?

I'm not sure what the upper limit is, but I've got one that's 178K and
FractInt handles it fine.

 - 2.  If I change the location of the formula from
 - say....formulafile=fractint.frm ....to web1.frm and change the par
 - accordingly, will this work?

Yes.  FractInt looks first in the file specified by formulafile=, but if it
can't find the formula there, it will look through ALL the FRM files it has
for the formula.  So even if you forget to change the formulafile=, it will
still work.

 - I assume I put my formula file where fractint.exe is, right?

Put the FRM file with all the other FRM files.  If that's the directory
where FRACTINT.EXE is, then that's where it goes. :)

 - 3.  Is there a limitation on the size of par files?

Don't know about that either, the biggest in my PAR directory is 100K.
That seems to work fine.

Subject: Re: (fractint) 3DBalls question
Date: 02 Jan 1998 13:31:52 -0600

Stephen.

 - Having spent some time playing with the 3DBalls frm by Paul Carson, a
 - thought struck me.  How easy is it to adapt this formula for other types?

Somewhere in the formula will be a short section which is the real fractal
calculation.  The rest is the coloring stuff.  Change the guts, and you've
got the coloring technique applied to a different fractal.  As
well-commented as Paul Carlson's formula was, I don't think you'll have any
trouble.

 - Could you use it for a Julia?

Yes, but keep in mind that you need a parameter for Julia sets (unless you
embed it in the formula).  Most of my coloring formulae use all three
parameters, leaving no room for Julia exploration. :(

 - Could you use it for the INSIDE of a Mandel?

For any type which stops iterating early, coloring the inside the same way
as the outside is automatic.  But if you're using a coloring technique
which allows iteration to proceed normally, you have to keep track of the
number of iterations and stop one iteration before maxit if you want to be
able to specify a color for inside pixels.  You also end up having to turn
periodicity off, so that FractInt itself doesn't bail out early on those
interior points.  Basically, you have to fool FractInt into thinking all
the inside pixels are outside pixels.  See any of the -I variants in my FRM
file:

    http://www.geocities.com/~fractalus/misc/dmj-pub.zip

 - could you use it to spice up relatively "monochrome" types, are the
 - possibilities really endless?

Yes, the possibilities really ARE endless!  I have 100+ variants, plus
another batch I'm working on which aren't ready for "release" yet--one of
which I posted earlier.

 - If I could understand how the damn formula works I'd have a go myself,
 - but I cant work out how the hell it works (anyone like to throw me a
 - tutorial?), so if someone with more skill than me could have a go...

OK, a basic formula in FractInt works like this:

MyFormula {
  <initialization stuff> :
  <per-iteration calculation>
  <keep-iterating test>
}

The <initialization stuff> is where you put everything that needs to only
be done once per pixel.  For example, a Mandelbrot version would include z
= 0, c = pixel and nothing else.

The <per-iteration calculation> is where you put everything that must be
done for each iteration.  Our Mandelbrot example would just be z = sqr(z) + c.

The <keep-iterating test> part is the very last statement in the formula.
If it evaluates to anything other than zero, the formula keeps iterating;
the point hasn't bailed out.  A Mandelbrot would use something like |z| <
4, which has the value 1 ("true") when |z| is less than 4, and value 0
("false") otherwise.

Now, how you turn this into a "coloring" formula is a little trickier. :)
The basic trick is that FractInt provides several coloring modes which use
not just the iteration value where a point bailed out, but also the final
iteration value.  For example, with outside=real, the outside color is
defined not just by the iteration, but by iter + real(z) + 8.  (The 8 is
the fudge factor mentioned in other posts.)  Now, if we write the formula
so it watches for when z bails out, and stuffs in a phony real(z), we can
completely control the color FractInt uses to plot any given point.

Here's a simple example.  This is a stripped-down version of
dmj-Mand-Pnt-Dst from my FRM file:

dmj-Mand-Bof60 { ; outside = real: bof60 coloring, but outside

  closest = 1e+38                  ; Closest approach so far.
  done = 0                         ; Iteration counter.

  z = 0, c = pixel:                ; Mandelbrot initialization.
  z = sqr(z) + c                   ; Mandelbrot calculation.

  done = done + 1                  ; Done one more iteration.
  d = |z|                          ; Compute distance to p1 (squared).
  IF (d < closest)                 ; Closer than previous value.
    closest = d                    ; Save the closest approach.
  ENDIF
  IF (d > 128)                     ; Point exceeds bailout.
    z = sqrt(closest) * 75         ; Apply color scale.
    z = z - done - 8               ; Return value.
    done = -1                      ; Set flag to force an exit.
  ENDIF

  done >= 0                        ; Continue if the flag is clear.
}

The basic idea behind the coloring algorithm bof60 is to determine the
closest distance the point gets to the origin.  So in the first block,
where variables used by the coloring algorithm are set up, the "closest"
distance so far is set to a huge number.  "done" is used to count iterations.

The next block is the actual fractal calculation.  The initialization stage
is completed in standard Mandelbrot fashion, and the actual iteration code
follows immediately--again, standard Mandelbrot iteration.  This formula
uses the Mandelbrot set!

In the next block, the iteration counter is updated.  Then, the distance
for the currently iterated point is computed (|z|).  If this distance is
closer than the previous closest distance, the new closer distance is saved.

The last IF is actually our bailout test.  If z is too big (remember, d is
the distance of z from the origin) then we need to bail out.  The first
thing that is done is to compute a new value for z--we are stuffing the
color value we want in here.  sqrt(closest) is what we are basing our color
on, and the 75 is an arbitrary scaling factor.  The next line takes out the
other values FractInt uses with outside=real; we don't want those items, so
the formula subtracts them and FractInt adds them, and they cancel out.
The last line in the IF sets "done" to -1, which the very last of the
formula uses to tell whether or not to bail out.

Hope this helps get your started!

Textsafe=yes seems to be the best option. It's still a disappointment that

I improved that textured mandel image by improving the texture
lookup quality and anti-aliasing it.  The PNG file went on a diet as a
result and dropped 75K in size.  At first it seemed a little strange
that the PNG file would decrease in size with anti-aliasing, but when
I think of the details of how PNG stores the picture data, it makes
sense.  At any rate, I think the image improved quite a bit as a
result. :)

Jack...

I was mentioning the other day to someone starting a homepage that your
page is an example of truly fine web style.....as well as containing
magnificent images. You have very crisp layout....good
navigation....attention to bandwidth....all the essentials....it's really a
page worth studying for how well it's put together.  No need to
blush......but r40, b20 and g05 does produce a nice (frac) tint for blushing.

If you are using Netscape 4.0, that may be the problem. Apparently Netscape
4.0 doesn't like the Javascript there that plays the fractal music -- even
though all of the functions used are from Netscape's own Javascript site. It
seems to work with everything else, including Netscape 2.x, 3.x, Internet
Explorer 3.x and 4.x. I guess I need to change the Javascript. Will let you
know when its ready. You might like the image called "Fertility"

Maybe the following will assist in your search:

______________________________________________________________________
G. Keith Still BSC is a graduate in Physical Sciences from RGIT
(Aberdeen).  In the 1980's he was involved in the design of computer
systems for electron microscope imaging and chemical analysis.  He
developed computer systems for environmental data capture and analysis -
Compliance Manger - and linked them into virtual reality for
visualisation of data in four dimensions (including time).  That work
led to the development of the VEgAS (Virtual Egress Analysis and
Simulation) system - modelling egress from burning buildings.  This
system has been reviewed internationally, with Keith appearing on
various television programmes worldwide, and producing articles for
national and international magazines and journals.  Keith has lectured
at many organisations, including the Fire Research Station and the Fire
Services College, Morton-on-the-Marsh.  VEgAS was the runner up in the
innovation of the year award in 1992.

Keith sold VEgAS to an international fire and ventilation company.  He
then went on to created FMIG Limited and developed a more powerful
system LEGION that uses the Orchid fractals, a discovery he made while
recuperating from an operation on his back.  LEGION uses "entity
oriented programming" and handles 250,000 individuals.

Orchid Fractals have applications for currency market analysis, data
compression, data encryption, data analysis, digital fingerprinting and
crowd dynamics analysis.  LEGION has received international coverage on
European Business News and a variety of science magazines including the
New Scientist and Reuters.

Keith is currently registered at Warwick University (under Professor Ian
Stewart) for a PhD in Mathematics.

What do three parameter fractals look like?
The three interdependent functions are expressed as objective, motility
and constraint.  This applies to a wide range of interactive systems
from crowd dynamics to ecosystems modelling (Objective can also  be
expressed as a function of some environmental change). Using phase space
diagrams to illustrate these as two dimensional objects, to Keith's
delight, they produce rich, beautiful and very complex shapes.

The author named these Orchid fractals (the internal shapes reminded him
of an Orchid).  They map the interactions within this type of dynamic
systems.  It would require a trained mathematician to use the
relationship between geometry and dynamic systems within the Orchid
phase space diagrams and to non-scientists they are just pretty shapes.

However, Keith's entity oriented programming technique's use these
fractals to map these interactions inside a virtual reality model that
is more understandable than a phase space diagram.

Some curious phenomena of Orchid projections are that, when applied to
some mathematical functions (for example the stock market) they distill
out strange attractors.  They produces shapes, full of detail and
mini-bifurcations but self-organising as if there was a higher order,
limiting function holding them together.  Applications for these
algorithms include data compression, data encryption, currency market
analysis and digital fingerprinting techniques.  Keith is currently
developing a series of applications using the Orchid Fractals.

Aw, come on Paul. We were all newbies once and most of us are

helpful advice by private email than ridicule them publicly.

If I was shot down for all my mistakes I'd have died from

Thank you. Six months ago I thought HTML was a four letter word
I hadn't heard yet. Only a couple of months ago a number of
readers of this list gave me valuable advice in correcting
a browser width problem I had. If *I* can do this it means there
is hope for us all.

I'm just putting the finishing touches on a complete redesign
of our gallery pages. It is much slicker with a (I think...)
unique way of exploring the gallery. A few more images and
larger pics. The bandwidth will suffer a little but such
is the price of style. Sigh...

Thanks again. I'll tell Margaret :)

Date: 02 Jan 1998 20:27:12 -0800

I hope someone can help with this- I  have been reading
all the posts about saving par files and  I am
still having problems with some of them.  I would really
like to get 3D_balls by Paul Carlson - it sounds like it
is fun and I would like to get the images from the pars that
other people have made out of it.  Les St. Clair's don't seem
to work either.  ( The New Year message worked ok in the
attachment.)  Nearly all the other pars and formulas work now.
I am using Netscape 4.04 and Fractint 19.6, and I open them
into Pfe32 and save them as whatever.frm or .par. (into
 the same directory as Fractint without defining exactly where
it goes) and it sometimes it  seems to hunt for a formula but usually
finds it. ( I thought I was doing something wrong but so many of
them do work that I think this is probably not it- duuuhhhh!)
(Maybe it's my brain- ohhhhnooooooooooooooo)
Maybe it is the server or maybe it would work better in the
earlier version of Netscape.  Can someone re-post  (or send
to my address)  3D_balls  and I can see if it works better in an
earlier version of Netscape, or any other suggestions would be welcome.

Having looked at Damien Jone's formulas (and even having a go at removing
IF-THEN operators as he describes - oh yeah, it can be done, but who would
_want_ to?) I reckon one approach to shortening formulas (and formula
files) would be to introduce file inclusion. Then one wouldn't need to
repeat the same code multiple times one for each variant; just write it
once and insert references where it's used. Something like
"include(initlib.frm/variant1)" perhaps, which can be abbreviated to
"include(variant1)" if variant1 is to be found in the same .frm file as the
formula using it.

Just a thought: it would shorten dmj-pub a fair bit, and would make adding
new bailout/colouring formulas a lot easier, and would allow interested
readers to concentrate on the relevant parts of the code more quickly.

Feeback, anyone?
MLO.

I think it's a great idea. The only problem I foresee is that
right now people have trouble regenerating images from
pars because they are missing formulae and/or colour maps.
It might just aggravate things if they have to worry about
missing inclusions as well.

;For each of the two equations there are Julia slices parallel to three
;different planes, and a Mandelbrot. For the Mandelbrot set p3 to a bailout
;(400 works for me). For the Julia sets p1 is the Julia parameter, p2 moves
;the slice perpendicular to the slice plane, and p3 is the bailout with the

Hari Seldon??? :-)
Must be an Asimov fan. :-)

I dunno if this is the same fractal, but I saw a fractal calendar with a
picture titled Orchid on it, the picture was quite obviously Newton's
method to solve e^z-1=0.

That would be: z_new = z - (exp(z)-1)/exp(z)
or z_new = z-1+exp(-z).

Try putting an orbit trap around 1.

is the corresponding Julia set formula, but using a

Good point - and I wouldn't want to have to scrabble through and make sure
all the inclusions are good before posting a par. It's hard enough now just
keeping track of where the original formula and colour map is coming from.
Perhaps an option on the par saving screen for making a par file suitable
for pasting into a post - attaching a frm:-prefixed formula, doing all the
inclusions, explicitly writing the colour palette etc.

Post Scriptum:
I've just noticed something odd. I was being bounced a bit back there and
now I remember having changed the address I'm posting to from
"[e-mail]" to "[e-mail]" and it worked.
Maybe I should change back and see if I still get through.

Morgan,

 - (and even having a go at removing IF-THEN operators as he describes - oh
 - yeah, it can be done, but who would _want_ to?)

Only someone who has to get such a formula working on an old version of
FractInt... :)

 - I reckon one approach to shortening formulas (and formula files) would be
 - to introduce file inclusion. Then one wouldn't need to repeat the same
 - code multiple times one for each variant; just write it once and insert
 - references where it's used.

This is a *fantastic* idea.  As long as I could put included snippets in
the same FRM file, and FractInt had an option to automatically assemble all
the FRM pieces needed for a PAR, this would be *excellent*.  Yumyumyum.

What a positively splendid idea.

These are very spiffy images.  I'm always surprised at what other people do
with the formulae I made... just shows me what a rut I've gotten into!

I'm not sure you want to label me an "expert", though.  I just muddle
through the best I can!

Happy New Year everyone!

I have updated my web page with some new truecolor images, and for those of
you who would rather not hear fractal background music, there is a control on
the bottom of each page which allows you to turn it off. The Windows 3.1
version of Truemand uses the new exponential smoothing truecolor method for
anyone who would like to see how it looks.

Ron,

 - I have updated my web page with some new truecolor images...

These are very interesting pictures.  Some of them look like they use
various "orbit boost" techniques, particularly ones like Whirlpool.  Aside
from the smooth coloring :) how were they created?

 - The Windows 3.1 version of Truemand uses the new exponential smoothing
 - truecolor method for anyone who would like to see how it looks.

I put together a quick FractInt FRM to mess around with the technique--it
is most effective, even in 256 colors.  What's particularly impressive is
that it works for types like NovaM, where I've been trying in vain to apply
Linas Vepstas' algorithm.  How does the exponential color value relate to
the iteration value (or does it)?

Subject: (fractint) Field lines, binary and Trinary decomposition
Date: 03 Jan 1998 21:29:23 -0800

Hi Fractintiers,

In the last month there are at least two threads, maybe
three, on this topic mixing and folding, in the true spirit
of chaos and fractals.  References below are to posts
to this forum in the last few weeks.

I hope you enjoy the formulas and pars.

Jay

        Field Lines, Binary and Trinary Decomposition
    (c) Jay Hill 1998  (as if anyone would want to copy this...)

1) There is the question of how to plot binary decomposition.
One way is as posted, matching existing text books. That is
choosing black or white depending on whether the bailout z is
above the real line. Fine, but the alternative, left/right of the
imaginary axis just shifts the phase of the black-white blocks
and has the interesting effect of somehow correctly mapping
the real line. Indeed, the midgets and buds on the real line
have a numbering scheme based on this method. But as
mentioned, it breaks down for complex midgets and buds. For
these, a different boundary is needed. And it is not the imaginary
axis. It is at an angle depending upon which field line you are
following. Worse still, the boundary (for coloring black or white
based on z) is not always straight!

2) Another thread is the issue of extending binary decomposition
to more bits. I claimed earlier that the approach Paul Derbyshire
suggested will not work. One reason is the curved boundaries
mentioned in 1). In the early iterations, the real line boundary is
not a good substitute.  Paul is trying to estimate the external
angle corresponding to c in z<-z^2+c.  The best way to get the
external angle is iterate to bailout and measure the angle of z.
That is,  angle = imag(log(z)).  There is an ambiguity because of
the number of iterations used to get to bailout and the actual period
of the field line.  Yes, every field line has a period, namely, the
period of the component it leads to. This brings up a problem with
binary decomposition. The lines defined by binary decomposition
have no period. The lines (follow the radial boundaries of the
checker pattern) seem go to chaotic points. So, to extend binary
decomposition to 256 levels, follow z to bailout, set the color to
256*[imag(log(z))/(2*pi)].

3) A third thread is how do we follow field lines. That is two
problems, how to plot them and how to follow them for pan and
zoom. We can start with what we know from 1) and 2).  Now
we must choose a set of field lines to plot and they must
all have the same period (leading to components having the
same period). Otherwise we are back in the problems of binary
decomposition, namely colors scrambling at each iteration boundary
curve (the ones that go around the MSet - not radial).  So we can
choose the simplest interesting case, period 2.  There are two field
lines going out to 120 degrees and 240 degrees from the base of the
period two bud (-0.75).  The shape is like an hyperbola. So the
method is iterate and select color based on the three regions. One
wrinkle, we must do two iterations in each loop to keep the pattern
from scrambling.  So here is a frm and par to do just that and plot lines.

frm:J-decomp3 { ; Trinary decomp (c) Jay Hill 1997
                    ; One boundary leads to -.75
                    ; Another boundary leads to +i.
done = 1               ; Iteration flag.
iter = 0               ; Sylvie Gallet's suggestion
z = 0, c = pixel:      ; Mandelbrot initialization.
z = sqr(z) + c         ; Mandelbrot calculation.
z = sqr(z) + c         ; Mandelbrot calculation.
IF (|z| >= 100)        ; Point exceeds bailout.
  done = -1            ; Set flag to force an exit.
  y=.5*imag(log(z))/pi
  IF (y<0)
    y=y+1
  ENDIF
  w=3*y
  z=w - iter - 8       ; Sylvie Gallet's suggestion
ENDIF
iter = iter + 1        ; Sylvie Gallet's suggestion
done >= 0              ; Continue if the flag >=0.
}

The par files are at the end.   This can be extended to the next level
and so on......  I have chosen color banding so you can follow a few
of the lines all the way to the component base.

Jim....

I'm not sure what you want to know about color maps....but Linda Allison
has two excellent lessons on using and making them which I host at my web
site....

http://wizzle.simplenet.com/fractals/fractalintro.htm

These lessons are easy to understand and full of examples. I liked them so
much I asked Linda if I could host them so they would always be
available......also take a quick look at my Fractint hints which gives the
very basics of grabbing a color map from an existing image.

Angela aka wizzle

ps.   you are welcome to download any of my gifs and use my color maps

Wonderful page...no wonder it took you two years!!! My first effort was

to download with the images.....no wondering what goes with what.  I also

Angela,
They may be helpful if you want to make maps from scratch, so to speak,
without a particular fractal in mind.  In addition, Mapmaker can save (or
convert) map files in the csv format, which can then be graphed and
manipulated in interesting ways in Excel.

Humpf....

I do that anyway with Fractint based on what I learned from Linda.  I've
been able to figure out how to make maps that "do" things in a general way
(like carving out areas of black) then do very minor tweeking for
particular images.  What I like about Linda's explanations is she say HOW a
map enhances and image...not just the mechanics.

But the excel part sounds interesting.....and I know we all learn in
different ways....do you have examples of stuff before and after excel
manipulation?? I can only understand what I can see.....not technical
explanations.

The formula for WhirlPool is actually quite ordinary. Its the standard
Fractint mandel(fn||fn). Here is the equivalent Fractint par file. This will
generate the same image, but with the banding characteristic of Fractint:

WhirlPool          { ; .                                     t=  0:02:25.72

  zz0<7>99J<15>WWz<7>0J9<6>0bJ
  }

Some of the images do use a variant of the Pickover orbit trap method. The
variant allows coloring to give a more 3D effect, and a user variable to
determine how close to the x or y axis the orbit must be to be trapped. The
coloring is based upon both the iteration count and how close the orbit is
when it is trapped. I am thinking about incorporating some of Paul Carlson's
great methods, since it would be a simple add-on to my current code.

>> I put together a quick FractInt FRM to mess around with the technique--it
 is most effective, even in 256 colors.  What's particularly impressive is
 that it works for types like NovaM, where I've been trying in vain to apply
 Linas Vepstas' algorithm.  How does the exponential color value relate to
 the iteration value (or does it)?

  >>

As far as the relationship between the iteration count and exponential color
value, I have done some empirical exploring running the compiler in the debug
mode but have found no clear relationship. For low iteration counts the
iteration count may be 10 fold or so larger. As the iteration count increases
it looks like the exponential color value might converge towards the iteration
value. For some of the images on my page, the ratio is less than 1.5. This
might be an interesting area to explore mathematically. Note that for
WhirlPool the Fractint coloring based upon the iteration count and exponential
coloring are quite close. All I had to do was to rotate the palette a little
bit.

Thanks, everyone who is using Makemap. By the way, any fractint map, including
the ones created with Makemap, can be readily brought into Excel by using
space as the delimiter rather than comma (csv).

Special note to Angela: Makemap can create maps, both by the Fractint
approach, and it can also use four different algorithms to design a complete
map (sine, fourier, HSI and RGB). It runs under Windows 3.1 and 95. I haven't
checked it under NT.

Thanks for the explanation....let's see foyer transformation (has to do
with decorating the entry hall)....sines (poor thing can't spell sign or
foyer).....and 4 algorithms, eh??? (probably a new rock band).

It's truly wonderful how Fractint allows us artsy types to communicate so
well with you technical/math wizards and brings us together.

Am I right so far?
I still get an oops message, and can't parse that formula

Is there a way for the pars to load automatically, or does one always type

I may be doing this all wrong, but what I do seems to work fine for me. Due
to limitations of notepad I have .frms' defaulted to WP. In the above
formula, I suspect a little bit was missing: first line after   Bessel-2 I
added:  (after the "{"  ; Bessel2

It now works fine.

The .par, after inserting into .par file also worked fine. (got rid of the
">'s".

(>Is there a way for the pars to load automatically, or does one always type
>them in manually)

For what I am doing, still using windows, I highlight the entire thing, hit
ctrl-c, bring up where I am going to put the item, then hit ctrl-v. Saves a
lot of typing.

Beth, you save the whole thing, starting with the "Q" in QuartzM2C (which
is the name of the formula) and ending with the "}", which marks the end of
the formula.

Not sure I understand your question, but the way to change parameters while
a par image is drawing is to hit "z", which brings up the parameter screen.

Hey that's mine:)

Save the whole thing in a .frm file.

Save the above in quartz.frm and read in the par with the @ command.
It will find the formula and use it without difficulty.

Bud,

 - Do all formulae have to be expressed in terms of Z, or can I separately
 - process real and imaginary components?

It's best to use "z" because FractInt looks at z to check for periodicity.
If you don't use z anywhere in your formula, FractInt sees that z is in a
tight periodic loop (all zeroes) and bails out early.

If you want to calculate the real and imaginary values separately, you'll
just have to write the formula to run that way.  It's a little cumbersome,
but can be done.

What is it about the new year that we all feel compelled
to change things? Yep, our pages have changed too.

A few new images, but all are larger now. Mostly a new
non-linear way of viewing the pics. Highly organized
types may still view things in a systematic manner. But
now you can simply "wander" through the images. I hope
you do because different image sequences might produce
different experiences.

Take a look and tell me what you think. The old pages
still exist and are linked, but the gallery is now
essentially separated from them.

Speaking about links, if any of you would like me to
provide a link to your pages, let me know. Your pages
need only be fractal oriented and free of any
prurient or prejudicial content. Other than that,
we're an equal opportunity site :)

The old pages remain at:
http://www.globalserve.net/~jval

The gallery is now at:
http://www.globalserve.net/~jval/phractal.html

I've had a few people ask why they couldn't read other
peoples' comments. I decided to add a previous comments
page but am still not sure how I feel about this. If
I've quoted you and you'd rather I didn't, let me
know.

Oh, and I've slightly modified the old pages. If anyone
using a wide browser screen experiences problems, please
let me know.

Thanks for your time, people!

One more advanced point that will make it much easier for you to play around.
Change COS in your formual to the variable fn1.  When you call up the formula
using T as I explained in the other message, you will then be able to hit Z
and change fn1 to COS or SIN or TAN or anything else without leaving Fractint
and writing another formula.

Let me know if you have any more questions.

But I wanna know who is able to invent the SMALLEST .frm (the letters

After a few webpages, I cheated and just looked at the images from your

Didn't notice anything unusual in appearance, just a few minor text
related items (grammar and spelling).  Also, the "Top of Page" link on
the bottom of http://www.globalserve.net/~jval/isitart.htm was not
displaying (you had the color set as white on a white background).  A
couple of other little things, but the look and feel of the website is
nice!!

The thunbnail images were available from Jay's website to view for this
person, but the PARs never got included into the Contest Kit zip file.
One of those images got a single vote though.

That's probably why no further postings have been seen from that email

There is a brace missing from the last line of the par.

The next line is where you are telling Fractint to find the formula, =
first by filename, then by formulaname within the file.  So.... you =
should be storing your par as bessels.par

This is where you went wrong. I cut and pasted this into files as you =

It is called GSpecial.par.  You sure it is not there?

I just downloaded http://www.geocities.com/CapeCanaveral/Lab/3825/Contestk.zip
It is there.

The copy that I last downloaded only had 48 PARs.  The GSpecial.par was
not in my Contest.zip file.  Maybe that was the last one added and I
downloaded before the final update.

But I do remember seeing the images on the Contest webpage along with
the PAR link for the email posting.  Others probably had a full version,
due to the fact of a vote being counted.

Oh well, that was way last year, too much time has gone by (and too many
parties).

Hi guys and gals,

Sorry to be-labor this, yes GS was near the last to post
but not the last. GS posted this:

Message-ID: <[e-mail]>
Organization: Artist's Network

The dates I have on my machine for these files are, sorted by date

GSPECIAL.PAR      2426 12/05/97 22:55

So we have D M Jones (a repost but I don't think I saw the original),
7 minutes after GS and these: J Oliver (repost), K Mitchell (repost),
S Gallet (repost) after GS.

My ftp log shows this
97.12.06 00:13 B C:\jay\transfer\Contest\GSpecial.par --> home.san.rr.com
/Contest GSpecial.par

Finally, this file http://home.san.rr.com/jayrhill/Contest/CONTEST.ZIP
is dated 971206 08:21 according to ftp, and it contains the GS par file.

So, his material must have appeared about Dec 6.

BTW, I will make one more version of the Kit with image names
under the images.  That should make it nicer. Then it can rest
at Spanky at last.  So if there are any other remarks...please write.

Also, I would like to quote a few of the early postings by Nuke
and a few others which were the spark to start the contest.  Any
objections?

At your service,
Jay

Dick, you write about separating the pars and the frms, and putting them
into appropriate directories. Please can you answer my question?
I am new to Fractint, but really keen to try to create some fractals from
the frms and pars other than the standard ones available in fractint. I
havae so far copied frms into fractint itself, and pars into a subdirectory
of fractint, but I have no idea how to pull them together to create an
image. I can call up the frm file, and then get a screen asking for
parameters. I don't know what to put into what box, and I thought there was
some way of entering an entire par file into fractint, but so far I can't
work it out. ANy words of wisdom will be much appreciated.

Subject: (fractint) The dreaded aaaaaa's again :(
Date: 06 Jan 1998 08:15:45 -0000

Back in the "(fractint) text editor" there was various discussion on how to
rid text files of the dreaded accented 'a'.

One suggestion was to download PFE, Which I did...

Having copied par text from outlook, pasted it into PFE saves out as a *.par
file.... it still has the a's when read by fractint!


Am I missing something with PFE, could whoever suggested (don't have the
posting anymore) PFE help me out.

Thanks Peter

I looked at the time of my Contest.zip file, it was downloaded on
12/05/97 at 20:18:00 CST.  But, if you had to put in others besides the
GS posting, why does mine contain all but that one PAR???

I know I must have grabbed the zip file early by a few hours, that's the
only explanation.

Anyway, I was also looking back on how the contest got started and found
this posting that was 14 hours before Nuke's:

        I agree. Why not use the famous 'Tim's_random'

You don't mention it: did you do any editing (a global search-&-replace,
perhaps?)

If you already have it saved as a par file, just drag the file's icon to
the PFE icon on your desktop (it's not there? For shame!). Bang: instant
opening! I like this!

...........(snipped stuff)............

If you peruse the many personal fractal galleries on the web, two
things become immediately apparent. Some fractal artists consistently
produce beautiful images while others are erratic. (I am not
speaking here of the simple personal likes or dislikes of the
viewer.) Also, despite the rather impersonal origins of the fractal
formula, a number of these artists have also developed their own
style which becomes recognizable with repeated viewings. It is not
that you can immediately identify the creator of a particular image.
Instead it is that, upon discovering the artist's identity, you think
"Yeah- that looks like something she'd do..." This certainly suggests
that there is more involved than cold calculation.

An interesting experiment would be to post a mundane formula
and have the readers of this list plug it into Fractint, work with
it in their normal fashion and then post the results. I predict that
each will be different but that many will be very similar- a strong
family resmblance, if you will. However, I also expect that some
will look so radically different that it would be difficult to
believe they share the same formula. In other words, art may be
calculating but it need not be mere calculation.

Hi Beth,  I'm also new to Fractint (and new to this list :-) ), but do know
that Fractint can read any par file you copy into it:

From the main menu, click on "run saved command set <@>" under File (or just
press "@").  This will take you to a directory list of par files. Navigate to
the subdirectory containing your par file. Then select a given par entry in
that par file and Fractint will draw the fractal.

When you start by calling up a frm file, you must enter parameters.  This is a
matter of trial and error - experiment until you get an interesting looking
image.  Then you can save the parameter settings for this image as a par file
by pressing "b".

I hope this helps!,

Mark

Well... You can't edit or search and replace the a's if you can't see them!
The whole point is that they are not visible in email or when pasted into
PFE.
They *are* visible when read by FractInt..

Hi Everyone,

            I have been reading the fractint mailing list (in digest form)
for a couple of days now and am going to perhaps nievely considering the
other work I have seen post my own par and formula file. Fractint IMHO is
one of the best programs I have ever used and the authors deserve much
credit especially considering they get no financial reward. The formula
below was created via a combination of luck and educated (well only to year
12 maths) guessing:

Copy following par entry to a par file:

tattered           { ;Copyright Ben Leighton 1998

  }


Copy following formula to ben.frm:

c7manderiv  {
;Copyright Ben Leighton 1998
;try sin(fn1) and cos (fn2)
q=pixel, a=1, b=flip(1), last = 0:
a=a+ fn1(imag(pixel)*10*(1/imag(q)))
b=b+ fn2(real(pixel)*10*(1/real(q)))
q=(q-a-b)^2 + pixel
(a+b) <= 300
}



                                                                        :) Ben

Hi Beth - I believe you are mixing apples and oranges here, probably because
the word parameter gets a little overworked.  The parameters asked for in the
screen you get when you call up a formula refer to replacable values written
into the formula (some formulas have no replaceable parameters).  Put anything
in there.  Some things will work some will not. Those of us with limited math
skills just use trial and error here and save the results from the lucky
shots.

To enter a particular image's parameter file ( these are files where all the
above choices and more have already been made and the resulting image saved.)
you press the @(or 2) key whenever you have an image ( such as the mandelbrot)
on the screen.  This will present you with fractint's default fractint.par
collection of images.  Pressing F6 at this point will let choose from among
whatever other .par collections you have acquired.  You then open the desired
collection, select the desired image, and press "enter".

Another point that can lead to some confusion (I believe someone else may have
mentioned this) is that a .frm file may contain many individual .frm entries
and a .par file may contain many .par entries

I hope this helps.  Good Luck and many happy hours Fractaling.

Date: 06 Jan 1998 14:01:39 -0300 (BST)

Happy New Year to all!

Here in Britain we get a short series of science TV broadcasts every
Christmas - the Royal Institution Christmas Lectures, for young
people.  Last night, I just got round to watching my tape of the fourth
(out of five) of these, which was about Chaos.

The lecturer (yes, they are filmed as lectures in the RI Lecture
Theatre) was Prof Ian Stewart, and he mentioned Mandelbrot sets,
showed an animation of a Mandelbrot zoom, a Julia zoom and one other
similar that he didn't name.  He also talked about Barnsley, referred
to the Encarta IFS encoding, and tried to show how an IFS coding
system might work (not terribly well, I thought).

There was also a 'manual' demo followed by a computer run of
<somebody's> Ant, the one with rules [fwd 1][L or R according to
colour of square][invert previous square].  This was quite well done.

These lectures get quite a good audience I believe, and though he
didn't mention Fractint, the overall presentation was interesting and
hopefully would encourage some younger viewers to investigate
further.

I would also create a subdirectory for your frms and put them in
there.

Probably most of us don't know what to put in there. So we
just plug in different numbers, etc and see what happens-
often good things do. :) If the box needs a function rather
than a number just press the left or right arrow key to
cycle through the functions. I hope I understood your
question correctly.

>and I thought there was

Press the 2 or SHIFT-@ key on the top row of your keyboard.
This will let you load pars into fractint.

When fractint runs a par that requires an external formula, fractint
looks wherever you stored your formulae and reads everything
there until it finds (or doesn't) the formula it needs. But if
you set up a par subdirectory as recommended, you have to tell
fractint you did this. You tell fractint by creating an
SSTOOLS.INI file. This is just a text file that fractint
will read when it starts up. My SSTOOLS.INI looks like
this:

[fractint]
TEMPDIR=c:\windows\temp
WORKDIR=c:\fractint
PARMFILE=c:\fractint\parms\jaxdev.par <--- a default par file (optional)
                                           the important part is

All this information is included in the Fractint help but it

Fractint is great but not very friendly by today's standards.
It seems to be written by programmers for programmers.

I hope this helps.

Not sure. We were thinking of buying a plane but decided on
a sailboat instead. So that makes JM about 10 years old. MJ is
perhaps 5 years old. Even though M and I are former
photographers we have almost no pix of each other. I used
what we had because a member of this list (who shall remain
nameless) insisted that we must have pictures of ourselves
displayed. Her contention was that only females did this
because men lacked the courage :)

At any rate, M and I are both grayer now. M went first but
I only turned gray because I thought it was the polite thing
to do. We just got a digital camera (still not used though)
so some-day-real-soon-now we'll display more recent
photos. I think you will find our pages will then become
more, shall we say, mature... I'm 50 and M has her usual
10% up on me.

Yep. That was the start. So how would you judge my predictions?

I went on to set up my But is it Art page and Name the Artist
pages but the responses to them have been pretty minimal. Not
enough interest I suppose... sigh. I think they will be the

Jack....

I enjoyed the Name the Artist pages......no reason not to leave them up for
a while if you have the space.

For our next contest....someone ought to write a  little program that
allows the computer to randomly generate fractals and apply colors.....say
for a couple of days.....and save them.....and also "selects" 3 images to
submit to the contest. Part of the fun could be guessing "who" the computer
is....what do you think??? If most of us guess right....I think that would
be very indicative that fractals are more than just math.  BTW...my
computer scientist son was babbling about a mathematical proof that
computers are limited....can't remember quite how...but we were discussing
the fractal art conundrum.

Now, the rookie speaks:

I think you've opened up a tasty can of worms, and let me be one of
the first to gobble a few...

Although I am not a degreed CS type (I have a physics BS), I have
my own take on the topic.

Computers are limited, as are we humans, by their wiring and
programming.  Digital computers are designed for crunching numbers.
Making them do more requires analog interfaces to the outside world
(i.e. video (cards, monitors, cameras, scanners), audio (cards (as
always), mic's, speakers), tactile (keyboards, mice)) analogous to our
senses (of course, systems to replicate taste and smell also exist, but
most of us have no reason to provide our computer with those capabilities).
Our brains, on the other hand, have been designed by billions of years of
biological evolution to drive a number of complex behaviors necessary
for survival, and our sense of aesthetics has been affected by *at least*
ten thousand years of cultural evolution.

In spite of computers' limitations, they really lack only two layers of
capability: 1) a neural net to replicate retinal and visual cortex circuitry,
and 2) software to develop, categorize, store, access, and update style
and preference data.  Similar efforts to optimize computing for specific
tasks have proven successful to various degrees (i.e. "Deep Blue"
(chess), the CAM projects (Cellular Automata Machine), Digital Orreries
(high-precision, high speed orbit propagators), optical target tracking,
prime number crackers, and walking robots with controls based on insect
nervous systems), and I suspect the same could be done for fractal art.
The problem is that to do it right would take big bucks and mental effort
worthy of a PhD (or several).

For now, I suspect you would be disappointed with the results of a
"pure" computer generated effort (on the other hand, some of you
might be able to blow our socks off; life is full of surprises!).  However,
allowing human intervention at one or more points in the process could
make the contest a whole lot more do-able.  These might include:

1) Provide, in addition to Fractint's default random palette capability,
 a dozen or so favorite palettes to select from.

2) Leave selection of the final submissions to a person.  What computers
 lack in creativity they make up for in their ability to tirelessly crank out
 variations.

Anyway, it's an interesting idea!


Hope I didn't bore y'all, Bud

   It is provable that the problem-solving ability, meaning the ability
to answer a given question, of any computer is equivalent to that of what
is called a Turing machine. It is fairly easy to also prove that there
are problems which, despite having quite definite solutions, cannot be
solved by a Turing machine and thus any computer. This, and related
discoveries of early-twentieth-century mathematics like Godel's theorem,
are probably what your son is referring to... Note that from a scientific
standpoint, the term "computer" as used here includes a computer like the
human brain.
   Note also that the determination of what problems are and are not
solvable is often a tricky task that people spend whole careers on...

If this doesn't make any sense to you it might be because I

Oh, I forgot another obvious example, in light of recent developments:
music!  I think if we were to ask someone in *that* field, we might get
more optimistic and perhaps helpful input.

No, it doesn't.  The human brain is not a Turing machine in any shape or
form, and does not work algorithmically.  Hence there are propositions
(Godel's theorem being the first example) which we humans can see as
"obvious" (or least mathematicians can!), but are provably impossible for a
computer to "understand".

Many people may think this is heresy, but I think it would be preferable to
having half of the list devoted to how mailers manage to mangle text

It might even be possible for the mail server to automatically gather up
all the par files and put them into a "best of fractint-digest" collection

   er... not sure I know what you mean by "see as 'obvious'" or
"'understand'" here. I don't know how to discuss what a computer does or
does not "understand". A computer, however, can certainly re-create the
proof of Godel's theorem by following the same logical steps.

   To clarify my previous statement, which is admittedly controversial as
stated: From the standpoint of theoretical computer-science modeling of
computing, no aspect of the human brain which has been found
scientifically describable, appears to be exempt from the models of
automata theory which leads to the proofs about Turing machines. This
does not suggest that we understand processes of thought or that emergent
properties cannot exist; but assuming that all functions of the brain do
in fact ultimately depend on the physical nature of the brain, all
its low-level physical or chemical processes can indeed be modeled as
automata, and the proofs do thus apply.

   It is entirely possible to disagree with this statement on religious
or mystical grounds and I freely accept that our scientific knowledge of
the brain is as yet quite insufficient to describe it fully; however, to
the extent to which we can describe it, this appears quite clear.

This is going to cause more problems than it solves.

It requires attachments, which have already been voted down.
It adds two extra layers of encoding, making two extra places where
    things can go wrong (zip + uue)
Uuencode is less portable than base64 encoding, upon which MIME is
    based.
Since uuencode (and base64) expands source material by 1/3rd, its not
    clear that anything would be gained by taking a text file and
    compressing it and then expanding it again.
All PAR/FRM/IFS/etc. files are text files -- treating them as binary
    attachments makes them unavailable to text search engines that
    search through the list archives.

In summary... just deal with the plain text files.  There will always
be problems with embedded text files, all of which are solved by the
use of MIME (an existing standard).  However, until the majority of
people (or at least the ones who complain about MIME) get MIME
compliant software, I don't see MIME approaches being accepted.

I found that section of your website interesting.  The easist images to
recognize were from Earl Hinrichs (almost instantly) and Linda Allison.

But this was a "trick" question:  twelve images shown, nine artists
listed in the side bar, two listed in the fine print (at the bottom),
and one unlisted unknown.  Not exactly a one for one match.

P.N.L.

I keep seeing this problem about Paul getting his messages bounced
back.  I haven't seen what address he's posting to -- he should post to
[e-mail], NOT [e-mail] since
lists.xmission.com now handles all list traffic for xmission and list
mail sent to any other machine will bounce.

If Paul is using that address, but still having problems with the
messages being bounced, he should forward one of the bounced messages
WITH ALL HEADERS INTACT to Tim Wegner <[e-mail]>, list
administrator.

With a sample bounce, Tim can work with the folks at xmission to sort
out the problem.

Date: 06 Jan 1998 16:35:13 -0500

Beth,

   I'm sorry you're having so much trouble recreating the images posted
here as parameter entries. One side effect of the center of gravity of
Fractint discussion moving from the CompuServe forum to this message list
is that a majority of new images are now posted as part of messages rather
than in the traditional .par and related files. Getting from a message to
an image drawing on your screen does take a fair amount of knowledge of how
Fractint works. I'll try a step by step explanation of how to do it; I hope
it solves your problems for you. If not, let me know, and we'll keep at it.

   First, make sure you have the most recent version of Fractint, currently
19.6. Each new release incorporates new features, and many current postings
will only work with the latest version.

   Second, a word about directories. Unless you give instructions to
Fractint to the contrary (via special command line options or in a file
called "sstools.ini"), Fractint will look for all relevant files in the
same directory where Fractint.exe is located. Starting off, it is probably
easiest simply to use the one directory. As you get more familiar with the
program, you will learn how to create separate subdirectories for the
various kinds of files, and how to tell Fractint where those subdirectories
are.

   Finally, the information which Fractint uses to draw an image is
contained in entries with the form:

Name  {; comments
  various commands
}

The relevant entries are

   1. Parameter entries. These are entries with commands such as type=xxx
colors=lots_of_Martian, etc. Usually, the first command is "reset=####",
where the #### is the version of fractint which was in use when the entry
was created. Don't worry about that; if a version earlier than 19.6 was
used, the current version will still draw the image.

      Parameter entries contain all the information needed for fractint to
draw an image, unless "type=formula", in which case fractint will need to
find the formula. The name of the formula is identified in the entry with
the command "formulaname=xxx". There is also usually a command in the
parameter entry "formulafile=xxx.frm", but this is not important, because
Fractint is quite clever in searching for and finding formulas. More about
that later. "type=ifs" and "type=lsystem" also require fractint to find the
relevant ifs or lsystem entries, but postings with these commands are
reletively rare, so I wouldn't worry about that now.

     Parameter entries should be copied to a file with the extension
".par". You can use any name you want for the file, such as 1998msg.par.
Just copy the text of the message to the .par file, and then edit it to
delete everything except the parameter entry or entries contained in the
message (in each case beginning with the name of the entry and ending with
the "}"). The .par file should be in your Fractint directory, as I
discussed above, unless you have explicitly specified a different
directory. Don't delete the original message if there are formulas in the
message! Those entries will be copied to a separate file.

   Occasionally, problems are caused by the email software which people use
to post these entries. Take a look at each entry; there should be no blank
lines, and for the long commands such as colors=, the last character of the
intermediate lines should be a "\".

   2. Formula entries.  When the parameter entry is "type=formula",
fractint must find the named formula in order to draw the image. A formula
has the same overall structure as a parameter entry, i.e.

Name {; comments
  various calculation instructions
}

and are pretty easy to identify; they have assignment instructions such as
z=pixel or c=sin(pixel); a ":" will appear somewhere in the formula; and in
some you will see flow control instructions such as IF (x==y) etc.

   Formulas need to be copied to a file with the extension ".frm". Any name
is OK, such as "1998msg.frm". The file should be in your fractint directory
as discussed above unless you have explicitly specified a different
directory as a command line option or in sstools.ini. Edit the file to
delete everything except the formula entry or entries. If an entry name is
preceded with "frm:", delete the "frm:". This is a feature which permits
the formula to be included in a .par file, but it is a good habit, I think,
to get the formulas into files with the .frm extension. That way they will
be available for general use and not just the initial drawing of the
related parameter entry.


   3. Ifs and Lsystem entries. The general format is the same, but the
information in these entries looks quite a bit different. They should be
copied to files with extensions ".ifs" and ".L" respectively, and any
preceding "ifs:" or "lsys:" edited out.


Now, to run the parameter entry.

   1. Go to your fractint directory and start Fractint.
   2. Select your video mode.
   3. Hit Shift-2 (the "@" key). This will probably bring up a list of
parameter entries in the default .par file "fractint.par".
   4. Hit F6. This exits fractint.par and shows you a list of .par files in
the default directory. Presumably, your 1998msg.par will be one of them.
Put the cursor on it, and hit <CR>. This will show you a list of the
parameter entries in that .par file.
   5. Move the cursor to the entry you want to draw, and hit <CR>.
   6. The image should start drawing. Enjoy.
   7. You can zoom, change parameters, and do anything else that fractint
permits you to do with an image. Important commands to do these things are
Page-UP (for zooming), and "x", "y", and "z" for changing various options.
You can save the image by hitting "s". You  can create your own parameter
entry by hitting "b" and entering the requested information.


Finally, if you want to draw your own image using a formula, hit "t" from
any image screen or the main menu, select type "formula", and hit F6 to get
out of the default fractint.frm list of formulas to see a list of .frm
files. Select the file you are interested in, hit <CR>, and select the
formula you want to draw. Before drawing the formula, Fractint will show
you the formula text and provide space for entering user specified
variables (p1, p2, and p3) and user specified functions (fn1, fn2, fn3, and
fn4), if any. You can change your selections at any time the image is
drawing by hitting "z".

   That's a long message! Let me know how you make out.

George Martin

Beth:

Mark and George answered your question quite well.  There is one concept that
may not have come through clearly:

A named par file consists of parameter sets for a number of named Fractint
images.  During December, 1997, for example, there were a whole bunch of sets
of image parameters that were included in messages from the various subscribers
to this list.  I selected and copied them all, one by one, into a single par
file that I just called Dec97.par.  George described how to use <2> or <@> and
<F6> to get to the par file, then arrow up or down to the image you want.

Essentially the same scheme applies to formula files.  A named frm file may
contain many individually named formulas.  I placed last month's formulas, for
the most part, in Dec97.frm, for example.  In a couple cases the message
contained a full file of formulas that I saved under the name used by the
sender.  Again, George described how to start with <t> to get to any individual
formula file you want.

Of course, if you want to generate a particular image, the formula called for
by that image must be present somewhere in the Fractint directory.

Since you are new to Fractint, maybe you are not aware that par and frm files
are ASCII text files.  You can examine how they are put together by using a
text editor or your word processor in .txt mode -- just open the name.par or
name.frm as you would any other document and look it over.  In fact, you can
use your editor to make changes directly in the par parameters or in the frm
files -- and that is what you have to do if the color  or other parameters are
garbled as George mentioned.

I think your best bet might be to play around some more with the 'standard'
formula and parameter files that come along with Fractint and not worry about
downloading and implementing the ones in these messages until you have the
'standards' mastered.

Dick

I've been enjoying generating lots of the wonderful fractals posted on
the list, especially the fantastic 3Dballs series with variations. This
all came to an abrupt end when I downloaded somebody's files infected
with the dreaded "=3D" disease. Full of confidence, I found and replaced

Can any kind soul send me directly all the ball-related par and frm

This question is one I have wondered if fractals might be a good application for
(what a horrible sentence that was, eh?)... E.F. Schumaker (a philosopher)
points out that there are basically two types of problems, convergent and
divergent.  For a convergent problem, many starting solutions can be refined
into a single, optimum solution.  I think the evolution of the bicycle is the
example he gives for this... a divergent problem, on the other hand, has two (or
more?) optimum solutions, and which solution is the right one becomes a matter
of intrinsic or personal values. Ask any statistician and she will tell you that
values are too flighty to be modelled - enter fractals.  Or at least, that's the
idea.

Asleep yet?  :)   Jason

Here's my hunch: recent progress in the field of quantum physics has revealed
that information can travel faster than the speed of light between two particles
that once interacted.  This phenomenon has been experimentally proven (1).  What
if our brains make use of this phenomenon, and are able to receive information
in a similar manner?  The experiment in which information was shown to travel
faster than light doesn't dare to suggest a *medium* for the transfer, but what
if our brains can access this medium?  If this could be proven, it might shed
light on all manner of 'otherworldly' phenomena (I'm especially interested in
the contagiousness of yawns... :)  To be sure, I'm below novice status when it
comes to these topics, but what I've read doesn't seem to negate the
possibility.  And of course, fractals will come into play at some point...

Put that in your snipe and poke it!  Wonder, Jason

I'm sorry about that and certainly didn't intend any "trick". I
didn't include Margaret's or my name in the side bar list
because we don't view ourselves in the same league. But I did
include our names at the bottom of the pics where I assumed
everyone would find them and understand that our images were
included. Perhaps this assumption was incorrect. The 12th
pic by Ann Onimusse was supposed to be a joke (the name
should have been a clue). It backfired as I got a lot of email
asking who Ann was.

I was curious to see how many would attempt, via email, to
guess her identity. The only one who did was Sylvie Gallet
and she was pretty damned close! In my defence, I would say
that police suspect lines-up often include a ringer. I don't
think this was really cheating, just a surprise twist for a
minor added complication. After all, conceptually the guess
procedure was not compromised. But if others also think this
was a cheat say so and I'll remove Ann Onimusse.

Jack....

This helps enormously!!!!! I modified my sstools.ini file with GREAT
trepidation based on the ......ahem.....help .....provided at the fractint
site.  Your explanation is MUCH more complete and it is my suggestion that
Noel incorporate it into the fractint documentation dealing with
sstools.ini.   One very basic thing that was NOT explained is that one gets
sstools2.ini in the fractint package.....and to be useful the file needs to
be re-named after the desired changes are made.  I think everyone has done
a marvelous job with the documentation for fractint.....but that questions
like Beth's point out where additions need to be made .......we all have a
knowledge base we tend to forget about when trying to explain something and
that inhibits the transfer of information to anyone who is not at our level
in a particular area.

Thanks again both to Jack and Beth

WE INTERRUPT WITH THIS SPECIAL WARNING:

It has recently come to my attention that Pandora,
my computer, has subscribed to this list under my name and
without my knowledge or consent. Any comments from her
with which you agree she probably overheard from me. The
rest were undoubtably her own opinions. She is also

Paul....

thank you so much for another marvelous formula.  I have a question
regardring the color mapping...it is unusual in that it is not smoothed
from color to color...but it fits perfectly with the image.

This leads me to guess that here is some sort of mathematical relationship
between the colors and the formula...am I right??? or did you get tha
perfect color set just by hard hit and miss work???  It was truly
lovely...and I am looking forward to messing around with the formula

Peter: I found myself in the same boat. I did a little research and =
found out that the forward slash accented a is defined as ASCII decimal =
value of 160.=20

How do you get that? Well, you start with the Num Lock on. Then press =
the Alt key and hold it down. While holding down the Alt key, key in 160 =
on the *number* pad (not the keyboard). When you let up the Alt key, =
viola, you get an accented a like this =E1.=20

This doesn't work in PFE (as previously suggested) or Notepad or =
Wordpad, but it does work in my old DOS text editor. I can see the =
accented a's and I can do a "search and replace" and clean out the file =
just as slick as you please. Give it a try and let me know how it works.

I'd be delighted to add any improved docs to Fractint. In fact I'd
encourage folks to submit improvements. Remember, Fractint is a group
project. Helping with docs is a way non-programmers can participate.

One little know secret is that with the help compiler hc.exe that
comes with the Fractint source code, anyone can edit the help source
files and add them to Fractint, as long as the hypertext links are
not changed. I'd be willing to post the hc.exe file if anyone wants
to try this.

I'm asleep at the switch, so if someone (preferably Jack, since he
is the author) could email me the improved sstools explanation, I'd
appreciate it.

Personally, subtleties are lost on me, not to mention hints.

I would have listed the name as a choice, and spelled it more like Ann
Nonimus or Naim Less.

Ah, that doesn't sound like a PFE problem - at least I know of no possible
cause.

Perhaps if you email me the offending file, I could have a bash at making
sense of what's going on. In the meantime, you might try TYPEing it in a
DOS window and seeing if they show up there.

You know, I'm starting to get the feeling I'm missing some of the traffic
on this list... I'll look in the archive, but why would I be missing them?

Ah, now I'm sure of it! _Accented lowercase a characters_, yes? á in
ISO entity name lingo!

The thing is, Fractint is reading ASCII 160 as an á - as this is the
code (MS-) DOS assigns the character, while in Truetype (invented by Apple,
remember) and most other fonts used by Windows, including PFE and clearly
whatever your email software uses, ASCII 160 refers to a nonbreaking space.
So that's why you can't see it. So try searching with PFE for "ALT+0160"
and see if that catches what look like spaces in the locations where a's
are turning up in Fractint. To confirm, you can change PFE's screen font
("options>preferences->screen font") to "Terminal" to use a DOS-type font.

   er... not sure I know what you mean by "see as 'obvious'" or
"'understand'" here. I don't know how to discuss what a computer does or
does not "understand". A computer, however, can certainly re-create the
proof of Godel's theorem by following the same logical steps.

My understanding was that it could not.  That is the whole point of Godel's
theorem.

   To clarify my previous statement, which is admittedly controversial as
stated: From the standpoint of theoretical computer-science modeling of
computing, no aspect of the human brain which has been found
scientifically describable, appears to be exempt from the models of
automata theory which leads to the proofs about Turing machines. This
does not suggest that we understand processes of thought or that emergent
properties cannot exist; but assuming that all functions of the brain do
in fact ultimately depend on the physical nature of the brain, all
its low-level physical or chemical processes can indeed be modeled as
automata, and the proofs do thus apply.

This assumes that physical laws are deterministic and algorithmic...

I'm afraid I'm not an expert on this topic, but I refer you to two books by
Roger Penrose, "The Emperor's New Mind", and "Shadows Of The Mind", which
explain all this quite well.

Err? I always get suspicious of philosophers (or philosopher-scientists)
who try to take mathematical or physical concepts out of their home
domain and apply them willy-nilly. So often rigour is sacrificed in
favour of a nifty metaphor or convenient analogy.

The Turing machine proof? Is this the Godelian proof that Roger Penrose
concocted? If it is, then what's the other one (respond privately if you
wish)? I'm familiar with the proof I mentioned, and never _quite_ been
convinced by it.

From Ed Avis:

Not proven. Not enough is known about the human brain to confirm whether
it is a Turing machine or not. It can simulate a Turing machine and do
everything a Turing machine can do, but it is not proven that it can do
anything more. The Penrose objection mentioned above (the best anti AI
argument I am aware of) is, as Penrose himself admits, not rigorous and
crucial points are covered with handwaving.


In my opinion, the whole question is moot. It's quite clear that minds
are _physically_ possible (everyone is their own best existence proof).
So what if it turns out that our notion of computability is insufficent?
It's only our notion and we're quite capable of extending it if and when
it turns out to be needed.

This topic comes at an apposite time for me, as I'm currently attending
a conference on unconventional models of computation. Mainly quantum and
DNA models - formal abstractions, implementations, possible
applications, their prospects for exponential speedup of problem-
solving, etc. Reversible logic and cellular automata are also highly
featured. There are considerations on the possible noncomputable
capabilities of some quantum approaches, but since there is no
noncomputable behaviour in present-day quantum mechanics (and hence none
in the rest of physics - hence chemistry hence biology hence brain
function) "computability" for the most part retains its "classical"
sense of "something that can be done on a Turing machine" (though there
is one paper that has yet to be presented titled "Even Turing machines
can compute noncomputable functions").

I regard intelligent, conscious and aesthetically sensitve machines as
inevitable. Eventually. Not yet. My running(!) copy of Windows 95 takes
159MB on disk (though it has no excuse being that large for what it
does), and that is still some way from the 3GB of the human genome
(though I'm sure  Monopolysoft is working on more bugware to force down
our throats!) The largest software application I know of still fits in
executable form on a single 680MB CD-ROM. On the other hand it has been
estimated that memory on the order of 10TB would be needed for storing
a human mind, and probably quite a bit more in an executable form. But
how long ago was it that Bill Gates was saying that noone would ever
need more than 640kB?

I take on the penalty of an off-topic post. If you want to discuss this
with me privately I would be happy to do so.

Looks lovely on my machine. Do you have a collection of pars and frms
somewhere? Peter

Absolutely correct Morgan :)

I can now use PFE to edit the little blighters out!

hmmm... If lots of us have this problem... Maybe Tim will consider making
FractInt compensate for ASCII 160?

Anyway, Morgan thanks for the workaround, much appreciated

Subject: (fractint) Client-server Fractint
Date: 07 Jan 1998 15:52:21 -0000

I was thinking about the forthcoming rewrite of Fractint for version 20,
and wondered: why not use a client-server model for fractal drawing?

The client sends a message to the server, saying "here is the formula to
use, please give me the value of the pixels in the rectangle (0,0) to
(100,100)", and the server sends back the pixels.

The advantage of this would be that it would be easy to add distributed
fractal drawing to Fractint, as well as an easy way to use the full power
of multiprocessor boxes (by running several server processes on the same
machine).  I don't know if any of you have seen the program MandelSpawn
which works on this model.  You can get _very_ fast fractal drawing if you
have a whole network of machines at your disposal 8-) .

It could even work over the Net.  Suppose a two people who read
fractint-digest decide to cooperate.  They both run the fractint server on
their machine, and when running the client, they can get the other person's
machine to draw half of the image and send it back over the Net - and
instantly, you get twice the speed! Of course, this wouldn't be useful if
they were both using their machines at full pelt all the time, but the
typical PC is idle for 90% of the time - time that could be used
calculating fractals.

What do you all think?

Subject: (fractint) another frm and par
Date: 07 Jan 1998 09:11:11 -0700 (MST)

I came up with this formula file while playing with the "bubbles" coloring
method.  The idea is to specify a small range, say 98% to 102% of the
magnitude of c, and to color the pixel (white, say) if the iterate ever
falls within that range, black otherwise.  It creates a graceful series of
loops that get more and more convoluted, showing the fractal shape in
overview.  It seems to work with other formulas, not just z^2+c.  If you
use this, you'll definitely need to use single-pass mode, and will
probably want to anti-alias down from a much larger image to your final
piece.  I will post an image (infinity) done with this formula to the
fractal pictures newsgroup.

frm:minmaxc_jul { ; Kerry Mitchell
    ; colors the screen one color if the iterate falls between the
    ; high and low bounds, otherwise leaves it blank
    ; Julia set--c=p1, bailout=real(p2)
    ; low and high bounds are set through p3--
    ; center of range = real(p3)*|c| (try 1)
    ; width of range = imag(p3) (try 0.05)
    ; color with single-pass mode and decomp
        zc=pixel, c=p1, r=real(p2), z=1
        rc=|c|, k1=real(p3)*rc, k2=imag(p3)*0.5
        lo=k1*(1-k2), hi=k1*(1+k2):
        zc=sqr(zc)+c, rzc=|zc|
        if ((rzc>lo)&&(rzc<hi))
          z=-1

Peter,

 - I found myself in the same boat. I did a little research and found out
 - that the forward slash accented a is defined as ASCII decimal value of
 - 160.

Congratulations, you've just discovered the extra space character in the
Windows character set (which is different from the DOS character set).  For
example, in Windows, the forward accented a is code 225.

Incidentally, any web page using a non-breaking space will generate code
160 in a Windows browser, and if you copy/paste in another app, you get
this.  If you want to search/replace non-breaking spaces in a Windows text
editor, enter ASCII code 160 (in the method you describe) into the "find"
portion of the dialog.  I use TextPad rather than PFE (personal preference)
and this works fine for me.

Hi Sylvie,

I get everyone's post just fine. It is, as discussed at length on this list
a combination of certain folks email sender and others email reader.
I use Micro$oft Internet Mail on Windows 95. No problems.
Apparently my posts are readable to all and I can read everyone's
posts.

So I was befuddled, bemused and befumed when
I saw the archive is one of the clueless email readers.
Look at Lee Skinners post  (messed up),  Jay Hill's (fine)
and Morgan L. Owens (fine)  here
http://www.xmission.com/pub/lists/fractint/archive/v01.n064
and Sylvie's (messed up) and Peter Jakubowicz (fine) here

and again Sylvie's (messed up) at
http://www.xmission.com/pub/lists/fractint/archive/v01.n061
Watch the archive for this post. It will show the May-2 formula
just fine but Sylvie's original will be screwed up.

We need an archive free of 3D effects! That is why I posted Paul's
formula on my page, 34k for just his.  (I hope my late last night
silliness was decryptable  :-)  , there were illustrations to go with
the text.)

A complete 1997 collection must be pushing a megabyte
for just the frm + par. A weekly collection posted somewhere
would be useful. Someone mentioned it already, as an
automatic server thing. But if such is another UNIX dummy
collecting =3D effects, forget it!  If someone has a 1997 (& 1996)
collection very well organized (and I'm not sure exactly what
that means) that would be useful. And now would be a
good time to start 1998 :-).

Isn't the Windows character set the same as ISO Latin 1?
See <URL: http://www.htmlhelp.com/reference/charset/>, which gives the
same characters for the different code 160 and 225 as you describe.

There are several client-server distributed M-set programs out there,
I can dig up references.  Portability is a real problem, although its
significantly easier now that winsock has become popularized on
Windows.  However, that still leaves a socket implementation for DOS.
The technology is there, but interoperability and portability of code
is a problem for fractint's limited operating environment as a 16-bit
dos app.

Ed....

This is what I think of as the nice to have eventually category. I'm far
more interested in getting a winfract that....

1. does everything the dos version does
2.  has complete documentation and a dummy proof help utility
3.  runs under nt
4. preserves all the color mapping options I have in fractint and maybe
adds some anti-aliasing post processing or something....
5.  gives me a bunch more filters or formulas or whatever you think is the
proper term for coloring the inside and outside of the fractal (like damien
jone's stuff)
6. an expanded pallet would be nice.....but I'm not sure I'm crazy about
any of the truecolor programs.....and I hate their color control
interfaces.....so there's a problem for you all to solve.

If I can process the fractal as a background application while reading my
email or whatever, I don't really care that my processing time goes from 10
minutes to 5. And by next year I'll cut that time anyway by going from my
100mhz pent to 233 or something anyway.

Here's a variation of ATAN coloring that works well with
many transcendental functions.  This FRM and PAR file
use the COSH function.  Let me know if you're getting

Paul...you bring to mind some comments that I would very much like to see
in all formulas.......first, a hint about what values to put in when
prompted.  It is very frustrating to look at a formula with 6 blank spaces
and not have any combination of numbers work after 30 minutes.  Also, if a
formula requires some sort of resent in the basic or other options, that is
VERY handy knowledge to have.  This morning I was messing with a formula
that needed the decomp thingy (in the basic section) to be set to
256....like NO WAY am I going to know to do that. Having the pars is a
great help....but having that type of info in the formula itself saves
having to hunt for the par or gif that starts you out on the right foot.

Subject: (fractint) Ideas for future versions of fractint
Date: 08 Jan 1998 12:42:06 -0000

Here are some ideas I've had for the next versions of fractint. Some
or all of these ideas might be impractical or impossible, so don't
shoot me down with flames if I'm spouting rubbish.


Previous versions of fractint have generated fractals by using
several layers of program. These are the layers for escape time
fractals:
  1) Drawing mode algorithm (solid guess, boundary trace, 1-pass,
     etc.) - this gives a screen pixel
  2) Zooming and panning (also rotation, stretching and skewing) -
     this transforms the screen pixel into a point in the complex
     plane.
  3) Non-linear transformations (i.e. inversion) - this transforms
     that complex number into another one, which is used as the
     starting point for...
  4) The iterated function - the outputs of which are:
       the iteration count
       what caused the calculation to stop (maxiter reached, bailout
       reached, or periodicity check kicked in)
       the last value of z
     These are used in...
  5) The colouring algorithm, i.e. the inside=, outside=, decomp=,
     biomorph=... options. This gives a number 0...255, which is
     used to dereference the...
  6) Colour map - which is used to colour the pixel specified by the
     drawing algorithm (this is done by the hardware).

The next versions of fractint should follow the same plan, but the
addition of truecolour modes means that colouring needs to be done a
little more inventively.

Rather than have (5) output a single integer, it should output a
real number. This can be used to look up the colour in a colour map
which, rather than consisting of discrete list of colours, consists
of a short program which accepts a single real number and outputs
three real numbers (red, green and blue). For example, if all three
outputs were set to be the same as the input, you would get a smooth
transition between black and white. Of course, old fashioned maps
would still be supported, but there should be an option to make the
transition between adjacent colours in the map smooth, so it can be
used for continuous potential images. This way, assuming that the
screen can be redrawn fast enough truecolour images can be colour
cycled.

Better still, some colouring algorithms might output several real
numbers, each of which can be assigned a different colour map. These
could be colour cycled seperately, with different speeds and
directions. Then you also need an algorithm to specify how to
combine the outputs from the colour maps. For more information on
this technique, have a look at the amazing program "Chromazone for
windows" (written entirely in assember). It isn't a fractal program
(at least the version I have isn't) but it does have a fantastic
colouring facility.


Similar layering can be worked out for orbit fractals, .IFS and
Lsystem - the main difference is that (2) and (3) are done
backwards, and in reverse order (an ordered pair of real numbers are
used to work out a screen pixel).

For some fractals, e.g. bifurcations, you need to do (2) and (3)
both forwards and backwards, because you scan along the screen but
plot vertically.

Diffusion fractals and any other odd ones do their own thing.


Now, this is a Windows 95 program, which means
a) We can have images at any size - full screen mode or window mode.
   For window mode we need to specify the size of the window. For
   both modes we need an option to specify how many pixels are
   calculated for each screen pixel. No need for disk-video modes
   (the image must be stored in memory anyway, in case the window is
   hidden) - for images larger than the screen, you can view the
   image at half size, say, as a "preview" for what the "disk-video
   mode" is doing (of course, windows handles whether memory or swap
   file is used for this). I hope this makes sense.
b) Printing is much neater using the windows printing engine. A
   "print preview" should be implemented which supports scaling and
   centering (see the equivalent feature on Paint Shop Pro).
   (The print option in the DOS version of fractint, if it is to
   continue (and it should) might as well be taken out, and maybe
   put into another program. I'm sure there are much better
   dedicated programs for printing .GIF files.)
c) Background fractals: fractint can take over all the idle cycles,
   thus making background fractals without slowing down your
   computer (much).
d) Screensaver. If background fractals are enabled, presumably this
   would simply show the fractal currently being drawn. If no
   fractals are being drawn, it could just display a (colour cycled)
   slideshow of saved images.
e) Output file format: you can have as many as you like using output
   format filters. Ditto input format filters.
f) Mouse controlled 3D rotation to set parameters for setting 3D
   parameters.

For background fractals, it would be useful to be able to have a
"batch list" which you can add your pars to so it can calculate all
the images, one after another. You should be able to promote or
demote images within this list, and maybe keep multiple lists.

Fractint should have a built in editor for .PAR, .FRM, .L, .IFS and
.MAP files (especially with the new, complicated colour maps), plus
any other new similar filetypes. Also features to help organize
these files, such as having a hierarchy of "subdirectories" inside
.PAR files, which can contain other images and subdirectories, etc.

Email-ready output: output a .PAR file which contains all the
information needed to generate the image - colour maps, formulae,
everything. That suggestion will be popular with this list.

When reading such an email-ready file back into fractint, the
necessary bits and pieces can be seperated out and put in the right
places in the hierarchy, thus eliminating wasted disk space if the
reciever already has the right bits.


Drawing mode algorithms. Instead of having 1-pass, 2-pass, solid
guess seperately, you could have a single "n-pass" mode where you
specify "n" and an option to "calculate all pixels" or not. A new
algorithm could be to calculate the pixel which is furthest away
from all the other pixels already calculated. This isn't as hard as
it sounds, and would give a quick preview of the image. It could
also be adapted to be an improvement on the solid guessing
algorithm.

Maybe there could be an option to recalculate pixels where it looks
like the guessing algorithm has guessed wrong, like a paint program
(just wave your mouse over the pixels you want to recalculate).


More options and user defined options for stage (3) above. Currently
fractint only has inversion. Maybe this could be extended to
twisting, z+1/z transformation... How about the equivalent of a
"zoom box" for these (of course, for inversion, it would be what is
outside the box that is actually drawn, rather than inside).

Put built in types on the same level as formulas. It seems that most
fractals on this mailing list are of type=formula. You should be
able to write type=<formulaname>.

Lots more colouring algorithms, including field lines (which I think
has been cracked now - the thread on field lines, decomposition and
texture mapped fractals can be read at
"http://homepages.enterprise.net/berrypark/andrew/field.txt".
I gather these lines are at right angles to the isolines of the
continuous potential colouring (which is not be the same as the
electrical potential if the inside of the set contains uniformly
distributed electric charge, something else altogether). If so,
using these and cont-pot you can do all sorts of exciting
colourings, including texture maps.

User defined colouring algorithms, to make .FRM files simpler (at
the moment we seem to have .FRMs for iteration formulas, .FRMs
for colouring algorithms and .FRMs for each possible combination.

User defined bailout conditions.

Now, if (the most significant bits of) the output from (5) is stored
rather than the colour, you can change colour maps without
recalculating. Better still, if you store the output from (4), you
can change the colouring algorithm without recalculation, although
this could be impractical because of the amount of data that needs
to be stored, especially if you start storing lots of values of "z"
rather than just the last one. Store a flag for each pixel saying
whether it has been calculated or not, and you can switch drawing
modes without starting all over again.

Symmetry could be smarter - currently switching on decomp switches
off symmetry. Is this really necessary?

Higher level functions - it would be nice if some of these could be
built into fractint, but if not it would also be nice if user
defined functions could be written and used in "fn" types as well as
formulae (and even new colouring, colour map, bailout algorithms).

Algorithms for working out the optimum values of bailout and
maxiter?


Wow, this file worked out to be a lot longer than I thought it would
be, and fractint is already a fantastic program. Sorry I've been
lurking so long - I wish I had more time for messing about with
fractals. Sadly that may be one problem that cannot be solved
with a new version of fractint.

Clearly you are headed toward a PhD in Fractint........good suggestions!!!
In the mean time can we just have a Winfract that does everything the
current dos version does???

Date: 08 Jan 1998 11:43:35 -0500 (EST)

   OK, I'll have one last go at this (rather off-) topic:

   Godel's theorem, which Penose presumably cites, states that in no
system (meaning set of rules and axioms) complex enough to describe
itself (ordinary formal logic could be an example of such a system) can
it be shown that the system both complete (meaning that all true
statements about the system can be proven in the system) and consistent
(meaning that no paradoxes can be derived in the system.) This means,
for example, that it cannot be proven that any of our systems of
mathematics is 'perfect'. This proof is not particularly recent; it
occured in the first half of the century, though I find I can't remember
when...

   As for the paper mentioned stating that Turing machines can compute
uncomputable problems, I'd be fascinated to hear this...

   Ed Avis made a comment which I believe to be erroneous regarding the
ability of Turing machines to model physical law. Nondeterministic sets
of rules are quite within the understanding of automata theory; they are
described as "nondeterministic finite automata" and are certainly
modelable as Turing machines. The universe might not be so describable
were it not finite (possessing a finite number of rules and a finite
space) but it is generally felt, though certainly not proven, that it is.
   I suppose that when I refer to a finite number of laws or rules, I am
implying that the universe is "algorithmic" in the sense that all of its
behaviors are describable by some set of rules. It is certainly
concievable that this is not so, but I would have to say that such a

Instead of removing all "3D"s, replace all "=3D"s with "="s, since there
are valid uses of the string "3D" in some pars and frms.

Err... no, the list server doesn't have anything to do with this
really.  It isn't the source of the =3D's nor is it interfering with
their removal.  The problem lies in having everyone use MIME
compatible software.  The compuserve software generates
Content-Transfer-Encoding: printed-quotable when it isn't needed.  If
that software were doing something more reasonable (like assuming US
ascii, or at least letting you set it as a preference), then there
wouldn't be a problem.  I've looked back over all my fractint messages
that are plagued with =3D disease and they all come from compuserve.

hmm, I DO care if the render time goes up...
Win95 has a horiffic processor overhead, and while this is
fine on a fast machine (most programs dont use very much
processing power) for processor intensive work (like fractal
and 3d rendering) DOS is better by far - up to 2.5 times
faster on my machine.
Until microsoft come up with ways to multitask DOS apps I
think I'll stick with the good old reliable DOS mode, even
if they came up with an easy way to allocate system
resources Id be happier.
I dont see any reason why I should have a fast machine yet
only use a fraction of its power just because thats what
Uncle Bill has decreed.

There is another issue as well...ie graphics modes.  Windows
is very strict about screen resolutions, and would you
really want to restart your machine every time you wished to
change resolution?

Date: 08 Jan 1998 18:29:24 -0000

I've been reading some responses to my suggestion that Fractint v20 should
run on a client-server model.  The consensus seems to be that it would be
nice, but might be difficult to implement (especially in DOS) and that
other features should come first.

In some ways I think that client/server Fractint could actually be easier
to develop than the present form of the program.  The reason for this is
that the server part would be the same across all platforms (DOS, Windows,
Unix, whatever).  The platform-specific code could be isolated into the
client part.

This would mean that Winfract and Xfractint would stop lagging behind the
DOS version in terms of features.  If a new formula or new calculation
engine is introduced, it gets added to the server, which is the same on all
versions of Fractint.  (Of course, some would also require enhancements to
the client, but most would not).

There is a TCP/IP library for DJGPP (and threads packages), so if the DOS
version will be compiled with DJGPP (as seems likely), portability to DOS
should not be a problem.  Similarly there are good Winsock implementations
for Windows.

On the other hand, I'm not one of the Fractint developers, so their
opinions on what would be "difficult", and what features are higher
priority than others, carry more weight than mine.

   The client-server model is clearly elegant, but definitely introduces
overhead. Would anyone with a really deep knowledge of communications
protocols, processor cycles, and fractint's current design care to
comment on how much overhead we're talking about? I mean, if calculation
is 80% of fractint's drawing time on a typical Pentium, and drawing is
20%, would some sort of multithreaded client-server design add on another
20% of time, or 600%, or what?
   I suppose 'multithreaded' is something of an assumption; to some
extent you could separate out the two sets of routines (calculating and
drawing) without really slowing down the code... hmm. Don't know enough
about fractint's design, do I.

The server part also has platform-specific code.  For instance, the
Pentium has 80-bit floats, but IEEE doubles are 64-bit floats.  The
new 64-bit SGI machines might have a "double" that is 128 bits.  Since
fractint switches from floating-point arithmetic to arbitrary
precision arithmetic when the floating point code runs out of
precision, it needs to know the sizes of the various floats and doubles
in order to know when to switch.

Xfractint doesn't lag the DOS version at all.  They use the same code
base.  However, winfract lags because it is a completely different
kind of port to windows that doesn't share the code the way the
xfractint port does.  Fractint should be made more portable so that
contributions to the engine part of fractint can be shared on all
platforms, modulo the compatability issues discussed above.

If any networking is introduced into fractint, it should be TCP/IP at
this point.  There was a time when IPX seemed important in the PC
networking world, but except for corporate LANs IPX seems to be giving
way to TCP/IP in most markets, certainly it looks that way in all new
networking stuff that's created.

I think people generally work on what they think is neat :).

Fractint is currently going through some teething pains as it hits
puberty and outgrows its 16th bit.  Developer discussions I've seen
say that the roadmap for the future looks like: 32-bit flat DOS
application, more integrated ports between X11-unix/Windows/DOS,
24-bit rendering.  I think you'll eventually get what you're asking
for out of fractint, but you're going to have to wait a while if you
want other people to do the coding :)

How the duty cycle splits between display and computation depends very
much on all the inputs.  For deep zooming, distributed processing
becomes a huge win because computing each pixel takes so long.  For
the default M-set screen, the computation can probably be completed
locally before you can even assemble all the distributed pieces into a
picture over a modem.  Typical factors affecting the performance would
include communication speed, processor speed, and scatter/gather
overhead.  I'm not aware of any way of optimally allocating the
resources such that you can always guarantee that you produced the
image in the shortest time possible.  However, its probably reasonable
to build a heuristic that does the right thing 90% of the time.

I like to use fractint with showdot=b/20, but I have noticed that when
the processing time per pixel is short, that this actually slows down
the display.  I think it ends up spending lots of its time bitblting
the little triangle bitmap in and out of the video memory compared to
the time it spends computing the pixel.  However, for very slow (i.e.
deep zoom or complicated formula) renderings the showdot=b/20 overhead
is minimal compared to the total rendering time.  Also, with slower
renderings, I want to know where the computation is more than with a
faster rendering.

Microsoft has some useful items for downloading from their site.  They
are usually referred to as "Power Toys".  One of these is a small
executable to be put into your StartUp path, called "QuickRes".  It will
stay in your System Tray and allow you to instantly alter your monitors
resolution without rebooting.

It has always worked fine for me without any problems.

P.N.L.

This problem happens when you are using an e-mail program that is part

This is only true if you don't change the depth of the pixels.  So if
you switch from 1280x1024 256 colors to 1024x768 16-bit color, you
will still have to reboot.

You can solve this potential problem by enclosing the URL in <URL: >,
as in <URL: http://www.yahoo.com/>.  The <URL: > enclosure has been
proposed as a way to embed URLs safely within other text files and
have them be easily recognized and extracted by programs.

That's just it... the compuserve software isn't thinking at all; it
just puts printed-quotable on every message it sends.  At least, that
is what the compuserve technical support people seem to be saying.

Yes, other people have been sending a few messages that are this way.
However, although I didn't do an exhaustive search of every message
ever posted to fractint, I just looked over the ones I'd gotten
recently.  Of those, the ones with content-transfer-encoding of
printed-quotable were from:

    Lee Skinner <[e-mail]>
    Les St Clair <[e-mail]>
    Sylvie Gallet <[e-mail]>
    [e-mail] (Guy Marson)
    "Steve Jenks" <[e-mail]>

With the two non-compuserve addresses accounting for only 4 messages
out of 42.  Of those 4 messages, one originates from a place on the
globe where iso-8859 is the natural encoding (i.e. europe) and the
others are in printed-quotable because of the way Steve Jenks appears
to have configured his email program.  (Microsoft Outlook Express)

There is one strange one however.  Clamcake forwarded one of my

Excuse me, but you are incorrect.

Have you ever used, or do you use, the "QuickRes" utility that I
mentioned???

I can go from the following modes back and forth in only about a second
with no reboot what-so-ever:

    640 x  480  @  256 color (8-bit)
    800 x  600  @  256 color (8-bit)
   1024 x  768  @  256 color (8-bit)
   1280 x 1024  @  256 color (8-bit)

    640 x  480  @  HiColor (16-bit)
    800 x  600  @  HiColor (16-bit)
   1024 x  768  @  HiColor (16-bit)
   1280 x 1024  @  HiColor (16-bit)

    640 x  480  @  TrueColor (32-bit)

Besides, "Bagpuss" only mentioned changing resolutions (the number of
pixels in the image horizontally and vertically).  Nothing was mentioned
about the amount of colors available (even though it may be done without
reboot).

Resolution is the amount of definition and clarity in an image.  The dot
pitch of a CRT display monitor affects resolution.  However, resolution
is usually measured in terms of the number of pixels ("picture elements"
or screen "dots") per square inch.  By varying the display device driver
the operating system is using, a user can vary the resolution of the
monitor by changing the number of lines on the screen and thereby
altering the number of pixels.  For example, one could reset a Windows
setup to select a driver that provides an 800 (horizontal) by 600
(vertical) line display.

The upper limit of resolution for most PC monitors is about 72 to 100
pixels per inch. As a comparison, most PC printers offer 300 to 600 dpi
(dots per inch) resolution.

Yes, and it required me to reboot if I changed the pixel depth.

Must be something unique with your system setup.  I have been using is
for around two years now without problems.  And all of my friends and
work associates that use it have never had any problems either.  In
fact, there are thousands of individuals that use this.

Maybe you should try downloading it again from:

   http://www.microsoft.com/windows/windows95/info/powertoys.htm

And then give it another try.

I'm using P166 Win95 version 4.00.950 B and not the greatest
amount of video RAM. I'm not using QuickRes, but I can
change among these without rebooting

    640 x  480  @  256 color (8-bit)
    800 x  600  @  256 color (8-bit)
   1024 x  768  @  256 color (8-bit)
   1152 x  864  @  256 color (8-bit)

    640 x  480  @  HiColor (16-bit)
    800 x  600  @  HiColor (16-bit)

But if I want higher resolution I can get

   1280 x 1024  @  16 color
Going to this one I must reboot.

I think there is a Win 95 version dependency here.  An older
version on a P200 with bigger monitor and more RAM had
to boot as I recall. I'll check it again later.

I believe that the reboot requirement depends on your video card.
So as I said before, even though you have the MS "power toy", you
still may be required to reboot when changing video parameters.

This could be possible, or it might have to do with the OS release
level, or drivers and release level, or some combination of these.

Well, not quite what you said before.  But, at least you have revised
your original "will still have to reboot" to "may be required to
reboot".

Question: Is the equation z=cos(z)/z+pixel correct? If so then c=z=pixel
is not needed & should be rewritten as z=pixel. If, on the other hand,
c=z=pixel is correct, why is there no "c" in the equation? In other
words, is "c" being used or not?

Taking Bill Rossi's recommendation of this past Monday, how about...
z=fn1(z*z)/z+c or z=fn1(z*z)+c/z+pixel or fn1(z*z)+c/z or
fn1(z*z)/z+c+pixel or, or, or, etc. etc. etc.

Just putting in my two pfennigs.

re-set with the powertoys thingummy......frankly its easier to run fractint

You can solve this potential problem by enclosing the URL in <URL: >, as in
<URL: http://www.yahoo.com/>.  The <URL: > enclosure has been proposed as a
way to embed URLs safely within other text files and have them be easily
recognized and extracted by programs.

No, please don't do this.  I'm using bgOutlook and it includes the final
">" as part of the URL :-(

Maybe put a space before the end of the URL and the ">".

Rich,

 - This is only true if you don't change the depth of the pixels.  So if
 - you switch from 1280x1024 256 colors to 1024x768 16-bit color, you
 - will still have to reboot.

Not true.  You can switch color depths, too.  The problem is, most graphics
software only checks the color depth when it is first started, so if you
change color depths, the software isn't smart enough to check and adapt.
Closing and re-opening such apps generally is enough to get them to work,
and closing all graphics apps and re-opening them is a far cry from a full
reboot.

I have personally used QuickRes on many different graphics cards, and it
never required a reboot on any of them.  However, I *have* used the "screen
managers" that ship with most brand-name graphics cards; these managers
also provide a resolution-switching option, but they generally *do* require
a reboot.  I typically disable video card screen managers now, and just use
QuickRes. :)

Bagpuss,

 - hmm, I DO care if the render time goes up...
 - Win95 has a horiffic processor overhead, and while this is
 - fine on a fast machine (most programs dont use very much
 - processing power) for processor intensive work (like fractal
 - and 3d rendering) DOS is better by far - up to 2.5 times
 - faster on my machine.

Then your machine is configured incorrectly.  Properly set up, FractInt
running in a DOS box under Windows 95 is only 2% slower.  This has been
covered before on this list.

Hi Kerry,

I'm putting Paul Carlson's in a file which I update whenever he gives
us a new formula.
http://home.san.rr.com/jayrhill/CARLSON.PAR
Ed Avis: how does this work for you? Put the URL on a separate line?
BTW, I have about 10MB of archive of this list from which pars and frms

Question again (I asked this a week ago). What do all you all
think would be the right way to do this? One big frm and one
big par for each of 1996, 1997. Then small ones this year?
What should be included? Enough of the header and test to
ID it and document the formula? Then there is the problem
of cross referencing between them. frm will need a reference
to the names of the sample pars. Anything else?

Jay,

 - BTW, I have about 10MB of archive of this list from which pars and frms
 - could be extracted.

10M!  I thought I had all the messages, but I've got less than 7M of
material.  (Then again, I didn't get that 2.5M file somebody posted to the
list, either...)

 - Question again (I asked this a week ago). What do all you all

A big PAR for previous years should be fine.  If the creators did not
include their name in the PAR comments, edit the PAR to include the name.
The date of posting would also be nice, but not critical.

All FRMs should be in a separate file, organized similarly: author's name
included, possibly date of posting.

Wasn't someone also collecting URLs posted to this list?  Or was that the
Fractal-Art list instead?

Thanks to Jay for purposely piling up Paul's proxy postings.  :-)

What I did, to make his file a legal par, was to wrap comment { and }
around the text part of the pars.  Perhaps this could be incorporated into
the grand par/frm extraction project.

Date: 09 Jan 1998 18:57:11 -0500

Just posted in alt.binaries.pictures.fractals is a .jpg image of a fractal
in a very nice astronomical setting. The image itself is well worth seeing,
IMO, titled eggsplosion, Karl Boehnker.

If Fractint is able to generate something something similar, would someone
kindly post how? I have seen two similar (only in a sense, one was a couple
of spirals in an astronomical setting) pieces before...(BTW, I have also
emailed Mr. Boehnker concerning this...)

After hitting "a", the _only_ thing I have ever been able to generate is a
star field and have never been able to do anything with it. Including when
starting off with a fractal before hitting "a"...

Beginning after the recent contest, I have been collecting most pars and frms that
have come through to my mailbox.  My save format is  something like this:

; Date
; From

; or Comment { ... } if there is a comment  or part of a comment I want to save

formulas or image parameters

But I change as I go - lately, I've just been making a  single comment out of date,
from, and any narrative I want to save.

Up to December 31, 1997, I saved them in Dec97.par and Dec97.frm.  All the pars
are  cleaned up and all draw.  For many of the images, I've modified the comment
lines in the parameter sets by adding the time it takes to draw on my equipment.
If there were formulas without pars to call them, I have only spotchecked.  Some of
the formulas, like the vector and dmj-pub formulas, I've saved in their own frm
files, again with spotchecking on how they run.

There's an exception to haveing all the par/frm sets!  Somewhere along the line, I
lost track of the formula, xmasseahorse.  Maybe somebody could repost that one to
me at my personal mailbox.

Now, I'm working on Jan98.par and Jan98.frm.

I have not taken the time to cross reference the example pars to the formulas
because the formula names appear in the pars and can be searched out with PFE32 or
by visual scanning in an editor.  This should not be much of a problem if I stay
with the month-sized files.

Dec97.par is about 58K and Dec97.frm is about 20K in size.

I don't have much experience in posting except as attachments, which I understand
some of you have difficulty with.  If anyone wants one or both of the above
collections, the vector frms or the djm-pub frms, let me know, tell me how you want
them posted to you, and I'll give it a try.  If the number of people wanting them
is small, it will probably be best for me to send such postings to your personal
mailboxes.

I'm not committing to anything for the future!  I have to travel in my work, and
may even eventually decide to withdraw from this list because of the volume of
traffic -- 60 to 80 messages in one 24-hour period is a bit much!  Sure have been
learning a lot, though and getting many good images and formulas.  So, I'll stick
with it as long as I can.

This last week I have also been going thru the list and sorting frms and pars.
I am still in this year. Next step (nearly impossibe ) to go thru all the

I have collected in 1997, and save them in  appropriate files.

One needs be careful that the part of the comments needed to use
the frm are visible from in Fractint, the part about the parameters.
I notice Carlson's comments use 3 lines for fancy ******* boxes.
This can cut into info space we need to see when working
with the parameters, especially in more complicated frm. I
recommend against such, at least at the top of the frm file.

Here is a quote from one of Paul's frm:

>    ;****************************************************
>    ; Always use floating point math and outside=summ.

>    ; Parameters:

Now there are 3 lines which are not needed. They can push lines like this:

>    ; Note that the equation variable is w, not z.  Always
>    ; initialize z to zero.

right off the bottom of the little window!!!  Not to pick on Paul, but...

Are you using winfract? If not, what fractint version?

I'm going to guess that you're using an older version of Fractint; the
center-mag coord method wasn't implemented until relatively recently.  You can
link to a site to download the most recent version at http://spanky.triumf.ca
Hope that helps,
Jason

Subject: (fractint) Simplgif update
Date: 09 Jan 1998 23:03:34 -0600

I'd like to ask folks on the list who are interested to do some
testing for me.

Fractint's save-to-GIF feature has been reliable for many years.
However, a few years ago, Jon Noring started running into problems
with very large images. Some of the pieces of his giant images
wouldn't save properly, and in other cases simplgif failed to combine
the images made with the divide and conquor method. We studied the
code but could not find the problem. LZW algorithms are not easy to
understand or debug.

For those unfamiliar with this feature, Fractint can make large
images by piecing together smaller images. See the bottom of the <b>
screen. If you set x multiples and y multiples to values such as 3
or 4, a batch file called makemig.bat is created. If you run this,
result is to create a number of small images and combine them in a
multiple image GIF. The simplgif utility combines a multiple image
GIF into a single image. There's a commented out line that does this
at the bottom of makemig.bat, or you can type the command in by hand.

Recently I received an email of a case where simplegif failed
horribly for a very ordinary case. Try the default mandelbrot
using "divide and conquor" parameters of 7x7 at 800x600 pixels,
resulting in an image of 5600x4200. The image is bad halfway through.
(You can view large images in Fractint at lower resolutions - just
select a viewable video mode).

I have added a new (well, new to simplgif) GIF encoding algorithm. It
is based on the Unix compress algorithm. Simplgif now works fine with
the above example. The new simplgif still has the old encoding built
in. Just add a third argument like this:

   simplgif source.gif target.gif anything_here

and the old "pdgif" algorithm is used. Without the third argument,
the new "compress" algorithm is used. As a bonus, the new algorithm
compresses a lot better!

You can get this test version of simplgif via ftp from:

ftp://ftp.phoenix.net/pub/USERS/twegner/simplgif.zip

Please don't upload this anywhere. When we're through testing we'll
release it.

Be warned that simplgif does not save fractal data. Also make sure
you have lots of disk space. Simplgif warns you how much it needs.

I'd appreciate folks trying to find images that don't work with
simplgif. The best way to do this is to make large fractint images.
However, you can copy any GIF image with simplgif.

I'm especially interested is cases that break with the old algorithm
that work with the new, or ANY case that fails with the new
algorithm. You can report back to the list. Or if these test reports
get too numerous and tedious for the list, just email me directly.

If the new simplgif works OK I'll replace Fractint's native encoding
with the same code as well as release the fixed simplgif.

Thanks very much!!!

Tim

George's program offers a way to catalog formulas and to skip duplicate

Subject: (fractint) Liouville Julia set
Date: 10 Jan 1998 01:29:37 -0500 (EST)



I was browsing my copy of TBOF the other day, and noted that the section
on which Mandelbrot points produce what kinds of Julia sets, it mentions
for the edges of components, ones with rational internal angle produce
parabolic Julias, but the section on Siegel disks indicates these only
occur for "sufficiently irrational" internal angles. Later it says the
angle must be "badly approximated by rational numbers" and provides two
criteria, one a convergent/divergent series, the other a Diophantic
equation. Later still, irrational numbers not "badly approximated by
rational numbers" are described as, or as a superset of, Liouville
numbers, and an example of such a number is provided: 1/2+1/4+...+1/2^(n!)
where n! is n factorial. The first four terms in the number are 1/2, 1/4,
1/64, and 1/16777216. Those four terms give the number to the limits of double
precision arithmetic! Note how it is very closely approximated by the
rational numbers that are the partial sums of the terms.

I generated a Julia set from the 'lambda' type using it as internal angle
on the main component (for the lambda type this is the unit disk, greatly
simplifying things, as using L for the Liouville number the Julia
parameters are just the cosine + i times the sine of 2*pi*L). I also
generated one for a known Siegel disk, whose internal angle is the golden
mean, (sqrt(5)-1)/2.

Attached below is the PAR. The Liouville one is fascinating to study using
the orbits window. Generate it and hit o, and look at the assorted orbits
for points in the interior. If that is a Siegel disk it's a damned weird
one. If it is not... what is it?

You found that interesting? Well read Penrose's _Shadows of the Mind_. A
possible explanation is posited there, namely that the brain contains
structures that operate as quantum computers not subject to the
limitations of classical mechanics, nor to the Turing machine's limits of
finite states and finite speed. (Yes, a quantum computer is capable not of
infinite speed, but almost as good, of infinite parallel computation. Some
extended computations that never halt in a normal Turing machine might
stop in finite time run infinitely parallel... who knows?)

Also, one should not overlook an instance of a Turing halting problem and
indecidability situation that is quite familiar and relevant to this
group. Namely, the question of whether a given 'c' is in or out of the
M-set! Periodicity checking or direct mathematical computation of the
components of M (all described by various inequalities involving
polynomials p(c) and |p(c)|<=1) can determine more and more points as
belonging to M, and direct iteration more and more as being outside M, as
time goes on, but only in the infinite limit are all points in and all
points out identified.

Very interesting. The orbit on a P200 gave the impression of a beating heart.

I reproduce your par here with slight zoom in and color change so
I can see the edge a little better. I also toss out two others...these are
really chunky fractals! If we use passes=g we don't see correct valleys.

As for your remarks in the other thread...

I have the other day teased one of the computer science types I know
about the stopping problem applied to the brain. I suggested it might be
fear of such that drives some at the office to drink so much coffee!
(Would not want that up stairs computer to stop while contemplating
one of your Siegel disks.)  On the other hand,  I pointed out to him that
quantum effects might allow the brain to restart.

I can only hope that .....zzzzzzzzzzzz.... oops, got to be careful, almost

I agree. A few years ago I posted to sci.fractals an article titled

There is a socket library for DJGPP (Gnu C++ for DOS). It allows a DOS app
on a W95 system to access the Windows socket interface. Dunno how easy to
use/stable it is though.

If Fractint 20 is to have any of these really great features, it *must*
migrate to DJGPP or something similar. It is running out of room in its
640K, even with overlays, and even if you make it into "Fractdouble".

Simple case: one server thread, calculating one image; one client
(interface) thread. Interface thread starts calculation, then sleeps for 1
second or until a keypress (most cycles go to server, calculating) or
mouse input, redraws, sleeps again...

Using a thread package advanced enough to allow a thread to "sleep" with
no processor usage until there's input or a certain time, this would be a
piece of cake and the overhead would be minimal. Indeed, the drawing
overhead would be much less than in current Fractint.

First to address a concern about float precision being platform dependent.

The calculation engine can be platform independent easily enough, by a few
means.

If the server may run on a machine with no local client:

  * Server can conditionally compile by platform, using #ifdef and #define
    doublebits=80 (or 64, or 128) in different sections.

It may be easier to design if the server always runs with a client. Then
the client runs the server at startup, and tells it the platform's double
bit length and any other such parameters it needs. The client then
contains all platform-specific code.


Now the double client/server model: this involves one calculation server,
three interface clients for that server, one of which is also a client for
a window server.

* Calculation server: As above. Calculation server communicates two things:

Subject: (fractint) Fractal calculation server
Date: 10 Jan 1998 05:05:55 -0500 (EST)


What should the server calculate and send back?

The answer: Information enough to color the points, but not require
involving the server for simple enough coloring changes. (Palette, logmap
etc.) Only for more complex ones (changing to potential, distest, stalks,
decomp) would the server become involved.

How should that information be encoded?

The answer: As simply as possible.

Imagine the general fractal at this calculated, pre-render stage, to
contain one or more basins of attraction, each with one or two color
parameters, and some exceptional points.

Let each point be returned with a type; 0 is exceptional, 1 is a basin.
Each point also has a subtype; for type 1, this is a number identified
with the basin of attraction, 0 to n-1. For type 0, this depends on both the
formula and certain algorithms e.g. distance estimator. 0 is a generic
point used for uncalculated points; points not yet calculated when
rendering a partly done escape time; points not hit by an orbit type, IFS,
or L-system. Formulas can define additional types with positive integers;
so type 0 subtype 1 might be used by a Julia variant to display the
attractor or the critical points. Methods might define negative ones, so
type 0 subtype -1 might, in distance estimator method, mean filament.
As for basin points, type 1 subtype n, these have two other parameters,
m1 and m2, which are doubles between 0 and 1. These depend on the basin
and method. With distance estimator, m1 might be iter/maxiter or
distance/screen diagonal length. With continuous potential, m1 is the
potential. Decomp, in this case, would change m2 instead. Coloring could
use linear mappings a'la Fractal eXtreme from m1 to RGB space or from m2 to
RGB space, or planar mappings from m1xm2 to RGB space by allowing one to
select various points in a [0,1]x[0,1] square and pick shades for them,
the others being interpolated.

Julia set:

type=0 subtype=1 Trapped pixel
type=1 subtype=1 Pixel blew up (decomp about 0, color by iter, zmag,
                                potential to infinity, distest, etc.)
                                m1 depends: iter/maxiter, atan(zmag)*2/pi,
                                potential, distance etc; m2=decomp theta
                                about 0
type=1 subtype=2 Finite attractor  (decomp about attractor point; logmap
                                    inversely about attractor, etc.)

M-set:

type=1 subtype=1 Escaped pixel same as above
type=1 subtype=2 Set point, m1 depends on choice of zero, bof60, bof61...
                            m2 is period if caught by period checking else 0,
                            normalized using maxit.


Julia variant:

type 1 subtype 0 is A(infinity)
type 1 subtype 1...n attractor, based on attractor phase.


and so forth.

Subject: (fractint) Generalized Mandel/Julia types
Date: 10 Jan 1998 05:26:13 -0500 (EST)



A generalized Mandelbrot/Julia formula type should work as follows:

The formula specifies an iteration equation, together with initial
conditions, while also specifying *critical points* and attractors:

initial:
iteration variable z;
parameter c;
iterate:
sqr(z)+c;
critical:
0;
attractor:
infinity;

This should be interpreted at runtime as follows: Make an M-set by setting
z to 0 ("critical" and c to pixel, or a Julia setting c to a user
parameter and z to pixel; let the user perturb the M-set by choosing a
value that will be added to z. Iterate z^2+c; for the M-set use
periodicity checking and a user-chooseable bailout since infinity is an
attractor.

The attractor list should allow the keyword "infinity", any number, or any
expression in the parameter(s).
The critical list should allow any number, expression in the parameters,
or the keyword "guess".

Guess means that critical points will be sought by a modified Newton's
method dynamically at run-time, for the calculus-impaired to write these
formulas.

The run-time method is as follows:

Pick 100 random z clustered around 0, with fewer out to larger radii.
For each, iterate:
z->z-f(z)*epsilon/(f(z+epsilon)-f(z))
Note that this is just Newton's method replacing the f'(z) with the
approximation (f(z+epsilon)-f(z))/epsilon. Epsilon should be small, e.g.
1e-13. f(z) means to iterate the formula using a random choice of parameters.
This is repeated with a different random choice and critical points that
'wandered' are weeded out. (Those are beyond my ability to program a
computer to find :-) so they'd have to absolutely be included in the
critical: list manually!)



At run time, the user can choose Julia or Mandel. For Julia they can
choose the parameter values and run. For Mandel, they can choose any of
the critical points, choose a perturbation to add to z_0, and run.
Mandel types periodicity check. Julia types iterate all the (known)
critical points and say 100 random z to find all distinct attractors, and
build an attractor list, then the basins can be varicolored, or solid
colored by user choice.

For all, the basins can be further split by phase (one, some, or all), and
decomp should work around the attractor point detected.

Old formulas supported but fancy colorings depend on using IF and ENDIF
and outside=real and other clunky 19.6 style stuff :-), and then using a
single colormap with the single basin the engine believes exists.

Subject: (fractint) Determining if Two Points Hit The Same Attractor...or Siegel Disks Too!
Date: 10 Jan 1998 05:54:22 -0500 (EST)




If you iterate two z, how can you tell if they hit the same attractor?
If it's a cyclic attractor, the two z's might not be the same.


Simple trick: pick an upper cutoff maxit. Iterate z1 ... z_n
floor(maxit/2) times. Call the results b1 ... b_n.
With original z1 ... z_n again, iterate them again, until at most maxit
iterations in total (ceil(maxit/2) more iterations that is). After each
iteration, compare each z_k with all the b_i, i <> k. If it has reached
one of the b_i, remove z_k and b_k. i and k are the same attractor, out of
phase; the two b_i and b_k are redundant.
After the process is complete, the remaining b's, which can be renamed a1
through a_j, are points on j distinct attractors.

One problem remains: detecting the exceptional case of Siegel disks. A
point on a Siegel disk will eventually hit itself (using a "hit" function
returning true if two complex numbers differ by less than a tiny epsilon)
but if you have five points in a Siegel disk, chances are they will not
hit each other, only themselves, and you will obtain five would-be
"attractors" and large black areas in the image. This is Not Good.

To check for Siegel disks, after the above attractor detection, each of
the a_i is iterated along with say three random points in a triangle
about a_i and a small epsilon distance away; this is stopped when a_i has
hit itself.
A Siegel disk is assumed if: a_i has just hit itself, the three other
points all hit themselves, and they did not actually converge onto a_i. In
that case, we find the disk's centre as follows: starting from a_i,
iterate it once along with a smallish triangle of side r of surrounding
points. Note the distance traveled by each. The one that traveled the
shortest distance is closest to the disk's centre. Move a_i the distance r*1
in that direction, i.e. onto that point. Iterate the new a_i and a new
triangle (side r) and pick again the point closest to the center, move r*10
that way. Do one more iteration. Note as d1 the distance traveled by the
original a_i, d2 the subsequent a_i, and d3 this a_i. Choose
m=(2*d2-d3-d1)/9, compute d3/m, move a_i that far in the same direction.
Iterate it and note distance traveled. If nontrivial, repeat the whole
thing again. Repeat as necessary. At last, leave a_i fixed; it is the
Siegel disk center. Flag it as being such and not an attractor and record
the 'period'.

After doing this for all the a_k, eliminate redundant ones, ones differing
by less than an epsilon or so. These were in the same Siegel disk and
found the same centre.

Now during generation, check not only for points converging to any of the
a_i, but for a point that recurs with a period corresponding to (one of)
the Siegel disk(s), and for any such, use the distance from the original
pixel to the corresponding a_i Siegel center as m1 and the angle to a_i of
the original pixel as m2. (The m2 can be normalized readily enough but the
m1 for each/the disk will probably have to be normalized after the
generation, not during; for each Siegel disk keep track of an m1_max,
starts as 0 and after every pixel found to be in the Siegel disk, put
m1_max->max(m1_max,m1). Then go through the database of pixels and for all
the points in each disk, divide all the m1's by the appropriate disk's
m1_max to normalize them all to the interval [0,1].

Subject: (fractint) Storing Pars and Formulas, and Transmitting Them
Date: 10 Jan 1998 06:21:36 -0500 (EST)



Pars, formulas, maps... and now includes???

The simple way to do it is this:

The program creates subdirectories par, frm, gif, map when first run. All pars
are expected in the par dir or subdirs; frms; maps; gifs likewise.
A par file is specified with a name like: pgd.cubes.cubebrot_3 which means
to create the par in par/pgd/cubes/cubebrot_3.par, making directories as
necessary. Formulas and maps can be likewise organized, with DJGPP
supplying the long filename support on DOS/Win95. Names with dots on the
save screens or in parameters turn into appropriate subdirectories of the
appropriate directories, and extensions to the filenames are added
automatically.

Furthermore, everything tracks dependencies: a par file refers to a frm
file if necessary using the dot notation, same with map files. A par
always saves its map into a map file, asking the user to name it, if they
decline, naming it for the par file entry and putting foo.bar's baz
entry's colormap in maps/foo/bar/baz.map (the par in pars/foo/bar.par).
An old-style formula with includes lists these (themselves formulas) as
dependencies. A new-style formula has no iterational dependencies, but can
include an altcol: section.

altcol:
  m1: (expression in any variables left over after iteration is done that
      evaluates to a double; will be normalized after generation);
  m2: (same sort of thing);

All the usual methods, e.g. potential, can be used, whilst choosing altcol
for a basin will make it generate and use the m1 and m2 formulated in that
formula.

The altcol can be specified from a separate frm, which is a dependency.


The program shall allow the user to export a formula in an independent
format. An independent format chunk is a block of text of the sort

par: this.that.foo|bar {  ; Ends up in pars/this/that/foo.par entry 'bar'
  ;command lines follow
}

frm: diddly.doo.dah|funky {
  initialize:
    Iteration Variable z;
    Parameter c;
  ;etc.
}

map: bright.peacock {
  0 255 255 127
  linear
  0.2 255 128 224
  ;etc.
}

oldmap: dark.bluetwinkle {
  0 0 0
  0 0 12
  0 0 15
  0 0 17
  ; etc.
}

oldfrm: fuzzy1 {
  z=c=pixel:
  z=sqr(z)+c,
  lastsqr<=4
}

Any such sections may be included or omitted. An independent formula file
has frm: sections only, so all dependencies will resolve; an independent
par file has any frm's needed, and their dependencies, and any maps.

When loaded, it is parsed apart into sections, the sections are appropriately
saved in appropriate files (created if necessary) and, for frm, oldfrm,
and par, appropriate sections (overwritten or appended as warranted; they
may also be timestamped by creation time using a time: specifier, so new
versions supplant old and not vice versa).

GIFs or PNGs will save including a custom chunk containing appropriate
chunk headers and then the text of an independent-par for the image; on
load, everything extracts as needed.

This directory tree will be self managing; things that bloat can still be
trimmed by the user. The dot naming and the parallel directory tree allows
people to define name spaces for their pars or frms; nobody but me is
likely to use pgd.cube3|cube3_type2 for instance. There will no longer be
problems with pars or gifs not working after being obtained; nor with
having to extract frm: sections from parfiles, as this will be done for
you, and put in the appropriate place with the appropriate name too.
This may also cut down on bloated fractint.frm and fractint.pars, or
unmanageable messes of little formulas you don't know what are for. An
option might even be added to delete a given par or frm, together with any
of its dependencies then no longer depended-upon by anyone.

Subject: (fractint) Distance Estimator for any function
Date: 10 Jan 1998 06:25:47 -0500 (EST)




Herein is a generalization of the distance estimator method that, by
avoiding using the derivative f'(z), can be easily generalized for any
formula without having to write a new algorithm for it or know the derivative!


In the formula, distest=1/2*log(|z|)*sqrt(|z|/|z'|) where |z'| is the
derivative, replace |z'| with |(z-w)/e|, where w is set equal to z at the
first iteration plus a small value e. (w-z)/e is simply a quantity that
tends to z' as e tends to zero. For Julia types, z is as expected; for
Mandelbrot types, use 1/2*log(|c|)*sqrt(|c|/|c'|), c' approximated as
(w-c)/e, w starting out as c+e.

e must be chosen small (try 1.0e-13) for this to work well.

I tested it; it works. I did it on z^3+c.

There're plenty more Siegel disks... just check my post outlining an
algorithm for identifying a representative point for each finite attractor
and the center and a characteristic of each Siegel disk in an arbitrary
Julia set image of any kind, and detect convergence to any of the above
for each image pixel.

All of a sudden, I want to fiddle around with Lyapunov exponents...Julia
coloring by Lyapunov exponents, Mandelbrot by that of the critical

Say I wonder what the Lyapunov exponent does in a Siegel disk? Stays near
zero perhaps?

Arg. Not two new Liouvilles, two Siegels. :-)

Algebraic Siegels look a bit different from transcendental ones sometimes.
(Transcendental as in, pi-3, pi/4, e-2, e/3, 1/pi, 1/sqrt(pi), etc... Heck
even try (pi+e-5)^2.7! or exp(e-2)... gak. Inventing freaky transcendental
numbers rapidly produces prolific irrationals in prodigious quantities
with no practical value whatsoever. :-))

I gotta say, you definitely know your math, not just complex and
exponential, but even the Mandelmath from TBOF. :-)

Subject: (fractint) article in Dutch Newspaper
Date: 10 Jan 1998 17:40:05 +0100

I send this message for the Dutch speaking members of the list. I realise
this might offend some people, so for those who can't read Dutch (and for
those who can) I send a previously unpublished par-entry at the end of this
message.

(english summary: today's issue of the Volkskrant has an article about
Prof.dr. David Avnir who says that there are no real fractals in nature)

---- start of dutch message (it isn't very long)-----
In de Volkskrant van zaterdag 10 januari staat een artikel genaamd "De
mythe van de gebroken werkelijkheid". Het gaat over Prof.dr. David Avnir
die beweert dat het te ver gaat om de werkelijkheid door middel van fractal
geometrie te beschrijven. Op Internet
(http://www.volkskrant.nl/media/i25000006/p15000198.html) geeft Volkskrant
de volgende samenvatting:

Begin jaren tachtig vond Benoit Mandelbrot een wiskundige beschrijving voor
de Engelse kustlijn. Die houdt het midden tussen een lijn en een vlak.
Sindsdien ontwaren natuurwetenschappers overal zulke fractals. Maar
welbeschouwd zien ze voornamelijk hersenschimmen.

This probably falls more under the category of RTFM than RTBOF, but
I am curious about what I see when viewing these with the orbits window.
For the Siegel disk par, I can see it converge more or less smoothly to a
point, moving the cursor from about the center of the thing to  where I
expected to see a point it after reading a bit about Siegel disks. But for
the Liouville par, I get these pathological, broken looking sort of orbits,
the pieces being of different colors, particularly near the middle, and no
where can I make it converge to a point. What am I seeing when I look at
that broken, pulsating orbit. Is that what it's supposed to look like, or
is something wrong about my machine maybe? Also, is there  some unanswered
question about whether Siegel disks actually exist?
I've seen a picture in a book; but do some think they doubt their
existence.

Would one of you take a crack at explaining orbits in VERY lay terms to a
non-mathematician??? Also.....attractors (in the fractal sense).  Please do
NOT use formulas in your explanation, which are meaningless to me. I would
like to know what sort of image they generate.....for instance.....I know
when I pick "real" as an outside coloring option.....I get a ribbon-like
effect. Damiens new formulas remind me of strands and they are on the
outside of the mandelbrot set as I recall.....

Cindy;
Thanks for the info on the map files, I haven't used the "e" option much.
I've been working and saving my map files in "c" and "e" gives me some
new understanding of the RGB triplets I want to learn how to use.  Also
I've
been unable to load the Fractint.Doc file so I can print it out, it tells
me I
don't have enough memory which I know is not so, it's just not available.
One screen tells me to remove the "noems" line from my config.sys file and
not only is it not there but I don't like to mess with files like that on
these
new machines.  I hope someone out there can steer me in the right
direction.
I would also like to know how those RGB triplets work together and how
Fractint decides when and where to use them to color a pixel ?  If there is
some information somewhere on the web please let me know.
Thanks

Hi,
To make the docs go to Dos and go to your fractint dir. Type fractint makedoc.
You will have Fractint.doc. It is a very large file so be prepared when you
print it.
Worth while to have.
As far as the triplets go I would ask the list. Someone should be
able to answer. Put it just like you did here.

I prefer to put URLs on a line by themselves, just by themselves:

http://www.aloha.net/~shauna/

Avoids all kinds of problems, and helps (somewhat) with the problem
of those long URLs that get broken apart when mail clients do their
line wrapping ...

I'm back at Marquette after a month at home.  Unfortunately, I didn't
get the modem connected at my house, so I missed who the "big winner" in
the inaugural Fractal Art Contest was.

Also, my Fractint vs. XFractint comparison didn't go too well, as I
started just exploring with XFractint instead of timing it.  Oh well, I
guess that's what it's really for anyway.  I did find out, however, that
although Xfractint destroys normal Fractint in Julibrot mode, normal
Fractint beats X in user-defined formulas.  In normal Mandelbrots,
XFractint also has an edge, though not nearly as much as in the
Julibrots.  My assessment:  Use the one that runs on your favorite OS,
UNLESS you just want to run Julibrots, in which case you should
definitely get some version of Unix that runs X.

PS: My CD from Microsoft never came in, whixh means I'll have to change

I have been away for 5 days (probably not a bad thing- cameback to about 234
fractal- related  messages!)  I was reading
the book "Chaos Under Control    The Art and Science of
Complexity"  by David Peak and Michael Frame,  (W.H. Freeman
Co.  1994)  and there was a section on strange attractors. The book is
very interesting, aimed at a college-level non-mathematicianaudience.  The
section on fractal dimension was also reallyinteresting,  made me start seeing
everything folding all around
and understanding why people are seeing fractal forms in
nature- beyond my previous "hey! that looks like a fern."

I have already modified the developer version of Fractint. I would
like to hear most test results though. I have only heard from you and
Sylvie. Kerry wrote a note also, but I don't think he tested the new
code.

If the new encoder tests out, it will raise early release
possibilities. We might release a version 19.6 plus encoder or (with
more work) we could release the current developer version. The
problem with the latter approach is it is a big effort to release,
and it will slow efforts on the big changes such as true color.

Folks, I am more interested at this point in knowing that the new
simplgif works than knowing cases where the old one failed.
(Although of course it is good to know the new one works on images
that broke the old program!) The new code is at:

ftp://ftp.phoenix.net/pub/USERS/twegner/simplgif.zip

You can test it using existing images via:

simplgif existing.gif test.gif

The file test.gif should be a valid GIF87a file. (It won't have
fractal data unfortunately.) The file existing.gif does not have to
be (but can be) a multiple image GIF. Simplgif writes a large
temporary file in the current directory.

Thanks.

Yes, symmetry is likely the problem. It is up to the user to make
sure that the formula mathematically has the symmetry specified.
Fractint assumes in it's algorithms that the mathematical formula has
the symmetry thatbthe user askes for. There are times when Fractint
does the wrong thing if the formula is not really symmetrical. An
example is panning the screen. Fractint *could* be made to do
ka;eidoscope effects with symmetry, but this wasn't the idea befind
the symmetry options. The program uses symmetry purely as an
optimization.

For safety, symmetry should be turned off when using the
divide-and-conquor process.

I believe that was at Fractal-Art, and they collected _ALL_ links

Hi Fractintiers,

A local close out book store just went belly up. So I got an

includes CD, floppy and 3D glasses.  I also got a copy ($15)
which had these extras ripped off. Email me directly if you

Unusual apology for the SPAM, I'll make up for it with a

The 1821 and 1950 refer to Fractint versions 18.21 and 19.5,
respectively.  An older version of Fractint will have problems with a par
that uses capabilities only found in newer ones.

If you do not have the latest version, 19.6, it is available at:

http://spanky.triumf.ca/www/fractint/fractint.html

Spanky has a great deal of Fractint material in it, a starting index for
which is at:

 http://spanky.triumf.ca/

Good luck.

Sorry.  I would send you tim's_fract, but I repartitioned my HD

Hi.  It sounded like "Name the Artist" at Jack and Margaret
Valero's web site was about to go away so I went back to
have a look.  It's very interesting, quite a good choice of
different fractals from different people and well chosen.  My
favorite was actually  "Coral Reef" and I did not realize it was
by Sylvie Gallet- definitely art, but it was not at all geometric and
it was not in metallic colors.  I guess these are superficial qualities
and if you look at it more closely you can tell.  I think they were
overly humble in being a little apologetic about including their own
fractals in there.  I was am curious about the fractal "Faerie Stone"
how it was made and how the palette is so "liquidey."

I'm not offended...

But isn't this a well-known fact? I thought it "obvious" that self-similar
and other fractal-dimensional scaling phenomena in nature are only such
over a finite range of scales. There is after all a quantum limit to how
small a thing can be. The universe, too, is thought to be very large but
finite.

The fractal structure of tree bark starts at the cellscaleand ends at the
bark thickness scale, and so forth.

More complicated case: The server delegates portions of its job to other
servers as if it were itself a client. An example would be a server
receiving a request to calculate an 800x600 image and then breaking it into
three 800x200 images - it could do one and pass the other two on to other
servers. When those servers send back their work it would stitch the
results together a la Simplgif and squirt the whole lot back.

But will there be enough servers to go round?

You want to read a short story by Christopher Cherniak titled "The Riddle
of the Univese and Its Solution". It appears in Hofstadter and Dennet's
_The Mind's I_. In it a certain piece of information is discovered which
brings on something that becomes known as "Riddle Coma" - the first victim
dies of starvation.

"The outbreak of a Riddle coma epidemic in conenction with a
computer-assitsted theorem-proving project could be explained; if someone
discovered the Riddle in his head, he should lapse into coma before he
could communicate it to anyone. The question arose of whether the Riddle
had in fact been discovered earlier by hand and then immediately lost. ...
At present, at least ten suspect cases have been discovered, the earliest
almost 100 years ago."

The truth is that you don't need any mathematical knowledge to fool
with formulas, just enough knowledge of the formula language to write
formulas that are syntactically correct. The best way to do this is
modify existing formulas.

When I give demonstrations to high school math classes, I have
fun writing bizarre formulas bristling with important-sounding
transcendental functions like sinh(z) or exp(z). You can just about
always get an interesting fractal in this way. I don't know about
molecular structure, but you can certainly model fractint formulas
after famous equations. I'm not sure the results are any better than
just typing in some hocus pocus though <g!>

Here's one I just wrote down with zero mathematical insight. I
challenge the list to come up with some nice PARs using this.

Tim's_fract { ; Example of a more or less random formula
  z = Pixel:
   ; I have no clue what the point of this formula is
   ; it came straight from my subconscious <g!>
  z = (sinh(z*z + log(z)))/(z*z + 2)
  |z| <= 16
  }

Let me also say that while non-mathematical artists can show
brilliant creativity with formulas, understanding math can add
another dimension to fractal art. Sylvie Gallet, for one, is a master
at applying her knowledge of mathematics to the art of building
formulas that create fascinating fractals.

On behalf of all bgOutlook (and probably bgExchange and Outlook Express)
users, I can say that it recognizes URLs if they have a space before them,
a space after them, and are not split over two lines :->

Like this: http://altavista.digital.com - easy really.

If you want you could do <URL: http://altavista.digital.com > , as long as
there is a space after the end of the URL.

That's just it... the compuserve software isn't thinking at all; it
just puts printed-quotable on every message it sends.  At least, that
is what the compuserve technical support people seem to be saying.

Yes, other people have been sending a few messages that are this way.
However, although I didn't do an exhaustive search of every message
ever posted to fractint, I just looked over the ones I'd gotten
recently.  Of those, the ones with content-transfer-encoding of
printed-quotable were from:

    Lee Skinner <[e-mail]>
    Les St Clair <[e-mail]>
    Sylvie Gallet <[e-mail]>
    [e-mail] (Guy Marson)
    "Steve Jenks" <[e-mail]>

With the two non-compuserve addresses accounting for only 4 messages
out of 42.  Of those 4 messages, one originates from a place on the
globe where iso-8859 is the natural encoding (i.e. europe) and the
others are in printed-quotable because of the way Steve Jenks appears
to have configured his email program.  (Microsoft Outlook Express)

There is one strange one however.  Clamcake forwarded one of my
email (when the server was messed up) and it got the =3D sickness
without Compuserve involvement.  Clamcake is on aol.  See

Excuse me, but you are incorrect.

Have you ever used, or do you use, the "QuickRes" utility that I
mentioned???

I can go from the following modes back and forth in only about a second
with no reboot what-so-ever:

    640 x  480  @  256 color (8-bit)
    800 x  600  @  256 color (8-bit)
   1024 x  768  @  256 color (8-bit)
   1280 x 1024  @  256 color (8-bit)

    640 x  480  @  HiColor (16-bit)
    800 x  600  @  HiColor (16-bit)
   1024 x  768  @  HiColor (16-bit)
   1280 x 1024  @  HiColor (16-bit)

    640 x  480  @  TrueColor (32-bit)

Besides, "Bagpuss" only mentioned changing resolutions (the number of
pixels in the image horizontally and vertically).  Nothing was mentioned
about the amount of colors available (even though it may be done without
reboot).

Resolution is the amount of definition and clarity in an image.  The dot
pitch of a CRT display monitor affects resolution.  However, resolution
is usually measured in terms of the number of pixels ("picture elements"
or screen "dots") per square inch.  By varying the display device driver
the operating system is using, a user can vary the resolution of the
monitor by changing the number of lines on the screen and thereby
altering the number of pixels.  For example, one could reset a Windows
setup to select a driver that provides an 800 (horizontal) by 600
(vertical) line display.

The upper limit of resolution for most PC monitors is about 72 to 100
pixels per inch. As a comparison, most PC printers offer 300 to 600 dpi
(dots per inch) resolution.

Yes, and it required me to reboot if I changed the pixel depth.

Must be something unique with your system setup.  I have been using is
for around two years now without problems.  And all of my friends and
work associates that use it have never had any problems either.  In
fact, there are thousands of individuals that use this.

Maybe you should try downloading it again from:

   http://www.microsoft.com/windows/windows95/info/powertoys.htm

And then give it another try.

I'm using P166 Win95 version 4.00.950 B and not the greatest
amount of video RAM. I'm not using QuickRes, but I can
change among these without rebooting

    640 x  480  @  256 color (8-bit)
    800 x  600  @  256 color (8-bit)
   1024 x  768  @  256 color (8-bit)
   1152 x  864  @  256 color (8-bit)

    640 x  480  @  HiColor (16-bit)
    800 x  600  @  HiColor (16-bit)

But if I want higher resolution I can get

   1280 x 1024  @  16 color
Going to this one I must reboot.

I think there is a Win 95 version dependency here.  An older
version on a P200 with bigger monitor and more RAM had
to boot as I recall. I'll check it again later.

I believe that the reboot requirement depends on your video card.
So as I said before, even though you have the MS "power toy", you
still may be required to reboot when changing video parameters.

This could be possible, or it might have to do with the OS release
level, or drivers and release level, or some combination of these.

Well, not quite what you said before.  But, at least you have revised
your original "will still have to reboot" to "may be required to
reboot".

I'm slowly catching up on reading hundreds and hundreds of e-mail
messages. Read this one today that was posted to the list server on New
Year's Day:

Question: Is the equation z=cos(z)/z+pixel correct? If so then c=z=pixel
is not needed & should be rewritten as z=pixel. If, on the other hand,
c=z=pixel is correct, why is there no "c" in the equation? In other
words, is "c" being used or not?

Taking Bill Rossi's recommendation of this past Monday, how about...
z=fn1(z*z)/z+c or z=fn1(z*z)+c/z+pixel or fn1(z*z)+c/z or
fn1(z*z)/z+c+pixel or, or, or, etc. etc. etc.

Just putting in my two pfennigs.

Hey....I have powertoys too!!!  And I'm a computer dummy......they work
great....I keep the screen resolution do-dad in my tray ....get it!!!
There are some more cute tricks in the package too....

This is only slightly off topic since Sylvie once pointed out to me that
her Winfract color cycled....so does mine in 256 color mode...which you
can
re-set with the powertoys thingummy......frankly its easier to run
fractint
under windows in dos.....mostly the screen res thingy is good to look at
your web pages in two resolutions....800 x 600 and 640 x 480....or 1200 x

I just turned it off. I was trying to debug a problem sending attached
files
to people on AOL, and that's what my ISP suggested. It didn't work, but I
forgot to reset it. So that's one less to puzzle over.  SJ

You can solve this potential problem by enclosing the URL in <URL: >, as in
<URL: http://www.yahoo.com/>.  The <URL: > enclosure has been proposed as a
way to embed URLs safely within other text files and have them be easily
recognized and extracted by programs.

No, please don't do this.  I'm using bgOutlook and it includes the final
">" as part of the URL :-(

Maybe put a space before the end of the URL and the ">".

Rich,

 - This is only true if you don't change the depth of the pixels.  So if
 - you switch from 1280x1024 256 colors to 1024x768 16-bit color, you
 - will still have to reboot.

Not true.  You can switch color depths, too.  The problem is, most
graphics
software only checks the color depth when it is first started, so if you
change color depths, the software isn't smart enough to check and adapt.
Closing and re-opening such apps generally is enough to get them to work,
and closing all graphics apps and re-opening them is a far cry from a full
reboot.

I have personally used QuickRes on many different graphics cards, and it
never required a reboot on any of them.  However, I *have* used the
"screen
managers" that ship with most brand-name graphics cards; these managers
also provide a resolution-switching option, but they generally *do*
require
a reboot.  I typically disable video card screen managers now, and just
use
QuickRes. :)

Bagpuss,

 - hmm, I DO care if the render time goes up...
 - Win95 has a horiffic processor overhead, and while this is
 - fine on a fast machine (most programs dont use very much
 - processing power) for processor intensive work (like fractal
 - and 3d rendering) DOS is better by far - up to 2.5 times
 - faster on my machine.

Then your machine is configured incorrectly.  Properly set up, FractInt
running in a DOS box under Windows 95 is only 2% slower.  This has been
covered before on this list.

Hi Kerry,

I'm putting Paul Carlson's in a file which I update whenever he gives
us a new formula.
http://home.san.rr.com/jayrhill/CARLSON.PAR
Ed Avis: how does this work for you? Put the URL on a separate line?
BTW, I have about 10MB of archive of this list from which pars and frms
could be extracted.

Question again (I asked this a week ago). What do all you all
think would be the right way to do this? One big frm and one
big par for each of 1996, 1997. Then small ones this year?
What should be included? Enough of the header and test to
ID it and document the formula? Then there is the problem
of cross referencing between them. frm will need a reference
to the names of the sample pars. Anything else?

Jay

Jay,

 - BTW, I have about 10MB of archive of this list from which pars and frms
 - could be extracted.

10M!  I thought I had all the messages, but I've got less than 7M of
material.  (Then again, I didn't get that 2.5M file somebody posted to the
list, either...)

A big PAR for previous years should be fine.  If the creators did not
include their name in the PAR comments, edit the PAR to include the name.
The date of posting would also be nice, but not critical.

All FRMs should be in a separate file, organized similarly: author's name
included, possibly date of posting.

Wasn't someone also collecting URLs posted to this list?  Or was that the
Fractal-Art list instead?

Thanks to Jay for purposely piling up Paul's proxy postings.  :-)

What I did, to make his file a legal par, was to wrap comment { and }
around the text part of the pars.  Perhaps this could be incorporated into
the grand par/frm extraction project.

Just posted in alt.binaries.pictures.fractals is a .jpg image of a fractal
in a very nice astronomical setting. The image itself is well worth
seeing,
IMO, titled eggsplosion, Karl Boehnker.

If Fractint is able to generate something something similar, would someone
kindly post how? I have seen two similar (only in a sense, one was a
couple
of spirals in an astronomical setting) pieces before...(BTW, I have also
emailed Mr. Boehnker concerning this...)

After hitting "a", the _only_ thing I have ever been able to generate is a
star field and have never been able to do anything with it. Including when
starting off with a fractal before hitting "a"...

Beginning after the recent contest, I have been collecting most pars and
frms that
have come through to my mailbox.  My save format is  something like this:

; Date
; From

; or Comment { ... } if there is a comment  or part of a comment I want to
save

formulas or image parameters

But I change as I go - lately, I've just been making a  single comment out
of date,
from, and any narrative I want to save.

Up to December 31, 1997, I saved them in Dec97.par and Dec97.frm.  All the
pars
are  cleaned up and all draw.  For many of the images, I've modified the
comment
lines in the parameter sets by adding the time it takes to draw on my
equipment.
If there were formulas without pars to call them, I have only spotchecked.
 Some of
the formulas, like the vector and dmj-pub formulas, I've saved in their own
frm
files, again with spotchecking on how they run.

There's an exception to haveing all the par/frm sets!  Somewhere along the
line, I
lost track of the formula, xmasseahorse.  Maybe somebody could repost that
one to
me at my personal mailbox.

Now, I'm working on Jan98.par and Jan98.frm.

I have not taken the time to cross reference the example pars to the
formulas
because the formula names appear in the pars and can be searched out with
PFE32 or
by visual scanning in an editor.  This should not be much of a problem if I
stay
with the month-sized files.

Dec97.par is about 58K and Dec97.frm is about 20K in size.

I don't have much experience in posting except as attachments, which I
understand
some of you have difficulty with.  If anyone wants one or both of the
above
collections, the vector frms or the djm-pub frms, let me know, tell me how
you want
them posted to you, and I'll give it a try.  If the number of people
wanting them
is small, it will probably be best for me to send such postings to your
personal
mailboxes.

I'm not committing to anything for the future!  I have to travel in my
work, and
may even eventually decide to withdraw from this list because of the volume
of
traffic -- 60 to 80 messages in one 24-hour period is a bit much!  Sure
have been
learning a lot, though and getting many good images and formulas.  So, I'll
stick
with it as long as I can.

This is very much what I had in mind when I suggested the idea, after all
you don't get any speed increase with just one server at work :-)

If everyone on this list (who I presume have internet access) ran a
Fractint server on their machine, and shared with the other readers, we
could get some seriously fast fractalling done.  Especially with the
difference in timezones meaning many machines are idle when others are
being used for fractals.

If anyone has a spare supercomputer, they could run a Fractint server on
that as well...

I would suggest we send "chunks" of say 50x50 pixels via UDP, rather than
the whole image at once.  Of course if the fractal being calculated was
very slow and complex, it might be good to have smaller chunks than 50x50.

QuadcolorMand { ; Parametrized quartic Mandelbrot sets, colored based on both
                ; critical points. p1 is alpha parameter. Use outside=real,
                ; float=y, periodicity=n, maxiter>=256, and logmap=0.
                ; To get logmaplike effect, choose real p2 equal to lowest iteration
                ; and real p3 to nonzero, bigger means more colors are pushed to
                ; lower iterations. Use imag(p2) = 0.001 or similarly tiny.
                ; Color 0 is for all critical points trapped.
                ; Colors 1-66, 67-129, 130-192, and 193-255 are separate ranges.
                ; Use first for outside, second thru fourth for one
                ; critical point escapes, one trapped.
                ; Very beautiful.

Hi,

        I was wondering if there is an easy way (easier than by hand) to
find the values of variables in a formula. Perhaps future versions of
fractint could include a debug formula option which would dump values over
succesive iterations to text files.


                                                                        :) Ben
Ben Leighton, [e-mail]

        All my statements are questions?

Each server should do a 'scan' to determine the parts of the image it is
assigned which are slow. The sizes of next generation chunks could be
determined for each portion using a quad division algorithm.

No. In my earlier post I meant that neither the "Name the Artist"
or "But is it Art" pages appear to have stimulated much participation.
(Posts like yours herein are what I had originally hoped to elicit.)
I interpret this as a general lack of interest so have abandoned any

removing either page in the near future.

For the record, I did not choose these fractals. Each artist
submitted their personal choice. They do offer an interesting
fractal spectrum, don't they?

Personally, I don't think they are at all superficial. Sylvie's piece
offers wonderfully subtle and soft colouration and I believe that
to be the subject of the work.

You are very kind. But these artists have spent a great deal of time
studying and perfecting their work. In contrast, Margaret and I have
been at this for half a year and are new kids on the block. Perhaps
we have between 200-250 fractal hours between us. It would be
presumptuous of us to assume similar expertise.

I assure you this is not a case of false modesty. We think some of
our work is very good but most of it is, well... okay. We are
accustomed to the complete subject, lighting and compositional
control of black and white art photography as afforded by
darkroom and studio. Contrarily, our command of fractal
imagery remains maddeningly elusive.

If we continue we will undoubtably become quite skilled in time
but, unfortunately, that time is not today.

>I was am curious about the fractal "Faerie Stone"
>how it was made and how the palette is so "liquidey."
Strange and wonderous things may come to pass within the
shadowy domains of faerie...
Seriously, Margaret used Stephen Ferguson's wonderful Flarium
program for this one. The hint of the fairy figure appeared
quite early and she experimented with colouring and
filtration to bring it out. We both thought it should
be more jewel-like but were unable to achieve the desired
luminosity or translucence solely within Flarium. We resorted
to a secret weapon- PhotoShop. I don't recall all the details
but I think I eliminated some background information, applied a
very small amount of glow effect and tweaked the contrast
and brightness. We no longer have the original Flarium data
file so can't advise the formula, filtration or colouring
method. Sorry.

There is a limit to how far we can predefine things in our arguments.
I imagine the good Doctor was confining his remarks to the macro
world.

Still, I wonder about his premise. Most multicellular life forms
are incredibly repetitive in somatic structure. As fractals excel
at containing repetitive information, I wonder if somewhere along
the road evolution has not hit upon this as a storage mechanism
for genetic information. Apparently, a substantial amount of DNA
information appears to be random noise. At least, we don't seem
to understand its presence. I have no basis for this speculation;
I just wonder at times.

Yes, that would be a good idea.  It seems to me that a lot of this may just
be idle speculation, but it's interesting anyway, so why not:

For each square, calculate the top left-hand corner.  If it takes longer
than say ten seconds, and depending on how "busy" other servers are, then
send off the other three pieces to be calculated separately.  Otherwise,
calculate them ourselves.

How do we calculate the top left-hand corner?  Easy! Just apply the
algorithm above, recursively!  Of course at one point we have got to stop
and actually do some calculation, the point at which we do this could be
determined according to the complexity of the formula.

Anyone else ever involved in the RSA decryption process? To test the
security of public-key encrypting at a given number of bits, they hold a
contest where groups attempt to generate the right key with a basically
brute-force approach. Software that lets this task be easily distribuited
among anything running UNIX is availible, and so your organization
installs Linux on its washing machines and renices the process down to
minimum priority; even the processing power of a washing machine adds up
over time...

Anyway, we've found that it's important that the process be able to run
from a command line since XWindows is less than perfectly stable; but
once you set that up, you find that bored employees at Sun and SGI set up
their servers to run it in the evenings... no shortage at all.

Lee,

 - Passes=1 is the only non-guessing algorithm.

The online help indicates that passes=2 generates the same image as
passes=1, just doing a lower-res pass first.  Is the second pass a guessing
pass?  I have been using passes=2 quite a bit; if it guesses on its second
pass, I will need to go back and re-generate quite a few images.

I don't understand.
1) DOS resolution mode are independent from Windows mode.
2) With Windows 95, if you use the Quickres utility, you can change screen
resolution on the fly, without restarting the machine.

It's all listed in the Fractint Revision History.
This is in appendix G of "fractint.doc" and also in the "new features in

I'm just wondering if there might be some more sophisticated way of
breaking the task down that will distribute the server workload more
fairly. I thought this because the approaches that divide the image up into
chunks ignores any defined symmetries of the fractal. I know that
multitasking makes up for much of the difference, but we may still be
calculating up to four times as much as we need to. This could be resolved
by having the server check for symmetries in the (sub)image it's given to
compute, and delegating tasks accordingly but I still wonder.

I thought perhaps instead of contiguous blocks an interlaced approach could
be used, so that the points being calculated by each server are spread
evenly over the entire image. Kind of subidividing the task upwards instead
of down. That's just off the top of my head and not really what I'm getting
at.

A more sophisticated multitasking model would require more sophisticated
protocols: the present idea could be done simply by passing pars/formulas
and gifs back and forth, while something else may need to carry information
on orbits back and forth. "I'm up to here... it still needs this done..."

Someone more familiar with the Fractint engine may be able to provide more
constructive suggestions along these lines than myself.

I have been playing around with the formulas fora little
while now, enough to see that you can
throw in a "cos(z)" or whatever without
having an idea what the function is or what it
might look like, and it is a lot of  fun to do that.
I notice some things like if you choose tan as the
function, it tends to have a certain look and I can
kind of see that without understanding why that
might be, but I would actually like to understand
the math of it better because it is interesting.  Sometimes
I throw in a bunch of extra terms expecting it to give
a more complex, or maybe I should say "complicated"
picture, and it will end up being a circle or a blank screen,
and sometimes I can see why. (But usually not!)
        I have been fooling around with the FGZ-Julia
formulas by Michael Wareman posted
to this list by Wizzle and I found one
that had sort of a 3-way radial symmetry in all the
little meeting points and I was wondering how you would
write a formula that had 4-way or 5-way symmetry at those
points and it turned out that subsequent formulas in the series
had exactly that.  The weird thing is that the only thing that is
different between them is the value of the constant c.  I would
have thought that to change a 3-pointed star to a 5-pointed
star you would have to change the number of variables or
add a function or something, not just change a constant.
I'm curious about what the people who understand all
this can envision when they see a formula.

Hi Morgan,

Formulas first: I think that just about every publicly available Fractint=

collection by George Martin. Get it from:

As for Fractint par files from the GraphDev library at CompuServe,
some are already available on the individual web sites of artists such as=

Brian E. Jones and Sylvie Gallet. My collection, too, is available from:
http://ourworld.compuserve.com/homepages/Les_StClair/
(shameless plug :-)

The problem with the bulk of the CS archive (in my opinion) is that we do=

not have the right to re-publish these files without the consent of their=

authors. If there is enough interest, I would be willing to contact a few=

of my favourite fractallers and seek permission to make their files
available at my own site (space permitting), or though any other =

interested party.

cheers, Les

The article can be found in the 2 January 1998 issue of Science, "Is the
Geometry of Nature Fractal?" by David Avnir, Ofer Biham, Daniel Lidar, Ofer
Malcai.

As has been noted by others, Avnir's group's main argument is that natural
phenomena are only self-similar over a finite range of scales (orders of
magnitude), whereas a mathematical fractal, and therefor the true definition of
fractal, means that a structure is self-similar over an infinite range of
scales.

This was known to Sir Mandelbrot; I do not think he claims that natural
processes can be exactly modeled with scaling power laws, but that the concepts
of fractal geometry do well to approximate natural systems, in simpler terms
than a Euclidean approximation.  Avnir et. al. recognizes this advantage in the
article.

Personally, I am excited for the work done by Avnir and assoc., because it may
help direct attention to the fact that natural systems do not scale infinitely,
they seem (to me) to 'fuzz' into another or other systems, which are well
described by a different set of power laws, and so on.  Each 'system' - they are
not really separate systems but subsystems imbedded in the Big System - has a
set of scales or scale at which they are best described by a certain power
law... could this be described as an attractor of a sort?  And the big question:
how does one connect two 'separate but consecutive' sysems through their power
laws?  In my mind there is an analogy here as if one were trying to determine
the position and orientation of a mini-Mset by the pattern of filaments closely
surrounding it.... but that's just my mind, and though this may be on topic,
it's still unbacked blathering, so I'll cease.

Trees, Jason

Subject: (fractint) Julia Sets, Orbits and Siegel disks
Date: 12 Jan 1998 13:08:57 -0800

   Julia Sets, Orbits and Siegel disks.
       (c) Jay R. Hill, 1998

They say the Mandelbrot set is a map showing us the collection of
possible Julia sets. So let us take advantage of this as we use
Fractint to explore both. In this memo, I shall explore and
explain some of the hard to understand topics found in such
books as are found on the coffee tables of fractal junkies. Many
of us have these books and enjoy the images. But when it comes to
the text, well that, we say to ourselves, is there to impress the
guests.  And we resolve to, some day real soon now, read it and
figure it out.  In the mean while, we just continue to subscribe
to sci.fractals and Fractint email lists. And, if they ever get
back on topic, maybe it all will become clear.   :-)

We are interested in iteration formula, iterating a complex number,
z, using some function of z and another parameter, c.

(1)  z = f(z, c).

When f in eqn 1 is z^2+c, we get the Julia set and Mandelbrot set,
depending on whether we fix the initial z or fix c for a picture.
There are several formula in this memo which will be useful to help
quantify some of the concepts we shall explore.  Special effects
will require careful evaluation of certain parameters using these
formula for our images to come out right.

The iteration or orbit of z, which depends on c, can behave in
one of four ways:

  1) repeat in a cycle,
  2) converge to a cycle,
  3) diverge to infinity, or
  4) wander in a wigglely curve.

Save this whole file as a par file, run Fractint and choose the
Mandelbrot_set image (below). Use a high resolution setting with
256 colors. When it finishes computing, press the space bar and
then the 'o' key. This will show the orbits of eqn 1 in the lower
right corner where the value of c is chosen by moving the '+'
symbol around on the Mandelbrot set.

Mandelbrot_set   { ; (C) Jay Hill, 1998
                   ; Turn on orbits and watch...
  reset=1960 type=mandel center-mag=-0.5/0/0.4 params=0/0 float=y
  maxiter=1280 inside=bof60 outside=0
  colors=000000<13>www<30>CCCAAAAAA<45>lllmmmmmmmmm<155>www000000
  }

Try moving the '+' symbol around and explore the shape of the orbit.
Move it to the central dark part in the central part of the cardioid.
At this point, c=0 and the orbit is of type 1), a single dot, z=0.
It is periodic with a period of 1.

Now move it over to almost the center of the big circle left of the
cardioid, here c=-1 and the orbit is two dots, z=-1, 0. The orbit
is again type 1) with period 2.  As the '+' moved from the cardioid
into the circular bud, the orbit changed from converging to a single
point to converging to two points. The orbit went from period 1 to
period 2, the transition taking place as c crossed the boundary -.75.

Notice that the convergent points, a, also changed, depending on c.
It can be shown that these convergent points are

(2)   a1 = +0.5 - sqrt(+0.25-c);  c in the cardioid

      a21 = -0.5 + sqrt(-0.75-c); c in the circle.
      a22 = -0.5 - sqrt(-0.75-c);

How can we tell, without iterating eqn 1, which component (cardioids
and circular buds are called components) c is in?  I give here a
simple formula with which you can test this.

Let s = [abs(c)]^2.  Then c is in the cardioid if

(3)    (256s - 96)s + 32 Real(c) <= 3.

Or c is in the circle if

(4)    16s + 32 Real(c) + 16 <= 1.

Now let's move the '+' off the real line up toward the period 3 bud
sitting on top of the cardioid.  Move from in the cardioid, but just
below the bud, across edge of the cardioid and into the bud. Observe
the orbit pattern develop into a three pointed star and separate into
three separate convergent areas. These three areas collapse onto three
points, call these, a31, a32, a33, when we move the center of
the bud.

Press space bar to return to Julia set display (lower right corner)
and repeat. Observe the shapes of the Julia set. See a single curve
when the '+' is in the cardioid, a row of shapes when in the circle
left of the cardioid. With c in the period 3 bud above the cardioid,
we see a flower shape featuring triples patterns with petals joining
in threes.  There is a relationship between the orbits (three groups)
and these petals. Notice that the orbits converged into the same
areas as three of the petals occupy.

The Julia set display shows points in the z plane for which the orbit
does not diverge. Consider an initial test point z0 which is in one
of the Julia set petals. Its orbit spirals around converging to one,
say, a31, at the center of a petal. Every point in the orbit can be
considered an initial z, just like z0, each with an orbit converging
to a31. Therefore, every one of these orbit points must also be inside
a petal.  Notice there are more than three petals in this Julia set.
All contain z which after a few iterations jump into one of the
first three petals joining the others in their convergent path.

It is most interesting to explore, with the '+', the cardioid and
circle edges. For it is here that the orbits become very intricate
and tend to fill their Julia set petals. In fact, it is right on the
very edge that we get type 4) orbits (which wander in a wigglely
curve).  These orbits do not converge to one of a set of points,
but remain 'indifferent', being neither 'repelling' nor 'attractive'.
And their Julia set petals, called Siegel disks, are very different.

Siegel_Gold      { ; (C) Jay Hill, 1998
                  ; Turn on orbits and watch...
  reset=1960 type=julia passes=1
  center-mag=0/0/0.85
  params=0.3253814503389081470/0.0535920759383226465
  float=y maxiter=150000 inside=bof60 outside=0
  colors=000000<13>www<30>CCCAAAAAA<45>lllmmmmmmmmm<155>www000000
  savename=Siegel_G
  }

An example is Siegel_Gold. Start the display in Fractint, turning
on the orbits right away (press 'o'). Notice the orbit seems to
almost fill a region which, as the Julia set is drawn, lies in one
of the petals.  The orbits do not converge to points, but rather,
cycle endlessly around the convergent points in 'circular' orbits.
Each iteration moving around the convergent point by an angle, the
same angle as the interior angle, not a surprise.  Also observe
the attachment points of the petals are not sharp. This is the
Siegel disk, a nicely connected shape, distinctly different from
the other Julia sets where regions join at points.

When the picture is complete, press space bar to see the Mandelbrot
set. Now press the space bar again and the '+' will be located at c,
corresponding the Julia set.

This value of c is right on the boundary of the cardioid but does
not touch one of the attached buds. Buds are attached at points
for which the 'interior' angle is a rational multiple of 2*pi.  The
Siegel_Gold c was found using the golden ratio to get an irrational
angle and the resulting Siegel disks.  Any irrational interior angle
will get Siegel disks when applied to any Mandelbrot set component.

Irrational angles created from roots of quadratic equations (having
the form r = (L + sqrt(M))/N, where L, M, N are integers) are of
interest since they lend themselves to certain proofs about Siegel
disks.  As far as we are concerned, when we want to make interesting
fractal pictures, any irrational or transcendental angle will do.  For
example, the arc tangent function produces these angles. Just take
atan(M/N), where M and N are integers.  A convenient way to get these
integers and at the same time control the shape of the Siegel disk
is to choose coordinates right off the edge of the Mandelbrot set in
Fractint.

Zoom into an interesting region near the edge of the cardioid
(elephant valley, c=-.25), or the circle (sea horse valley, c=-.75,
scepter valley, c=-1.25). Note the center coordinates, c0, (press z,
then F6 to see the values). I have created a small MSDOS program
which normalizes these coordinates to the nearest edge of the
cardioid or circle. The new calculated c will give a Siegel disk.

Here is the pseudo-code for the program, SIEGEL.EXE.
  for c in cardioid:
  c0=complex(x, y);
  w0 = (1 - sqrt(1-4*c0))/2;
  z = log(2*w0);
  w=.5*exp(complex(0.,imag(z)));
  c = w*(1-w);
  convergence point:
  a =+0.5-sqrt( 0.25-c);

  for c in big bud:
  c0=complex(x, y);
  w0 = 1 + c0;
  z = log(4*w0);
  c = -1+.25*exp(complex(0.,imag(z)));
  convergence points:
  a = -0.5+-sqrt(-0.75-c)

And I have a proof but it is too big to write in the margin <g!>

Passes=2 is absolutely guaranteed to be identical to to passes=1.
Fractint goes in 1 pass mode, but writes every other line, but also
writes the line below with the same line for appearances. On the
second pass, the even lines are corrected.

The only exceptions I can think of:

1. If you are using a formula that does not properly initialize
variables (whether a buggy built-in formula or an ill-formed parser
formula) then the color of a pixel would depend on the value the
uninitialized variable had previously. In this case, 2-pass would be
different because the pixels are do0ne in a different order.

2. If random numbers are used, calculating the pixels in a different
order chganges the result.

My carefully qualified statement becomes: for all fractal algorithms
where the color of a pixel is independent of the previous pixel and
independent of the order of pixels (eg - no random numbers) then 2
pass is identical to 1-pass.

Maybe your counterexample used random numbers. That would do it!

Unfortunately, many of my pictures use the symmetry even when it's not there
mathematically.  It's also frustrating that d and c worked with these formulas
on my old 486dx33 and now won't work on my Pentium II 266.

Thanks anyway.  Still the best program going!

I concur with all of the above.  As I remember, I was running some pars
that had some fuzzy artifacts along the left edge of the image. The par
specified passes=3D2.  When I tried passes=3D1, the picture was different=
=2E It
could very well have been (and probably was) due to uninitialized
variables.

Kathy...

How did you figure out what values to enter?? This is exactly what I want
to to do a formula....change it from pentagonalish to 6 or 7 pointed or 8
or 9 points. I tried changing the constant in the formula I'm fiddling with
and didn't notice any change....and you picked such off the wall numbers.
Replacing sqr with tan or atan or atanh in my particular formula yielded 3
pointyness......maybe I can throw in a 2 or something.

Hi Wizzle and Kathy,

Minor correction of the post, it was Tim that had words of wisdom...
Anyway, wizzle, read my article, it explains all  :-)
Well not all, but the formula are labeled Julia sets which they are.
As many points as you wish are there. It is a Julia set. That
means there is a Mandelbrot set in there somewhere which is
a road map to this Julia set, showing us the very constants
you are looking for.  Take another look at Paul Derbyshire's
Jan 2 lesson on Calculus.

The Mandelbrot set for this equation needs the roots of a quartic,
if my math is right. Hmmm... Maybe you will not want to follow
that path. But there is a graphical solution to this, using Fractint.
I'll explain it some time.

After some experimenting (which I'm not through with) I have found
some solutions for you. Try this function as a Mandelbrot map of this
Julia set.

frm:FGZ-M    { ; Jay Hill
   c = pixel,
   z=-sqrt(-c): ; approximate critical point
   z = z * z + c;
   z = (3 * z * z) / (z + 3) + c,
   |z| <= 36
  }

frm:FGZ-J   { ; Jay Hill
   ; p1 is the Julia set parameter
   z = pixel, c = p1:
   z = z * z + c;
   z = (3 * z * z) / (z + 3) + c,
   |z| <= 36
  }

Use the FGZ-M set, which is only approximate, to determine values
for c to use in the Julia set. Then run FGZ-J to see the Julia set.
Put the c in the p1 parameters. Pan around to see the patterns of
interest.  I have increased the bailout to check that we are not missing
anything.

Here are some sample values of c for branching patterns:

branches    real/imag of c
3     -0.19907435765/0.673367053
4    0.216404468/0.572864145

Hi.

     This list is incredibly active. I just subscribed myself to the list and
within a few minutes...I get mail faster than I can read it.

     Isn't there any way to have digests for this list?

     I love fractals, but I'm signing off this list for now. So please send
in your answers to my address ([e-mail]).

Thanks.

Date: 13 Jan 1998 04:10:14 EST

Hi everybody!
I'm new to this list, but have been making fractals with Winfract for some
time.  I thought it was time to get serious about Fractint, since it has
useful features (palette editing and rotatable zoombox, to name two) that
Winfract lacks.

So, I've been putting the Good Ship Fractint through a shakedown cruise on my
computer. Generally, it's been smooth sailing with only a few questions to
ask:

I have a second internal hard drive (D:).  Can I access this drive from
Fractint (which is on C:)?

I'd like to give Fractint a large fractal to render in DOS while I do other
tasks in Win95.  Is this possible?  In general, what settings do I need to
maximize Fractint compliance with Windows?

When going into color cycling mode, I've ocassionally noticed that 1 color in
my image palette changes to grey.  This appears to be one of the 2 crossed-out
colors used for the palette frame in palette editing mode.  Is there any easy
way to prevent this from happening?

So far, though, I've been having fun... especially with colormaps ... the <e>
key opens up a whole new world in this respect!!

All are welcome to visit my Winfract fractal gallery at:

I didn't put those numbers in there, they came with the formulas
as posted, and what you said is what I have been wondering
about.  Those numbers were so weird.  On  a lot of the formulas
with changeable parameters, I will throw in a number
and then a different one and sort of  zero in on
something that looks good, but I was wondering if
some of the people doing this can actually envision some of the
results.  I mean, obviously no one will know exactly what
-1.684 will do but do they understand what changeing the
constant versus adding another function will do?

Hi.  Thanks!- I read this after my other post and I am
going to go away and mull it over for a couple of years.
Actually the palette is by Les St. Clair from the contest
entry;  I would not want to steal it without giving credit.

<<snip>>

What article and where can I get it??? I never took calc.....so I don't
think I'd understand Paul's Jan 2 lesson.

I know it's a real challenge to explain a math problem and be limited by
not being able to use math.......but hey....when I was in school math
wasn't nearly as interesting as now that I'm doing fractals. Thanks for the
explanation Jay.....I'll read it carefully.

I wanted to modify Linda Allison's star formula

051597-002   {; Linda Allison May 15, 1997
 z=0;
 c=log(sqr(sqr(pixel))*pixel)*0.2:
 z2=fn1(z)+c
 z=c*(1-z2*z2)/(1+z2*z2)
 |z|<=p1
}

If I replace one of the sqr with tan, atan or sin (etc), I get a three
sided image (Linda's is 5 sided) or 10 sided. I was wondering how to get to
4, 6, 7 or 8 sides. I tried adding a constant as Kathy suggested and got a
more complex 3 or 10 sided image. But that was a fun excursion too. Who
would have thunk math could ever be fun?

Hi Mark!!

You have a nice gallery....I liked your idea of making a "button" out of
the thumbnail.  If you haven't already....you might want to read Linda
Allison's great lessons on color maps and proportioning.....I keep them

Many thanks to Paul Carlson for the wonderful formulas which just kept
on coming for a while, keeping me busy. I found the extensive comments
very helpful in understanding what's going on. So far I have worked
mostly with the four julia formulas, accumulating quite a few pars. Here

  Try the following formula:

051597-002-m1   {; Linda Allison May 15, 1997
                 ; modified by Sylvie Gallet
 ; 1st parameter: real(p1) =3D bailout
 ; 2nd parameter: imag(p1) =3D number of sides
 z =3D 0
 c =3D 0.2 * log(pixel^imag(p1)) :
 z2 =3D fn1(z) + c , sqz2 =3D sqr(z2)
 z =3D c * (1-sqz2)/(1+sqz2)
 |z| <=3D p1
}

        - Sylvie

Thanks so much Sylvie....

I'd send a par as thanks, but Linda's formula is so good it's a snap to
make really good images...and they generate fast.....so I'll leave everyone
to have their own fun.  A word.....you have to set the decomp in the x
options to 256 or you don't get good images.

Which raises yet another question.....if one needs to do this....reset the
decomp for a value other than 0....is there a way to do that in the formula
itself? I got the formula from Linda then had to send out an agonized cry
for help because I didn't know to reset that option.....can hapless users
such as myself be protected?? I spent about an hour before I convinced
myself there was some data I didn't have....very
frustrating......fortunately I knew Linda and Janet and got saved. Someone
stumbling across this really good formula in an archive is not likely to be
so lucky....

Jack...

I think single monthlies would be a boon if we could adopt a common
nomenclature and have a guru of month change.  That way....when I post a
par...I could always make it refer to say.....  jan98.frm .....and we would
all gleefully paste our formulas into a file with the same name until
notified.  The guru's job would be to announce (after donning hat and
official robe)...effective 02 February 00:00 zulu....all formulas and pars
posted will be referenced as feb98.frm ...what do you think??

Hi Angela!

You have a nice gallery too!  In fact, from your site I've already read
through Linda's lessons.  No doubt, gumbycat is THE authority on colormapping.
Now, I'm making my own maps. Thanks to you and Linda for making this info
available!

Mark

Hi Tim,

Some furthermore tests of the simplgif.exe (update ver.) showed no more
problems!
But I got one suggestion:
Is it possible to program SIMPLGIF.EXE to produce a similar output-file (the
makemig.bat file) than that of Michael Peters PARTOBAT.EXE?
It will be great to get the possibility to resume the generation of long
lasting giant fractals..

Thanks in advance!

Guy

Lets forget about people using DOS. Thats like writeing java on a
c64. Anybody, who still uses DOS and has a network, is out of his
mind. He should use windows or some form of unix (perferable the
last). For people without a network an option to not use the network
should be given. That way it would be easy to implement and would run
on any but the worst system.

The Programm should be server and client at the same time, options
could be

new-fractint [--nonet] [--client-only] [--server-only [--port port]] [--pass passwd]

It should be possible to create a network of clients/servers and mixed
fractint programms. Several people could then work together on the
same pool without having to start several networks. Also when several
people around the world combine to a network, they wont all be up at
the same time. The people awake would benefit from those sleeping.

Of cause delays by the network and bandwith must be considered when
writeing a scheduler that distributes patches of one (or more)
image(s) to several computers. e.g. if several patches with the same
priority are waiting to be calculated, the patch requested by a
computer should be done by that computer (or one that is near it
e.g. same subnet) and not by one on the moon. :)
Also slow computers should get small patches and slow networks should
get patches that take long (e.g. with high iteration) without having
much data.

I would realy like to have a version of fractint for the computer pool
here, would be nice with ~50 comps in a net.

May the Source be with you.
            Mrvn

Ever though about installing Linux on your PC? You get allmost the
full speed out of it, you can multitask (which Win95 can't and NT

Nice idea, but it has some flaws in it. You would first calculate the
top left quater of an image. Only after that the 3 other parts are
send away over the net. There you have some problems:

1. With many computers most will wait for one to starts sending out
the remaining pices. Even with two it would take long before anything
is send out and then its only very small pices. Consider you have an
i286 and a cray. the 286 takes to long to calculate a 10x10 square and
sends out the other tree 10x10 squares. Those take nil time on a
cray. The other way, the cray takes 10 secs for the top corner, which
is just above its limit and gives the i386 one square, then there is
no idel comp left and it does the other two squares. Several houhrs
later the i386 is finished with its square and returns its data.

2. The comp takes to long for the top corner, it then sends out the
remaining three corners. What should he do then? There is no part of
the image it could calculate then.

It is probably a better idea to have a treelike structure of servers
and clients. When a client wants to calculate an image it contacts its
server and sends over the data. The server should then check for idel
computers in its subnet. if non are found it sends over the data to
its boss server. A Server that has idel computers (or no boss) should
distribute patches of the queued images to its clients depending on
their idelness, their speed of cpu and netork and depending on the
amount of work a patch probably means.
For the amount of work a patch means should depend on patches next to
it (if already done), on its size and maxiter, on its formula and
number of digits and maybe on the time taken to do some (maybe random)
sample points. When guessing is used the time taken for the previous
pass can also be used. Same with tesseral.

What do you think about that?

I'm not going to mount a spirited defence of my suggestion - after all it's
only an idea for others to comment on.  But I would point out that the 386
would not take hours - after all it would split up the square it was given
into subsquares, and send some of those to other servers, etc...

Perhaps the Cray would know how fast (or otherwise) the 386 was, and not
send it very much data to process.

Also there's no reason to say that if we're finished sooner than expected,
we can't pre-empt calculation on other machines and do it ourselves.

Of cause the symetries should be taken into account before breaking up
the image. Only the unique part of an image is taken and every patch
that is calculated is then mirrored to its symetries and send back to
the client.

Passes, guessing or tesseral could also be used. With passes its clear
what pixel should be calculated, with guessing one would have to do
one complete line of a patch and then start a second server on that
line to do the next guessing pass. The first one could calculate the
second line inbetween. Also the image should be divided into several
smaller patches first so the work can be distributed evenly and one
line doesn't take too long.

My favourite division algorithm (of those done by fractint) is
tesseral. For a distributed algorithm the image should be divided into
smaller patches (depending on its probable time of computation). For
each patch 8 requests (two for each line) should be generated. When
those are computed the patch is eigther subdivided, filled or (if it
gets to small) computed by some fallback method (normaly
guessing). From the time taken for each half line a good aproximation
for the complexity of the sub patches can be derived. For each patch
(except the first) two of the 4 lines will be done already, which give
a good aproximation of the time for the full outline of a patch.

Have you heard of SOI (Simultanious Orbital Itteration)?
The algorithm computes 9 points for a patch and interpolates the pixel
inbetween. When the interpolation gets worse above a certain limit it
divides the area into 4 patches. The new 9 points for that patch are
taken from the original 9 points (4 of them) and are interpolated (5
of them). When the distortion gets to big (too many subdivision in a
short time) a fallback algorithm (guessing) is used to calculate the
full patch.

If 1-Pass is used as the fallback algorithm every pixel is computed
and one might say that nothing is gained. With guessing as a fallback
some pixels are saved, but normal guessing would have saved those too.

The trick here is that the interpolated pixels are used as the start
of the fallback algorithm. Lets say the SOI did 100 iterations before
a patch must be calculated by the fallback. It then has already done
100 itterations of every single pixel in that patch and the fallback
only has to do the remaining iterations until escape or until
maxiter. Of cause SOI hasen't realy done 100 iterations for every
pixel, but interpolated most of them. At the start several iterations
might be done before subdivision. For each iteration it does there
with the 9 starting points, one iteration for every pixel in the image
(except the 9) is saved. For a 1280x1024 image thats over one million
itterations saved for each one done.

Another nice feature of the algorithm is that it gets better while
zooming in. For the full M-Set the first itteration distorts the image
so much that the patch has to be calculated by the fallback. When
zooming in it can do more and more itterations before subdivision and
it can do more and more subdivisions. For the full M-Set it doesn't
matter that the algorithm does the fallback without saveing anything,
since that only takes seconds, but when the speed is realy needed,
i.e. when deep zooming, it realy kicks in and a great increase in
speed is gained. As an example, xfractint took 4 hours on one image
where Almonbread (using SOI) only took 12 minutes and that was with
doubles only.

The SOI algorithm could be used nicely for distributing patches to
several computers. The amount of calculation until subdivision is
small and in a short time many patches can be created. Also the number
of iterations until division is a good rule to guess the complexity of
a patch.

If there is interest, I can supply a perl script that generates a
batch file to generate an image for every par description in a par
file.  Then you can use this with the par file entries generated by
fractint's b command; the generated batch file supports resuming
exactly where the batch process left off, even saving partially
completed images for later restart.  The basic structure the batch
file uses is something like this:

    if haven't done this image yet
    if we have a partial image
        resume fractint with partial image
    else
        start fractint with par definition
    endif
    endif

I had tried to use partobat, but it just didn't suit my tastes.  So,
I wrote a perl script to generate the batch file that I use.  Perhaps
there are some batch file wizards that could improve the generated
script even more.  I also could have written a perl script to do the
processing directly, but writing out a batch file seemed simpler at the
time.

Perl is available for free from your nearest cpan archive site; see
<ftp://ftp.digital.com/pub/plan/perl/CPAN/ROADMAP.html> for a roadmap
and links to other mirror sites.  Perl is very handy for doing large
batch manipulations.  Using perl and my script, I generated an image
for every single PAR entry in the fractxtra package.

One point I was thinking of is when, while one is drawing an image with
tesseral or boundary tracing options with "Fill colour" something other
than normal. With image subdivision regulated by tesseral as suggested
above, this is not a problem, but boundary-traced images could be seriously
fragged. (Yes, I've been known to play Doom, but I think the word is
appropriate in this context!)
Also, boundary traced images are likely to be different anyway, when
computed on a client-server network than when computed as at present,
because islands have a chance of being hit by a subdivision boundary and
hence found by the algorithm. This is not a bad thing in my opinion.

In general, I wonder how useful "accelerated" drawing methods would be in
this environment, except when fill colour is nonnormal.

It would be nice if, instead of computing only subimages, if individual
points or sets of points could be transfered back and forth between
machines in little packets containing coordinates (real and screen), colour
(if known) and any other relevant information. Then, for example with solid
guessing, the server could send out the first-pass points to be computed,
and as they come back (in whatever order) decide for each block whether to
do another pass or not. This would also apply to the SOI algorithm
described and no doubt to others. Communications overhead would become a
serious consideration, but it would smooth traffic out so that it's not a
big lump (subimage) every now and then, while the machine waiting for it
sits idle.

I've been wondering how to distribute the boundary tracing algorithm so
that the result remains faithful to the one-processor case? One idea I had
- roughly speaking, to start and delegate a trace from every point along
the top boundary; subsequently start a trace from the leftmost uppermost
uncomputed pixel; and ignore repeated patches - resulted in a huge
redundancy of calculation. It would be to some extent alleviated if
individual points were to be transferred, with an "abort" signal (which
would have to be included anyway) whenever two regions were recognised as
being equal.

Obviously, servers will need to multitask. Otherwise someone might choke
the network with a big job such that every server will be waiting for
another server to be freed up so that it can have something to delegate
tasks to. After all, calculating a 1280x1024 image could easily result in
several hundred thousand tasks arranged in a big tree.

It would also be good to take advantage of various properties of the
formula itself. As well as pure symmetry, time could be saved in the case
of images containing FracText-type regions or funny bailout conditions, or
PTC/PHC images. In the first case, when the image is subdivided into
chunks, the formula sent out could be optimised to eliminate cases which
cannot arise in the given subimage. In the second, the subdivision would be
the "interlaced" method I mentioned above, with only the relevant formula
sent to each "subinterlace".

This is getting toward what I mean when I suggested a more sophisticated
subdivision technique; one that is versatile enough to recognise and take
advantage of some of a fractal's peculiarities.

Your formula file is very well organized...and I used your pars as

it can't be done already it would be a useful feature.....a sort of combo

First before all Guy,
is your program in the Spanky database ? It is the best place.

And a second remark : do most the users of this list have a mailer made by
a Neenderthal programmer ? What are your problems with attached files, and
with the =3D ? Have you no mime decoding ?

Sorry if it is a stupid question...

Although I've never experienced these problems it appears to be a concern
to many on the list. I believe some time ago it became a general consensus
to avoid attachments- a case of submitting to the lowest common denominator.

But truly, your comment was rather unfair to the Neanderthals. Evidently they
were far too clever to inflict email upon themselves!

No incivility against Neanderthals, but I think that they programmed with
some language machine using a processor made with a piece of silex (or
perhaps they discovered some tools used now on Unix workstations ?). Later
Homo sapiens got Photoshop and began to paint the walls of their caverns.

Clearly out of topic...

Hi Tim,

Some more tests showed new problems: My P90 is hanging after loading c. 75%
of the SIMPLGIF.GIF.. into a viewer or into Fractint.
It is a (800x600) (x=5x, y=5x) = 4000x3000 pixel fractal..

This fault is probably *not* comming from bad HD-clusters, I^we been trying
3x to generate the 'simplgif.gif'. The corresponding 'fractmig.gif' is ok ..
no problems to view the fractal with a viewer or in Fractint.

If someone of the other fractinters would like to make the same test, I can
send you the corresponding .ZIP-file (7.1kB)..


cheers,

Guy

Hi Fractintiers,

I'm trying to locate zeros of a function (an MSet) using Newton's method.

f = a(z^2+c)^2 / (z^2 + b + c)  + c

f' = 2az(z^2+c)(z^2 + 2b + c)/(z^2 + b + c)^2

But z appears in the derivative, and so it is zero everywhere. But I know f
has zeros!   Any ideas Paul?

This derivative is a product of three polynomials.  The product is
zero whenever any one of the factors is zero, so you can get the zeros
of the derivative by finding the zeros of the factors:

    z = 0
    z^2 + c = 0
    z^2 + 2b + c = 0

should post it here, Guy!

I get problems, but not the hanging you get. There are two
rectangles cut out of the left hand side of the result. The final
image is a legal GIF. Can you send me the original PAR? I need the
center-mag values.

Thanks for the counterexample, it is the first one I've seen that I
have been able to get to do something wrong. I couldn't duplicate your
earlier example - I wrote you about it but for some reason the mail
bounced. (Later - it bounced just now too.)

I need to determine if simplgif's encoder or decoder is failing. In
the past, encoder problems always resulted in an illegal GIF. That's
not happening here.

I'm talking from my own experience here - I can still hark back to those
days (Version 17.2 if memory serves).

My advice is to keep at it - my very earliest attempts were pretty bland,
and even now I spin off something grim.

I started playing around with "Fractint.frm" itself - taking the formulas
there and tweaking them about, replacing things like "sin" or "sqr" with
"fn1" for example (I also recommend Beacham's tutorial). That was largely
to work out how the things actually work.

The first formulas I wrote from scratch that were worthwhile were based on
equations lifted straight out of an astrophysics textbook with gleeful
disregard for their physical significance (as if I understood them in the
first place!). I include them below for entertainment purposes.

But yeah, muck around with what's out there, get a feel for what sort of
things do what, and practice. Hack, in other words. I suggest you make some
acquaintance with the mathematics behind what's going on - it's not
necessary but it leads to such satisfying results. I'm working with
orthogonal functions at present - I've been at it on and off for years
(partly because I'm having to do everything by hand) and the complete
collection is standing at 200kB, though it is certain to rise before it
gets to beta-testing.

Indeed; here's a little thing that takes 20sec on my machine. One of my
all-time favourites.

Spectral_Flow      { ; It's so easy! I like to colour cycle this one...

  31>W0zW0yV0w<32>102000100<33>x00z00z00<23>zD0
  }

I had actually written the "Liar" formula myself at one time before
it was added to fractint.frm.

So here's my liar formula file (which I'd called "chaotic dualist"). I warn
you that the formulas may have little to do with lying.

It uses my spectra1 map - something I often use while exploring. Anyone
know how to make the map more accurate physically? (I'm needing to convert
wavelength->RGB!)

comment {Apparently, one can use fuzzy-logic techniques to resolve
paradoxes of such types as the Epimenides (or Liar) paradox
by taking such as statement as being, say 40% True.
The thing is, your decision as to the truth-value of the
original statement also has a certain fuzzy truth-value,
so one enters into a dynamic process which finally levels out
at a conclusion of one sort or another.
Sorry if I seem vague, but I didn't quite get the hang of the
Scientific American article at the time, and beyond knowing that
it was one of Ian Stewart's "Mathematical Recreations" columns,
I can't give its source.

  Hey, what are these formulas for, anyway? (To do the work in the textbook?
Yah, right. :-P) I've got a bunch of formulas in Chemistry I can work with
when I get the spare time. ::Wonders what a fractalized specific heat formula
would look like:: :-P

  BTW, at the moment I'm doing Geometry homework and looking at fractal Web
pages at the same time. Euclidian geometry just loses so much of its charm
when compared with chaos. :-)

Here is another 5-pointed star I found completely by accident

Hi,
     The fractint palette editor is a very useful tool however there is at
least one bug (or inconvience?) namely that the undo command (which I find
very useful :) ) will not undo commands entered before color cycleing with
the > or < keys. This is probably a well known bug but I thought I'd point
it out just in case.

Ben,

 -      The fractint palette editor is a very useful tool however there is at
 - least one bug ...

Here's another one: hit "l" to load a palette, then hit ESC without
choosing a palette.  The last two colors of the palette are modified, and
you must remember to undo if you want your original colors back.

I haven't had that problem in 320 x 200 and have been using it a lot lately

Hmmm, never happens to me.  I have Fractint 19.6 when I'm in a DOS mood,
and nothing like that happens to me.
What video card do you have?  Maybe it doesn't like VGA mode much.  Just

I don't know, but what you write reminds me that when a few months ago I began to
experiment with writing formulas, I dusted off my copy of an ancient textbook of
analytical geometry, and tried to put some of the equations I found there into a
formula one way or another, often taking liberties with the mathematics of it. For
example, here is my rendition of a damped vibration curve, the equation of which
is y=ae^(-kx) * sin(bx+c). The constant c is omitted in the formula below, not so
bad since it may equal zero, but the hard coding of the sine function is abandoned
too. This arbitrary maneuver of course destroys the mathematical integrity this
particular "fractalization" may have had, but what of it! I was after an image,
not mathematical rigor. In any event, you will undoubtedly discover something
other than a damped vibration curve in it.

   }

Nice personal fractals, especially in the 2nd half of you page, but when
you show images made by others, you must give the name of their creators.

What is really needed is a way to specify formula defaults for everything
from the view area to the z params and things like "outside=real" if
necessary.

Built-in types have defaults,e.g. put in lambda, and there are nontrivial
values on the 'z' screen automagically, chosen to generate an interesting
image.

From: Kerry Mitchell <[e-mail]>
Subject: Re: (fractint) Triangle Inequality Coloring
Date: 17 Jan 1998 08:34:34 -0700 (MST)

Peter,

The triangle inequality coloring method (at least, the one I developed),
colors the fractal based on a fundamental theorem of complex numbers.
Given 2 complex numbers a and b, then

|a + b| <= |a| + |b|, and
|a + b| >= ||a| - |b||,

where || represents the magnitude, not Fractint's magnitude-squared.
Basically, since complex numbers have both magnitude and direction, the
resulting magnitude of the sum of two numbers lies somewhere between the
difference of their magnitudes and the sum of their magnitudes.  For
example, if we use 3 and -5,

|3 + -5| = |-2| = 2 >= ||3| - |5|| = |3 - 5| = |-2| = 2

At one extreme, the 2 numbers are pointing different directions, so adding
them results in subtracting their magnitudes.  At the other extreme,

|2i + 4i| = |6i| = 6 <= |2i| + |4i| = 2 + 4 = 6

So if both numbers are pointing in the same direction, then adding them
results in adding their magnitudes.

This can be visualized by considering a triangle in the complex plane.
Start at the origin (0,0) and draw one leg out to a.  From there, draw
another leg to a+b.  Then, draw the third leg from (0,0) to a+b.  The two
extreme cases are cases where the triangle has zero area, since all 3
legs lie on one line.

Anyway, back to fractals.  The important thing is that, if we replace a
with z^2 and b with c, then

||z^2|-|c| <= |z^2+c| <= |z^2|+|c|, or

lowerbound <= |current iteration| <= upperbound.

This can be rescaled to:

0 <= (|current iteration| - lowerbound) / (upper-lower) <= 1.

Multiply by 2pi and you have an angle that shows up nicely using
Fractint's decomp option.

Here's a formula file using the triangle method.  I have also used
averaging to reduce banding.

Enjoy,
Kerry Mitchell

Subject: Re: (fractint) Triangle Inequality Coloring
Date: 17 Jan 1998 08:34:34 -0700 (MST)

Peter,

The triangle inequality coloring method (at least, the one I developed),
colors the fractal based on a fundamental theorem of complex numbers.
Given 2 complex numbers a and b, then

|a + b| <= |a| + |b|, and
|a + b| >= ||a| - |b||,

where || represents the magnitude, not Fractint's magnitude-squared.
Basically, since complex numbers have both magnitude and direction, the
resulting magnitude of the sum of two numbers lies somewhere between the
difference of their magnitudes and the sum of their magnitudes.  For
example, if we use 3 and -5,

|3 + -5| = |-2| = 2 >= ||3| - |5|| = |3 - 5| = |-2| = 2

At one extreme, the 2 numbers are pointing different directions, so adding
them results in subtracting their magnitudes.  At the other extreme,

|2i + 4i| = |6i| = 6 <= |2i| + |4i| = 2 + 4 = 6

So if both numbers are pointing in the same direction, then adding them
results in adding their magnitudes.

This can be visualized by considering a triangle in the complex plane.
Start at the origin (0,0) and draw one leg out to a.  From there, draw
another leg to a+b.  Then, draw the third leg from (0,0) to a+b.  The two
extreme cases are cases where the triangle has zero area, since all 3
legs lie on one line.

Anyway, back to fractals.  The important thing is that, if we replace a
with z^2 and b with c, then

||z^2|-|c| <= |z^2+c| <= |z^2|+|c|, or

lowerbound <= |current iteration| <= upperbound.

This can be rescaled to:

0 <= (|current iteration| - lowerbound) / (upper-lower) <= 1.

Multiply by 2pi and you have an angle that shows up nicely using
Fractint's decomp option.

Here's a formula file using the triangle method.  I have also used
averaging to reduce banding.

Enjoy,

Paul,

 - Built-in types have defaults,e.g. put in lambda, and there are nontrivial
 - values on the 'z' screen automagically, chosen to generate an interesting
 - image.

Most of the formulae I have made will provide default values for entries on
the z page that are left at zero; this is part of the formula, not the PAR
file that sets defaults.  However, because these values are assigned when
calculation actually begins, they are not reflected on the z page, so
unless you look at the formula code, you won't see what's going on.
Providing the defaults is mostly there for folks who plug numbers in at
random; this lets them at least see something before fiddling with numbers.

Angela,

 - You got my idea exactly!!!  Can such a feature be added to fractint??

Theoretically, anything can be added to FractInt. :)  The question is, will
somebody do it?  There are things I want to do with the FractInt code, but
currently I am so overwhelmed with other things that I haven't had a
chance.  I haven't even had time to update my own web gallery... :(

 - Another question.....I noticed in some of the pars that Jay Hill posts that
 - it reads
 -
 - frm:formulaname {formula here}
 -
 - If I paste this whole thing into my formula file (currently jan98.frm),
 - fractint doesn't pick up the formula.

Just take out the frm: before the formula name.  frm: is a prefix you put
on the formula name so that you can put a FRM inside a PAR.  When you take
the FRM out of the PAR and put it back into a FRM file, you need to take
off the frm: prefix.  Does this make sense?

 - But I suspect there is a good reason why Jay uses this methodology.....???

Yep, so you can cut & paste the PAR and have everything in one file.  With
the frm: prefix, you can put the PAR and the FRM in the same file, and it's
easier to pass around your work.  Before the prefix was available, you had
to pass around a PAR *and* a FRM, and this was a little more cumbersome--it
was too easy for a PAR to get separated from its FRM, and if you don't have
the FRM, the PAR is no good.

Courtesy of Tim Wegner:

***************************************

Make a file called makepar.bat (or whatever) containing:

for %%f in (*.gif) do fractint %%f makepar=%1 batch=yes

Then type in:

makepar mypars

This will put PARS for all the GIFs in the current directory in the
file mypars.par.

***************************************

[I should add that fractint either has to be in your PATH or in the
directory that the gifs are in.]

It works fine.  I used it to extract the pars from the over 1,000 gifs on
Jill Lawson's web page, though the saving in space was not huge, due to
the small size of the images she has posted.

When fractint loads a par from a par file it will read the formula if the line
starts with "frm:".  It ignores such a thing in an frm file.  If you want the
formula in your jan98.frm file, just cut and paste and delete the "frm:"

For a lossless format, PNG is outstanding (much better than Tiff and BMP, and
for 256 colors, GIF), and is *the* format of the near future since it is also
Public Domain (unlike GIF).  For Windows 3.1/95 most graphics programs support
PNG, e.g., PhotoShop, PaintShopPro, Graphics Workshop, etc.

And note that in the next major revision of Fractint, GIF will be drop-kicked
to be replaced by ...... PNG!

If it's good enough for Tim, it's good enough for me.  :^)

So it behooves everybody to get on the PNG bandwagon as soon as possible and
to get the necessary graphics software to handle PNG images.  I archive all of
my ultra-hi-rez images as PNG.

Hi Fractintiers,

We could change the batch file slightly. If you want to do certain
GIFs and as I, don't want to much in your path so Fractint is not there,
try this.  Make a subdir off your fractint dir. Move or copy your GIFs
to it. In DOS run this bat...

 for %%f in (*.gif) do ..\fractint %%f makepar=%1 batch=yes

Alas, this does not work for me, neither does the original! I get
an error message. Even when running in the fractint dir.

C:\JAY\FRACTINT.196>makepar mypars

C:\JAY\FRACTINT.196>for f makepar=mypars batch=yes
Syntax error

So what is wrong?
Jay

Because Fractint is headed that way!  When Fractint goes truecolor, all
such images will automatically be saved as PNG.  It (with 256 colors)
compresses much tighter than GIF, it is lossless, and it is freeware
(unlike GIF). The next version of Fractint will be able to read these PNG=

files, but not bmp or tiff.  Until then, I use QPV (a shareware graphics
viewer) to view PNG images in DOS, and Graphics Workshop to view them in
Windows.

[re:  adding default parameter values to formula files]

I'll speak out as (possibly) the only voice against this idea, at least,
as far as coding it into Fractint goes.  I like Damien's way of adding
defaults to his formula, but that adds extra complexity to the formula.  I
tend to write general-purpose formulas that have no clear defaults.  What
I suggest is that, when writing a formula, you include a default parameter
file, and/or a narrative explaining how to use the formula.

To include another thread into this overused subject line, is there a good
compilation of narrative (not par files or 2 word comments in formulas)
explanations of coloring schemes?  For an example, see the recently
posted, terribly eloquent tome by yours truly about the triangle method.
:-)

Does something like this already exist?

There's also a version in my formula file, currently available on my

Kerry, isn't it nice to know your technique is so popular? :)

Peter,

You may want to add a statement like, "periodicity=0" to the parameter
files--it worked for me.  Personally, I put "periodicity=no" in my
sstools.ini file to turn of peridocity checking logic, but others like to
use it.  To each their own.

Date: 17 Jan 1998 15:57:52 -0800

Hi Kerry,

Just to start a new thread and a good one it will be :-)
Wizzle has Linda's lessons (as must Linda also)
http://wizzle.simplenet.com/linda/lindas_lessons.htm
But perhaps that is not what you are asking. Color maps
are one thing. Color schemes must by things like bof60,
atan, iter etc.  We must have a dozen built into Fractint
and there may be another dozen crowbarred in with
obscure formula.  A discussion of this would be useful.

How about

a) built-in methods (there might be several I have not
noticed, even though I have been a fractint user
for many years).

b) methods clever folk have used in extending Fractint

c) methods folk have seen or used in other products
that could be 1) crowbarred into Fractint or 2) added
with special new code.

As a start on c), I used a special lighting effect in
DEEPZOOM
http://www.geocities.com/CapeCanaveral/Lab/3825/Software.htm
to show detail otherwise unavailable with limited
resolutions and colors.

And about compilations. I want to start a FAQ for this list. Not
a FAQ, actually, but an iFAQ.

That is "inFrequently Asked Questions"

This document will be available at my site and contain essays
(the really good explanations / discussions that actually do
occurs here once or twice a month).  I will be scanning my
archives for candidates. If one of your articles is selected,
I will be asking for your permission to include it or slightly
edited copies in the iFAQ.  If there was an article you would
think should be included, let us know. If there becomes a
flood, send mail to me.     mailto:[e-mail]

As an example, I would think

Paul Derbyshire's series on Jan 10:
  generalized Mandelbrot/Julia formula
  Siegel disks
  Distance estimator

Paul Derbyshire's Calculus lesson
  Re: (fractint) Formula Question  January 02, 1998 2:32 AM!

Some of mine (in case I'm the only one):
  Fractal encryption December 28, 1997
  Another warning. was Re: (fractint) DEEPER Program December 28, 1997
  Re: (fractint) Feigenbaum Point Nov 17, 24 1997

Kerry...

As a user I prefer Damien's method because I don't have to go searching for
pars.  I'm willing to bet that someone using a formula a year from now
would have a major struggle to find a par to go with that particular
formula....it's happened to me after I downloaded orgform.zip and got 10
zillion wonderful...but sometimes baffling....formulas.

Oh....good idea Jay!!!

A friend of mine who is new to fractint wants me to do a lesson on atan,
real, bof60, etc.....I've barely figured them out myself from a user
perspective......but at least I now know how to provide examples.  I'm
adding a sort of footnote lesson to Linda's on colormaps which is in the
works at...

http://wizzle.simplenet.com/fractals/wizmaps/wizmaps.htm

It's not quite finished but comments are welcome.  I'd love to be able to
link to more technical explanations such as yours and Damien's as well as
to other coloring methods like Damiens....and now Paul Carlson's.  I think
of these methods as "filters" to the basic iteration way of doing business.
 Maybe as a group we could hit all levels of knowledge.....I volunteer for
the basics of just making a pretty picture.

I do like your tutorial on color mapping. There is one small problem
however - the last image (81avw076.gif) won't load in - presumably there
is a minor problem with a missing link.

hrm? 2az(z^2+c)(z^2+2b+c) is zero only if z=0, z^2+c is 0, or z^2+2b+c=0,
so your zeros of the derivative are at 0, +/-sqrt(-c), and +/-sqrt(-2b-c).

The zeros of f are +/-sqrt(c).

Hi Fractintiers,

And now presenting another fractal exploration by Dr. J, the mad
scientist.  See http://home.san.rr.com/jayrhill/Story/Story.html

Tonight, has he tried to compute one too many fractals after dark
and found more than he intended!

It is called Fractal of the Night (Lost Head).

Has Dr. J uncovered foul play in fractal land?  Point your browser to

http://home.san.rr.com/jayrhill//FotN/FotN17.html

and find out if having a map of fractal land helps Dr. J solve the mystery.

Maybe because tiff is restricted to truecolor and lossy like JPEG  (I

One thing to note is that because your zeros are both double roots, you
will get rather slow convergence because they won't be critical points of
the Newton mapping. Also, Newton's method becomes a 0/0 limit approaching
them.

The relaxed Newton method, z -> z-hf(z)/f'(z), can solve that problem; find
out the derivative of z-hf(z)/f'(z) at the zeros of f and choose h to make
this derivative zero.

12  -1.423229349915665  0.0
24  -1.44051078460579   0.0

These I find with numerical procedures where as I would think
analytical derivatives would be better.

From my C++ code:
for(int k=0; k<32; ++k){
 Complex z,z0=sqrt(-c),dz,delta; Complex eps(1e-14,-1e-14);
 z=f(Period, c);
 dz=(f(Period,c+eps)-f(Period,c-eps))/(2*eps);
 delta=(z+z0); //  delta=(z + or - z0);
}

where

Complex f(int p, Complex c){
// p=period
 Complex z=sqrt(-c), z1;
 for(int k=0; k<p; ++k){
   z1=z*z+c;
   z=a*z1*z1/(z1 + b) + c;
 }
 return z;
}

Now when I plug the exact derivative from MathCad into dz I
get zeros.

f = a(z^2+c)^2 / (z^2 + b + c)  + c

f' = 2az(z^2+c)(z^2 + 2b + c)/(z^2 + b + c)^2

Put initial value in for z=sqrt(-c) and we get zero!
Why does finite difference work better?  To see a Mandelbrot set
you start the iteration with z at a critical point. I do that. I get very
nice MSets   http://home.san.rr.com/jayrhill/FotN/FotN17.html
for example.  And the Table above shows the centers of these
components - zeros of f.

I don't see how a relaxed z -> z-hf(z)/f'(z) method would work.
h times zero is zero.  And if I put z=sqrt(-c) I get a single
root, right? How is that double?  I seem to be getting not
0/(z^2 + b + c)^2 as I approach but always! The denominator
is not zero, so I don't need the 'Hospital rule.

Thanks for looking.

Jay

I'm not quite sure I understand the probl;em. You say you get zero using
initial z of sqrt(-c), but that's normal; it's a root, so of COURSE Newton
will give zero. You should get nonzero values for initial z of, say
sqrt(-c)+epsilon... don't you?

Oh good grief, I just noticed I put the wrong formula into MathCad, so it
of course, gave me the wrong answer.  I'm not solving the right problem.
I got it working just now. I'll write it up shortly.

I'm working on wizzle's question, you see....

Wizzle asked:

Later, and thanks,

Sure, I think Cliff is interested in what we discuss here.

And about the MAKEPAR.BAT...
Here is what I do:

C:\JAY\FRACTINT.196>makepar wwwwwww

C:\JAY\FRACTINT.196>for f makepar=wwwwwww batch=yes
Syntax error

C:\JAY\FRACTINT.196>

C:\JAY\FRACTINT.196>type makepar.bat
for %f in (*.gif) do fractint %f makepar=%1 batch=yes

I checked my DOS books from PC Magazine, there is nothing
wrong with the command. Is this another Micro$oft Win95 thing?
Not doing old DOS stuff??  Anyone????

I just tried this which should do dir on each .gif file.

C:\JAY\FRACTINT.196>for %f in (*.gif) dir %f
Syntax error

Oh well....

Subject: (fractint) Fractint and NT 4.0
Date: 18 Jan 1998 20:17:53 +1030

Hi

On my current machine I used to run the Win 95 O/S. Fractint worked fine
and I usually used the:

SF6 SuperVGA /VESA Autodetect 800 X 600 X 256 video mode
or the :
SF7 SuperVGA /VESA Autodetect 1024 X 768 X 256 video mode

I  changed the O/S to NT 4.0 and find that I can only use a limited number
of video modes:

F3 IBM 256 color VGA/MCGA video mode.
and the
Disk/RAM Video for background fractals

The machine still has the same hardware and is operating perfectly. Can
anybody tell why I can't use my preferred video modes, or is Fractint just
not compatible with NT 4.0.

Short and unfortunate answer: NT's DOS support bites the bag. You'll have
to go back to Windows 95, stick to disk video, or get another machine with
Windows 95; or install a DOS or 95 partition on the NT box and a boot menu.

Long answer: NT doesn't support any DOS video except text and VGA, nor DOS
access to long file names, nor a host of other things Windows 95 does.
Long term solution: Complain to Microsoft. Threaten to install 95 and
boycott NT, 98, and any other Windows if it won't support DOS fully. Or
something.

Thanks Paul

Now that's what I call a quick reply - less than 15 minutes after posting
my message to the list. You've saved me wasting a lot of time trying to get
the video modes to work; Thanks.

I do have and old 486 with Win 95, I'll use that - but it's a bit slow

heh. well, I'm a bit of an addict, often on perpetually during the
weekend nights.

Then I strongly suggest making a smallish partition on the NT box with
either an old secondhand DOS 5, or DOS 6.22. (Using the Windows 95 install
disk from the 486 to put a copy on the partition is probably illegal and
would use a heckuva lot more disk. Although then you could multitask, and
maybe even run apps off the NT partition unless it uses NTFS and 95
doesn't know NTFS.)

Mark...

Very nice images!!!  I hadn't tried epsilon cross and I like the way your
first star came out......that is one great formula, huh??  I did edit out
the red, though which I found a bit too busy....I matched the red to the grey.

You might want to try Sylvie Gallet's variation of Linda's formula
too...here's a re-post just in case you missed it the first time

051597-002-m1   {; Linda Allison May 15, 1997
                 ; modified by Sylvie Gallet
 ; 1st parameter: real(p1) = bailout
 ; 2nd parameter: imag(p1) = number of sides
 z = 0
 c = 0.2 * log(pixel^imag(p1)) :
 z2 = fn1(z) + c , sqz2 = sqr(z2)
 z = c * (1-sqz2)/(1+sqz2)
 |z| <= p1
}

Since you can increase the number of sides, color mapping starts to become
a challenge as the images become more busy. I used a seven sided star on my
color mapping page as an example for that reason.

For the formula fiddlers.....replacing sqr in Linda's formula with tan and
adding a constant introduces some very interesting complexities to the
images. Thanks again to Linda and Sylvie for giving us this great toy.

Lee..

Yuppers...knew that...know that adding a border to a fractint gif or text
(like my copyright) also goofs up the code.  I do a lot of graphics for the
web....and even like jpg for some applications (buttons and thumbnails).
BTW....I've collaborated with a web friend at

http://www.enchantress.net/fractals/

She uses my fractals to make really nice backgrounds....and I've got her
fractinting too!!!

Nother question.....

I'd like to print some of my fractals .....say in about  24" x 18" size
.....suitable for framing.  What is the best way to go about getting a good
quality print? I've never done any publishing at all so would appreciate
very step by step advice, including mail order sources for
printing....although I'm in lost angeles and could probably find a printer
here if I understand what is required. My largest fractals are in the 1024
x 768 format.

Ben...

Someone has said that a copyright is only a right to sue.  Basic processes,
such as math, can not be copyrighted, btw. Algorithms or programs, such as
fractint, can be copyrighted to some degree.....but program interfaces
cannot be copied so long as the code is altered.  Images can be copyrighted
but the copyright may not be sustained if the image is "substantially"
altered (which it can be). I would say it's anyone's best guess if the
formulas written for fractint can be copyrighted. And frankly, why bother?
In order to do anything with the copyright you have to sustain a lengthy
and expensive legal process..........I can see maybe doing that for
fractint.....but for a formula?

More extreme solution:  Dump Windows entirely in favor of Linux and
XFree86, where you can make fractals *any* size using the -geometry flag
of XFractint.  Of course, if you want your fractals to fill the whole
screen, this may not be the best option... SVgaLib Fractint anyone? :)
    P.S.  I, unfortunately, still have to use WinBlows occasionally, but
only because my printer doesn't understand Postscript and there's

Maybe that's why no one was there... they saw the ad, thought "What a

left.  I was going to check it out, but it seems you took it down

Yup!  I'm playing with your tangent variant now.

Yeah, I know.  I've developed this compulsion (probably from too
much time in real and virtual darkrooms doing color balancing)
for balancing palette colors so that the average image color is
approximately neutral (grey).  Plus there were thematic reasons
for including a dark red.  If any of you are Babylon 5 fans, how
many themes from the show can you find in the image (5s01)?
Just curious.

Hi Tim,

Not knowing if I'm able to reach you at @phoenix.net, I send this .zip to
@xmission.com...

There is a strange behaviour of SIMPLGIF.EXE considering the TYPE=JULIBROT..
The attached files are:
 * ORIGINAL.PAR is the original.par-file for a 3D-fractal (stereoscopic, for
crossed-eyes viewing). Let it run to see the "original" image.
 * the makemig.bat is produced by simplgif.exe (update ver.)
 * the timtst2.par is also produced by simplgif.exe (update ver.)
The resulting fractmig.gif works well but dont show the original image and
the produced image is repeated 5 (x5) times (in this case). I must say that
this effect is not bad (I must think about what I can do with it), but the
effect is surely unwanted..
Will make further tests...


Best regards,

Guy

To get a very nice output around this size I have been using an HP color inkjet plotter.  Prints at 300 dpi.  Extremely inexpensive, as it prints on plain paper and takes only a few minutes.  I use one at my work, but you can find them occasionally at blueprint service shops.  If you follow this up, plaese let me know, as I have some tips for getting an optimal image.

Folks,

A gentle reminder, we have another glut of off topic or personal
messages on the list.

Please make sure before posting that your message is of GENERAL list
interest, on topic, and not so personal it is only of interest to
the person you are answering. The message traffic is high, but
that's OK if you don't have to sort through many messages to find
one on fractals.

I assist people in making museum-quality custom prints in small runs of the
size you mention.

My process is to generate a ultra-high resolution image (18432x13824) of
the fractal image.  I then use that to make an 8x10" Ektachrome transparency
using a Kodak LVT which writes on the film at an astounding 2032 dots per
inch (it is a state-of-the-art device).  Then, this trans can be used in
standard photographic enlarging processes to make reversal prints (Cibachrome
is the best, but Fuji also makes an excellent high-grade reversal print paper).

(For making Cibachrome prints using 8x10" transparencies, which not many
places can do, the best in the country, if not the world, is Weldon Color
Labs right there in "Lost Angeles".  They do a lot of work for the Getty
Museum and have a full understanding of not only printing, but displaying
aspects such as lamination, mounting, and display framing.  They are high
quality folks, yet are reasonably priced for what they do.  I'm *very*
impressed with them.)

Let me add this whole process does not come cheap.  But I can guarantee you'll
be blown away by what results.  The biggest advantage besides very high
detail is that the colors are much more accurate to the RGB color space the
original images use.  Unfortunately, any ink process has trouble reproducing
(to my satisfaction at least) a lot of the brighter RGB colors fractal artists
like to use.  And inkjet outputs, even Iris, just don't compare to a well-
made Cibachrome in overall beauty and color saturation.  In addition,
Cibacrome is semi-archival, especially when properly laminated, and has a
life measured in several decades when displayed indoors.  No ink print can
claim the same, even with so-called "archival" inks, except those few
printers which use pigmented inks (most use dye inks, including Iris).
(The *only* advantage of the Iris and similar printers over my approach is
that one has the choice of many different paper substrates for custom
texturing -- Cibachrome has a smooth, very glossy, mirror-like look.)

For further references on the beauty of this approach, talk to Lee Skinner,
Noel Giffin, and Sylvie Gallet, who should give you a third-party and
objective assessment of what I write here.

Now, if you want high quality lithographs for large quantity runs, I can't
help you there, but let me suggest you use a printer familiar with high
definition 6 or 7 color printing -- avoid the standard 4-color printing unless
you *know* the 4-color printing can handle the colors you use.  PhotoShop
can help you here -- simply display the RGB image in PhotoShop, then select
the CMYK preview and see how it changes -- the CMYK preview gives you an
approximate idea of how it will look like if printed with an ink process --
if it looks fine there, then you can consider printing with an ink process.

BTW, I am setup to generate 18432x13824 Fractint images for my method of
printing.  I also have some lower resolution printing options as well.  Let's
talk if you're interested.

Subject: (fractint) From Paul Carlson
Date: 18 Jan 1998 13:16:43 -0800

Although I still can't send email to the list, I have been able
to receive messages from the list and I have a few assorted
comments.

1) Windows NT problems.
The problem is, that unlike Windows 95, a DOS box under NT has
no direct access to hardware, including the video card.  Although
it is possible to configure a dual boot, this is not as easy to
implement as some of the books suggest and from what some of the
experts tell me, seldom works without causing a host of other
problems.

2) Why PNG instead of BMP or TIFF?
There have been several excellent reasons given to which I'll just
add: The baseline specifications for both formats support only
uncompressed images for 24-bit color (which Lee's images are).
There are extensions to the TIFF spec that allow for LZW and
JPEG compression for 24-bit color, but many TIFF readers do not
support them (and LZW compression does not work all that well
with 24-bit color anyway).  Uncompressed 24-bit image files are
VERY big in both BMP and TIFF formats:
     BMP  = 3 * image_width * image_height + 54  bytes
     TIFF = 3 * image_width * image_height + 164 bytes

3) Modified GIF's lose Fractint info.
The fractal info (type, coordinates, etc.) that Fractint puts
into a GIF file is put (I assume) into a GIF extension block
which is ignored by most image manipulation progams and so
is not written back out when the modified image is saved.  It
should be possible to write a program that takes the original
Fractint GIF file and the modified GIF file and creates a third
GIF file that contains the modified image with the GIF extension
block of the original image.  Is there any demand for such a
program?  If there is, I'll give it a try when I find the time.

4) Loading a colormap messes up the current image.
With my video card, if I've just completed a fractal and
decide to see how it looks with a different colormap, I press
the 'E' key and then the 'L' key and select a different colormap.
All works well except that a short line (looks like a minus sign)
always appears at the same spot in the image.  I've heard that
others have had more serious problems trying to do the same
thing.  My solution was to write a small program that I called
NEWMAP which works for 256 colormode images.  The program takes
as command line arguments the name of a GIF file and the name of
a map file and overwrites the colormap in the GIF file with the
colors contained in the map file, leaving everything else intact.
If anyone would like me to send them a copy of the program, just
send me an email:  [e-mail]

I hope some of this is useful.  There have been several other
discussions that I've wanted to take part in, but I can't remember
now what it was I wanted to say.

Paul Carlson
PS.  There is a particular fractal image that I use as wallpaper on
both my machine at home and at work.  It has these qualities that,
IMHO, make it a good choice for wallpaper:
1) It's not distracting while working, yet people tend to notice it
(which has allowed me to introduce several peaople to fractals).
2) It has a nice open area in the upper left quadrant where you can
put a lot of icons without obscuring the image.
3) It is a good example of fractal self-similarity which has helped
me explain fractal concepts to people.
4) And finally, it's a pretty nice image (one of my favorites,
actually) that has a nice, solid look to it - almost like it was
cast in bronze (it's 1024x768 res.).
Anyway, if you're interested, you can download it directly from
the web using this URL:

    It would probably be much faster

    Still nobody there though...Ill come back later and have

family was one of the lucky one's to high-tail it out of Europe before it

    A more user-friendly, better tested version of the DEEPER program can be
dowloaded at: < http://boralf.agsci.colostate.edu/~jason/personal/deeper.html >.
The zip file includes the executable, source code, readme file, and a modified
.CFG file (you can either copy it over FRACTINT.CFG or just modify your existing
.CFG file to match the one I provide).  The executable has been through many
more tests, and seems to be portable.

    For those who don't know, DEEPER is a companion program for FRACTINT 19.6
which allows the unattended zooming of the Mandelbrot Set (and probably others,
too).  Using a simple 'fringe recognizing' algorithm, DEEPER performs zoom after
zoom on th M-Set without human guidance.  For more info, read the README file
which can be viewed at the URL above.  Comments, suggestions, etc are
appreciated.

P.s., I don't think that finding a fractal which resembles a Nazi symbol
necessarily means that the finder practices or subscribes to Nazi-oriented acts
or philosophies.  Same goes for users of Microsoft products, I hope...! :)

  At least you THINK. ::Evil grin::

  No, really, I'm not a Nazi. It's just weird to see stuff like that in
fractals. Who knows, maybe eventually I'll find a fractal that looks exactly
like the script for Romeo & Juliet. :-)

  In case anyone cares, here's the parameter file for the Nazi fractal:

  Nazi               { ; It's a Nazi plot! Mr. Mandelbrot was brainwashed!!
  reset=1960 type=mandel
  center-mag=+0.39960241016028810/+0.19543117373730450/1.833849e+009

  }

  Or you could just check out the image on my Web page at
http://www.geocities.com/Area51/Cavern/8881/index.htm in the fractal section.
(Just for the one or two people who might end up trying to figure out why they
can't find it in the Wheel of Time section. :-P)

Perhaps the policy should be that a par is the price of an off-topic post
(though I suppose you could say it then becomes on-topic, which is OK).

Guy,

I can receive your mail, I just can't answer you directly. So you can
email attachments to me. Please don't post any messages with
attachments tgo the list.

Your previous example was a genuine bug in simplgfif. This time it
was the *decoder*. The no bugs have yet been discovered in the
encoder. At the moment I don't need mopre tests of simplgif. I will
make a new version with a new decoder. I'll use the same decoder that
Fractint uses.

Here's an interesting note. We have eliminated the 2048 in the
developer's version of fractint. Fractint can now do simplgif's job!
You just make an appropriate diskvideo mode, load the MIG, and save.
Of course with the developer's version, you can make a 4000x3000
pixel image directly, so you don't need the GIF approach.

One advantage of Fractint over simplgif is that it can use extended
memory for diskvideo, so the large temporary file is not made.

Subject: (fractint) D&C bug but not in simplgif.
Date: 19 Jan 1998 00:31:16 -0500 (EST)



Using the attached makemig.bat, PAR file, and formula, Fractint 19.6
hangs calculating the second image at line 812. This can only be resolved by
killing the DOS session.
The partial frmig_01.gif generated by savetime=10 is a valid GIF89a, and
it and the completed frmig_00.gif have large gaps in both white and black
sections that don't belong, can't be guessing artifacts as 1-pass is used,
and don't look like a bad bailout condition either.
When the partial is restored into a new Fractint session,it resumes at
line 808, and it gets at least to line 1016 without problems, oddly enough.
(Perhaps it only happens with batch=y?)


Note about the formula: the formula is from Mandelbrot's
_The_Fractal_Geometry_of_Nature_, 1983 edition, from page 464. I managed
to duplicate the Julia set depicted in its Plate VIII, as well as the
M-set in Plate X except that the latter is largely obliterated by a huge
blue disc, which must be a bug in the formula Twofo_M that I am at a loss
to find (nudge nudge, wink wink)

Subject: (fractint) Explanation, formula and par:  bubble method (long)
Date: 18 Jan 1998 22:45:47 -0700 (MST)

I didn't originate the bubble method, but that didn't stop me from writing
about it, and adding some of my own variations to the collective.  Wizzle
and others--I can empathize with not knowing how to use a formula.  So,
I've included sample pars and comments in the code, that will hopefully
clarify what I had in mind.

Enjoy,

The Bubble Method

The bubble method is an extension of Fractint's bof60 scheme.  In
bof60, the interior of the fractal is colored by how closed the iterate
comes to the origin.  In the bubble method, a specific value is set as
the threshold.  Each step, the magnitude of the iterate is compared to
the threshold.  If the current magnitude is smaller, it becomes the new
threshold level.  The effect is to cover the fractal with "bubbles",
circles the radius of the threshold.  Below a certain threshold value,
the image is a dust of small, disconnected bubbles.  At a particular
theshold value, which varies with the parameter c, the circles all
touch.  Beyond this, the circles squish into each other, like mounds
of soap bubbles.

At bailout, if the image is colored by the last threshold, each bubble
will be filled with rings of concentric circles, representing the range
of minima from the original threshold level down to zero.

Alternatively, the bubbles can be colored by the polar angle of the
iterate, as in the standard Fractint decomposition method.  Here, the
disks become filled with radial lines of color, emminating from the
center of the disk.

The formulas "bubbleboth" (Mandelbrot and Julia variations) combine
the concentric circle and ray colorings.  The magnitude of the final
minimum is scaled into an angle.  This is averaged with the polar angle
of the final iterate, using user-supplied weights.  This allows the
specification of either circles or rays using the same formula.  In
between (for example, using equal amounts of circle and ray) are swirls.
A judicious choice of color map will eliminate the branch cuts that can
be seen with the swirls.

Nature...

I visited your page....and I LOVED your Ode to Fractint.....(and the Nazi

been fractaling ever since ....just in case.

Here's something that appeared today....I always wonder where these things

I'm up to "c" in those never-ending formula files and I just noticed this
is another of Noel's great formulas. Thanks Noel!!!

I agree very much.  Especially since most of the groups I subscribe to to
learn things, things that I don't know;  the only knowledge I have to share
is usually off-topic, so I give it when people ask for it, or when it might
be useful.  (And why is it called Locke's Hair Syndrome?)

It's not bold or likely to strike fear in men's hearts, but it has the
general shape to it... (I think it might be really bad--it's old, from way
back when I was still using my MSN address publicly)

Subject: (fractint) Explanation, formula, and par file--nearline method (long)
Date: 18 Jan 1998 22:48:07 -0700 (MST)

Here is a coloring scheme that I developed.  Included are formula files,
parameters, and a much too long narrative.  The formulas are
annotated to help explain what is happening, and what parameters
should be used.  Happy reading.

Near to a given line

This method (also called, "nearline") is an extension of Fractint's
bof60 scheme.  In bof60, the question is asked, "how close does the
orbit come to the origin?", or, "what is the minimum magnitude of the
iterate?"  In nearline, we are curious about approach to a given line,
instead of the origin [the origin is the point 0+0i in the complex
plane, also written (0,0)].  The lines in question are all straight and
pass through the origin, so they have the equation, y=kx.  The slope of
the line, k, is equal tan(theta), where theta is the angle of the line
with respect to the x-axis.  Given that tan = sin/cos, an alternative
way to write the equation of the line is to define a distance quantity,
r, and set r equal to 0:

r = cos(theta) * y - sin(theta) * x = 0.

So the basis of this coloring method is, for a given theta, what is the
minimum value of |r|?

Given a minimum value of |r| for the orbit, the formulas plot the results
by taking the log of |r|, and using that as the polar angle of z for the
decomposition coloring.  This has the advantage of being able to handle a
wide range of values without rescaling, and compressing them into a small
variable space.  Decomposition wraps automatically, so no clipping is
encountered if the color overruns the 0 - 255 index range.  And, the log
function is only executed once per orbit, so the time penalty is minimal.

The general nature of this coloring is a series of lines, starting at the
fractal boundary and heading to infinity, asymptotic to the angle theta.
How these lines interact and intersect varies greatly with the choice of
theta.  Specifically, it is not clear what values of theta to choose to
cause the lines to intersect at the origin.  However, the lines can be
chosen in terms of iterations instead of angle.  The first iterate of (0,0)
is simply c, so, from the above equation, we can force the lines to cross
at the origin after 1 iteration by making

r = imag(c) * x - real(c) * y,

and clearly, r will be 0 at the origin at the first iteration.
Similarly, if we define

zero2 = c*c + c
      = the second iterate of (0,0), and

zero3 = zero2*zero2 + c
      = the third iterate of (0,0), then

r = imag(zero2) * x - real(zero2) * y

will cause an intersection at the second iteration, and

r = imag(zero3) * x - real(zero3) * y

will cause an intersection at the third iteration.  These techniques
are employed in nearline01_jul, -02_jul, and -03_jul, respectively.
Such actions are not required for the Mandelbrot variation, since the
origin is a fixed point, and all its iterates are zero.

While initially an external coloring scheme, this method works for
the inside as well.  Fundamentally, there's no difference between the
fractal interior and exterior with this method, so the formulas force
all iterations to escape, allowing interior points to be rendered via
decomposition, instead of relying on "inside=zmag".

It seems to be that a fractal image at 300dpi printed on an 8+1/2x11 sheet
of paper would be 2550 by 3300 at maximal size.

Because of this, I usually only use the D&C stuff to generate a 3200x2400
image in four 1600x1200 parts.

Hi Fractintiers,

And now presenting another fractal exploration by Dr. J, the mad
scientist.  See http://home.san.rr.com/jayrhill/Story/Story.html

Tonight, he has ventured into the deep dark fractal jungle, after dark of
course,
and again found more than he expected.

It is called Fractal of the Night (Elephant).

Will Dr. J regret not bringing his rain coat along this time?  Luck for us, he
has
his camera. To see what he has confronted, point your browser to

http://home.san.rr.com/jayrhill//FotN/FotN18.html

Enjoy,

Jason,

Glad you liked my page. I tried to make it simple, yet elegant. Try to
anyways.

It was a while back when I did that I cannot truly remember how I did it.
But I remember changing the water levels. I believe the colors has something
to do with it also. Try different colors and see what you come up with.
I haven't had any chance to make more 3D images, but I will in the future.
Thanx for reminding me!!...^_^

I had the same problem with my computer. I eventually traced it to an
on-screen clock TSR which I had in my AUTOEXEC.BAT file - it kept the
current time on screen as long as you were in a text mode. I think it must
have been confusing FRACTINT's clever graphics routines. Anyway, I removed
it and I don't have that problem now. If anyone else out there is having
the same problem but can't stand to live without their clock, a clock which
does work with FRACTINT (at least on my computer) is available from my
website:

I have an Epson Stylus Color 600 inkjet printer, and use it to produce
8.5x11 limited edition fractal image prints (for those images where the
4-color inks of the Epson can handle the RGB colors).  Since it is a 720 dpi
printer, I find what works great is a 7x7 array of 1024x768 for a total size
of 7168x5376.  Sometimes I take my 18432x13824 images and resample using
Mitchell anti-aliasing to the final resolution (thanks Rich!)

The results are outstanding for an inkjet output.  I found a place in town
which does high-quality lamination using a new Dupont film which is ultra-
crystal clear and smooth, and I totally seal the prints using it.  I prefer
this over spray since it is much more permanent, and significantly brightens
the colors of the inkjet, bringing out almost a 3-D like effect.  Of course
I individually number my prints with the inkjet itself, for a truly custom
limited edition print which I am beginning to market.

Of course, this doesn't compare at all to a fine Cibachrome print which I
talked about in a prior post.

Just my $0.02 worth.

I believe hitting F6 before win95 has a chance to load will bring you into
a screen where you can choose to load dos.

Is anybody here working on a Win32 specific version of FractInit?  I would
be very interested if they are, and would like to help some if possible or
needed.  I can't really use the DOS version under Windows NT, the only
display modes that work are the standard EGA/VGA modes.

This is a hearty thankyou to Tim Wegner for spending his valuable time
moderating this list as well as for his generous contributions to
Fractint itself.

It is also a thankyou to a number of gifted and experienced fractaliers
who share their insights and experience with the rest of us, so that we
may enjoy one of their and our hobbies.

 They have had a lot to say that is worthwhile in regard to several
topic threads that are ongoing and are very helpful and patient in
answering the on-topic questions of newbies and others that have a lot
to learn -- like me!

Off-topic discussions are time-consuming diversions, from which the
80-some subscribers to this list (or whatever the number is now) have
for the most part abstained.  I support Tim in his request that
off-topic discussion be carried on off this list and hope all others on
the list will too.  Some off-topicness is bound to occur, but we can all
try to respect the interests of the bulk of the subscribers who have
come into the list thus far by understanding and accepting the 'rules'
of the list.

Happy fractaling to all and may we all advance in our enjoyment and
mastery of the art and science of fractals.

There are two major issues when dealing with printing fractals:

    1. computing the image to best exploit the printer's resolution
    2. matching the colors to the printer's color space

#1 is best achieved by computing the dimensions like this:

    (image width in inches) x (horizontal dpi) = final pixel width
     (image height in inches) x (vertical dpi) = final pixel height

    If you want to anti-alias your image for the printer (recommended),
    then select your oversampling factor.  3 is a recommended minimum,
    4 for you really anal-retentive types.  Multiply the final pixel
    dimensions by the oversampling factor and this is the size of your
    aliased image.  Then take a filtering tool and filter down the
    aliased image to your final pixel size and print.  To give a more
    concrete example, suppose I have a 400dpi color printer that has an
    imaging area of 8x10.5" on the page (8.5x11 with 1/4" margins on
    each side) and I'm anal-retentive in my image quality so I select
    an oversampling factor of 4x:

    (8 in) x (400 dots/in) x 4 = 12,800 pixels
    (10.5 in) x (400 dots/in) x 4 = 16,800 pixels

    So I compute the image at 12,800x16,800 pixels (use fractint's 'b'
    command in order to get the image computed as tiles and then
    stitched together into one big image).

    Then I use a filtering program to filter the image down to its
    final size to ameliorate any aliasing present in the source
    image.  (And no, just having a high dpi does NOT eliminate
    aliasing; you will always need to anti-alias fractals for the best
    results.)  If you can get your images into non-interlaced PNG
    format, you can use Paul Heckbert's zoom program, which has been
    ported as a Win32 console application
    <URL: ftp://ftp.xmission.com/pub/users/l/legalize/misc/zoom.zip>
    If you use this program, I recommend the mitchell filter with a
    command-line something like:

    zoom -src src.png -dst dst.png -d 0 0 W H -filt mitchell

    Where WxH are the final dimensions you want the destination image
    to have.  If you want an indication of its progress as it
    computes add "-debug 1" to the command line.

#2 is much harder!

    The problem is that an RGB monitor can display many more colors
    than are representable by most printers.  However, if your
    fractals are "abstract", you may not care so much if your greens
    aren't as green on the print as they appear on the screen.
    However, if you have spent much time carefully selecting the
    colors, you will probably be bothered by shifts in the hues and
    so-on.  The best thing to do is to work iteratively with your
    printer (either the device, or the people at the service bureau
    you are using for a traditional 4-color process).  The worst
    offendor for color matching are the fully-saturated RGB colors.
    These are the colors at the edge of the color gamut of the CRT and
    the hardest to reproduce inside the color gamut of inks.  If you
    desaturate your colors -- keeping the hue and "whiteness" the
    same, but reducing the saturation -- you will bring the colors
    more within the gamut of the output device.  The same problem
    arises in converting RGB to NTSC for video.  NTSC has poor color
    resolution compared to RGB monitors.  In the HSV color model, I
    found a saturation of 85% worked well for the prints I made.
    However, note that a traditional CMYK 4-color process is going to
    have a hard time representing subtle shades of green and other
    colors that are combinations of the CMYK inks.

Friends,

   Just a reminder - I noted today two "langolier" formulas posted, an
original and a generalized version of the same. Revising and generalizing
existing formulas is a time honored practice among us.

   BUT please, the generalized formula (or any other variation which
produces, in effect, a different formula) should be given a different name
than the original (e.g Langolier2), so that the two formulas can be
distinguished by Fractint. Otherwise, confusion may result down the road
when someone refers to the formula, or the formula is called for in a .par
file.

While BMP and TIFF are both lossless formats with compression; PNG is
a lossless format with superior compression to both BMP and TIFF.  PNG
also has support for proper gamma correction, better interlacing than
GIF (for improved incremental display when transmitted over a network),
as well as alpha channel support.  Alpha channels bring a whole new
dimension to image manipulation and I look forward to alpha channel
support in fractint (someday) and the resulting fractal creations it
will bring.  PNG is also free of the Lempel-Zev/Unisys patent problem,
which requires programs to pay a royalty in order to use the patent,
such as with GIF.  (TIFF also uses Lempel-Zev compression and may be
affected by this patent, I'm not sure.)

John Noring wrote:

Before anyone gets scared, Tim has stated that fractint will continue
to read GIF files, just that the output format will be PNG in
anticipation of truecolor renderings, among other things.

Paul Derbyshire wrote:

TIFF can store a large variety of images, including bitmaps,
grayscale, 256-color palette based images, 24-bit truecolor images,
24-bit truecolor with alpha channel and even JPEG inside a TIFF.  TIFF
is very versatile, but all those options add up to programming
complexity.  TIFF isn't lossy unless you use the JPEG-inside-a-TIFF
variant (and this is lossy because of JPEG, not TIFF).  BMP does have
a compression scheme, but the compression scheme is not nearly as
efficient as PNG, or even TIFF.

As was already noted, because the fractint parameter block isn't
passed along in the PNG from the GIF, you lose the ability to load the
image into fractint and have the fractal parameters set when you save
the image as PNG in this way.  When fractint supports reading/writing
PNG files directly, you should be able to convert your GIF files to
PNG in a similar manner as you describe but retain the fractal
parameters block.

It is my understanding that both the current release of Netscrape and
Internet Exploder can display PNG files.

JPEG was designed for a very specific task: storing still images
captured from real-world sources such as cameras and image scanners.
For that subject matter, it works well.  It is a poor format for
figures, line drawings and clip-art because the prominence of sharp
edges in the images give the JPEG representation a hard time.  It can
work well for fractals, but not all of them.  Many fractals have a
preponderence of sharp edges, the case for which JPEG is least
suited.

Paul,

 - Maybe because tiff is restricted to truecolor and lossy like JPEG

TIFF images can be stored in a variety of ways (much to the annoyance of
those who must write TIFF software).  They can be uncompressed, poorly
compressed, decently compressed, or lossy compressed, depending on the
software you use.

  Hit Start/Shut down, and choose "Restart in DOS mode." That normally works
well enough for my DOS programs. Fractint seems to run fine through Win95 for

IMHO, it is the fully-saturated red, green and blue which are the problem.
The ink colors are Yellow, Magenta and Cyan (approximately).  Therefore,
these as fully-saturated colors in your image should come out just fine.
There would be no ink mixing which produces in ink jet printers a color
subtraction making the colors darker, muddier, less clear.
Thus, Yellow and Cyan mix to get Green, a darker green than we
see on the monitor. Now if there is true dithering in the print so
the inks don't mix but their colors add, you get a lighter Green with
less saturation, more nearly white.  If you like bright colors use lots of
yellow, cyan and magenta. These come through with the pure bright ink.

In the below image, I have used a less saturated darker red, bright cyan
and yellow, all of which should not be a problem.

Subject: (fractint) generalizing coloring methods
Date: 19 Jan 1998 11:52:54 -0700

In anticipation of 24-bit (and 32-bit) rendering modes in fractint,
I've been wondering if there isn't a way to unify all the various
coloring tricks embedded in FRMs as well as fractint's internal
coloring algorithms.  Here is what I have been thinking... if we
define a coloring "formula" and apply it to the iteration.  Here is
the proposed anatomy of a coloring formula:

    name {
    initialization :
    per-iteration
    finalization
    }

name        The name of this coloring method

initialization    Similar to the initialization section for a formula;
        "pixel" and other magic variables are initialized so
        they can be used by the coloring formula.  The
        coloring formula can introduce its own variables and
        initialize them here.

per-iteration    For coloring methods where the variables must be
        updated every iteration, change that information in
        this section

finalization    After the orbit has finished (because it bailed out,
        or reached maxiter, or hit a period cycle, etc.), this
        section assigns the pixel's color value

Here are some examples of the builtin coloring methods fractint has:

    iter {
    index = 0 :
    index++,
    color=colormap[index]
    }

    epsilon_cross {
    axis = 0, index = 0 :
    if (!axis && (imag(z) < .01)) then
       axis = 1
    else if (!axis && (real(z) < .01)) then
       axis = 2
    endif
    index++,
    if (axis == 1) then
       color = green
    else if (axis == 2) then
       color = yellow
    else
       color = colormap[index]
    endif
    }

In the epsilon_cross case, you might want to be able to have a way to
terminate the orbit early when you detect it nearing the axis.  A new
syntax could be introduced to allow the coloring scheme to affect
the bailout, or there could be a statement that aborted the iteration
because of the coloring test.

I think this kind of scheme encompasses all the existing coloring
modes of fractint and also covers the kinds of balls/stalks/etc. types
of colorings that others have embedded into their formulas.  The nice
thing about this kind of approach is that it separates the formulas
from the coloring.  Want a fancy colored M-set?  No need to avoid the
builtin type=mandel then, just specify the fancy coloring.

What do others think of this idea?  Are there coloring schemes that
DON'T fit into this framework?  I'd like to get something that is as
general as possible before doing any work on writing fractint code to
support it.

Sadly, this is not the case!!  The yellow of the inks is not the same
(photometrically speaking) yellow as that shown on your monitor.
Trust me, you really need to work with your Printer (the person, not
the device) or someone who is familiar with color matching in desktop
publishing in order to get your colors reproduced faithfully.  Its not
a simple matter of "cyan is cyan is cyan"....  For instance, the yellow
on your computer monitor is formed by adding the phosphorescent output
of the two additive primaries in your CRT (red and green).  However,
the yellow from the inks is formed by taking essentially white light
and subtracting everything but the yellow.  An entirely different
process of producing color, so it shouldn't come as a surprise that
the two "yellows" are not identicle.

Steve...

Bob and I sort of figured it out.....it's not a "true" gamma correction in
that only a portion of the palette is affected.  What apparently happens
is...if you select a "gamma" value of other than the default 1 (hit m while
looking at the palette), you will get a different series of color "steps"
for those colors which you are transitioning by using the = feature.  Thus,
a gamma value of, say 2.5, will produce a more tinted (lighter) set of
steps....and a value of less than 1 will produce a toned or darker
progression of colors.  Quite a handy little feature. It's best to try this
feature out with a color map that you are very familiar with and that has a
goodly number of color transitions rather than a map with one or two
transitions.

Hi, Blake

>I had windows95 running... does that count as a TSR? Oh,
well. There's only
>one word needed: Microsoft. Does anybody know how to get a
pure dos boot on
>a w95 machine?

The best way I found...there are a few, is to root out your
old DOS6.22 disks, and use them to create an optimum boot up
disk...for me this is a much easier way to boot purely in
DOS.
I have found that DOS 7 doesnt actually work very well as
far as memory management goes, so I created a 6.22 biit disk
with the following files.....

SYSTEM FILES:

io.sys                        These are the files which the
sys command will place
msdos.sys                  on the disk.
command.com


OTHER FILES
autoexec.bat                You will have to write this to
suit your own system.
chkstate.sys                needed by the memmaker program.
config.sys                    Again...write this to suit
your system.
defrag.exe                   ONLY use this if your disk was
format under 622 or less
                                  DO NOT USE if the disk was
format by win95
                                  YOU HAVE BEEN WARNED!!!
drvspace.bin                Only needed if you use disk
compression.
edit.com                      Very useful for editing your
autoexec and config files.
emm386.exe                For EMS compatibility.
himem.sys                   For XMS compatibility...emm386
wont work without it.
mem.exe                     Essential for checking what is
using memory, and where it is.
memmaker.exe             Handy utility which supposedly
gives optimal memory configuration
                                    I have always found it
better to do it by hand, but then I'm strange.
mouse.com                  Or whatever your mouse driver
program is called.
mscdex.exe                 Driver for CD-ROM drive (well
kinda anway)
qbasic.exe                   Drives edit.com
scandisk.exe                For checking drives.
sizer.exe                     Needed by the memmaker
program.
vide-cdd.sys                This is what my CD-ROM driver is
called...yours might be called
                                  something else...consult
the docs that came with your CD-ROM
                                  drive

Thats about it...

This setup can read and write to any HDs Ive ever come
accross.
I Actually have a folder on my HD called DOS622 which
contains all the DOS622 files.
I boot with this disk, and can then use any DOS622 commands
I like.  It is much easier than trying to use the buggy,
totally undocumented, incomplete DOS7 which comes with
win95.


        Have fun....
            Stephen

If you feel really compelled to have DOS as a full-blown OS availible to
you, you can partition a hard drive and use a multiple-booter like System
Commander, or better still, install Linux on yet another partition and
use something called LILO to boot all three; consult the Linux HOWTOs for
an exact explanation of this. Try
ftp://dagobah.stwing.upenn.edu/pub/mirrors/redhat/updates/HOWTO for the
gory details; you'll get to try XFractint as well this way...

    Thanks a lot, everybody. :) The dos boot solves my problems... even with
DOS7. I was going to use a dual-boot config of Win95/Linux, but my [ancient]
Aptiva motherboard doesn't agree with it. *sigh* That made me mad, because,
very frankly, Linux is much better than anything that Microsoft has ever

Hi Rich,

As one who fell for your trap, it is really be no surprise! Your
quote says it all. We are stimulated and respond - choosing Steven.
You see, there is a subliminal suggestion, no a command! We just
can't help it.  ;-)

Now the topic.  Folks, what is with the sea-horses in this image?
I have noticed in some iteration fractals that use bof60, we have
some inside regions which are spotted and some that are not. In
this example, the coral is all one color while the sea-horses cycle
through many. You will notice that the sea-horses are an anomaly
to the MSet.  This formula is only very slightly off from the classic
MSet.  Anyway, the anomaly allows some interesting pictures.

Jay

Hmmm. Might be your graphics card, then. Have you tried running fractint

You can always boot from an old DOS floppy by powering up your machine wi=
th
the DOS set-up disk in the floppy drive. Most machines boot in the sequen=

A: then C: (if not you can always configure the boot sequence from your

Date: 19 Jan 1998 17:13:32 -0500

    I have written a random map generator... I like being able to control
the bands of color more intuitively than you can with the built in
randomizer, and I didn't like Mapper, the generator that comes with
Fracxtra, so I wrote one that I hope to add more features to. Currently, it:
    * has greyscale or full color options
    * has banding from the color to white (the banding is my least
        favorite part of it, actually, because it always ends up
        with 255 255 255--perfect white.)
    * allows you to choose a black or random background
You can get it directly (in zip form, ~32k) from
www.connectu.net/bhyde/randmap.zip or from the page
www.connectu.net/bhyde/frmg.htm. I will try to get a C translation ASAP, so
that it doesn't use so much unnecessary space. Also, if you want, I can get
the QuickBasic source... my email is in my sig.

(The current version number is 0.41, but I'll have 1.0 as soon as I can
figure out a way to work around the 255x3 bug.)

Some things I'd like to see in a "map maker":

    o Manipulate very large palettes, not limited to 256 colors
      (i.e. palettes with 4K, 8K or 16K entries)
    o Drag an image onto the map maker application:
    > If the image is palette-based image (GIF, 8-bit PNG, etc.),
        then extract the palette
    > If the image is 24-bit, popup dialog to:
        o extract all colors from image as a large palette
        o adjust quantization parameters (median cut, histogram, color
        cube, etc.) to select subset of colors in 24-bit image
    o Fractionally blend palettes:
    for (i = 0; i < 256; i++)
        out[i] = pal_a[i]*blend + pal_b[i]*(1.0 - blend)
    o Stretch / squeeze number of entries in the palette
    > Stretch by interpolation
    > Squeeze by filtering & quantization
    o Manipulations of palettes in HSV/HLS/etc. color spaces
    o Ramps, gradients, ribbons, etc., a la KPT
    o Alpha channel support!

I might be forgetting some stuff, but that should keep you busy for a
while :)

I doubt it, but it does have some rudimentary sound output capacity;
from the fractint help pages at spanky:
<URL: http://spanky.triumf.ca/www/fractint/sound_params.html>

SOUND=off|x|y|z

     We're all MUCH too busy to waste time with Fractint at work, and
     no doubt you are too, so "sound=off" is included only for use at
     home, to avoid waking the kids or your Significant Other, late at
     night. (By the way, didn't you tell yourself "just one more zoom
     on LambdaSine" an hour ago?) Suggestions for a "boss" hot-key will
     be cheerfully ignored, as this sucker is getting big enough
     without including a spreadsheet screen too.  The "sound=x/y/x"
     options are for the "attractor" fractals, like the Lorenz fractals
     - they play with the sound on your PC speaker as they are
     generating an image, based on the X or Y or Z co-ordinate they are
     displaying at the moment. At the moment, "sound=x" (or y or z)
     really doesn't work very well when using an integer algorithm -
     try it with the floating-point toggle set, instead.

     The scope of the sound command has been extended. You can now hear
     the sound of fractal orbits--just turn on sound from the command
     line or the [X] menu, fire up a fractal, and try the [O]rbits
     command. Use the orbitdelay=[nnn] command (also on the [X] menu)
     to dramatically alter the effect, which ranges from an unearthly
     scream to a series of discrete tones. Not recommended when people
     you have to live with are nearby! Remember, we don't promise that
     it will sound beautiful!

     You can also "hear" any image that Fractint can decode; turn on
     sound before using [R] to read in a GIF file. We have no idea if
     this feature is useful. It was inspired by the comments of an
     on-line friend who is blind. We solicit feedback and suggestions
     from anyone who finds these sound features interesting or useful.
     The orbitdelay command also affects the sound of decoding images.

HERTZ=nnn

     Adjusts the sound produced by the "sound=x/y/z" option. Limits on
     legal values have been removed in version 19.3. You are on your
     own!

ORBITSAVE=sound

     This option causes the hertz value played through the PC speaker
     with sound=x|y|z option to be written to a file "sound.txt" in the
     current directory.  Bill Jemison has made some intriguing music
     with this option.

> For that matter, does anyone

Probably what you heard was synthesized from so-called "1/f noise";
there is a nice bibliography of papers and articles about this at
<URL: http://linkage.rockefeller.edu/wli/1fnoise/>

Hope that helps.

Well, I did my duty and entered the room about 8:00pm Eastern time
but I was all alone :(
I've never tried a chat room before so perhaps I did something
wrong. Different rooms kept appearing and vanishing from the

"Jax rang the bell". Yipee. Waited about 5 mins and then tried another
room just to find out if I was doing things properly but then the
Fractal room disappeared. Didn't know how one properly leaves
such environs so I just split to another url. Frankly, the thing seems
like a rather inefficient and frustrating way to communicate.
Probably just me... fractals confused me the first time too
(still do, actually :)

Where did you hear the Factal music? Was it a downloadable midi, wav or some other file?

Cheers,

Carl.

  I just had a chance to hear some fractal-generated music. The stuff sounds
really cool. Kind of mystical. You probably won't hear any CDs of it, but it's
cool. Does anyone know if there's any chance that Fractint is going to be able
to generate fractal music in the near future? For that matter, does anyone
know HOW to generate fractal music?

Hi;
I saw in an earlier posting that you were loading colormaps from  "E" + "L"
instead of the "C" + "L".
As I recall I got some leftover garbage on the screen from using "E" + "L".
I hope that helps...Jim

I've got some super fractal music at my site at http://www.dorsai.org/~arch.
It is written in the shareware program Art Song in MIDI format, then
sequenced in Orchestrator Plus and/or Cakewalk. It is wholly based on
fractal data (RGB values) derived from fractals drawn in Fractint.

Jack...

Actually it's a pretty good way to communicate with the right
software.......I prefer mirc or pirch to a browser.  If you have irc
software...you can be notified when someone you want to talk to shows up
rather than having to hang in a room....it's great for real-time help with
programs that run under windows and transferring large files back and forth.

The down-side is the one you ran into....people have to be on the net at
the same time.....when we get Fractint that runs under win95 and NT, we can
run a chat program as an ap while we wait for our fractals to materialize.
I noticed from the Fractint wish list that the thing most folks want is a
fully featured Fractint which is stable under NT.

SHORT TERM WISH LIST ITEM  .....a way to compare color maps, overwrite
existing color map names, comment the maps (similar to the comments in the
pars) and select them for deletion.

F.O.T.N. (Fractal of the Night) 19 Jan 1998 (Potatoe)

Tonight's fractal, discovered near last night's Elephant, looks a
lot like a potato. It is from the MSet, corresponding to the map of
the Julia sets computed from a formula by Michael G. Wareman. This
comes from  one of the branches on the period 5 bud on the MSet
butt. Nearby midgets are more normal looking, but not all. I found
a second potato on another branch. You never know what you will
find, digging around in fractal land! The formula is

z = p1*(z2 + c)2/((z2 + c) + p2) + c

with p1 and p2 equal to 100.

Here are the Fractint parameter files.

Enjoy

Since I have joined this group, I have had mixed feelings about it.

Bad: there's a lot of traffic (on- and off-topic).
Good: there's *so* much free data!
Bad: I'm developing a case of fractal time compression like you
  wouldn't believe (then again, maybe you would).
Good: I'm cranking out lots of (IMHO) good images from other peoples'
  formulae!
Bad: my life's disappearing into a fractal black hole.

OT1 (off-topic #1): Howdy Don, didn't know you were on!

Thanks to Morgan L. Owens for his 1/16 astrophysical formula post.
Although I know the meaning of the formulae are seriously perverted
by plugging in complex numbers, I can't complain about the results.

Here are two .pars, one for the OT, the other purely gratuitous. Both
of these are done at critical points; for ap-102 (which reminds me of
"magnet" fractals I have seen/done) there are a whole lot of these
around p1=1.5

Paul asked me to post.....
*******************************
I think Kerry's extensions to the bubble method are very
ingenious, especially the swirls.  Seeing her formulas
finally got me to translate my bubble method into a
Fractint formula.  If anybody's interested in how I came
to develop the bubble method about 2 1/2 years ago, my
paper, "PSEUDO-3D RENDERING METHODS FOR FRACTALS IN THE
COMPLEX PLANE" which was published in the journal
_Computers & Graphics_, Vol. 20, No. 5, pp. 751-758, 1996
gives all the details.

Anyhow, here's the formula and 4 par files to try it with.
The par file bubsmnd2 is the same as bubsmnd1 except for the
value of real(p2) which was increased so that the bubbles,
instead of being tangent to each other, are squished together
(this also required some minor editing of the colormap).
I tried to make the formula as clear as possible.  I'll be
glad to answer any questions about it.

Four years ago this week, I purchased a combination PhotoJet Printer
Board for my LaserJet 4 and a PhotoJet Circuit Board for my computer. It
was manufactured by XLI Corp of North Billerica, Mass. It cost $895
before the added freight charge. The software I use is Picture
Publisher.

I still use PhotoJet today. It prints out in gray scale at 2400 dpi on
8.5 x 11 inch paper. The results of the output are stupendous. My
fractal images have a photolike quality to them in the printouts.

I don't know if the company is still around, since I haven't found the
need to contact them since I purchased the circuits boards.

Maybe! But the music doesn't come easy or fast. Thanks.

I downloaded the par files without difficulty and there was
no =3D problem.  It gives an error message for the colors
and then runs it in the Fractint default palette with an odd sort
of dithering, which I assumed is how the Truecolor is rendered
in the 256 color palette.  I have had some trouble with getting
pars into Fractint in general, so if anyone is getting something
different, please let me know.  Thanks, they are truly great
images.

Here's another coloring method that I've used.

Ghost

In the ghost coloring scheme, you can make the fractal appear or disappear
against a gradient background.  It is based on the iteration smoothing
routine of Linas Vepstas, and uses an adjustable parameter to determine
how prevalent the fractal appears.

The iteration smoothing technique works by letting the iterate go much
beyond the required escape radius of 4, and converting its geometric
growth into a real number.  When combined with the original iteration
number, the result is a real number that can be plotted continuously
with the decomposition (or outside=real) methods.  Here, the smoothed
iteration count is scaled and made the polar angle for the decomposition
coloring.

The backgrounds for these images are gradients (using smooth color maps),
running horizontally, vertically, or in rays from the origin (point 0+0i).
In the latter case, the background is simply the polar angle of the pixel,
which may or may not be centered on the screen, depending on the zoom of
the image.  In the former two cases, the gradients are dynamically set to
use the full color range irrespective of the pixel coordinates.  In any
case, the background is represented by an angle, for use with decomposition.

Given angles for both the iteration count and the background image, they
are combined using the "ghost" parameter.  The iteration angle is scaled
by "ghost" and added to the background angle.  When the ghost level is
set to zero, then only the background angle remains, and that is what is
shown in the image.  Increasing the ghost level results in the background
being subtly, then significantly, perturbed by the fractal.  The disturbance
starts with the highest iteration levels first (except that interior points
are assigned 0 iteration, to clarify the boundary), and propagates to the
lower iterations as the ghostliness is increased.  The effect on the image
is to see the background gradient smoothly displaced by the fractal, but
to not see the fractal directly.

The best uses of this scheme seems to be on Julia dust (non-connected)
fractals, in which there is lots of "empty" space for the background to
show through.

I'm also wondering about this. My colour-map loads go without a hitch, but
what I find is if Fractint is drawing an image (in full-screen mode of
course) and something else happens in one of my other active programs (I'm
often playing a music CD at the time) - THINGS happen. Like Fractint for
some reason becomes convinced that it has finished and stops, complete with
sound effect. Or sometimes it confines all its drawing to a thin band at
the top of the screen. Switching to a text mode screen (such as TAB) can
seriously mangle the image.

I could go on but I'm too depressed now...

Subject: (fractint) Faster formulae - pointers for optimisation requested.
Date: 20 Jan 1998 23:46:07 +1300

Lately I've been working on a number of related formulae (at last count
1080 but projected to rise a fair bit higher - I really do think formula
inclusion would be a great idea). Many of them are fairly grim, but they do
surprise me now and then.

The thing is, the expressions I'm writing tend to get a bit long-winded
(and one of my main objectives is to shorten them as much as possible) and
that slows them down. Even if I get them as short as I can I'll still be
wanting to tweak them for speed. Does anyone have any suggestions as to
what sort of things can be done to speed things up at the source level?
Does sqr(z) work any faster (or slower) than z*z, for example? Does
(0,1)*real work faster than flip(real)?

I already try to precompute as much as possible before entering the loop.
Another suggested extension to formulae: a section which is run through
once _per image_, where needed constants can be set up in advance, rather
than redoing them every orbit. It's a small thing but it would save
millions of ops. Or is this carried through by the parser already?

I'm nowhere near releasing a beta-test version of this collection, and I
don't want to prerelease too much for fear of old versions drifting about
out there. But here's one. If anyone can see any egregious blunders on my
part of any kind, please get in touch with me so's I can see about
correcting them.
(Actually, while I was checking this post before sending it, I found an
egregious blunder of my own: "bailout" being erroneously set. Fortunately
correcting it didn't change the image. See, I do make mistakes!)

There is a wonderful chapter called "Chaos in A Major" in
the book by A. K. Dewdney, "The Tinkertop Computer",
published by W. H. Freeman and Company, 1993 which gives a
very simple algorithm for producing Chaotic Music:

input x and a
repeat
    x<- x*(a-x)
   step<-int(12*x/a)
   tone<- int(220*exp(ln(2)*step/12)
   play tone
until keypressed

This is based on the Logistic equation, but I guess any
fractal algorithm could be used as long as the outcome was
scaled. So when a is above 3.57 you enter the chaotic
region.

I found it worked fine. 220 is middle A on the scale. Didn't
sound fine, but worked fine.

He then goes on to talk about refinements. A human touch to
make it less chaotic and more musical?

He gives the musical score for the Fuguette vegetarienne,
which I had transposed and performed by a group of good
musicians. It was recorded (with permission) on a CD I
co-authored a number of years ago on Chaos and Fractals for
secondary students. It had something, that's the best I can
say. But if you want music, I'd recommend almost any other
CD!

cheers,

They should be generated at the highest resolution you have.  At 1280x102=

the dithering is hardly detectable.  At 1600x1200, it looks like highcolo=

At resolutions lower than 1024x768, the dithering can be very annoying.
But once converted to PNG, even thumbnails are pleasing - I converted PNG=

Hi Roland,
Thanks for the heads up about black on blue. I use Netscape 3 in WinBlows 95
and Micro$oft Internet Explorer 3.  Looked OK - not great but OK there. I've
change both Jan 18 and 19 to lighter background.

Would you explain how Lost Head is M[4]?  Thanks for the remarks.
I guess you are saying that less connected is more 'artful' and connected
is more 'technical' - rigorous, restrained.  A student whom I tutored on a
fractal science fair project tried to use the Mandelbrot set to 'model'
most any shape. He would choose something to make a picture of, a
tree, galaxy, what ever.  As you can guess, he had great difficulty with
the connectivity constraint. Controlling the image was the big challenge.
But he surprised me a few times. Then, alas, he discovered
iterated systems IF and played with that a little. His project
turned out quite good.

To create art with fractal tools, we need, as completely as possible,
total freedom to change the image in directions we want.  That means
not only more parameters (the classic MSet has 5: c is 2, zoom factor
is 1, pan location is 2), but the parameters must be orthogonal and
scaled reasonably.  Orthogonal so changing x and y change different
things. Imagine flying a jet fighter using twisting knobs and reading
dials in volts controlling servos.

So when I create a Fractal of the Night, I am part explorer and part
creator. I know, if I want a Julia set with a certain pattern type, the I
need to dial in coordinates based on patterns in another coordinate
system - the associated Mandelbrot set.  There are other coordinate
systems which could be devised which would control the image in
yet other ways. As we get more experience with some of the new
formula presented recently, we will want to display parameterizations
of these as an aid to navigation in our image spaces.

A simple example is one where an artist is exploring Julia set like
images and finding star patterns. She wants more points which, when
we plot her Julia sets into a map (Mandelbrot set) we find the stars
she already has are very near centers of buds whose periods are the
number of points in the stars. So now dialing in any number is easy,
just write a new formula for the MSet and locate the buds.  Well that
is easier said than done if she wants 17 points and simple filaments.
Now we need to switch to yet another display showing only period
17 locations.

This all sounds a lot like a technician, not artists. But even an oil
and canvas artists has to have certain tools to get effects she wants.
As the tools we develop get easier to use, we can more easily return
to being artists.

Subject: (fractint) v19.6 troubles
Date: 20 Jan 1998 09:29:49 -0800

Since I heard the warning shot about the conversion to PNG,
I downloaded and am assessing v19.6 ( *remember folks, Web
browsers do NOT support PNG!* ).  I have thus far encountered
the following bugs:

1) After loading an image using the preview window option,
subsequent images (full screen or not) are shifted to the right,
starting at the left-hand edge of the previous, cropped image.
A similar problem existed (and may still exist - I haven't checked
yet) in v19.3 when loading .pars (the image is cropped to the
last preview window), but loading an image from its .gif file reliably
cleared the problem; this is no longer the case.

Why do I generate full-size images in preview mode?  As far as
I know it's the only way to produce images in aspect ratios other
than 4:3 (x/y), and 1:1 is very handy for excluding undesirable
image elements (zoom out on the 051597-002 .pars from my 1/17
post to see what I mean).

2) Until I resolve out the problems with v19.6, I am running it from
a subdirectory.  When I try to load certain .pars (.pars from the list,
including Carlson's, which require IF and ELSE support) from the
parent directory (where v19.3 still resides), I get a series of error
messages (some too fast to read) which indicate that the files
(forms/pars) can't be located/opened/loaded. This happens even
when I provide full paths (in the .par files) to the correct (.frm) files.

Any advice?  I would really appreciate a final, clean v19.6 before the
Fractint wizards eliminate .gif output.


Thanks, Bud

For what I know 24 bits BMP has no compression : it uses 3 bytes for each

RLE.

My experience is that neither Explorer 4 nor Nescape 4 support PNG, even

JPG is a good format for fractals (even with sharp edges) if you set to a
reasonable value the amount of loss (2 for Paintshop Pro, 95% for
Microsoft Photo Editor). It is more compact than PNG (in a ratio of 2
or better with my settings) and this is nice for web pages. Look at the
true color fractals p. 15 and 16 of my album.

Jean-Pierre,

 - Can you explain me what is alpha channel ?

An alpha channel is an extra grey-scale channel stored along with an image,
which indicates which areas of the image are transparent (alpha channel is
black) or opaque (alpha channel is white).  Alpha channels are usually
stored as 8-bit values, which means you have a nice smooth range of
partially-transparent values between black and white.  Because you have
control over transparency on a per-pixel basis, it is easy to make some
parts of an image partially transparent, while leaving others alone.

None of this matters for a single image, but when you start compositing
images--putting them on top of each other--this becomes a very nice trick.
The "Julia Amalgam" picture in my gallery was done almost entirely by
manipulating the alpha channels of six Julia sets.  Rather than use *color*
for the iteration bands, I assigned all iterations in an image the same
color, and varied the *transparency* of the image by iteration.  I made
each Julia a different color and layered them all on top of each other.
You can view the image here:

    http://www.geocities.com/~fractalus/gallery1/pic12.htm

This is a fairly simple example, and I was just playing around and learning
how to use alpha channels in fractals when I made this picture.  Other than
as an example of possibilities with alpha blending, it's not that great. :)

 - 256 colors BMP _may_ have a succinct compression format wich is RLE.

RLE is optional for BMPs, but it's not widely supported and it's uncommon
to see it used.  (Not unheard of, just uncommon.)  It's also fairly weak,
as compression techniques go.

 scaled. So when a is above 3.57 you enter the chaotic
 region. >>

  Hmm... I tried programming that algorithm in QBasic, but all I got was one
long tone. Not very chaotic. :-P ::Shrugs:: Maybe I programmed something
wrong. BTW, there's a parenthesis missing  on that line with the int and exp
and ln and stuff. I assume it's supposed to go at the end of the line, right?

I doubt that this has anything to do with your web site which
is probably working fine.  On all the images I have tried (5 or
6) it says "oops I couldn't understand the argument
colors = 000EHO<7>....." (quotes one line of color parameter)
(That one was from "Pahoehoe flowing")
Then if I hit enter it draws the image without problem in the
default palette.  It looks good in the higher resolutions and the
dithering effect is gone. I had the same problem with"Clouds Over
Shiprock" both from the web site and from Jay Hill's web site
(where he removed the =3D problems for that one and the Carlson
formulas.)
I have had persistent troubles with only a few of the .par and
.frm files over the past months and it  most often occurs with
the IF...ELSE formulas and seems separate from the =3D
problem.

On only certain pars I get a variety of odd error messages
often quoting the color palette, which looks ok when I look
at it. On some formulas it says "oops cannot understand the
argument " z = pixel" or whatever when it looks like a normal
part of the formula.  Lately I am getting an error message
on most of Paul Carlson's formulas.  The par will start ok,
hunt for the formula and then give a msg. that it cannot
access the .frm in its location.  The location is the same as
the rest of the formulas.
I had assumed that I was doing something wrong
because I am a total computer novice and was reluctant
to take up the list time with it, but I have followed all the
posts on this. You copy from { to } as .par or .frm.,
it puts it in the same directory as Fractint and most
of them work ok .
   I am going to get some help from someone who
understands the paths and directories better than I do
but it looks to me like they're all in the same place.

Exactly the same problem I ran into with Lee's image, and others. I
corrected it by editing the par in Notepad. I found that the end of the
line cited did not have a backslash. Also, make sure there are no double
spaced lines. I sometimes get them too, especially with Lee's postings.
When editing them out, one must take great care that nothing else is
deleted. Perhaps this is your problem too.

Thank you. As I said in the post, those are some of my earliest formulae
that were worth anything. I see that both of your pars use jul1-138; I find
this the most productive as well, though the others do have their features
as well. What intrigues me is how different they look when using integer
code instead of floating point (now tell me, is there anyone out there
whose machine is _still_ faster with integer arithmetic?). I guess it's
something to do with the division.

I took your ap-102 par and sort of fiddled with it a bit. Alright, about
the only thing I didn't change was the 1.4586. The result is below.

Let me preface this by saying that while I'm personally happy with

pushing folks to join CompuServe. (I do confess I find refering to
CompuServe as  "compu$erve" as hopelessly immature and banal, but
that's just my opinion :-))

CompuServe is moving to a Web view. Some of their facilities are
available to non-members, and some are not. At the moment, the
fractint files are publically viewable. (I am not all that familiar
with the web access to CompServe - I access it with an offline DOS
program).

Point your browser to:

http://www.csi.com/go_c.asp?PIN=GraphicsDev

Click on "preview this site for free". Then click on files,
and activate the pulldown list "choose a file section"
and select "fractint sources" or "fractint images".

You can also see message threads, but you can't post.

The reason I am mentioning this is that I was asked just today what
files are on CompuServe. Now you can find out directly.

True, but the latest beta versions of both Netscape and Internet

Try ftp://ftp.phoenix.net/pub/USERS/twegner/simplgif.zip

for a much improved version. Don't upload it anywhere, it's still

The encoder is rock solid but the decoder, while good, has a few

I think I tried just about everything.  I was using DOS 6.22 and
booting directly into DOS (at the time I had Windows 3.1 on the
machine).

Now here's the message that I tried to send in response to Kerry's
message about bubbles:

After almost a month I can finally send email to this list again!!!

[snip]

As far as I know, I developed the "bubble" method about 2 1/2 years ago.
I haven't translated the method into a Fractint formula because, as
originally developed, the method involved two passes over the image.
I haven't had a chance yet to try Kerry's formula, but I thought you
might be interested in how I came to develop the method.  This method,
as well as a couple others, is described in my paper, "PSEUDO-3D
RENDERING METHODS FOR FRACTALS IN THE COMPLEX PLANE" that was published
in the journal _Computers & Graphics_, Vol. 20, No. 5, pp. 751-758, 1996.
Here is a short excerpt from it:
BUBBLE METHOD
The Bubble Method is so named because it produces images which
consist of elements with a spherical appearance.  The method was
inspired by the illustration preceding Chapter 4 of Pickover[3]
which shows contours of the minimum absolute value of z for
points within the Mandelbrot set.  Because the contours end at
the edge of the Mandelbrot set, many of the contours in the
illustration are incomplete.  To see what the image would look
like if all the contours were complete, a program was written in
which the contours of the minumum absolute value of z were
plotted for all points, whether or not they were within the
Mandelbrot set.  This had the desired effect of completing the
contours but also filled the entire image with contours.  The
method described below was developed to eliminate unwanted
contours in the final image.

     Unlike the other methods described above, the Bubble Method
requires that the image be plotted in two passes, with the user
interacting with the program after the first pass.

     Colormap:  The colormap has one color range.

     Bailout Criteria:  Bailout occurs when  z  exceeds a
specified value.

     Color Computations:  The minimum value of  z  in the orbit
is saved as minz.  The colormap index is computed from:
pcolor = (F * minz) MOD numcolors.  The best value for F will
vary from image to image, but a good first guess is five times
numcolors.  The value of F should be such that most of the colors
occur within the bubbles without any color being repeated within
a bubble.  After the first pass is complete the image will have
no background color.  The entire image will consist of concentric
bands of color, many of which will need to be changed to the
background color in the final image to achieve the desired
effect.  To allow this, the program pauses after the first pass
and allows the user to select a pixel in the image using the
mouse pointer.  minz is computed for the selected pixel and the
entire image is replotted, this time using the background color
for any pixel with minz less than the selected pixel's minz.  The
resulting image may need to be edited with a palette editing
program to make the colors within each bubble span the range from
lightest to darkest.

3. C. A. Pickover, Computers, Pattern, Chaos and Beauty,
   St. Martin's Press, New York (1990).

I'll try and see what I can do to implement this in a Fractint
formula in the near future.

Hi Kathy,

Are you sure you used my copy of Lee's par file??  It has not
the missing \ problems.  Now you need to put the formula part
in a .frm file, the rest in a par file.  What I like to do as a quickie
is stick frm: in front of the formula.

frm:carr2821   ........

Then save the file as a par and let Fractint find the formula in the par file.

I changed (sorry Lee) the copy on my site so it has the frm: in it.
Just down load it with no =3D and so on.  Just save as a .par and
it should run.

I just ran it again - no problem.

Field

In the Mandelbrot set, field lines are roughly perpendicular to the
dwell bands (bands of constant escape iteration number).  The lines
are not directly related to the iteration level, nor to the
decomposition rays, but are associated with the behavior of the orbits
as the iterates approach infinity.  Field lines of period "n" separate
the period n disks from the main cardioid of the Mandelbrot set.  The
points that make up these lines have the characteristic that, as the
magnitude of the orbit approaches infinity, the polar angle is

fieldangle = 2 * pi * m / (2^n - 1),

where n is the period of the line, and m = (1, 2, ... 2^n-1) is the
order of the line.

For example, there are 3 period 2 field lines, for m = 1, 2, and 3.
(The m=3 case is simply the positive real axis, whose fieldangle is
always 0.)  For m=1, the fieldangle = 2/3 pi radians, or 120 degrees.
Each successive iteration squares the previous iterate (neglecting
adding c, since c is very small relative to the iterate), which doubles
the fieldangle.  Twice 120 degrees is 240 degrees, or 4/3 pi radians.
Twice that is 8/3 pi radians, or 2/3 pi radians (since 6/3 pi radian
or 2 pi is a full circle).  So, the field line has the same angle again
in 2 iterations, or is periodic with period n=2.  The same thing happens
with the m=2 line.

Finding the field lines directly is not an easy task.  What this coloring
method does is to show approximations to the field lines, and show some
cases that aren't field lines at all.  It does this by computing the
polar angle of the iterate at each step, and comparing it to the angle
for the user-specified field line.  By coloring according to the smallest
error in angles (current vs. field line), lines are drawn that come close
to the specified field line.  (For the actual field line, the error would
be zero.)  However, many other lines have polar angles equal to that of
the specified field line, so they show up as well.  The result is not
necessarily a mathematically accurate illustration of the Mandelbrot
field lines, but it is another interesting way to render the set.

Gauss

In the Fractint method bof60, the question of interest is how close
the orbit comes to the origin (0+0i).  The origin is one of an infinity
of "Gaussian integers."  These are complex numbers such that both the
real and imaginary parts are integers.  Examples are:  (0,0), (-2,3),
(17,-5), and (1000000,123456789).  The gaussian scheme is concerned with
how close the orbit comes to a Gaussian integer.

To find the gaussian integer which the orbit most closely approaches,
the built-in function round() is used.  Round(zc) returns a complex
number whose components are the rounded components of zc.  This is a
Gaussian integer.  The distance from zc to round(zc) is simply the
magnitude of zc - round(zc).  The gaussian method tracks this distance
and records the value of zc for which the distance is the smallest.
This value of zc is zmin.

In the gaussintt methods (Julia and Mandelbrot variations), simply plots
the polar angle of zmin, by assigning zmin to z and using the decomp
coloring.  Since zmin can occur at any point in the orbit, there's no
clear connection between the pixel value and the resulting color.
However, nearby points can often have similar orbits, so the spots of
constant color (polar angle) can have a variety of sizes.  Similar
results are obtained with the gaussintr methods.  Here, the log of the
magnitude of zmin is used as the polar angle for decomposition.

For particular combinations of parameter c and initial zc, the orbit
may be all Gaussian integers, for example, starting with zc=1 and c =
(0,1).  For other combinations of zc and c, such as zc=0 and c=pi,
the orbit will never be an integer.  Thus, it is reasonable to assume
that some orbits will tend to be closer to integers than others.  This
is illustrated with the gaussinttot methods.  A running sum of the
distances, r, is kept for all iterations in the orbit.  The mean
distance is then determined, and this is scaled into the decomposition
angle.  The result is a grid-like pattern superimposed on the basic
fractal structure.

Also true, but until everyone that uses the two "big boys" decides to
upgrade to the most current versions, they can use the plugin and view
PNG files online.  Support for PNG is there in the latest levels (which
I have and use), but I still prefer to use my Navigator 3.04 Gold.

Just thought I would pass on a helpful hint for individuals not using
the "bleeding edge" software.

Actually plugins are support, just a secondary or subordinate role to a
leading performer.  They aid the cause, policy, or interests of
software; providing for or maintaining, by supplying necessities.  (See
dictionary under "support".)

Netscape's latest browser release level handles PNG file formats, but
how many individuals are currently using this level??  Until users of
Microsoft or Netscape browsers get them up to speed, plugins will give
them support for PNG files.

And what about the rest of the world that don't use either one of the
two "big boys" browsers???

All amigabrowsers can (or should) handle png. The system provides
Datatypes to load those. Every Programm able to handle the Picture
datatype handles png, gif, iff, tiff, bmp, ppm,... all the same way.

I think png is far better than gif, because its free, compresses
better and has 24 Bit.

May the Source be with you.

That was it!  They were double spaced.  I corrected that and the color
maps from Lee Skinner work fine, and at least some of the Paul Carlson
formulas work too.  I can't believe how many things I've fooled around
with in the last couple of months, and was beginning to have some....
..doubts....and the problem was they were double spaced!

Yes, I used your copy and I do understand the \ and saving
the .par and .frm.  It was the double space.  The odd thing
is a few of the double spaced ones worked.  Maybe only
certain things are sensitive to the double space issue.  This
was not actually wasted time for me because I learned a lot
repeatedly taking things apart and putting them back together.
Thanks again for putting them on your web site.

Okay, I think I'm ready to come out of the cave (still on Navigator 2.02).
If Paul, or anyone else, could provide input on Nav 3.xx vs 4.xx (to *my*
address, unless you think it would be of general interest) I would
appreciate it.  I'm not interested in company propoganda, but in real-life
experience with issues like configurability, compatability with plug-ins,
speed and ease of use for still images and motion video (the main
reason I've eliminated Mircodespot Exploiter from consideration) and
memory footprint (hard and volatile - this is I'm still on Win 3.1). One
of the reasons I am reluctant to use Nav 4.x is this goofy "office suite"
approach both of the majors are taking with regard to their browsers.
"I don't want a memory hogging office suite, dammit!"
What I *do* want is a fast, capable, robust browser.  Period.
So if 4.x can be stripped of the fat, that would be fine.

As to the issue of .gif output, my concern isn't with fractal addicts like
ourselves (who will put aside food, drink, sex, and fear of plug-in
installation to pursue our habit), it's with losing the general audience.
Most of the Web audience tend to throw up their hands and move on
when confronted with such obstacles, because plug-ins aren't exactly
plug-and-play.  I get about 30 visitors a day, and guess about 20 of
those would give up and move on.

Since I'm getting long-winded, I will finish with a bullet chart of issues:

- I could convert the PNG files to GIF, but 256 color renditions of 24 bit
 images are usually pretty ugly (an oxymoron?), and, if you've how most
 most image conversions organize the palette, completely uneditable.

- (256 color) GIF images are the only way to display images undithered on
 the Web (if Nav 4.x has 24 bit support, please set me straight on this).

- JPEG has the same problem as cited above.

And to the Fractint developers, a question: how much overhead would really
be required to retain GIF output capability and 256 color palette support?
(I know, you probably think I'm a Ludite... you're not the first.)


Thanks, Bud

P.S. - I have nothing against 24 bit color or good file compression.

Would people find it useful if we created a (moderated) list JUST for
the posting of formula files and PARs and web URLs?  I suggest it
still be kosher to include a par/frm when you're trying to use it to
illustrate a discussion point, or question, but perhaps if we had a
separate "announce" list for people to announce, distributue, share,
get pars/frms/URLs/etc., it might help segregate the traffic and bring
the discussion list back down to a smaller number of messages.  Just a
thought... let's hear what you think about the idea :)

Yes. An alternative might be to create a weekly or monthly digest, but
that's assuming we could find someone to donate several hours a week to
the task...

In article <[e-mail]> ,
    "J.P. Louvet" <[e-mail]>  writes:
> Can you explain me what is alpha channel ?

Damien covered it pretty nicely, but I'll add a little more info.
Think of an alpha channel as describing the opacity (or transparency,
if we think of opacity going from 0 to 1, with 1 being completely opaque
and 0 being completely transparent, then transparency = 1 - opacity)
of each pixel.  If alpha is stored just like any other pixel channel,
we typically use 8 bits for the alpha channel.  This gives a 32-bit
pixel, 8 bits each for red, green, blue, and alpha.

You can experiment with alpha in lots of paint programs like
photoshop.  They might call the alpha channel a "mask" or a
"transparency mask" or an "opacity mask", etc.  Alpha channels let you
do very interesting things when combining images.  When an image is
combined with another through an alpha channel, the alpha channel is
used as a blending factor:

    combination = image1 * alpha  + image2 * (1 - alpha)

Since alpha and 1-alpha represent two fractions that add up to one,
this computation keeps the image pixels inside the valid range (they
don't get smaller -- fading to black, or larger -- saturating to white).

Fun things you can do with alpha and fractals:

    o color normally, but use the value of the last iterate to
    determine the transparency
    o color normally and extract one of the red/green/blue channels to
    use as an alpha channel on another image
    o color several views of the same fractal and use alpha channel to
    combine them.  (Damien's example showed this, I think)

The "whitesq" fractint trick used in formulas can be thought of as
implementing a sort of transparency.  It essentially allows you to
interleave two fractals together, selecting one or the other based on
the value of whitesq.  Every other pixel then corresponds to one of
the two images interleaved toether.  Your eyeball averages together
the adjacent pixels and they appear to be blended together if you look
from a distance.  An alpha channel of 0.5 assigned to each separate
image and then both of them combined would achieve a similar effect.

This kind of transparency is called "screen door" transparency because
the two images being blended together appear as if enmeshed together
through a screen.  By varying the screen, you can get achieve
different levesl of blending between the two images.  (For instance,
take a pixel pattern of ABAABABAAB... that repeats to cover the screen
instead of the ABAB... repeating over the screen and you end up with
more of the "A" image than the "B" image appearing on the screen and
if things are done right, your eye will think you are viewing mostly
the A image with a fainter copy of B superimposed.

An alpha channel provides much better support (especially when you
consider fractint as just one program in an artist's toolbox) for
transparency.  It isn't much of an issue now, given that fractint
doesn't yet support a file format that handles alpha (GIF does not)
and doesn't yet support 24-bit rendering modes.  A palette-based
rendering can take advantage of alpha support under PNG (the colormap
entries can have an alpha associated with the color).  Alpha support
will be more important as fractint begins to encompass PNG and
truecolor rendering modes.

Thanks for the fix.  I can't believe I was so stubborn as not to try it.
(Then again, maybe I can.)  I may have redundant files on my system,
but they're relatively small.  I still consider it a bug, but it's one I can
live with.  My apologies to Stone Soup.  And I'm diggin' the new 19.6
capabilities.

That said, I'm still having trouble with bug #1.

Bud,

 - - (256 color) GIF images are the only way to display images undithered on
 -  the Web (if Nav 4.x has 24 bit support, please set me straight on this).

Uh, I've got Navigator 3 and 4, and IE 3 and 4... all show 24-bit images
undithered in 16-bit and 24-bit display modes.  If you're still in an 8-bit
(256-color) display mode, then it *must* dither the image... no choice.
But dithering is not required (or used) for higher color modes with these
browsers.  (Note: careful scrutiny of IE4 will show that it does dither
24-bit images in a 16-bit display mode, but the dithering is to reduce the
images to 16-bit color, not to 8-bit color.)

I would like this very much.  I really enjoy the pars, but would rather
download the separate list's last month's archive and spend an hour
once a month cutting and pasting, instead of every night.  The digest
idea suggested by Ian would work as well, if not better?

That is odd indeed! My first impulse was to say that none worked for me,
but then I remembered that after I had discovered this problem, I did not
even try to run any subsequently received double spaced pars; I edited
them immediately. I brought up the issue of double spaced lines some time
ago. Jay had the correct answer to the question why they occur, and the
recipe for prevention. On October 11, 1997 he wrote:

I have been following his advice to cut lines manually. Before I did so,
my own pars always got back to me double spaced; not once since then. I
would like to add that it is not always only the color part. I have seen
double spaced lines in connection with long center-mag (or corners)
specifications too.

I encourage you to do so, though admittedly I would not get to see them
until much later in the AM! I, for one, do not think that this list should
be limited to formulas and pars posted in order to illustrate some point
of discussion. Here, at any rate, is a pointless par.

  No, really, I'm not a Nazi. It's just weird to see stuff like that in

Subject: (fractint) The elusive Herman ring: Caught at last!
Date: 22 Jan 1998 00:20:36 -0500 (EST)


Anyone who's seriously read through some of the stuff in The Beauty of
Fractals or The Science of Fractal Images may have noticed that while
great attention is paid to Siegel disks, attractors and parabolic cycles
and points, there are also offhand mentions of something called Herman
rings, but with no details. One fact I gleaned was that a Herman ring did
have some characteristics of Siegel disks including an irrational rotation
of a point around an invariant curve; I had images of a sort of "Siegel
annulus" with no cycle at the center, or perhaps a curve within an
attracting basin. A few attempts I made at constructing a function that
would rotate the unit circle by a parameter alpha while displaying other
dynamics elsewhere failed.

On a hunch, I went into the university library the other day and ran a
computer search for "Herman ring"; no luck. I tried the more generic
subject "Complex mapping" which pointed me to an obscure Springer-Verlag
book a single copy of which was buried in the basement. When I went down
there, I eventually managed to find the book. (If you thought the Dewey
decimal system was bad, the crazy system Carleton uses is its square; not
only digits, but letters, digits, and more decimal digits. This one was
QA337.5 C37.) Its front cover was adorned with a rather plain image of a
simple quadratic Julia set. Inside the back cover was a well-fed index,
with 'Herman ring' figuring prominently under the H. The reference on page
46 turned out to state the Sullivan classification TBOF and TSOFI also
state, but a bit more mathematically. It pointed the reader interested in
Herman rings to the other Herman ring page, 106. There I found what I was
looking for: a whole wack of info, and an example function to iterate. The
rational function is alpha*z^2*(z-c)/(1-cz), produces some of the most
beautiful Julia sets I've ever seen, has attractors at 0 and infinity
always, two critical points of conjugate fate at 3+c^2 plus or minus
square root (9-10*c^2+c^4) all over 4c (plus zero and infinity), generates
very peculiar Mandelbrot images in the 4-dimensional space of c and alpha
(slices of fixed c and of fixed alpha look interesting), and lastly,
generates Herman rings. Attached below is hring.frm, with two versions of
the Julia sets, and the two slicings of the M-set. Below that is a PAR
file chock full of two days worth of exploration. Six distinct Herman ring
Julias are included, some with zooms, as well as Julias that are close to
being Herman rings and have cyclic attractors, others that have only A(0)
and A(oo) but a complex dendrite or Cantor dust approaching filling in the
ring, and all exotically gorgeous.

And it turns out a Herman ring is like a "Siegel annulus" or a Siegel disk
with ahole punched out. Generate one of the Herman rings in the PAR, then
use the orbits window to take a peek. Note how invariant curves near
either the inner or outer skin of the ring are very crinkled and fractal,
while those near the center are smoothish and near-circular.

The "interesting" areas of the Julia sets tend to be quite large, so
sometimes you want to zoom out from the default range after punching in
new parameters.

Perhaps the policy should be that a par is the price of an off-topic post
(though I suppose you could say it then becomes on-topic, which is OK).

I think a lot of the pars worked but none of

That would be very nice. I thought of this myself after dealing with some
tricky types with only a bunch of variable finite attractors. It'd be nice

Nature...

I visited your page....and I LOVED your Ode to Fractint.....(and the Nazi
Fractal, of course). Your poem said how I feel when I make fractals.  My
first really good Fractint fractal was a cross.... it materialized out of
the fractal void one week before easter last year.......scary.....and I've
been fractaling ever since ....just in case.

Here's something that appeared today....I always wonder where these things
come from

I'm up to "c" in those never-ending formula files and I just noticed this

Guy,

I can receive your mail, I just can't answer you directly. So you can
email attachments to me. Please don't post any messages with
attachments tgo the list.

Your previous example was a genuine bug in simplgfif. This time it
was the *decoder*. The no bugs have yet been discovered in the
encoder. At the moment I don't need mopre tests of simplgif. I will
make a new version with a new decoder. I'll use the same decoder that
Fractint uses.

Here's an interesting note. We have eliminated the 2048 in the
developer's version of fractint. Fractint can now do simplgif's job!
You just make an appropriate diskvideo mode, load the MIG, and save.
Of course with the developer's version, you can make a 4000x3000
pixel image directly, so you don't need the GIF approach.

One advantage of Fractint over simplgif is that it can use extended
memory for diskvideo, so the large temporary file is not made.

Subject: (fractint) Explanation, formula, and par file--nearline method (long)
Date: 18 Jan 1998 22:48:07 -0700 (MST)

Here is a coloring scheme that I developed.  Included are formula files,
parameters, and a much too long narrative.  The formulas are
annotated to help explain what is happening, and what parameters
should be used.  Happy reading.

Near to a given line

This method (also called, "nearline") is an extension of Fractint's
bof60 scheme.  In bof60, the question is asked, "how close does the
orbit come to the origin?", or, "what is the minimum magnitude of the
iterate?"  In nearline, we are curious about approach to a given line,
instead of the origin [the origin is the point 0+0i in the complex
plane, also written (0,0)].  The lines in question are all straight and
pass through the origin, so they have the equation, y=kx.  The slope of
the line, k, is equal tan(theta), where theta is the angle of the line
with respect to the x-axis.  Given that tan = sin/cos, an alternative
way to write the equation of the line is to define a distance quantity,
r, and set r equal to 0:

r = cos(theta) * y - sin(theta) * x = 0.

So the basis of this coloring method is, for a given theta, what is the
minimum value of |r|?

Given a minimum value of |r| for the orbit, the formulas plot the results
by taking the log of |r|, and using that as the polar angle of z for the
decomposition coloring.  This has the advantage of being able to handle a
wide range of values without rescaling, and compressing them into a small
variable space.  Decomposition wraps automatically, so no clipping is
encountered if the color overruns the 0 - 255 index range.  And, the log
function is only executed once per orbit, so the time penalty is minimal.

The general nature of this coloring is a series of lines, starting at the
fractal boundary and heading to infinity, asymptotic to the angle theta.
How these lines interact and intersect varies greatly with the choice of
theta.  Specifically, it is not clear what values of theta to choose to
cause the lines to intersect at the origin.  However, the lines can be
chosen in terms of iterations instead of angle.  The first iterate of (0,0)
is simply c, so, from the above equation, we can force the lines to cross
at the origin after 1 iteration by making

r = imag(c) * x - real(c) * y,

and clearly, r will be 0 at the origin at the first iteration.
Similarly, if we define

zero2 = c*c + c
      = the second iterate of (0,0), and

zero3 = zero2*zero2 + c
      = the third iterate of (0,0), then

r = imag(zero2) * x - real(zero2) * y

will cause an intersection at the second iteration, and

r = imag(zero3) * x - real(zero3) * y

will cause an intersection at the third iteration.  These techniques
are employed in nearline01_jul, -02_jul, and -03_jul, respectively.
Such actions are not required for the Mandelbrot variation, since the
origin is a fixed point, and all its iterates are zero.

While initially an external coloring scheme, this method works for
the inside as well.  Fundamentally, there's no difference between the
fractal interior and exterior with this method, so the formulas force
all iterations to escape, allowing interior points to be rendered via
decomposition, instead of relying on "inside=zmag".

Hmm... Let's see. If Carleton uses a system similar to Auckland University
the 337.5 is the Dewey classification (of course), 'C' is the initial of
the author, and the "37" is just there to make the entry unique. The QA has
me stumped, though. Is there more than one library on campus?

But what was the TITLE?? For that matter all I know of the author is that
the name begins with 'C'! From the hints about the layout of the index, it
sounds interesting.

To make this on-topic: what's needed is a way to display the computed
orbits _alone_, so that one doesn't have to sit with a finger hovering over
the 'O' key. And do this with any formula. I'm talking about a hybrid of
the formula type and the Mandelcloud (or dynamic) type.

It seems to be that a fractal image at 300dpi printed on an 8+1/2x11 sheet
of paper would be 2550 by 3300 at maximal size.

Because of this, I usually only use the D&C stuff to generate a 3200x2400
image in four 1600x1200 parts.

True, but the latest beta versions of both Netscape and Internet
Explorer support PNG instrinsically. For example, I am using Netscape
4.04, which I can verify does support PNG.

You are very lucky because the latest French version of Explorer
(downloaded yesterday) _does not_ support PNG : I am asked wether I will
record the file, wether I want to open it (with the defaut program I use

Subject: (fractint) Offline HTML Fractal Gallery
Date: 22 Jan 1998 18:53:31 -0000

Hi all,

    I have now finished the design of the OFFLINE HTML
FRACTAL GALLERY.  This is a project I thought of during the
contest, and was inspired by the offline viewer used during
the contest.

    The images will come as a PAR file...with a batch file
to generate them in fractint.

    I propose to allow anybody who wishes, to have up to 5
images in the gallery, all contributors will have a seperate
page with thumbnails, and these thumbs will be linked to
full size images.  I would ask that you give the images
meaninful names (ie NOT dmx_04_12a).  Please save the pars
with all colour info (not a link to a map) and give some
idea of the time taken to render (please avoid images that
take days).

    Anybody who is interested in having their images
included should send an Email to me
        [e-mail]
and not the list.  Preferably put all the pars into one file
and send it as an attachment, or if you can't manage
attachments (some people can't) placing them in the body of
the message will be fine.

I hope to have the first version available by Sunday, and
can be obtained by following the link for OFFLINE GALLERY at
my website.
    http://ireland.iol.ie/~bagpuss

    It will be available as a single ZIP file, and because
the images are rendered offline it will hopefully be fairly
small.  Anyone who does not have Web access can email me and
I will send the file to them as an attachment.


        Stephen

Subject: (fractint) Fractal of the Night, 21 Jan 1998 (Starfish)
Date: 22 Jan 1998 12:44:44 -0800


F.O.T.N. (Fractal of the Night) 21 Jan 1998 (Starfish)

And now presenting a first for Dr. J, the mad scientist.
Tonight, shocked by what he saw in his fractal mirror
last night (Big Fatso)

http://home.san.rr.com/jayrhill/FotN/FotN20.html

he decided to go for an evening walk down to the beach.
He soon arrived at the very edge of fractal land, where
the solid features become fractal dust or sand. Even in
the fading light, he thought for sure he saw something
interesting. It was so small he had to get out his pocket
Fractoscope(tm), a Fractint Model 19.6, to see it. Carefully
picking it up, he took it back to the lab for a better
look. Ah, a baby starfish!  He knew they were small,
but this one was less than a micron across.  You can see
its picture, shown as he saw it, by dialing in the
proper settings on your fractoscope.


The formula is Jim Muth's MandelbrotMix which iterates

g(z,c) = a z^b + d z^f + c

Jim was wondering about why certain forms show small MSet
midgets (usuall cardioid and buds) while others show higher
order shapes like z := z^3 +c. The effect comes about when
we use the critical point to start the iteration. That
is, z0 is a zero of this equation dg/dz = 0. For Muth's
formula, critical points are

z0=(-a*b/f/d)^(1/(f-b))

I decided to explore a mix of z^5 and z^6. Each of which
would produce 4 and 5 sided objects respectively.  Mixed
they produce distorted 5 sided objects when z0=0.  The
critical point for this example is -5/6 = -.83333333333.

Making image as a function of z0 show progressively more
distortion as z0 decreases passed -5/6. I pushed it until
the solid objects disappeared suddenly at about -1.42. In
fact tonight's picture is of a starfish near the last small
spec. The value of z0 has been pushed to -1.42237.

Here are the Fractint parameter files.

Enjoy
Jay

Hi Fractintiers,

And now presenting another fractal exploration by Dr. J, the mad
scientist.  See http://home.san.rr.com/jayrhill/Story/Story.html

Tonight, he has ventured into the deep dark fractal jungle, after dark of
course,
and again found more than he expected.

It is called Fractal of the Night (Elephant).

Will Dr. J regret not bringing his rain coat along this time?  Luck for us, he
has
his camera. To see what he has confronted, point your browser to

http://home.san.rr.com/jayrhill//FotN/FotN18.html

Enjoy,

Jean...

You Frenchmen must be very brave to download and actually use anything
supplied by Microsoft....especially for free.  I've had versions of
Explorer crash my win 95 twice (slow learner here)....but those were betas.
I was visiting some graphics sites today, and I'm not the only person who
believes that "support" for PNG means more than just allowing a plug in.
Most web users don't know from plug in......so if it isn't supplied as part
of the browser they won't be able to access that feature.  I like
PNG.....but I think we need to lobby Netscape to add viewing PNG format as
a "native" capability. I want casual surfers to see fractals as well as
this informed audience and I don't know that I'll have the patience to post
both gifs and pngs at my site.

I had the same problem with my computer. I eventually traced it to an
on-screen clock TSR which I had in my AUTOEXEC.BAT file - it kept the
current time on screen as long as you were in a text mode. I think it must
have been confusing FRACTINT's clever graphics routines. Anyway, I removed
it and I don't have that problem now. If anyone else out there is having
the same problem but can't stand to live without their clock, a clock which
does work with FRACTINT (at least on my computer) is available from my
website:

F.O.T.N. (Fractal of the Night) 22 Jan 1998 (Manta)

Having played with his starfish about as much as one can,
(Starfish) http://home.san.rr.com/jayrhill/FotN/FotN21.html
Dr. J, the mad scientist, decided he should put it back
where he found it.  Not a problem, since he had noted its
coordinates at the edge of fractal land the night before.
As he approached the beach, things just didn't look right.

Before he could figure out what the matter was, he found
himself neck deep in the sea. "Something awful is down here!"
he told himself.  On these matters he was usually correct.
Only the fact that the Manta was not hungry saved him from
becoming munchies for the giant Manta (see tonight's picture).
Finally back at the lab he discovered his nearly fatal error.
He had left the lab with the wrong formula loaded into
his Fractomap(tm). What you expect to find with one formula
most certainly will surprise you with another.

Yes, set your Fractomap to the formula by Michael G. Wareman.
Sometimes, you compute a Julia set, and find it is mostly solid
(the point in the corresponding MSet is slightly inside a
component). Some of these are pretty boring, a bunch of ripples
around the edge.  This happened with tonight's fractal. But when I
tried inverting it, I got something more to my liking.

Here are the Fractint parameter files.

Enjoy

Subject: (fractint) 3D glasses for Fractint viewing...so many to view
Date: 23 Jan 1998 01:25:56 -0800

Hi gang,

Did you know Fractint can make 3D images which you view with
those funky Red and Blue glasses?  Ever wonder where you
could get them for cheap?

I can get you as many as you want for just $4 per pair, er make
that per two pair (4 eyes worth). Now that is only $1 per eye!!
And as a bonus you can have 27 dazzling images of great
astronomical prints!  Does this sound like another SPAM from
Jay?  Well OK, I really don't want to have to go through a sales
pitch any more than you. Least of all, make deliveries.

So I won't!!  :-)

Just point your transportation device toward the nearest magazine
sales rack and get the March 1998 issue of Astronomy, $3.95.

BTW, we are getting some really great posts about advanced
formula writing.  I'm still hoping for lesson 101 showing the basic
MSet plot with these methods. I'm considering posting my
Fractal of the Night to the Fractal-Art list only. That should cut
down on the traffic some. I assume all you all subscribe to both.
In any case you can visit my web page for catch-up view.

It looks like my web page at home technique first introduced in
the contest is catching on. It could well become the future for
this list. The only problem is there are a few folk who are only
on email.

Frankly, I don't think a token par posted makes up for an off
topic post.  I made the off-hand remark earlier that we would
soon have our hard disks filled with off topic posts just for the
image pars. The good posts being long lost. This is indeed
coming to pass. We spend all evening snipping and pasting.
I am rapidly developing a real mess. Sometimes I think it
would be better for off-topic posts not have a par. Then I can
just delete it! and be done.

Before the contest we had about 500 posts in half a year.
The Fractal-Art folk threw us out just in time.  The contest
developed a thousand posts in two months (give or take).
Now it looks like a thousand so far in January. I will still try
to create the iFAQ, because out of a projected 10,000 posts
by the end of this year, there will be about 200 pages of
really top quality material.

Are we are seeing what I forecasted? Will you soon have to beg
folk to look at your images, compute your pars or try your formula?
Will we replace (c) which means don't copy with (p) which means
please look?

There are literally thousands of each, pars and formula. Jim
Muth has explored more than a thousand formula.

Not images, formula.

From just one formula, I posted pars for about 20,000 MSet
midgets earlier (to make this very point).  Don't forget,
there is at least one screen saver which automates viewing.
The problem is, live viewing is too slow. But when I run it with
the 20,000 midget files, I find I'm noting down the numbers of
about 20% because they are so cool. The MSet has unlimited
surprises.  But these must be called just average, by definition.

Even when you take into account the works of the really good
artists, the quantity is overwhelming.  There is a series of
Bob Margolis' images running on alt.binaries.pictures.fractals
which alone is near a thousand.  I think archives and collections
will soon require too much labor to view.

Perhaps some automatic version of my contest web pages
would help.  One should be able to get a segment, unzip it,
and run a batch construction file over night. Then in a few
minutes over coffee view the several hundred images
followed by blowing away the lot.

How else could you ever keep up??!!  Perhaps you can't.

Pleaaaase don't let this post dampen any spirits, I'm really
enjoying the flood. I actually view every par posted. I'm just
trying to invent another device to help us, like I did with the
contest.  So if anyone has a GOOD idea what to do with
all these fractals, let us know.

Then we will all know where to stick this one....

I think I have all the messages posted while I was gone (downloaded
archives), but if anyone sent me any personal messages Saturday or Sunday,
I think they were lost.

This is a test posting to see if I can post to the mailing list yet.  The
test post I made on Tuesday bounced back to me.

If this post makes it to ANYONE, please let me know!  Thanks!

Thanks for the super-kind words, Don!!!

I forgot to add that Netscape users won't be able to hear the opening midi
sequence (which I think is one of my better pieces.)
But, if you add:

/seahorse.mid

to the end of my URL, you should be able to retrieve it.

I am having a similar problem with v19.6.  In SF5 mode, an array of
thin vertical slices about 80 pixels tall are removed.  I am not
*currently* having this problem with v19.3, but seem to have a
vague memory (or perhaps a stray dream fragment) of having this
problem early on.  Is it possible that this is a known problem, with
a solution posted somewhere in the mass of Fractint documentation?

Also, thanks to all those who have posted comments on my Netscape
3.x vs 4.x question.  Further input is always welcome.


Later, Bud

Hi.

Netscape won't connect to my server, so I'm checking to see if the basic
method (telneting into the school's user accounts and using Pine) works.

I haven't received anything lately either.

PARs are forthcoming... ;-)

Duplicate messages may be caused by someone setting Netscape (now
FREE!!!)  to "Send messages as both text and HTML format."  This sends
TWO messages every time a message is sent.

The fix... set Netscape to "Send messages as text only."  ;-)

P.S.  Receiving mail now works, but I still can't send mail from Netscape
either in Windows or Linux.  Thus the lack of quoting as I got the
message 1st.

News from the fractint list administrator. Hi!
Sender: [e-mail]
Precedence: bulk
Reply-To: fractint

First, thanks for the efforts to keep on topic. This pays off.
Because the list traffic is so high, this continues to be important.
I am sure everyone has trouble digesting so many messages, so lets
keep our messages focussed on fractal-related content that we are
confident will interest most of the several hundred list subscribers.

Second, I hereby declare that messages about list administration
issues are off topic, except for my messages <grin!> (I intentionally
restrain myself from posting many messages like this one, but by
definition everything I post is on topic :-)) As much as you might
want to answer my messages with essays about how true it is that
people should stay on topic etc. etc., such messages are *also* off
topic! Similarly, when there are list problems such as the
mysterious posting of old list messages, please don't discuss this
on the list - email me if you think it is necessary.

Speaking of which, I don't know the cause of the recent
reposting of old messages. As long as it happens only rarely, I won't
worry, but if we see it again any time soon I will investigate with
xmission.

The xmission majordomo administrators are investigating why one of
our subscribers (the Carlsons) from netcom.com can't post. (Thanks
to the folks who are relaying his their messages to the list so he
can post, albeit indirectly.) His messages bounce with headers that
say his address is "forbidden by the administrator" or some such. If
you ever see such a bounced message (bounced by xmission itself, not
bounced by majordomo) let me know, and DON'T take it personally.
NOBODY is trying to screen you out, least of all me. If I ever have
to ban someone I'll let them know why! I do sometimes have to delete
subscribers who can't receive list messages, which then all bounce to
me. Necessarily I can't explain to such folks what I did - they can't
get mail. If that happens to you (you'll know because you'll stop
getting list messages), just resubscribe.

Recently the findmail folks subscribed their system to our list
(without advance permission), and mirrored it on a web page.
They informed me after the fact. I requested they discontinue it, and
shortly thereafter they stopped (I also unsubscribed their email
address that was mirroring the list to make sure!) The reason I did
this is I don't want to expose your email addresses to the anonymous
public any more than necessary. The request-confirmation subscription
method to the list helps prevent spammers from subscribing, but the
digest is visible on the WWW so people can see your addresses, so
this list isn't really private, though it exposes you a lot less to
spammers than usenet. Even though the findmail web interface was
intriguing and would give the list good exposure, I didn't think I
could in good conscience allow it without making that clear to
you, the list members, in advance. Some of you might not want our
discussions made more public than they are already. As far as I am
concerned that is the end of it. I'll keep an eye out for other
"subscribers" that are really automatic list mirrors.

Finally, in my opinion xmission is a capable list host despite
occasional problems. Everybody should know that xmission is providing
this list for free, and it does cost them effort and resources. I am
not even an xmission user, so they don't owe me anything. W all owe
them thanks!

If you have responses to anything I've written here, PLEASE don't
post it to the list. If you think there are non-fractal issues we
should discuss here, propose it to me privately and I'll entertain
the proposal. But once again, since there's so much list traffic,
let's keep list administration discussion off the list except for
these occasional messages from me to let know know what is happening.

Thanks, and happy fractal discussions!

Tim Wegner

Subject: (fractint) Explanation, parameters, & formulas--range (long)
Date: 23 Jan 1998 19:48:24 -0700 (MST)

comment { ; narrative copyright Kerry Mitchell

Range

In the range coloring schemes, the pixels of the Julia set images
are only colored when the iterate (of a component of it) falls within
a specified range.  This is similar to the bubble method, which only
treats orbits that pass close to the origin.  With an appropriate
choice of parameters, the range schemes can be forced to generate
bubbles-type images.  However, the intent of the range method was
to render Julia sets through thin rings of color, using a relatively
small range of magnitudes in which to trap the orbit.

The simplest case is shown in the range-r formulas.  Here, the orbit
is monitored until the magnitude of the iterate falls within a
specified range.  When this occurs, that iterate is saved.  Upon
bailout (either escape or maximum iterations), the last iterate
falling within the range is recalled, and its polar angle shown via
decomposition coloring.  Depending on the range chosen, the results
can be circular rings, pinched loops (figure "8"), or open loops.
The shapes are definitely non-fractal, but are assembled in such a
way to recover the underlying fractal structure.

Choosing the range is very important, as a greatly impacts the image.
The most direct route is to simply specify the upper and lower bounds
of the range.  This is the method used in range-r, and can require a
great deal of thought, to coordinate a range with the Julia parameter.
The other formulas using this method adust the ranges depending on the
Julia parameter c.  The range parameters are set by the user, the
center and the width.  For example, choosing a center of 1.0 and a
width of 0.1 means that the range will extend from 0.95 to 1.05, half
the width either side of the center.  The value of the center depends
on the the formula chosen.  In range-r-1, the basis for the range is
|c|, so the above choices would result in a range from 95% |c| to
105% |c|.  This basis was chosen since c is the first iterate of 0
(0^2 + c = c), and zero is the critical point of z^2 + c.  Another
way of looking at it is that, by choosing a range centered around c,
the orbit of 0 will fall into the range on the first iteration.  The
formulas range-r-2 and -3 use the second and third iterations,
respectively, so their bases are |sqr(c)+c| and |sqr(sqr(c)+c)+c|.

This method opens itself up to many variations.  For example, instead
of monitoring the magnitude of the iterate, the real or imaginary
components can be tracked.  The formulas range-x and range-y perform
this.  In range-x, the real part of the iterate is watched.  When it
falls into the target range, the imaginary part of the iterate is
scaled and used as the decomposition angle.  Range-y does the same
thing, switching the roles of the real and imaginary parts.  Each is
offered with the 4 above range setting options:  explicit, c, sqr(c)+c,
sqr(sqr(c)+c)+c (the formulas are named similar to the range-r entries,
substituting -x or -y as appropriate).

Each of the above formulas uses the last occurance of an iterate inside
the target range to color the pixel.  If the orbit is such that the
range is hit many times, that prior information is lost.  One manner to
recover part of that information is with the rangecount formulas.  The
basic setup is the same as the range formulas, but now the decomposition
angle is the count of how many times the orbit landed in the range.  A
scale factor is available to convert the count into a useable angle.
This method seems to work especially well when the range width is
increased, to increase the hit count and make more colors available.

Subject: (fractint) Is this a great list or what?!?!?
Date: 24 Jan 1998 16:19:19 -0800

Hi folks,

I have just received some help with my Coloring 101.  Thanks a million!
However I am confused (suspect there is an error in here somewhere).

I'm trying to simulate the simple stuff Fractint does so I can then go
on to more interesting complications and still understand what is happening.

Consider decomp.

Here is a formula:

decomposable-M {
  continue = 1,     ; Set flag for continuation.
  z = 0,
  c = pixel,   ; set up the pixel to color
  iter = 0     ; keep our own count
  :                 ; initialization.
  if (|z| > 4)      ; Bailout at 4
    continue = 0    ; Set flag to force an exit.
    z = z - iter    ; take out the iterations (?1)
  else              ; Fractint put in
    z = sqr(z) + c  ; standard MSet iteration
  endif   ; Does if, else and endif have to be on separate lines????
  iter = iter + 1   ; keep our own count (?2)
  continue == 1     ; Continue while =1.
}

Now this is the result, as I said, of some help. Well it is not exactly as I
received it,
but that version got me only a black screen. This makes colors.

decomposable-M {
  reset=1960 type=formula formulaname=decomposable-M
  periodicity=0
  center-mag=-0.75/0.0/.4/1/0
  float=y maxiter=256 inside=0 decomp=256
  colors=000000<30>zKU<30>211000000<14\
  >000010030<29>0z0<30>020000000<14>00\
  0110330<29>zz0<30>220000000<29>000
}

Now, it does not matter what we put for outside
(iter, real, imag, mult, summ, atan)
since decomp takes over for this.  So in this example do I need
to subtract iter from z just before exit?  I think not.
( I think not, therefor I am not...)
Because I can take out the z=z-iter and get the same picture!

I can take out the two lines containing '(?n)' in the frm.  But let us not
quit yet.  Remember I want to use this as a first step. So the line
marked (?1) will have something like

z = exp(2*pi*i*mycolor/256)

Now do I need to take out iter?  I guess I do, so I have

z = exp(2*pi*i*mycolor/256) - iter

Right?   If I want total control of the color, I can use decomp, but
I don't have to (right). I can use outside = summ or real, put

z = mycolor-iter

Right?  But I seem to recall having to subtract 8 also.

Anyway, thank you all for the help.  I'm preparing a
Coloring 101 Lesson 1. that has some great math results,
especially useful for you research types who like to explore
in close to the MSet components like the big cardioid,
the big circle and even some smaller ones!

Thanks,
Jay

The only reason I can think of for subtracting the iterations
is when outside=summ, real or imag.  This is when you want the
value of z to be a direct index into the colormap.  This is the
method I've used on all the formulas I've sent to this list.

Geez, I almost wish you hadn't pointed that out, but I guess
it's best I know the ugly truth.  I should have been suspicious
of integer artifacts from the nearly-hyperbolic "biomorph" spikes
in ap-102.  Sadly, I find that all of the half-dozen images I
genned from jul1-138 lose their best features when generated
in their "true" form, which means they're not really fractals.

Bummer.

Well, they may be fractals, just not the fractals they claim to be. Sounds
a bit like the so-called "shadowing lemma" which states that, although the
trajectory you see in a Lorenz-type fractal is not really the trajectory
you specified, because of roundoff errors and such, it _is_ a genuine
trajectory in the dynamical system.

Hey, so long as they look good, who cares? I liked them. Think of it as two
for the price of one!

Subject: (fractint) Reuse of previous zooms
Date: 26 Jan 1998 11:34:11 -0000

If you zoom in to a fractal there is potential for part of the old image to
be used to calculate the new one.

For example, if the zoom box is half as wide and half as high as the old
image, then one in four of the pixels in the new image have already been
calculated.  Using some kind of guessing algorithm, most of the others
could be worked out very quickly.

This would make zooming into fractals a great deal faster.

Glad you liked my page. I tried to make it simple, yet elegant. Try to
anyways.

It was a while back when I did that I cannot truly remember how I did it.
But I remember changing the water levels. I believe the colors has something
to do with it also. Try different colors and see what you come up with.
I haven't had any chance to make more 3D images, but I will in the future.
Thanx for reminding me!!...^_^

Subject: (fractint) Next version of DEEPER now avail.

All,
    A more user-friendly, better tested version of the DEEPER program can be
dowloaded at: < http://boralf.agsci.colostate.edu/~jason/personal/deeper.html >.
The zip file includes the executable, source code, readme file, and a modified
CFG file (you can either copy it over FRACTINT.CFG or just modify your existing
CFG file to match the one I provide).  The executable has been through many
more tests, and seems to be portable.

    For those who don't know, DEEPER is a companion program for FRACTINT 19.6
which allows the unattended zooming of the Mandelbrot Set (and probably others,
too).  Using a simple 'fringe recognizing' algorithm, DEEPER performs zoom after
zoom on th M-Set without human guidance.  For more info, read the README file
which can be viewed at the URL above.  Comments, suggestions, etc are
appreciated.

P.s., I don't think that finding a fractal which resembles a Nazi symbol
necessarily means that the finder practices or subscribes to Nazi-oriented acts
or philosophies.  Same goes for users of Microsoft products, I hope...! :)

Ok, here's my ignorance showing . . . again.  Or maybe my absence.  What
are you talking about, Jay?  Whatever it is, I must be one of the "few
folk" . . .

I've been thinking the same thing. Unfortunately, I'm not a programmer, and
will be no help at all, if you don't count sitting in the wings and
chanting, "Go! go! go!"

I certainly like the idea, but I have had no response to my
post, so I think I'll be dropping the idea.

IMO the token par is just an excuse to have people look at
more of your images!! :)

An offline webpage once a month, with all that monts pars??
We could just leave Fractint running overnight.
BTW if we are going to be viewing files on our own computers
there is no need to generate thumbs, as the browser can
scale the images for us.

Subject: (fractint) PNG and Netscape
Date: 26 Jan 1998 19:32:00 -0800

Reverting to the topic of PNG support on the web, I downloaded Netscape's
Communicator 4.04 over the week end. It will open PNG files without the
necessity of finding and installing a plug in.  Also, it is now
free.....and stable. The interface leans more toward IE in this version
.....but not disturbingly so.....and the wysiwyg html editor has many of
the bugs that used to drive me nuts fixed.  And as we all know, Netscape
does animated gifs and java better than IE.

Some stats......download size.....about 11 megs
Download time....about an hour thru my 28.8 modem on a Sunday am (optimum
download period)
Installed size for "typical" installation.....41.5megs (this includes cool
chat and other features which may not be considered essential)
Installation problems .....I did my installation without taking off
Netscape Gold 3.0 (except I moved my bookmarks to safety).....none

Bottom line....assuming hard disk space....Communicator is a good choice
for the upcoming switch to PNG

Only negative......mail seemed to take a long time to download thru the
Communicator client but was well handled once it arrived.

Subject: (fractint) Next version of DEEPER now avail.
Date: 18 Jan 1998 21:18:49 -0500

All,
    A more user-friendly, better tested version of the DEEPER program can be
dowloaded at: < http://boralf.agsci.colostate.edu/~jason/personal/deeper.html >.
The zip file includes the executable, source code, readme file, and a modified
CFG file (you can either copy it over FRACTINT.CFG or just modify your existing
CFG file to match the one I provide).  The executable has been through many
more tests, and seems to be portable.

    For those who don't know, DEEPER is a companion program for FRACTINT 19.6
which allows the unattended zooming of the Mandelbrot Set (and probably others,
too).  Using a simple 'fringe recognizing' algorithm, DEEPER performs zoom after
zoom on th M-Set without human guidance.  For more info, read the README file
which can be viewed at the URL above.  Comments, suggestions, etc are
appreciated.

P.s., I don't think that finding a fractal which resembles a Nazi symbol
necessarily means that the finder practices or subscribes to Nazi-oriented acts
or philosophies.  Same goes for users of Microsoft products, I hope...! :)

Fractint for some reason didn't save the colors correctly in one of the

Yep, this is a duplicate.  Here's my new theory now that the Netscape one
is shattered...

Hi Fractintiers,

You can still follow the adventures of Dr. J, the mad scientist of
fractal space at

http://home.san.rr.com/jayrhill/FotN/FotNindx.html

Last we heard he may have over consumed on some beverage
after the FractoBowl Game.

Hopefully there are some useful formula hints there from
someone who is also learning about this from this list.

Enjoy
Jay

Bud, I liked your formula and played around with it a good bit - that
"super-generalization" you spoke of offers a lot of choices. I posted
the first four pars a few days ago, but the list was down and it did not
seem to get through. Since then I added two more. I hope you'll find
them interesting. Gedeon

Here is Mark Christenson's formula:

gravijul { ; r^(-2) Mark Christenson 1/25/98
; defaults: p1 = (1,0) p2 = (0,0) p3 = (4,0)
   z = pixel:
   w = fn1(z)
   z = fn3(p1/fn2(w*w)) + p2
    |z| < p3
  }

What measure would you like to use?

There is the boundary of the Cardoid with the attached buds.
In this case, it is a fractal whose dimension I measured a few
years ago. I calculated the circumference as a function of
limiting bud size.

These is also the boundary around all of the set. I measured
this using the arc length of the contours.

There may be even other measures.

I don't have the numbers handy.

From a philosophical point of view, images that depend on integer
artifacts can still be fractals. Fractals can be generated from
discontinuous functions with strange rounding and multiple cases as
easily as from iterating simple, elegant, differentiable nonlinear
functions.

To take the point further, one of the points of fractal theory is
to break the prejudice that prefers the well behaved, smooth
functions of elemntary calculus, and sneers at the others as
unimportant counter examples. Perhaps we have just pushed the same
prejudice one level deeper when we acknowlege highly "ill behaved"
fractal functions as long as they are defined by iterating nice,
friendly, smooth, well-defined functions like z^2+c.

That's my view as a philosopher, but not my view as a programmer. A
good programmer takes backwards compatability very seriously, because
the alternative is to create huge problems for users every time a
new software version is released. Integer artifacts give programmers
fits when they happen accidently, because they are hard to control. I
would prefer that artists use floating point and the various rounding
functions, because then the software behaves more robustly when the
internals change. Perhaps we need some new functions proposed that
satisfy those who enjoy exploring artifacts.

Integer math surely is going to be removed from fractint. We're
just not sure how soon.

That's what I want to know. What did you do about the arc length of the
contours to determine the boundary?

Yes, it would... IF you zoom in by half.  If you zoom in by, say, making
the zoom box .084637745656 as wide and .084637745656 as high (random
numbers), there is a very high likelyhood that NONE of the pixels will have
been calculated already.

You would have to limit zooming in to simple rational numbers, like 1/3,
1/4, 1/10... for it to work.

Please don't post messages like this to the fractint list!!! ONLY
post messages to this list that have to do with fractals. The "virus"
message was a fraud, but even if it weren't a fraud, this is not a
virus discussion list!

Sorry to bother everyone with this, but I felt this message needed a
response. Also, folks, if you see off topic messages, you don't need
to personally take care of it by posting a response; as list
administrator, I will. (Feel free to email me personally
if yopu think I missed something.)

Thanks for your patience, and glad to see things are getting back to
normal. back to fractals!

I've been expecting this myself for a while now - Fractint's integer
arithmetic was after all introduced for the sake of speed, and I for one
find that the floating-point algorithms are much _faster_ on my machine,
and have been since my 486. (My 386/IIT was faster at floating point than
integer for that matter).

These days I only ever use integer arithmetic for deliberately introducing
artefacts. The thing is, I really _like_ some of these artefacts (my
Astro.frm formulae are cases in point). So when integer arithmetic is
removed from Fractint (Fractfloat? Ouch...) I would like to see some sort
of fossil support retained.

The Farey series provides a convenient way to identify the disks along the
cardioids in the Mandelbrot set.  For review, the Farey sequence starts:

0/1, 1/1 in the first generation, followed by
0/1, 1/2, 1/1;
0/1, 1/3, 1/2, 2/3, 1/1; etc.

For each subsequent level, every second term is a combination of two terms
from the previous generation.  For example, the 1/3 comes from (0+1)/(1+2)
from the previous step.

For the Mandelbrot set, let 0/1 represent the cusp (0.25,0), 1/2 is the
large disk at -1, and 1/1 is back to the cusp.  Looking at the third level
above, between 0/1 and 1/2 is 1/3.  This corresponds to the large disk at
the top of the cardioid (and 2/3 is the other disk at the bottom).
Between any two disks with adjacent Farey entries at generation j, the
largest disk between those two has the Farey number between those two at
generation j+1.  In other words, the largest disk between disks 1/3 and
1/2 is disk (1+1)/(2+3) = 2/5.

Aside from labelling, the Farey numbers also serve as a coordinate.  Let

theta = 2 * pi * m/n, where

m/n is the Farey fraction for the given disk.  Then,

r = 0.5 * (1 - cos(theta)),
x = r * cos(theta) + 0.25,
y = r * sin(theta),
c = x + i*y

c is the point of tangency between the main cardioid and the m/n disk.
Since all fractions eventually show up in the Farey series, all fractions
have corresponding disks.  Also, if we replace the rational number m/n
with an irrational number (such as phi = 0.618034...), then the
corresponding c will be a cardioid boundary point with no tangent disk.
Therefore, it will have a chaotic orbit.  (An easier way to get chaotic
points is to use a rational number for theta.  Since pi is irrational,
that guarantees that the factor (m/n in the Farey case) will also be
irrational.)

The point abouve above chaotic orbits brings up another Farey connection.
Each disk has a corresponding Farey number m/n, which is in lowest terms.
The denominator, n, indicates the periodicity of the disk tangent to the
cardioid at the point c.  For example, with m/n = 1/2, the tangency point
is at the disk of periodicity 2 at -1.  The 1/3 and 2/3 disks are tangent
to the period 3 disks at the top and bottom.

These are the connections between the Farey sequence and the Mandelbrot
set of which I'm aware.  Any others?

r = 0.5 * (1 - cos(theta)),
x = r * cos(theta) + 0.25,
y = r * sin(theta),
c = x + i*y

c is the point of tangency between the main cardioid and the m/n disk.
Since all fractions eventually show up in the Farey series, all fractions
have corresponding disks.  Also, if we replace the rational number m/n
with an irrational number (such as phi = 0.618034...), then the
corresponding c will be a cardioid boundary point with no tangent disk.
Therefore, it will have a chaotic orbit.  (An easier way to get chaotic
points is to use a rational number for theta.  Since pi is irrational,
that guarantees that the factor (m/n in the Farey case) will also be
irrational.)

The point abouve above chaotic orbits brings up another Farey connection.
Each disk has a corresponding Farey number m/n, which is in lowest terms.
The denominator, n, indicates the periodicity of the disk tangent to the
cardioid at the point c.  For example, with m/n = 1/2, the tangency point
is at the disk of periodicity 2 at -1.  The 1/3 and 2/3 disks are tangent
to the period 3 disks at the top and bottom.

These are the connections between the Farey sequence and the Mandelbrot
set of which I'm aware.  Any others?

F.O.T.N. (Fractal of the Night) 29 Jan 1998 (Garden Path)

Finally, contact with Dr. J.  He just cannot resist those technical
questions.  Alas, he won't answer my email questions about the
FractoBowl games. Since he won't say anything, we can assume
his favorite team lost. Tonight, it would seem, he has been reading his
email and saw something of interest. So I'm taking a break from
the sequence of panoramas, like last nights panorama.

Peter Jakubowicz asked about the perimeter of the Mandelbort
set lakes. I replied, in the usual way, "Been there, done that". Just
kidding, got to stall somehow. But Dr. J put me to shame as only
someone from that fractal space can. He just went for his evening
stroll around the grounds and counted his steps. After all, isn't that
the definition of a fractal perimeter. He says he can take big steps
following the lower count escape contours, which should be obvious.
But as he huffed and puffed around the higher iteration count
contours (see Big Fatso to see why he huffs and puffs)

http://home.san.rr.com/jayrhill/FotN/FotN20.html

he reported he had to take steps about half as long for each contour.
That  is so he can follow the curves. He sent along the following
picture, Figure 1, showing his garden pathways.

http://home.san.rr.com/jayrhill/FotN/FotN29.html
http://home.san.rr.com/jayrhill/FotN/FotNindx.html

Figure 1. Dr. J's paths around the ground of his home.

  n     perimeter

14  22.1410545197811443
15  25.6606374585242084

The perimeter seems to  be a function of n, the iteration count for
the contour, namely, a one fifth power.

P = C1*2^(n/5)

Since Dr. J had to take steps half as long to insure getting around
every wrinkle in the path, we know his step lengths are

L=C2*2^(-n)

Therefore, the dimension must be the exponent in P/L.

P/L = C*2^(6/5)

and the dimension is 6/5.

Enjoy
Jay
PS. Newton's method was used to follow the contour around the
MSet. Approximate halving the step size was required to prevent
straying from the path. Following the path to higher order is of
ever more difficulty.  I have reached the limits of 80 bit floats and
weekend runs on a P200.  If the trend is real, the dimension
using this measure is 6/5.

Unfortunately, at 1024x768 some glaring solid-guess errors occur, and you

Infinite. (In fact it has dimension 2, which you can feel is true if you
look at a deephorse or zoom about four full zooms around the point where
the usual golden ratio Siegel disk Julia is found.)
A better question: Does the boundary of the M-set have a nonvanishing
area? (Astonishingly, some plane fractal curves of dimension 2 have a
positive area, even not including dragon and Peano curves.)

Suggested usage of tesseral @ 1024 x 768 for this one in this par. Also
color cycled just a bit as can be seen by comparison:

For Jay: I saw that area (or very similar - right side) but thought I would
go with what I had. Cycling the colors in the area you posted gives a bit
more than I thought it would. Maybe I'll swap color maps on that one and
see what I get...something like this (trouble is with the banding...):

There is also another thing that could be done, no matter what zoom
factor one uses:

The automatic logartithmic pallette is calculated by calculating every
pixel at the border of the image. This mechanism could reuse the
previous zoom to establish the new log pallette instead of calculating
it all again. One would save several minutes without loosing quality.

The only problem would be that only the colour value is stored and not
the itterations, the log value would therefore be the lowest iteration
that would get that colour, which could be off a few iterations, but
who cares if it saves several minutes (~42 minutes on my last
deepzoom).

One wouldn have to limit it to those aspect ratios. There could be a
flag (or modifier) that rezises the zoombox to an integer scaling and
when zooming the programm could scan all horizontal lines whether they
would fall onto one line in the original picture (within 10^-3 of a
pixel or similar value). Then it could scan all vertical lines with
the same method and copy all intersections from the original image to
the new one. Something like Boundaryguessing would immediatly accept
those points and other methods could be changed to accept them.

The time taken to copy any relevant points is irrelevant and the time
saved can be huge.

May the Source be with you.

Its not strictly true, but for everyone who uses an Operating system
its true. DAUs with some "Game Playing Sytems", with a name similar to
those things in the wall, that contains glas and that you can look
through, might be using a "Wordprocessor" from the same firm to read
their emails. If an email then contains a harmfull "Macro" (as the
very same Firm calls it) it is executed (thats enabled by default) and
it can be harmfull.

Well, its offtopic and hopefully nobody here does it, but its still
intresting to know that nowadays this virus fraud email could really
be true (for DAUs).

Given p3's use as the bailout, you can enforce your default option by
adding the following to the initialization section of the formula:

  IF (p3 <= 0)
    p3 = (4, 0)
  ENDIF

Good point, but who says I *want* to enforce the default?  In fact,
I usually (strike that -- more like "often") override it (take a closer
look at the original post).  Here's yet another example; as the name
implies, it's closely related to gj09.

Try setting the bailout to 4 for gj09.  It's interesting, but 2.95
produced an image with a nice "chiseled" texture (although
I must admit I love them both, as I do all my fractal brain farts).

B-b-bud.

Date: 29 Jan 1998 10:32:41 -0600

First off, I'd like to say "THANKS" to the person who posted the bogus
virus message.  I didn't find out it was a hoax until I checked my
messages this morning.  Of course, I had already passed on the message
to a few family members, and now I have to issue retractions and
apologies.  I hereby sentence you to owing us a par a week for the rest
of your life, and I hope the other fractalers out there support me! <hg>

Now, on with the real business...

I have decided to start a 4-Dimensional Hall of Shame.  Simply put,
these are quat julias or hypercomplex julias rendered with type julibrot
that don't live up to what would be expected from looking at the area of
the quat or hypercomplex that they come from.

Note that these WILL take a long time to generate if you aren't using
XFractint, especially for the recommended resolution of 1024x768.  So,
for the impatient of you, I *may* put up a website on my school
account.  However, the space is small, and I have to figure out how to
do it, so don't hold your breath.  ;-)

Anyway, here's the first two inductees:

--shame.par--

quat1              { ; our first inductee into the 4-dimensional hall of
shame
  reset=1960 type=julibrot julibrotfromto=-1/1/0/0

  }

--END of shame.par--

I'll try to do this every two weeks or so, at least while I'm at school.

Sorry, George.  *I* just took a closer look at *your* post and see
what you mean.  It's a nice option, but I'm still using v19.3 (which
does not support conditional processing) until I get a response from
the wizards re my "image shift" (1/20/98) and "color-map loading"
(1/23/98) bug posts, except when I require conditional processing.
(The latter post was a response to Paul Carlson's post on 1/19).

Thanks anyway, Bud

This is a variation on the well known "Good Times" hoax.  The virus is
the warning itself, you just propagated the virus by "warning" us.

See <URL: http://www.sarc.com/> under "virus hoaxes"

In the future, before you pass on a virus "warning" from someone else,
check a site like that one (sarc is Symantec AntiVirus Research Center,
run by Symantec, which makes Norton Anti-Virus).  The virus companies
are aware of all the hoaxes long before most people have heard of
them.  Whenever passing on a "security alert", it is crucial that you
check the truthfulness of the report.  Many times more harm than good
is done by passing false reports and causing people to worry about and
spend time investigating non-existent problems.

I agree, the usual answer to the question - what is the dimension of the
MSet...
is 2.

How ever the question here is a little different. It is perhaps not well
stated mathematically.  The dimension of the coast of the
'contiguous' Mandelbrot set (the cardioid and attached buds, skipping the
filaments and midgets) is not dimension 2.

The algorithm used by Dr. J shows an early estimate of 6/5. However if
the calculation were to have been stopped at half as much, a different
value would have obtained.  If the particular method Dr. J used were
continued, either the assumption of doubling the steps with each
contour is not needed or the estimate will slowly increase toward 2.

I'm going to modify the FotN page lest anyone get led astray  :-)

Yes, use type=ifs and store the IFS mappings in an IFS file.  Flame
generates the IFS mappings automatically.  You should be able to
convert one of its stored mappings to a fractint IFS file.

A better choice than Symantec (which has been involved in
fostering virus scares in the past) is the Computer Virus
Myths Page at

http://kumite.com/myths/

or the CIAC site at

http://ciac.llnl.gov/ciac/

Now the question becomes, given the amount of time some
of us spend using Fractint, instead of something more
productive, maybe we should classify Fractint as a virus?

F.O.T.N. (Fractal of the Night) 30 Jan 1998 (Fractint Virus)


I just found out why Dr. J has been mostly unavailable for comment
since the FractoBowl. He has come down with some kind of fractal
flu.  Dr. J., it would seem has caught a bad case of something, which
especially in fractal space, can result in quarantine.  Positive ID of
the cause was just announced. He has the dreaded and feared Fractint
Virus. This virus can result in previously well connected fractals
becoming Fatou dust in hours. See Figure 1.

http://home.san.rr.com/jayrhill/FotN/FotN30.html
Figure 1. Dr. J has the dreaded and feared Fractint Virus.

Please, if you know of a cure for this illness, let us know immediately.
Dr. J does not have much time.

Stay healthy,
Jay

But what do you mean by "contiguous", then? The M-set is simply connected,
which would make the entire boundary (midgets and filaments both) a simple
closed curve. There are other characterisations of "connectedness" for
which the connectedness of the M-set is not known (exercises for the
reader), but I'm not sure if they apply in this case. If they do, I would
be happy to be enlightened.

Anyway, how much of those filaments are no more than really really really
tiny M-sets? Whatever that means mathematically.

please, can anyone tell me where I can find the Hermann Ring formula?
May be I lost some posting.

Umm....

Exactly how do I place these FRM & PAR files into FRACTINT to use
them?  I'm not new to FRACTINT but I am new to the idea of grabbing
stuff off the list and slapping it into my copy of FRACTINT.  Also if
the par calls for a color scheme I don't have how do I tell it to use
another one.

Subject: (fractint) How long _is_ the coast of the M-set???
Date: 30 Jan 1998 07:47:27 -0800


OK.  How can the M-set be infinitely fuzzy, have an infinite perimeter,
_and_ be simply connected at the same time? If you can measure its area,
then why is the perimeter infinite. I was thinking there must be some way
of closing in on the perimeter; that it must approach a limit, the way the
area does.

I know the standard answer, that its dimension is 2, ergo it's perimeter is
infinite. But is it not something like the behavior of matter? At the
subatomic level things are really weird, unmeasurable, but not so at the
quotidian level; for example, I'm 5'11'', and I exist whether someone is
holding a yardstick to me or not. Similarly, when you look at the M-set
close up, zoom in on it, it gets weird; but from a distance it looks like
an island, connected. Maybe I just don't know enough math??? This M-set
connectedness problem has been nagging at me for a while.

Well, I guess that's enough obfuscating,

Peter

Date: 30 Jan 1998 09:05:48 -0500

James,

You wrote asking how to get from a message to an image, and how to change
colors.

1. Add the image entry to a DOS text file with the extension .par and the
formula to one with an extension .frm, and make sure those files are in the
directories where your other .par and .frm files are located, respectively.
This takes a bit of work, but in the long run is best. A short cut is to
add the letters "frm:" in front of the formula (sometimes this is already
done in the message). Then you can simply add the whole message to a .par
file, but be cautioned that the formula will only be available for drawing
the image. You won't be able to access it otherwise. If you add the formula
to a .frm file, don't forget to delete the "frm:" identifier.

   I gather from your message that you know how to navigate Fractint to
draw the image at this point.

2. If a .par entry calls for a .map file you don't have, fractint will
automatically use the default .map file (appropriately named default.map).
To change the color palette, hit "C" and then "L". This will bring up a
list of the .map files in your default .map directory. Selecting one will
apply that .map file to you image.

   You can cycle colors of the current palette by hitting "+" or "-".

   You can edit the current palette by hitting "e" and then "<CR>". See the
Fractint documentation for how to manipulate the palette.

   <ESC> gets you out of the color mode and back to the regular image.

   You can save the current palette as a .map file by hitting "C" and then
"S".

This may come as a shock, but the Koch snowflake is the same way.  Its
perimeter is infinite because each stap in its construction multiplies
the perimeter by 4/3, yet it has less area than a circle circumscribed
about it!  And its fractal dimension is only 1.26 or something low like
that.

About it and the M-set being "infinitely fuzzy,"  that's probably a
different matter.  If you mean the little arms and spirals that contain
the minibrots, then, no, I admit the Koch snowflake doesn't have those.
But you don't even need the dimension of the boundary to reach 2 to get
an infinite perimeter.

Hmmm, I'm pretty sure someone proved it, but I don't remeber how.  What
I do remember is that in the excellent book "The Beauty of Fractals"
there was a description of one way to prove it.  The way described was
to make a model by pinching points on a unit circle together, prove that
the model was connected, then prove that the model was equivalent th the
M-set, and voila!  I don't know if it was actually done like that,
though.

There is a simple way to show that a curve may have an infinite length but
encloses a finite area.
Start with an equilateral triangle and its circumcircle. Then transform
the triangle to have a Koch snowflake : the Koch curve has an infinite
length but it is surrounded by the circle. Therefore, the area enclosed is
limited.

Or look at an island : do you accept, as stated by Mandelbrot that the
length of its coat is infinite ? But the area of the island is limited.

Very cool!  I especially liked "where...".  I haven't played with

such a small tweak could fragment the fractal in that manner!

Simple closed curve?? I think not... it has infinitely many points of
self-contact. (Filament necked down points, filament branch points, cusps
and component roots...) The boundary of a connected *open* set is a simple
closed curve. The M-set is a connected *closed* set.

>Anyway, how much of those filaments are no more than really really really
>tiny M-sets? Whatever that means mathematically.

The filaments include mini Mandelbrots but also various points of
accumulation of the M-set that are not in any mini Mandelbrot (either
inside or on the boundary of one of its disks or cardioids that is).
The preperiodic Misiurewicz points are some (but not all) of these points of
accumulation (for example the "band merging" point where the sequence of
front buds ends and the spike begins, is not a Misiurewicz point).

This has been discussed at length here. The problem is in the servers
and emailers. Most of us get the postings just fine. You can edit these
'special' space characters out using PFE

http://www.lancs.ac.uk/people/cpaap/pfe

We can give you some special help on these files (the =3D problem
and the aaaaa problem) if you specify exactly which post gave you
trouble. I can email you a good copy or put one on my web site.
Unfortunately, the official archive suffers from these problems so
there is no relief there.

An example of the help available is
http://home.san.rr.com/jayrhill/CARLSON.PAR
which I placed there and maintain because Paul Carlson was not
able to post except indirectly. All of his fine formula were messed
up in the archive.  Several subscribers were having great difficulty.

An infinite perimeter can easily enclose a finite area. Take a triangle.
(Equilateral). Perimeter is 3, area is 1 (using custom units here). Add a
one-third scale triangle at the center of each side: area is now 1/3 greater
than what it was, and boundary is 4/3 what it was. Repeat adding ever smaller
triangles to the center of each side, and the perimeter keeps going by 4/3
while the area keeps adding a smaller and smaller amount. The perimeter
tends to infinity, the area to a finite amount.

contiguous - adj
1. in physical contact; touching along all or most of one side.
2. near, next, or adjacent

In this case, since the first derivative of the separation distance between
a bud and its parent is zero while at the Feigenbaum points it is very
different, I would call contiguous the attached buds and parent cardioid.
One can change c smoothly along the real line for example and get a
progression of periodic orbits. When you get to the Feigenbuam point at

I apologise for the encoding on the second posting of hring.par. I can
only surmise that some clueless moron in the admin here at freenet has
decided to change the settings on the mail software we use to encode
outgoing mail. I have informed them that their change is far from
transparent and is actually causing at least 2 freenet users problems,
hopefully, they will do away with this ill-conceived and
poorly-thought-out change very soon. I'll keep you posted...
 Until then, since us lowly users on freenet don't have access to change
the mail settings, such as encoding, I'm afraid I either won't be able to
post PARs, if you won't accept encoded ones, or else I will have to post
encoded PARs and you will have to decode them. In that case I would love
it if someone could please take any encoded pars I post, fix them in PFE
and repost them for others' benefit. If there are any volunteers
(obviously, you need to not be on freenet), then thanks... if not, then I
guess I'll just wait until freenet fixes this. If they ever do. If they
don't, I might unsubscribe this list here and subscribe from my Hotmail

These a' things seem to be produced by notepad sometimes...
Apparently it has to do with the fact that notepad saves
spaces as a different ascii number than Dos programs.

I usually get around this problem by saving the par with
notepad, and then loading it into DOS edit and doing a
search and replace replacing the a' thingys with spaces

Subject: (fractint) (Fractint) Formula Fricassee
Date: 30 Jan 1998 15:42:21 -0500

Can someone help me out with my formula? This:

TEST4 {
  z= Pixel, z=Sqr(z)
x=real(z), y=imag(z), tst=p1+4, t=1+pixel
IF (whitesq)
   y=Pixel-x/z
   x=Pixel-y/z
   x=abs(x)+fn1(y)
   y=abs(y)+fn1(x)
   Pixel=fn2(x*y)
   Pixel=fn1(Pixel)
ELSE
   y=Pixel-x/z
   x=Pixel-y/z
   x=abs(x)+fn1(y)
   y=abs(y)+fn1(x)
   Pixel=fn2(x*y)
ENDIF
:
}

just produces a blue screen. And, yes, I realize that I have some unused
vars. Same with this variant:

TEST4 {
  z= Pixel, z=Sqr(z)
x=real(z), y=imag(z), tst=p1+4, t=1+pixel
   y=Pixel-x/z
   x=Pixel-y/z
   x=abs(x)+fn1(y)
   y=abs(y)+fn1(x)
   Pixel=fn2(x*y)
IF (whitesq)
   Pixel=fn1(Pixel)
ELSE
ENDIF
:
}


However, this:

TEST3 {
  z= Pixel, z=Sqr(z)
  tst=p1+4, t=1+pixel, x=real(z), y=imag(z)
y=Pixel-x/z
x=Pixel-y/z
x=abs(x)+fn1(y)
y=abs(y)+fn1(x)
Pixel=fn2(x*y)
Pixel=fn1(Pixel)
}

and this:

TEST2

  z= Pixel, z=Sqr(z)
  tst=p1+4, t=1+pixel, x=real(z), y=imag(z)
y=Pixel-x/z
x=Pixel-y/z
x=abs(x)+fn1(y)
y=abs(y)+fn1(x)
Pixel=fn2(x*y)

}

function perfectly. Whaddid I do wrong?

contiguous - adj
1. in physical contact; touching along all or most of one side.
2. near, next, or adjacent

Since the cardioids and buds are often referred to as the lake, I
took the original question about the coast to be the lakes'
boundaries - an interesting question as I shall show.

In this case, since the first derivative of the separation distance
between a bud and its parent is zero while at the Feigenbaum
points it is very different, I would call "contiguous" the attached buds
and parent cardioid.  The derivative I'm refering to is with respect
to the tangent direction.  One can change c, in the Mandelbrot
iteration formula, smoothly along the real line, for example, and
get a progression of periodic orbits. When you get to the
Feigenbaum point at

-1.401155189092050600523826787893861292226308...

we see a change in the pattern.  The orbit is chaotic. We have
entered the 'chaos zone' - dee-dee dee-dee dee-dee.
Oopps sorry Rod Sterling.   See Jim Muth's Fractal-Art list
F.O.T.D., 27-01 (String of Bays) post or use the par below.
http://home.att.net/~Paul.N.Lee/FotD/FotD.html
In the center, we see a tower showing the row of ever small buds
approaching the Feigenbaum point. Their size approaches a
geometric progression with the Feigenbaum constant
4.6692016091029906718532038204662... as the size ratio. They
look the same size because of the logarithmic transformation. Now
look at the other two 'towers', each representing the same thing,
namely the spike beyond the Feigenbaum point.  We see a row
of midgets which all look the same size.  They are not really,
since there is a logarithmic transformation involved. But it does
show that near the Feigenbaum point the fraction of the real
line inside midgets approaches a constant. And, I claim, that
constant is not unity. There is a zon-zero portion which is chaotic
or pre-periodic.  Several years ago, I calculated this fraction. I'm
trying to locate my post to sci.fractals. The fraction of the real line
from -2 to .25 that was periodic was about 82%, as I recall.

It therefore, is of interest to some, to separate the midgets from the
rest.  For example, I have calculated a lower bound of the area of
the interior of the MSet, that being the part contained within the
"contiguous" midgets.  See this URL and references there.

http://www.geocities.com/CapeCanaveral/Lab/3825/Period-Area-16.html

Since there is a non-zero portion of the real line not contained in
any midgets, there may well be a non-zero portion of the MSet
area remaining uncounted in the 'interior' calculations.  This is,
as I understand it, still an open question.

As for the perimeter or dimension of the "contiguous" part of the
Mandelbrot set, I have estimated that also. It comes as a by
product of the area calculation. For each bud, calculate the radius
and sort these. Now make a running perimeter sum vs. radius.
The result gives a measure of the perimeter dimension.  I get
a value close to 1.250 +- 0.003.

 period   'radius'   perimeter
 1      0.61237244  4.00000000

Here's gravijul, from the source.

gravijul { ; generalized r^(-2) by Mark "Bud" Christenson 1/25/98
; defaults: p1 = (1,0) p2 = (0,0) p3 = (4,0)
   z = pixel:

   w = fn1(z)
   z = fn3(p1/fn2(w*w)) + p2
    |z| < p3
  }


Enjoy, Bud

Looks to me like none of them should work; you don't do anything in
the iteration part!  Also, you are assigning to "pixel", which I don't
think is going to do anything meaningful.

This formula has no iteration part, only an initialization part.
Since nothing will be iterated, you will get a constant-color screen
with outside = iter

These formulas have no iteration part either, but they also don't have
the : which separates the initialization from the iteration.  Whatever
you're getting from fractint is either undefined behavior or a bug,
depending on your viewpoint.

Here are Gravijul and the Herman Ring formula.
They were both posted within the last couple of
weeks. Paul Derbyshire wrote a piece of historical interest
about finding the Herman ring.  There is an archive if you want
to read the rest of it.

    |z| < p3

I believe you forwarded Paul's message without editing it....in which case

This can be avoided by copying his formula and pasting it into a new email

Subject: (fractint) ADDGIFS Program
Date: 30 Jan 1998 19:29:55 -0600 (CST)

I just uploaded a program I wrote to the alt.binaries.pictures.fractals
newsgroup.  The program is nice for overlaying fractals, the result
looking much like some of the PHC fractals created with Fractint.  If
anyone does not have access to the newsgroup and would like to try the
program, I'd be glad to email a uuencoded copy to them.  What follows
is the introductory message that I posted to the newsgroup:

Part (1/1) of this message contains ADDGIS.ZIP in uuencoded
format.  This will pkunzip into the files ADDGIFS.EXE and
README.1ST.

ADDGIFS is a combination of three of my prior programs,
GIFS2PNG, GIFS2JPG and GIFS2BMP into one program with
a nice, very easy to use interactive interface.  The
program combines two 256-color GIF files of the same
resolution and outputs a 24-bit PNG, JPEG or BMP file.
The GIF files remain unchanged.

The program is FREEWARE.

Enjoy!

Very nice images! My favorite is "Please!" too. Your comment about it

Bud,
Thanks for your kind words. I worked some more with gravijul. Here are
four more pars.
Judging from the name you gave to your latest post, you must have quite
a few pars!!!
Would you please post some more? Thanks,

Subject: (fractint) january wizzle pars
Date: 30 Jan 1998 20:21:03 -0800

IMHO january was a fantastic month when it came to fractals, pars and
formulas.  I'm offering this far too long list of pars....made with
everyone's formulas....which I just loved.  I had a wonderful time with all
of the formulas posted during the month....

I've taken the liberty of changing the formula file name to *.frm  I picked
that trick up from bud and it seems to work well for me...and I'm sure we
all named our files with some clever..but different name.

I tried to select a variety of images and those which used my newer color
maps. If you have trouble with a formula please email me direct and i'll
try to find it for you.

I was just mucking around... I should probably get off my lazy butt and read
the formulas tutorial. They _did_ work at one point, but then Fractint
crashed and now they don't. I think I'll call it a bug. :)

The above remarks about an encoded hring.par refer to the SECOND posting

first posting, as someone astutely pointed out, is not encoded at all.

Just to clarify things abit...

Ah, but that's only because you don't know my system!  Like Kathy,
I too am a lazy typist.  I use two alpha characters for the fractal type,
and two alphanumeric chars to enumerate primary images; anything
past the first four characters indicates zooms or variants of the primaries.
For example, the post you referred to was

gj081

which breaks down as
gj = gravijul
08 = primary #8
1 = a zoom, most of one quadrant.

By using alphanumerics for "numbers" (10 numbers + 26 lower case
characters), I get modulo-36 symbols and can encode 36^2 = 1296
items with two characters, versus a rather feeble 100 (using numbers
only).  My highest primary is gj0j (or #19), which is actually misleading
since some of these are related (I'm not too rigorous about enforcing
the system), and others are "branch point" images I've saved for
future investigation.

Since I'm talking about branch points and leverage, this is a good point
to give credit where it's due.  The incredible variety these "roll your own"
formulae exhibit is due to the programmers of and contributors to Fractint.
By writing one simple formula with three embedded functions, the 26
functions available (including ident) create 26^3 = 17576 variations!
Add the six (three complex) variables and multiple coloring schemes,
and we're clearly talking orders of infinity... boggles the mind, no?

Anyway, like I said, most of my pars are a bit rough; but since you
insist, here's one that's *almost* ready for prime time (there are a lot
of nice alternatives among the "outside color" options):

gj0e               { ; "Vine" by Mark "Bud" Christenson 1/25/98

  colors=0O0<38>0y00z00z01z0<64>jz0jz0kz0kz0mMfmz0<142>zzz
  cyclerange=0/255
  }

Note: there are some minor errors using the "b" option, but it's
entertaining to see drawn and renders twice as fast as any other
method.  I can't guarantee it will work well at less than 640x480.


BTW Les, I really like "Katy Lied" (no lie)!


Aloha, Bud

Oops, bad idea; the damage is worse than I thought.  Better go with
passes=t (par below is corrected).

Subject: (fractint) A Herman Ring Par
Date: 31 Jan 1998 00:21:45 -0600 (CST)

Here's a Herman Ring par that produces a familiar image but
with a nice difference - a very delicate bright image over
a very bold dark "background."  This is a pretty deep zoom
into the ParabolicFixed image that someone posted the par
for, but with a different colormap.  Don't use solid guessing
on this - too much is lost.  Tesseral works well and cuts
down on the time needed to plot the little Mandy (what my
wife calls a baby 'brot) in the center.

There is a simple way to show that a curve may have an infinite length but
encloses a finite area. Start with an equilateral triangle and its
circumcircle. Then transform the triangle to have a Koch snowflake : the
Koch curve has an infinite length but it is surrounded by the circle.
Therefore, the area enclosed is limited.

Or look at an island : do you accept, as stated by Mandelbrot that the
length of its coat is infinite ? But the area of the island is limited.

I got it.

I had experiences like that too, but they'd all gotten out. It seems the
list occasionally fails to send you your own copy of something, but it
still gets out. (Either that, or it sometimes misses several people, and
sometimes that includes the sender, but I certainly hope not, such an
erratic Mandelbug(qv) would be a pain in the behind to track down!)


Mandelbug: Bug that occurs under deterministic conditions, but with so
many unpredictable factors influencing it, that when it appears might as
well be random. Generally reeealy hard to debug. Name derived from the
chaotic behavior of the Mandelbrot Set with its deterministic
underlying rules. For more details check out the jargon file.

Sorry for what is probably an easy question, but I'm a newbie, both here and to
the world of fractals.
What are these 'fractal dimensions' that everybody keeps talking about? eg.
people keep saying that the M-set is 2-dimensional, and I just saw somebody
saying that the Koch snowflake has Fractal Dimension 1.26 or something like that.
What is a fractal dimension? Also, is there a FAQ that answers questions like
these? Or is there any FAQ at all?

Thanks.

I tried it, I couldn't get it to work at all.

once again, how do I grab these postings and use them too.  Your's
came up as an empty file when I did a cut/paste of the PAR section and
saved as a PAR file.

All others I've tried this with do to same thing.

There is always the sci.fractals FAQ to which many of us have contributed. It
is very good.

http://www.mta.ca/~mctaylor/sci.fractals-faq/

and for your question
http://www.mta.ca/~mctaylor/sci.fractals-faq/dimension.html

I will put together a iFAQ, inFrequently Asked Questions collecting some of the

great essays found on this list.

I had had a lot of problems with some of them and I
have saved all of the posts about this in a couple of files.
There have been several sorts of problems, but I think the
Herman ring frm was straightforward.  The best place to get
the Carlson and Skinner pars is from Jay Hill's site that he
listed yesterday or so.  If you want the set of files email
me and I will send it after work tonight.

Not surprising with the mass of formulas we got in January!!

Here they are

ghost-vert_jul { ; Kerry Mitchell

        ; with a background of vertical lines

        ; real(p2) = bailout
        ; imag(p2) = "ghost" adjustment: set to 0 for only
        ;   background rays, try 2

As an article of faith, OK. But it is not something I would have intuited.
Looking at a triangle and transforming it into the Koch curve, or looking
at the Peano curve, it is pretty easy to understand the idea of finite
area/infinite perimeter. But I don't know of a similar way of transforming
a circle into the Mandelbrot set.

Conversely, I do not see how it can be simply connected, although I am well
aware it has been proved. Perhaps Dr. J might be convinced to dilate a bit
upon this some time ? :)

BTW, Feigenbaum_Panorama = kewl (very well worth waiting 15 min for to see
at high rez) although it raises another question: just how _deep_ is the
Mandelbrot set, anyway.

I don't remember doing that, but I do get confused sometimes at which Paul

You may have heard of external angles, they have been mentioned on this list.
Examples are 2*pi/3 and 2*pi*2/3, these 'map' to the base of the period 2
circle.  Imagine a very large circle. Now grab it at these two angle points
and pinch it down to the point c=-.75. Now you have two bulges, one to the
left, one to the right.  Now grab in the 2*pi*3/3 or equivalently the 0 angle
point. Push it into the period 1 base, c=+.25.  All periodic sequences here
will end with the period 1 base. Now there are three bulges.

Next, grab these points (ignoring the 2*pi), 1/7, 2/7, 3/7, 4/7, 5/7, 6/7.
These go to the bases of the period 3 components: -.125+-.65i, -1.75.  Now
there are about 9 bulges and depending on how inflated it is, is may be
starting to look like the MSet. The big cardioid is forming. The period 2
circle still bulges out to -1.75.  Keep doing this for higher period angles,
(next is p=4, angles are 1/15, 2/15, etc.) and when we get to infinity, finally

all the bulges are nailed down and we have the Mandelbrot set.

All Dr. J has to say is - well let me quote:
"You humans have it easy getting dressed, just one belt, tie your shoes...
When I get dressed, I have an infinite number of belts, and - and, er things

 It goes all the way down...

Subject: (fractint) Truncated Stalks Formula
Date: 31 Jan 1998 17:21:11 -0600 (CST)

The formula below is a variation on my 3D Stalks rendering
method.  The problem with that method (as well as Pickover's
original epsilon cross method) is that the orbit trap is
unbounded (goes to + and - infinity along both axes) producing
stalks which taper out to just a series of unconnected pixels.
The formula below is my "truncated stalks" rendering method or,
if you prefer, my "cross in a circle" method.

The first par is for a Julia set zoom in which the stalks are converging
to a point.  By truncating the stalks before they reach that point
you can see down into the spiral many levels.  A nice effect, I think.
The second par is for an Mset zoom consisting of many crosses (which is
just what you'd expect with a "cross in a circle" orbit trap).

In both pars, you can try making imag(p2) much larger (this increases
the length of the stalks) to see the effect.

Subject: (fractint) More Mandelbrot Fareys
Date: 31 Jan 1998 17:53:28 -0700 (MST)

A few days ago, I posted an article in response to a question about the
connections between the Farey sequence and the Mandelbrot set.  Since
then, I've found a few other connections, which I'll discuss here.

Recall that the Farey sequence is a way to order the fractions m/n, where
m and n are postive integers and have no common factors (like 1/2, 17/101,
etc.).  Each disk around the main cardioid of the Mandelbrot set is
tangent to the cardioid at the point corresponding to m/n turns, where 1
turn = 2 pi radians = 1 full circle.  Specifically, for the m/n disk, the
tangent point c is located at:

theta = m/n * 2 * pi radians,
r = (1 - cos(theta))/2,
x = r * cos(theta) + 0.25,
y = r * sin(theta),
c = x + i*y.

Also, the m/n disk has periodicity of n.

The sizes of the disks are also (approximately) determined by the Farey
number:  the radius of the disk (only the disk at -1 is a true circle, so
"radius" is used approximately) is

radius ~ sin (m/n * pi) / n^2.

For the period 2 circular disk at -1, m/n = 1/2, so the radius formula
gives sin(pi/2)/4 = 1/4.  Since this disk is a circle, the formula agrees
with the geometry exactly (the disk stretches from -0.75 to -1.25 on the
x-axis, so its diameter is 0.5 and its radius is 0.25).  (For the other
disks, the "center" is defined to be that point in the disk whose orbit
contains 0, and the "radius" is the distance from this "center" to the
tangent point.)  This simple formula also describes what happens near the
cusp.  As n (the period of the disk) increases, the disks get smaller.  In
the m=1 case (1/2, 1/3, 1/4, etc.), the size of the disk decreases with
n^3, which is why they seem to disappear into the cusp at 0.25.  Near
"large" disks, the surrounding disks also get smaller.  For example, look
near the 1/3 disk at the top of the cardioid.  On either side of it, from
2/5 on the left and 1/4 on the right, the disks get smaller as they lead
up to 1/3.  The m/n * pi factor is about the same, as m/n is approximately
1/3, but again the n^2 in the denominator causes the radius to go to zero
as n gets large.

It is well known that a disk of period n has n arms sprouting from the
branching Misiurewicz point near it.  The M-point for disk 1/2 is near
-1.54, giving 2 arms, one continuing left out the -x axis to -2, and one
going right back into the disk.  The M-point near (-0.1,0.96) is
associated with the 1/3 disk, and has 3 arms.  These arms can be labelled
by starting with the one coming out of the disk as arm "0" and moving
clockwise around the M-point.  It appears that, for the m/n disk, the mth
arm is the arm that "sticks out" the most, or extends furthest from the
cardioid in a direction normal to the cardioid.  Also, those arms (0 -
n-1) whose number is a multiple of m seem to be larger than the others.
These effects can be seen using the attached parameter file.  There are
zooms on 8 of the period 17 disks around the main cardioid.  (17 was
chosen because it is prime, thus for m = 1 to 16, m/n is in lowest terms
and will have an associated disk.  The disks for m = 9 to 16 are on the
bottom of the cardioid, and are the same as 1 - 8, except flipped about
the x-axis.)  In each zoom the mth arm (starting with 0 coming out of the
disk and moving clockwise) sticks out the furthest, and the multiple-of-m
arms are in general larger than the others.

Subject: (fractint) More Mandelbrot Fareys
Date: 31 Jan 1998 17:53:28 -0700 (MST)

A few days ago, I posted an article in response to a question about the
connections between the Farey sequence and the Mandelbrot set.  Since
then, I've found a few other connections, which I'll discuss here.

Recall that the Farey sequence is a way to order the fractions m/n, where
m and n are postive integers and have no common factors (like 1/2, 17/101,
etc.).  Each disk around the main cardioid of the Mandelbrot set is
tangent to the cardioid at the point corresponding to m/n turns, where 1
turn = 2 pi radians = 1 full circle.  Specifically, for the m/n disk, the
tangent point c is located at:

theta = m/n * 2 * pi radians,
r = (1 - cos(theta))/2,
x = r * cos(theta) + 0.25,
y = r * sin(theta),
c = x + i*y.

Also, the m/n disk has periodicity of n.

The sizes of the disks are also (approximately) determined by the Farey
number:  the radius of the disk (only the disk at -1 is a true circle, so
"radius" is used approximately) is

radius ~ sin (m/n * pi) / n^2.

For the period 2 circular disk at -1, m/n = 1/2, so the radius formula
gives sin(pi/2)/4 = 1/4.  Since this disk is a circle, the formula agrees
with the geometry exactly (the disk stretches from -0.75 to -1.25 on the
x-axis, so its diameter is 0.5 and its radius is 0.25).  (For the other
disks, the "center" is defined to be that point in the disk whose orbit
contains 0, and the "radius" is the distance from this "center" to the
tangent point.)  This simple formula also describes what happens near the
cusp.  As n (the period of the disk) increases, the disks get smaller.  In
the m=1 case (1/2, 1/3, 1/4, etc.), the size of the disk decreases with
n^3, which is why they seem to disappear into the cusp at 0.25.  Near
"large" disks, the surrounding disks also get smaller.  For example, look
near the 1/3 disk at the top of the cardioid.  On either side of it, from
2/5 on the left and 1/4 on the right, the disks get smaller as they lead
up to 1/3.  The m/n * pi factor is about the same, as m/n is approximately
1/3, but again the n^2 in the denominator causes the radius to go to zero
as n gets large.

It is well known that a disk of period n has n arms sprouting from the
branching Misiurewicz point near it.  The M-point for disk 1/2 is near
-1.54, giving 2 arms, one continuing left out the -x axis to -2, and one
going right back into the disk.  The M-point near (-0.1,0.96) is
associated with the 1/3 disk, and has 3 arms.  These arms can be labelled
by starting with the one coming out of the disk as arm "0" and moving
clockwise around the M-point.  It appears that, for the m/n disk, the mth
arm is the arm that "sticks out" the most, or extends furthest from the
cardioid in a direction normal to the cardioid.  Also, those arms (0 -
n-1) whose number is a multiple of m seem to be larger than the others.
These effects can be seen using the attached parameter file.  There are
zooms on 8 of the period 17 disks around the main cardioid.  (17 was
chosen because it is prime, thus for m = 1 to 16, m/n is in lowest terms
and will have an associated disk.  The disks for m = 9 to 16 are on the
bottom of the cardioid, and are the same as 1 - 8, except flipped about
the x-axis.)  In each zoom the mth arm (starting with 0 coming out of the
disk and moving clockwise) sticks out the furthest, and the multiple-of-m
arms are in general larger than the others.

There is a simple way to show that a curve may have an infinite length but
encloses a finite area. Start with an equilateral triangle and its
circumcircle. Then transform the triangle to have a Koch snowflake : the
Koch curve has an infinite length but it is surrounded by the circle.
Therefore, the area enclosed is limited.

Or look at an island : do you accept, as stated by Mandelbrot that the
length of its coat is infinite ? But the area of the island is limited.
