Subject: (fractint) Colors
Date: 01 Mar 1998 06:34:28 -0800

Hi,
Does anyone have a colormap they might be willing to share that wld create
the effect of a bug in amber? I have tried and I am unable to do this
myself, and now I shall go to bed; but it is discouraging to create images
that otherwise would be cool if the colors were right. So I'd really
appreciate it if if maybe someone cld at least give some general tips
toward getting these colors. I am Sylvie Gallet's triangle formulas and
using the Fractint color editor. And once again: the desired effect is: A
BUG PRESERVED IN AMBER.
Thank you.

<post scriptum>

I recently obtained a copy of Fractals for Windows. Now the authors of this
book are very enthusiastic about Winfract (this was circa 1991). However,
it is unclear what version of that program the book addresses, because the
installation program doesn't work Win95.
I considered playing with the current version (18.21, I think) available on
the Fractint page, but for seem reason this seems to be discouraged (it
says something like, OK, if you _really_ want it, here it is, but be
forewarned). Has anyone used this w/ happy results? Also if someone has an
executable version of the Winfract version that shipped w/ the book and
wouldn't mind sending it to me, or can tell me where I might download this,
I would appreciate that, too. My mail server allows huge binary
attachments. As a very last resort I wld re-compile it; however, I have a
relatively small hard drive and don't really have room to put my Borland
4.xx compiler back on. I'd have to delete somthing big, like Windoze.
Goodbye.

Mrvn wonders:
>What I now wonder is, if anyone knows how to construct a good

Well, I've done a little experimentation, and come up with a method for finding
the tangent points for all the buds off the main cardioid.  It is an iterative
process in that you need to know the tangent point of some bulbs before you can
calculate the tangent points of other bulbs.  Once again, I *intend* to have a
graphical description up on my web page by the end of the weekend, but I can't
promise this.  Below is the verbal description.

We will be concerned only with calculating tangents for bulbs off the upper
(Quadrants I & II) half of the main cardioid, since the bottom half is a mirror
image of the upper.  Consider that there is a series of largest bulbs off the
main cardioid, starting with the huge period 2 bulb, then including the period 3
bulb, the period 4 bulb, etc., where the next bulb is always the next largest
one to be found travelling in a certain direction along the edge of the
cardioid.   Let us call this first series A.

The procedure for finding the tangent point of any of the bulbs in series A was
described in detail in my last email on this subject... what we are interested
in is knowing the angle, which we'll call theta, to use in the procedure.  For
series A,

     theta = 360/p

where p is the period of the bulb in question.  Therefore, theta = 180 for the
period 2 bulb, 120 for the period 3 bulb, and so on.

But what about the bulbs between these bulbs?  Let's look at the period 5 bulb
to be found approximately halfway between the period 2 and 3 bulbs.  The period
5 bulb (which will be abbreviated as p5 from now on, to be read as 'the bulb
where the period equals 5') can be thought of as the largest bulb in *two*
'smaller' series of bulbs which consist of the larger, smoothly shrinking bulbs
on either side of p5.  The series extending clockwise from p5 consists of
{p5,p8,p11,...,p(3p+2)}, and the series extending counter-clockwise from p5
consists of {p5,p7,p9,...,p(2p+3)}.

Now, we need to be able to recognize these so-called series of bulbs because in
order to find theta for a bulb, we must know the tangent point of a bulb which
'bounds' its series.  For example, the p5 bulb's clockwise series is bounded by
p3, and its counter-clockwise series by p2.  Let's denote a bounding bulb as
b(p), and the angle theta for the bounding bulb as theta(b(p)) (note: no
multiplication is meant to be implied here - it is just a labelling method).
Using this notation, we can define theta for any bulb off the main cardioid as:

theta = theta(b(p)) +/- theta(b(p)) / p

The +/- will be a plus sign if the bounding bulb is clockwise from the bulb in
question, and a minus sign if the bounding bulb is counter-clockwise from the
bulb in question.

Let's work through an example or two.  As we've already determined, the p5
bulb's bounding bulbs are p2 and p3. To find theta for p5, we need to know theta
for at least one of these bounding bulbs; we have already done this above.  To
find theta for p5 using the p2 bulb:

theta = 180 - 180/5 = 144

Or, to find it using p3:

theta = 120 + 120/5 = 144

As one more example, consider p11 between our p5 and p3 bulbs.  What are p11's
boundary bulbs?  They are the bulbs which define the 'series' to which p11
belongs.  To determine this series, start with p11 and move along the edge of
the cardioid until a bulb is found which fits the description of a 'local
maximum' in regards to size (not period number).  Moving counter-clockwise, we
encounter the p8 bulb (which is larger than p11 in size), but if we move almost
the same distance again, we encounter p5 - this is one bounding bulb of the
series to which p11 belongs.  Looking clockwise from p11, the next largest bulb
is p3 - this is the other bounding bulb.  And because we have already figured
out theta for p5 and p3, we can find theta for p11 as either:
theta = 120 + 120/11
or
theta = 144 - 144/11

I will really try to get some graphics going on my web page this afternoon,
really!
Cheers, Jason

I discuss Winfract vs. Fractint in some depth at

http://wizzle.simplenet.com/fractals/hints/tips-fractint.htm

It's a perfectly good program, but it does have some limitations.  On the
other hand...for organizing files....particularly looking at color maps
with an eye to deleting some or renaming files....it is very useful, I find.

Subject: (fractint) 3d Mandexp fractals
Date: 01 Mar 1998 16:19:26 -0500

Can someone explain to me how I can make a 3D fractal, if I use "c= x + yi"
(the current point) and "w" is the third coordinate, and plug them into the
formula

"z(n+1) = z(n) ^ w + c"

It's kinda like sliding the mandexp set through a third dimension and using
that corrdinate as the real exponent component.  If this is possible, and
you understand what I am saying, email me back...

Thanks,

To all interested,

Ok, I've got a few pictures to help with my description of how to find the
tangent points for all the bulbs off the main cardioid.  I'm not sure where to
take it from here... I can see how the buds off the period 2 bulb might be
described, but what about period 3?  How does one describe the line which
represents the 'x-axis' for the period 3 bulb?  I'd check out relative areas of
bulbs, but I think this has already been done - anyone have two cents to add?

Anyway, For a mediocre improvement of my last couple emails on this subject,

<POST SNIPPUM>   ;)

I believe that lyapunov.map would be a good place to start.  The colors are
relatively close.  However, you might need to do a bit of cycling or actual
map editing to get it right, depending on what you're trying to amberize(?).

I have.  It's good for if I want to pop into Fractint and do a quick render
of something (like the Mandelbrot Set) at low-res so that I can play with
it in Photoshop.

I wonder if that actually was 18.21...  I haven't seen any updates to
Winfract for awhile.

Hi Tim:

I've noticed a problem with Fractint with regards to the number of
formulas that can be stored in one file. Because of this problem, I
limit myself to having no more than 100 formulas in a file. I discovered
that when I had somewhere around 150 formulas, the formula names listed
on the selection menu would run up against each other like this:
formula1formula2formula3 etc. It didn't matter how few characters there
were, the same thing would happen even if they were frm1frm2frm3frm4frm
etc. This problem does not occur with parameter files ot color map
files. Would you kindly rectify this snafu in FractInt20? I'd be
eternally grateful to you.

Sorry for the screwed-up subject line in my last msg.

Wow, Sylvie!  Awesome variant!  Now I need to get some work done.

Depends on what you mean by "3D fractal".  Can you be more specific?

I don't know if its possible yet, since I don't know what you're

I took a day off and...of course...fractaled...

In my browsings...I ran across this absolutlely delightful julia ......and
the pars below are a tweek on the original parameters.  Thanks to whoever
originally posted this julia.

Please please please.....when posting pars...identify yourselves on the
first line. I do so enjoy all the postings and would like to thank all the
contributors but am lazy and only look at the information visible when I
open the par.....that is limited to the name of the par and whatever you
feel is most urgent to say....to me...your name is tops!!! Hey....initials
are fine....avw is me. I want to be able to say thanks or whatever.

While the julias aren't original...at least my color maps are...and each
julia has a new wizzle map....enjoy.

Pete...

Les St. Clair recently posted some 3D fractals.....check out his awesome
site at

http://ourworld.compuserve.com/homepages/Les_StClair/

and he posted the pars for some of his 3D stuff here as well.  I think if
you download his pars.....and check out the documentation in fractint about
the 3D feature...you will be well on your 3D way.

I found the methodology pretty simple once Les got me going. I even made a
3D fractal of my own!!!  ((thank you les))

What are the units of the variable

If I want to swap re for im, I use flip but what
if I want to flip a picture upside down in the formula?
Do I write

1-Pixel

You can use the conjugate of the point variable -- you just replace every
instance of 'z' with 'conj(z)' (or whatever :)  )  This works because the
conjugate of 'a + bi' is 'a - bi', thus, every point above the axis is
mapped below the axis.  To flip it over the y-axis, use
'-conj(z)', which would change 'a + bi' to '-a + bi'.

Hi Wizzle,

Julias look like the region around the spot in the MSet specified
by the parameters. So in your post....

;^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
this is the location in M. Now you must zoom in until you see the 'same'
pattern. I have zoomed in to look for the midget. It is off a little,
probably
due to your not using floating.  So in the following I moved over a bit,
then hit space to get the Julia.  (I'm taking a break from the massive
testing
at work, the machine is rebooting.)

I'm rather annoyed...  I have several fractals I started in 1024x768x256
svga mode, and I want to run them in batch mode in the background in win95,
using disk-video...  But whenever I run them, fractint uses the svga mode I
used when I saved them.  Does anyone know a way around this?...

The Julia set image has to have all the features seen around the
parameter spot in the Mandelbrot set.  So at lower magnification
in M we have the following (see par). This shows up first twice then
four times in M when we zoom in. And so it also does as we zoom
into the Julia. You chose a zoom that shows the four fold and so it
looks squarish.  Try this par at all zooms into the midget. Then
press space twice and watch all zooms in the Julia. See the
same sort of 'stuff'.

I'm using something like this.

w=Pixel
c=transformation(w);  transformation involves exp and other stuff,
                ; very nonlinear.
z=0:
  and then the usual Mandelbrot like iteration

But I'm trying in the w= step to get the upside down of the image.
I tried w=1-Pixel and since the image is centered at 2.5 I try
w=2.5-real(Pixel)+imag(Pixel)
but I usually get black screen, not what I expect.

This is exactly my situation. The limit of 2000 is built in, but Bob
is getting a bad failure much sooner. Unfortunately, if I can't

I suppose negative results don't prove anything but in the Orgform
compilation Bob Carrs formulas list perfectly up to about a thousand. I
would have to give Fractint a high score on formatting the results to fit
the longest name in a collection. It worked as well with one of my
collections that had 200 entries with much longer formula names.

Peter,

You need to make sure you have the 1024x768x256 disk video mode specified
in your fractint.cfg file.  For simplicity, I'll assume that it's invoked
by "af10" (alt-f10).  Then, you should be able to regenerate fract001.gif
which was started with 1024x768x256 svga, by running the batch file with
this command in it:

fractint filename=fract001 video=af10 batch=yes

If that doesn't work, save the offending parameters to a par file, and
either specify "video=af10" in the par, or in the batch file, as above.

Date: 01 Mar 1998 22:27:13 -0600

I have uploaded a massively revised simplgif program to

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

I'd appreciate hearing results of any testing, and which executable
is better.

Included are executables compiled with MSC (large model) and djgpp and
the C source. I haven't tried, but I would expect the source to
complile with minimal problems under Unix.

I did some editing of the encoder and decoder sources, mostly
unifying some typedefs and "ansifying" the old K&R style. However, I
felt it would be unwise to edit the reliable encoding and decoding
sources too radically. Given the variable quality of GIF sources, I am
really happy with the compress encoder and Steve Bennett's decoder.

This version has a new decoder, basically the same one as in
Fractint.

Let me know if you have any suggestions. The buffering scheme used in
reading and writing the tempory file is the same as in the original
simplgif by Bert Tyler. This could be made more efficient. I made a
start at eliminating signed 16 bit integers in favor of unisgned, so
that simplgif would work with 64K rows. I doubt this is complete, so
most likely the limit is 32K.

One "possible" problem might be one I've had alot of trouble with.
Look for the color area in the PAR, if it's double spaced that won't
read in properly with FRACTINT.

Example : <This is jiberish so don't try to run it>

color=675dfgf8787tolk9o9898g979g97gf

<7889787875875jk897gf>897897f87f<86

 9867ihv8ycfuiovuivyuiv9

The last line might need that gap as it's first character (as we all
know computers read empty spaces as actual commands or command
structures) but combine the lines like below and it should work.

(note it's still jiberish, just an example)

color=675dfgf8787tolk9o9898g979g97gf
<7889787875875jk897gf>897897f87f<86
 9867ihv8ycfuiovuivyuiv9

Hopfully I haven't left you more confused, if I Did sorry.

Getting from a message to an image drawing on your screen does take a fair
amount of knowledge of how Fractint works.

   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 ASCII text files with entries in 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 originally 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 contained in messages should be copied to a DOS text

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 "}"). Don't delete the original message yet 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 DOS text file with the extension ".frm".

Any name is OK, such as "1998msg.frm". 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".

What I *meant* to say was:
 please just send the URL or book/article title (to the list), as
 opposed to the article itself.

I'm sure the subject would be of general interest, I just didn't want
to waste bandwidth with a post of the whole enchilada.

George,

Thanx for the explanation. It was somewhat drawn out, but I got what I asked
for. I've been using Fractint for quite a while, but not very intuitive
about converting the posted files into what Fractint can use. I know how to
use Fractint, just not how to convert the e-mail ascii text files so that
fractint can use it. Now I do. I like the 'one button functions' such as the
ones you mentioned: 'z' 't' 'f6'...tc. I've downloaded the new program
a long while back. Quite an innovative program. But since I'm going to
college, I don't have much time to really get into fractals. But I try.

I have over 30 pictures printed on my Epson on coated paper (gets kinda
spendy after a while), and they are fantastic. I made most of them,
using other people's formula files. I do not know how to make my own
yet. Most are not posted on my web page yet. Haven't even added them to my
par file yet either! I hope to soon though and then post my par on here if
everyone likes.....as an attatchment, not an ascii text add-on to the
message. That's just so that newbies can just save the attatchments instead
of going through the hassle of changing and copying that I am going through.
^_^

Well, I've gotta get to studying some chemistry. ACK! But I'll be making
more fractals when I have free time. I did however, find something
interesting. The map maker by Ron Barnette can make maps for other programs
too. I used the maps on my Winamp (mp3) player plug-in and it worked fine.
Thanx again Ron! Outa here!

Happy Fractineer ^_^

But I like boring the whole list :)

Actually, raising complex numbers to a fractional power is not as
tricky as it sounds.  A complex number in cartesian coordinates (ex
3+4i) can be converted into a polar form (magnitude=5, angle= ~.972
rad in this case).  You can also write this in the form m*exp(i*t)
where m is the magnitude and t is the angle theta.  This is because exp(i*t)=cos(t)+i*sin(t).

Raising this to any power (whole or fractional) can be done:

z=m*exp(i*t)

z^x=(m*exp(i*t))^x
   =m^x*exp(i*t*x)
   =m^x*(cos(t*x)+i*sin(t*x))

Raising a number to a complex power can be done by remembering that:

z^(a+b)=z^a*z^b

Now all we have to do is figure out how to raise a number to an
imaginary power.  I can't exactly remember how do to this right now.
Perhaps someone else on the list will pick up the baton.

I now remember how to do this as well.  If l is the natural log of the
magnitude, then the number can be written:

z=exp(l+i*t)

so

z^w=exp(l+i*t)^w=exp((l+i*t)*w)

So this just becomres a case of multiplying the complex exponent w by
the log of z (l+i*t) and then exponentiating.



Ah, this is a great discussion, I'll have to go out and get the latest
fractint copy.

Hi Ocie,

It is good to see you posting again after so long. Now, about a week ago
we were discussion ASCII Mandelbrot sets and I noted a few sources.
One was you post to sci.fractals in 1993 (or there abouts).  You posted
a new version

ftp://ftp.inria.fr/graphics/aamandel-2.1.shar.gz
Now this, unlike your earlier version does not compile on my compiler -
missing headers etc. So could you install a DOS executable on your web
site?
Since your first version is really portable, you might consider posting it
as well.

My second version had an "interactive" mode which lets the user select
the area to zoom into.  I'll see if I can turn this off gracefully if
there is no curses library.  Don't know about a DOS executable, but I
should be able to at least release sources that will compile under DOS.

Jay...

Thanks so much for the explanations and samples!!  I feel like you gave me
a brand new wonderful toy to play with. I'm having such fun finding julias
and minibrots.....I never realized they were there.

One more question.....I figured out that zooming out takes me back to the
mandelbrot set......and when I zoom out from the julia I can see the little
"strings" along the mandelbrot set that contain the julias even at a fairly
low magnification (like looking at a large portion of the "lake").
However, when I start with the mandelbrot set in fractint I never seem to
see those strings no matter how much I zoom in. Why can't I see these
strings when I start with the mandelbrot set and yet I can if I start with
the julia I posted?

i hope someone can help me as i have not had fractint for several weeks
now.i had to replace my video card and installed a Diamond Speedstar 64
2000 graphics card.my computer is a ibm clone 486 66 mgz and i have
fractint 19.5.i can only view fractals in the most primitive modes.i
have always used the shift7 1024X780 video mode that works with most
svga.i have no idea where to go from here to get this working.i have
read the fractint documentation on video modes over and over but it is a
little over my head for me to fool with i believe.has anyone had this
problem or can anyone advise me of how to get the sharpest images
possible with this video card?i have had fractint since version 16 and
was one of the programs that amazed me and sparked my interest in the
computer.i am just a lover of fine images and do not really know anyone
else with an interest in fractint like i have.hope someone can help!!!

There are about 20,000 more posted on my web sites.  Glad you are
having fun.  There is a lot to learn about the old Mandelbrot set. I've
been spending uncounted hours (actually, I think my wife has been
counting the hours) ever since I got my 8086 with CGA in the '80s.  I
used to figure 2 hours to make a nice 320x200 image. It now takes
2 seconds.

little

"strings",  that is an example of the 'stuff' mentioned above.  Stuff in
elephant valley looks like elephants. Stuff in seahorse valley looks
like seahorses. Stuff near the base of the period 3 bud (big one on top)
look like 3 armed galaxies.  Julia sets with parameters set to these
regions will have that look to them.

-low magnification (like looking at a large portion of the "lake").

And where do we find strings?  Out on the spike, because it is the
mother of all strings.  These start showing up anywhere more
negative than -1.  Near -1.25 they are clumpy and are called scepters.
Your example is out at -1.75 where strings are going strong.

Twiggy strings are found near (-.134, 1) because that filament is
- you guessed it - twiggy.

Rumor has it that Dr. J is building new wings to his laboratory, new
ones for each of these regions.  Word is that he stepped into
a particularly tangled mess of 'strings, barbed wire and quick sand'.
I'm too busy running tests at work tonight to look after him. He is on
his own.   :-)

Maybe there should be an award, like  "Fractal of the Year"
or a grammy or a Bammie or something.  I nominate
Mark Christenson for  "gravijul".

Thanks for the praise, but the year is *very* young.  And the
competition is stiff.  One of the great things about this list is the
way it enables collaboration and cross-fertilization at light speed;
I know it has made *me* a better fractal artist.  I haven't had time
to explore Sylvie's gravijul-v3 yet; and while v2 seems a bit less
fertile than the original, its potential for unusual structures
(especially periodic "tiles") is really stunning.

Here's another v2; it's basically "Internal Reflections" on steriods,
with a precious metal finish.  This color map (called "sil&gold") and
the one I used for "I.R." (called "circus") are two of my new faves
for decomposition images (I'm also on a decomp jag, as you may
have noticed).  Hard to believe I got along for 10 years with only one
option, color=iter (it was all I ever built into my programs).
Note: Both images/maps are also great for color cycling!

Thanks for the run-down.  Guess I gotta shake out the cobwebs.
It all made sense, but things like coordinate system conversions
and identities are quite foreign now, having not been used since
college (cripes, 1979?!?).  I'm pretty certain I couldn't do integration
by parts or substitution to save my life.

Date: 04 Mar 1998 07:50:52 -0800

How come if I start with the julia formula I can't find any mini-brots no
matter how much I zoom.......if I start with a mandelbrot with "stuff"
(those strings....which I still don't know where they come from).....I
don't have any trouble finding lots of minibrots among the julias on the
"stuff".

Where did the mandelbrot with "stuff" come from to begin with? And how do
the coordinates work? Is the middle of my screen ground zero in the
mandlebrot? Up and to the right is plus.....down and to the left is minus?

Can I input coordinates somewhere?

Bud....the sil&gold map is truly excellent and I love what it did to your
image.  I thought the original lovely in a "painterly" sort of way. This
new variation has such a different feel....much more 3 dimensional.

I've had a wonderful time with all the gravijul variations. For some
reason, crosses and mandalas keep coming up for me.....must be a "sign"
that I need to update my gallery for Easter/Vernal Equinox. Thanks you so
much Buc and Sylvie.

Hi!

        As I had an expecial interest in the Bifurcation Fractal and the Bifurcation Lambda, I got contact with the Feigenbaum number, which is good covered at the address below:

        http://www.stud.ntnu.no/~berland/math/feigenbaum/index.html

        Some days ago, however, I've found a little and "simple" program that calculates the Feigenbaum number.  Although I've understood how the Feigenbaum number is calculated based on the Bifurcation Fractal design,  I've passed many days trying to compreend how this program works, but I couldn't...

        So, I would like to ask if someone can help me to understand the logic of this code that I've attached to this message.

Thanks in advance,
Daniel Sadoc

Hi!

        I've bought the book Fractals for Windows (from Wegner, Peterson, Tyler and Branderhorst), here where I live, in Brazil, and since than I'm very interested in fractals.  I've just got some experience with the WinFract, which I really appreciated.

        I've been reading some very interesting messages from this mail-list, and now I have a question, which I've sent in the following e-mail.

        I expect that I can contribute to the growing of this list.

I've been totally unable to get diskvideo to work in batch mode, short of
making another fractint.cfg containing only the diskvideo mode I want.
Could someone tell me how I can continue an image I started in regulr

sstools.ini and fractint.cfg?

Subject: Re: (fractint) minibrot question
Date: 04 Mar 1998 12:28:41 -0800

Hi wizzle,

The Mandelbrot set is a Map of the Julia sets for the iteration
equation, any iteration equation. It is showing us the convergence or
divergence results we shall see (an image of results vs. c)  if we
make a Julia set. The Julia set image shows us the
convergence or divergence using different initial z0 values.

If we want to see midgets in the Mandelbrot map, we must use
z0 = a critical point. That is why we use z0=0 for the classic MSet.
Given that we use z0=critical point, we will see some midgets
(depending on the iteration formula).  In the classic MSet, all the
midgets are connected by smaller midgets and other 'points'.

These are the filaments. The pretty stuff we see are there because
there are midgets all lined up in some organized pattern. Now the
Julia set explicitly avoids the critical points (except for a few samples
in the z0 plain that happen to be critical points). So you don't see
midgets.  If c (the parameter for the Julia set) is in a solid part of
the corresponding Mandelbrot map, we shall see solid parts (non-
divergent) in the Julia set. Why?  Because where that z0=critical
point is, there at least, the iteration does not diverge. (It is in a solid
part of the MSet and so it must be a solid part of JSet. It is after all
the one point belonging to both.)  If this point is well inside a solid
component of the MSet, like in a bud, then for some region around
it in the JSet we shall see it is solid (non-divergent).

If the point is not in or next to a MSet component, the point diverges
and none of the JSet has a chance of converging. The JSet has no
solid parts.

If you put c in the 'center' of a midget's cardioid, there will be a
circular solid spot in the center of the Julia (at the critical point).
If c is in a bud center, there will be several solid parts in JSet
corresponding in a sense to the period of the orbits.

Hope this helps,

Jay

The coordinates are the complex number plain. If there is a rotation or
skewing then it gets messed up (but prettier for an image).

Press 'z' and 'F6' to see the coordinates of the screen center.

Yes.

Yes. In the 'z' F6 screen you can change center and zoom, etc.

comment { commentary and pars by Mark "Bud" Christenson 3/4/98

Having played around with Sylvie's gravijul-v2 some more, I now
am totally in awe.  I have about 30 images, and the hardest part
is coming up with titles.  Here are four (you should be thankful I
don't dump more), all rendered in sil&gold.map.  Hey, it works
for me!

Subject: (fractint) Two Fractint questions
Date: 04 Mar 1998 18:55:27 -0800


Hi folks,

I have two questions.

Question 1: I have a formula which is axis symmetric so this should work...

frm:Colorit1234   (XAXIS){


But it does not, the images computes top to bottom BUT if it is put this in

the par file

  outside=summ symmetry=xaxis periodicity=0

the images draws from top/bottom to the center - twice as fast.
Why does the frm version not work?  Also, if it did work, and I used
inverse, the symmetry would go away. How would the formula
know I had a non-symmetric image from a basically symmetric
formula? So is it ever a good idea to try to get the formula to have
a working symmetry instruction?
Oooops, that is more than one question.....

Example from Fractal of the Night
http://home.san.rr.com/jayrhill/FotN/FotN60.html

frm:3telescope (XAXIS){ ; (c) Jay Hill, 1998
; use outside=summ periodicity=0
done = 1, z = 0, zc = 0, c = pixel
s=|c|, t1=(256*s - 96)*s + 32*Real(c), t2=16*s + 32*Real(c) + 16
B=sqrt(-4*c-7), t3=|8+4*c*(1-B)|, t4=|8+4*c*(1+B)| ; component tests
z=z + 249*(t1<=3) + 250*(t2<=1) + 251*(t3<=1) + 252*(t4<=1) ; set colors
if(z>0) ; for periods 1, 2, 3.
done=-1 ; color is set for c in a component, skip iterations
endif
: ; initialization.
zc=sqr(zc) + c ; standard MSet iteration
if (|zc| >= 4) ; Bailout at 4
done=-1 ; Set flag to force an exit.
endif
done >= 0 ; Continue if the flag >=0.
}

Normal_MSet123t    { ; (C) Jay Hill, 1998
                     ; uses tests for components periods 1, 2, 3
  reset=1960 type=formula formulafile=Colorit4x.par
  formulaname=3telescope
  center-mag=-0.75/0/0.6666667 float=y maxiter=256 inside=249

  wdLwcMwcMwcM<90>wvuwvvwvvwwwwwvwwu<\
  51>ee5eKwKdwUUwZF5KUAc0KwwcwwweeLLLC
  }


Question 2: Is i=sqrt(-1) a constant in Fractint. It looks like it is not.

Should it be in a later release?

Jay
PS It looks like questions can be fractal, that is, upon closer look
they are more than one question!

Subject: (fractint) Carlson-Gallet formula
Date: 04 Mar 1998 21:08:28 -0600 (CST)

A couple days ago I sent this formula and the first par to
Sylvie because I wasn't satisfied with the colormap I was
using and I wanted to see what the image would look like
after Sylvie worked her magic on it.  Sylvie not only sent
back five colormaps but also added several optimizations
to the formula.  Not wanting Sylvie's other four colormaps
to go unused, I've included four more pars that zoom into
different areas.

Subject: (fractint) anybody try simplgif?
Date: 04 Mar 1998 21:37:58 -0600

A while ago I mentioned that a new version of simplgif is available
at:

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

This utility combines the images in multiple-image GIFs created with
Fractint's "divide-and-conquer" mode.

Just curious, is it bug free or have folks just not gotten around to
trying it? I'll tell you a secret if you promise not to tell. If
you add the -i option to the simplgif command line before the
filename arguments, it will produce an interlaced file. But no,
Fractint doesn't read interlaced files correctly yet <g!>

I have Fractint working successfully on a PII 233. However, about 75% of
the time when I exit Fractint (after using it in full-screen DOS mode) I
at once get a message that Windows Explorer crashed, and glitches appear
on the desktop. I can still do things, and don't have to reboot, so this
isn't a crisis, but it is a bit of a pain.--Alice

It's easy for us English speaking people to understand what you wrote

Tim,

I tried the simplgif.exe file and it seems to work fine. I only have one
remark. I'm missing the line counter (present in the previous version) at
the end of the program (after constructing all the partial images into the
final file) so I don't know what progress the program is making at that
point. It's very useful when making HUGE gif files.

Excellent guess! Right on the money! You didn't do this with babelfish, did you?

In a manner of speaking. Left Asia 1,100 years ago.

Did you try removing the space between the formula name and the

I don't believe it is; all the constants that are defined are listed
in the helpfile.  I think its in the section on type=formula.  If you
need "i", just use flip(1).

I thought I'd pass on a lesson I learned from exploring Sylvie
Gallet's gravijul-v2.  I first noted that it had less variety than
the original formula, because I was getting a lot of blank screens.
After finding fractals that worked better with absurdly low
bailout values (between 1 and 4), I started my scans again.
To my amazement, function combinations that did nothing
before produced incredible tiles!  So before you give up on
Fractint sub-type, try a low bailout value.  You *will* get a
degenerate case with very low iteration counts, but that
can be an asset for "decomp" images (pixels that bail out in
the first cycle produce the characteristic "fan" structure
prominent in most of my images based on gj2v).

Also, if you want to concentrate on producing tiled images,
start your search with fn1 set to any of the periodic functions
(sin, cos, tan, cotan).  There are exceptions to this rule,
but these funtions will produce most of the tile families.


Happy hunting, Bud

Subject: (fractint) Fractint as prototype society
Date: 05 Mar 1998 13:14:17 -0500 (EST)

I had a hard time finding Fractint on the Web; lots and lots of people
have pages about their use of it, few of which have links to the
`official' home page.

When I found the home page, I was a little disappointed to find that it
was still at 19.6 -- the last version I'd used was 19.2, I think, a few
years ago.  I feared that Fractint had died.

Imagine my surprise and joy to discover this mailing list!  Ten or
twenty messages per day, all of which are relevant, many of which are
really cool fractals, with twenty-nine different posters in the last
two days -- including Tim Wegner!

It looks like Fractint is far from dead after all.


My interest in Fractint is partly because it can produce extremely cool
pictures, and partly because it represents an extremely cool
sociological phenomenon, one that has the potential to change
everything about our society.

Fractint was built by an enormous group of talented volunteers, most of
whom contributed only a few hours of their time.  But because of
computer networking -- specifically CompuServe -- they all benefited
from the sum of everyone else's work.  And Fractint ended up being the
most featureful fractal software you could get for any price, as well
as an exemplar of excellent user-interface design, and having a set of
graphics-adapter drivers to rival any commercial graphics program.

This phenomenon is made possible by the zero-cost reproducibility of
computer software.  It means that you can get much more out of a
program than you ever put into it -- in fact, most people put in
nothing at all.

In more recent years, Linux and FreeBSD have done the same thing, and
they are certainly the best operating systems available for any price.
They're not exemplars of user-interface design, but that is rapidly
changing, now that that's something their users care about.

In the near future, I expect that automated fabrication technology will
make many goods much more softwarelike.  Material objects will cost
money to manufacture approximately in proportion to their mass, at
perhaps a $1 to $10 per pound.  The difficult part will be designing
them and propagating good designs.

I expect that we'll all have Stone Soup cars, televisions, and
computers, if we can figure out how to make it happen.

So Fractint is a compelling experiment in the possibilities of social
organization.  If we can figure out what elements made Fractint such a
roaring success, and duplicate those elements in other projects,
-- we can make the world a better place for all of us.

So I'd like to hear what everyone thinks about
- why Fractint was such a success
- what other projects they've seen that worked similarly
- what's happening to Fractint now?  Has it reached perfection?  :)

Some thoughts on these issues, for those who are interested, can be
found in the latest issue of First Monday, at
<URL:http://www.firstmonday.dk/issues/issue3_3/>.  The most influential
of the papers therein is Eric S. Raymond's `The Cathedral and the
Bazaar', which is also available at

Immediate perception: the fact that Fractint _is_ free, and the fact that
its source code is distributed equally freely, with contributions welcome
from all quarters. I might suggest that the sort of people who would be
interested in generating fractals are more likely than most samples of the
human population to be the sort of people who would be in a good position
to contribute something program-wise. Just check out the number of
programmers on this list.

>- what other projects they've seen that worked similarly
Off the top of my head, I can think of POV-Ray - one of the best raytracing
programs I've seen, comparable in quality to many commercial packages.
Funnily enough, there's a not insignificant overlap between Fractint
programmers/users and POV-Ray programmers/users (our List Administrator is
one himself).

>- what's happening to Fractint now?  Has it reached perfection?  :)

To answer the second part first: NO! NO! NO! :) It still can't do realtime
animated quaternion Julia cross-sections, for a start!
To answer the first part; stay tuned to this list!

Note: this is particularly important for functions that
always return values with magnitudes below 1, such as
sine and cosine.

You can restart Windows Explorer by hand if you have, say, File Manager
open.  Just do File|Run|Explorer.

My NT4 machine at work restarts Explorer automatically whenever it
crashes.  Also, on NT, you can do control-alt-del and get Task Manager
-- kind of a gussied-up Task List -- and you can do a "New Task" with
it to restart Explorer.  I don't know if 95's task list lets you do
this, though.

Oh, well.  Soon, we'll all be running Linux, so it won't matter anyway.

On rereading my message, I realize that it sounds like I don't
understand the problem.

Presumably, you would like it to not crash Explorer, and since you
`don't have to reboot', it's possible that you already know how to
start Explorer manually :)  (Or perhaps Win95 restarts it
automatically.)

We could have an actual FAQ, Frequently Asked Questions.  For an
excellent example of the genre, see Marshall P. Cline's C++ FAQ at
<URL:http://www.cerfnet.com/~mpcline/c++-faq-lite/>.

There are tools that will help you automatically generate such
documents; the former Linuxdoc-SGML (now called by a different name...
sgmlsomething) and LaTeX are two.

  Nope. Not until it can calculate images at zoom levels of 10^(10^12) in five

>If you need "i", just use flip(1).

The most efficient way to represent "i" in a formula is "(0,1)". The
complex constant will be set up before the formula image starts drawing,
and thus does not entail a separate operation during the running of the
formula.

Rich,

>The parser might be sensitive to whitespace.

The parser ignores all white space, except that a blank signals the end of
a formula name (or a par entry, for that matter). Thus a formula named

this is good {}

would be read as having the name "this". An open paren or open brace also
signals the end of the formula name if no blank space has been reached.
Blank spaces, or lack thereof, between the formula name and the symmetry do
not affect the way the formula name, symmetry, and content are read.

OK gang, the collected pars from this list for February can be downloaded=

from my web pages at:

You'll need to get the updated formula file too.

I have a copy of the book. I _think_ I have produced something similar, but
did not care for it, so did not keep it. I think it was in Lyapunov...


The coloring of the cover (gold/black) is good, though.

Last time I looked up the formula stuff, it wasn't obvious you could
write complex constants.  Is this only for constants, or can I write
"(imag(z),real(z))"?  (This is admittedly a contrived example, since
that expression is equivalent to flip(z).)

Hi, Peter -

>>Has anyone  seen the cover of Exploring Chaos (edited by Nina Hall);
that's the effect I want but can't get.<<

My baby is still in the shop, and I'm still on cortisone, and feeling
suicidal in general.  So I just woke up to the fact that you are looking
for an amber colormap, and there are some GREAT formulas called
gravijul-this-and-that floating around out there.  I haven't seen the cover
you reference, and I don't know if this map will do it or not, but I hope
it helps.  You may have to make some alterations to get it to "fall" right
on the specific fractal you are working on.

In keeping with the group's decision that attachments are unwanted, the
specifics follow:

Enjoy!  Linda

A complex constant must be in the form open paren, number, comma, number,
close paren, e.g. "(2,-4)". The example you gave should give an error
message (it will for sure in the next release, because I just rewrote the
error warning code about a week ago to make sure it does).

I have a copy of the book, and these two images, although not created
with Fractint, can be loaded into Fractint and the colormaps saved.  I
think the colors may be close to what you want.  These URLs will
download the images directly from the web.

I haven't seen the cover, but the attached par file draws
an image with the effect I think you are after.  It looks
especially interesting in the LL and UR corners.

There's a freeware Unix text editor called Nedit, which is maintained
by a chap in Fermilab named Mark Edel, which is run in a somewhat
similar way.  (It's at:

                 ftp://ftp.fnal.gov/pub/nedit/v5_0_1/

              )

I believe Mark has some sort of 'official' responsibility for the program,
but many people have contributed to its present state.

It is freely available as source, and one of its features is syntax
highlighting for many different languages (I wonder if I could do one
for Fractint formulas and pars...?) and the macros are a popular area for
contributions, as are operational macros.

Being Unix, and available as source, there is much folklore about how
to compile on platform X with Motif Y...

(on topic again!) I like the idea of a colourmap competition, but the
temptation to start from a palette by one of our artists would be
very strong!  Maybe 'sealed entries' should be sent to a referee by a
certain date, and reveal all entries the next day?

And since someone mentioned using an existing color map to try getting the
result Pete described, I also am posting my b2golds.map which was my point
of departure........if you compare the maps you will see what vastly
different results are obtained.  I haven't had a chance to look at any of
the other "bugs" yet.

P.S. I had the opportunity to see the Amber Room in the Catherine Palace
outside St. Petersburg last year.......fabulous!!!!! even though it isn't
restored yet. There were entire panels of amber in the most glorious
colors.  That image was in my mind when I did my version.

Good idea, too. But, maybe, instead of just a contest this time, some of
the more experienced users would consider constructively criticizing the
entries so we could learn something from it. I think a good image to use
would be one of the Mandelbrot Novas on Paul Derbyshire's web page; the
first one in particular wld serve, I think, as a good coloring litmus test.

Here's something a bit more in line with Peter's request.

Also, a note to Stone Soup: Please consider adding Sylvie's
outside color technique to v20 (if possible)!  Most impressive!
The two "z" screen variables are great, but would be difficult
to assimilate into the current system, which takes no parameters.

I took me a while to get my act together, but here's a version that
should work (no, I haven't tried it yet).  Apologies to all put the
imaginary component of p2 to good use, but something had to go.
I let cold, hard science be the judge.  A survey of pars from the
list (excluding my own) indicated the following uses:

both: 5
real: 4
imag: 2
linked: 1 [real(p2) = imag(p2)]

Therefore I kept only the real component of p2.  Just so you know
I was democratic about it.  The new knobs are imag(p2) and real(p3),
with bailout as imag(p3).  p1 and real(p2) can be used as before.
Sorry the new controls are real-only, but the Fractint gods couldn't
have foreseen our parametric avarice.


Hoping this is another winner,
Bud

        The welcome message said, in part..."...but so are beginner's
questions, so don't be shy....."  etc.
        Joined the listserver about ten days ago and have been reading all
the messages that are being sent out. WOW!!! Am I over my head. But first....
So you know what, how, etc. - Am an old man, 77.  Got my first computer in
'83 - an Apple, of course.  Used primarily for word processing, some music
with MIDI and an elec keyboard, and playing games with my grandchildren
        About three years ago changed to IBM clone.  Rudimentary model.  Was
given, for birthday, I think, two books, "Wrinkles In Time" by George Smoot
and "Chaos" by James Gleick.  Both were extraordinary mind-blowers.  Because
of the piece in 'Chaos' about Benoit Mandelbrot I became fascinated by the
idea of fractals and spent about six monthes trying to track down a means to
do it or them.  (Incidentally, I am not only NOT a mathmetician nor involved
in science in any way, I am singularly poor in all things mathematical, I am
only an interested bystander, fascinated by the entire life and living
process but am singularly interested in art - shape, form, color - the whole
kit and kaboodle.
        I have now been generating fractals for about two years but only on
the most rudimentary and freshmanic level.  Not only do I know so little
about the process of fractal generating but also am STILL, AFTER ALL THESE
YEARS, a dunce with computers. So...."  Interruption. Have been called to
dinner by "..She who must be obeyed...."  Will be back with this, shortly.
                Sorry for the interruption, and thanks for your patience.

    I've loaded the available parameter collections from Les's webpage
onto the Spanky database. You may (or may not) find that you can
download from there if you have problems with Les's site. I think
Les's webpage should be everyones first choice for downloading these
formulae. He is after all, the one doing all the work, and his site
will always be more up-to-date.

    I will keep them there if this is alright with Les and as
long as everyone acknowledges him as the person who has done the
great job compiling them.

    You can find them for now at:

    http://spanky.triumf.ca/pub/fractals/params/
and put the formula file in

    http://spanky.triumf.ca/pub/fractals/formulas/FML_FRM.ZIP


    Cheers,
    Noel Giffin

    P.S.

    Let me know if this is okay with you Les.

Subject: (fractint) Texture and Inflation Formula
Date: 06 Mar 1998 19:15:50 -0600 (CST)

This formula and pars explore four areas of the classic
Mandelbrot set using a rendering method that creates, in
pars mndatm01, 03 and 04, images with a nice "texture"
that almost make you want to run your fingers over them.
Par mndatm02 creates an image that looks inflated (makes
you want to stick a pin in it).

The fractint newgroup generates a lot of mail and threads such this, in
my opinion, are just unnecessary clutter.  Please have consideration for
those with limited email access.

Carolyn...

Welcome!!!  Many of the things posted to the list I don't have a clue about
either.  I'm part of the "pretty picture" contingent.  But I do have a web
page with lots of VERY basic information.  The info that got me going was
Linda Allison's lessons....you will find the link at

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

I'm going to re-organize my hints and lessons, including a section for the
q&a postings from this list, this week end (she says...sure!!!  maybe). I
think Fractint is wonderfully documented, but examples helped me at first
soooooo much.....and that is where a web page can fill a gap.  Besides, we
all learn in different ways.

Anyone else with lessons type pages posted...please email me the url

[e-mail]

ciao

Yup yup...works great!!!  Another gravijul winner. In thanks, I've modified
your sil&gld map in the second par by replacing the red with teal.....

wizgravi2          { ; wizzle 3/6/98 from Bud's new formula
                     ; and a gift of teal for bud's fav map too!! budteal.map

  }

Hint for anyone else....bud's map will look great with endless variations
if you leave the silver and gold as is and fiddle with the other two
colors....try purple and green....magenta....oooooooorange......browns...go
for it!!!  Just remember to find the darkest versions of the other colors
and replace them....then find the lightest versions and replace
them.......use the old = and voila!!! new map.  Bud's map has black (r0,
g0, b0) in strategic places.....don't cross those boundaries.

Have fun!!

Subject: (fractint) .par & .frm files
Date: 06 Mar 1998 22:35:54 -0700

        Hi Linda

        Just left your Gumbycat page and down-loaded the .par and .frm
instructions.  Had to.  Otherwise too much for old brain to remember.  It
was an enormous help, but brought two questions to mind.  (Far more than
two, but two is all that I can handle right now.)  In order to save the two
files, do I have to type them all into a directory - or is there a way to
use the existing typed paragraphs?  Second question;  can I down-load the
color-map instructions - and if so will the B.G. black come out all black,
or will there be some kind of transformation that I know naught of?
        Enormous help, in that all of a sudden I realize just what the two
phrases refer to, and ALMOST how to use them.
        Thanks a lot.  A whole bunch of fractals worth.
                                        Ray Montgomery

I was so glad to read that I am not the only "Granny" on
this list. Since I saw my first fractal I have been fascinated
by the amalgamation of science and art that they represent,
the ideas of visible mathematics and colour, and that first viewing
 was a long time ago. My study of maths was limited altho' science
interests me greatly so I have been very grateful to the many listers
 who explain the various concepts, altho' I don't C  but QB.
Thanks  to you others who got me out of lurkdom
Cheers ,Pat.

Hi Noel,

>>I've loaded the available parameter collections from Les's webpage
onto the Spanky database.<<

>> P.S. Let me know if this is okay with you Les. <<

That's fine by me, placing them on Spanky is an excellent idea. The reaso=
n
for doing the compilations is just to keep these fine postings for
posterity (of course, if I get new visitors to my fractal pages that's go=
od
too!  :)

There seems to be a surprising number of people who subcribe to this
newsletter who are very new to fractals and Fractint.  At my website's Links
page, I have a step-by-step tutorial that can be downloaded that can help get
any beginner started with Fractint.  Please stop by and check it out.  No Math
Required!

Subject: (fractint) Fractal Formulas
Date: 07 Mar 1998 13:02:16 -0600

Hi Team Fractals:

Recently I downloaded an important fractal technical/reference paper
from the Internet that was chock full of formulas and other reference
material. I've excised all but the formulas that one can use in Fractint
(and other fractal programs) formula writing. If you're interested in
downloading the entire paper--it's 23 pages of 8.5 x 11-inch paper--surf
over to http://www.lifesmith.com/technical.html#anchor254229 .

Happy formula writing!

Bob Margolis

============================================================



                   Important Formulae for Complex Numbers

1) z = x + iy where x = Real part of z and y = Imaginary part of z

2) c = a + ib where a = Real part of c and b = Imaginary part of c

3) z = re^iq = (sqrt(x^2 + y^2)) (cos q + i sin q)
where q = arctan (y / x), r = sqrt(x^2 + y^2) and "sqrt" means square
root

4) z^n = r^n*e^inq = (sqrt(x^2 + y^2))^n (cos nq + i sin nq) ; r and q
as
above

5) sqrt(z) = (sqrt(r)sqrt(e^iq)) = (sqrt(sqrt(x^2 + y^2))) [cos (.5
arctan
(y / x))
+ i sin (arctan (y / x))]

6) ln z = ln[sqrt(x^2 + y^2)] + i arctan (y / x)

7) e^z = e^x(cos y + i sin y)

8) sin z = sin x cosh y + i cos x sinh y = -i sinh iz = (e^iz - e^-iz) /
2i

9) cos z = cos x cosh y - i sin x sinh y = cosh iz = (e^iz + e^-iz) / 2

10) sinh z = - i sinh iz = (e^z - e^-z) / 2

11) cosh z = cos iz = (e^z + e^-z) / 2

12) sin^2(z) + cos^2(z) = 1

13) cosh^2(z) - sinh^2(z) = 1

14) tan z = (sin 2x + i sinh 2y) / (cos 2x + cosh 2y)

15) cot z = (sin 2x - i sinh 2y) / (cosh 2y - cos 2x)

16) nth root of z = [nth root of (x^2 + y^2)](cos (q / n) + i sin (q /
n))

17) Newton's Method z(n+1) = z(n) - [f(z(n)) / f '(z(n))]

18) Henon Attractor: (for z(n) = x(n) + iy(n)) , x(n+1) = ax(n) + y(n)
and
y(n+1)= bx(n)

19) Halley Map: z(n+1) = z(n) - L[(2f(z(n))f '(z(n))) / (2(f '(z(n)))^2
-
f' '(z(n))f(z(n)))]

20) Lorenz Attractor: dx / dt = a(y - x) dy / dt = x(r - z) - y dz / dt

                        Complex Equations Researched

Here are the equations that we have used during the past nine years to
generate well over 300,000 Mandelbrot and Julia sets. We have over 3
terabytes of fractal data! Feel free to continue to delve into them
using
whatever software (your own or canned) you have available. Because I
wrote
my own code in C language and a complex math library was not available,
I
had to resolve each of these equations into real, f(x), and imaginary,
f(y), parts. Many, many long (but fun) hours doing just the basic
algebra
were spent in order to bring you the majestic beauty of these incredible
forms.

                             Lissajous Figures

A 3-D Lissajous figure is created using three parametric equations, one
each for the x, y, and z coordinates. These equations are functions of
sin
and cos, so they are periodic, with the actual period depending on what
values you enter. The values you input in these functions are: a, b, and
exponents x, y, and z. The value of t, the parametric "time" parameter,
ranges from 0 to the number of spheres plotted minus one. Thanks to
Aaron
C. Caba for the info.

We used five different sets of equations. Here they are:

Set 1)

x = r * (sin(a*t) * (cos(b*t)^x))

y = r * (sin(a*t) * (sin(b*t)^y))

z = r * (cos(a*t)^z)



Set 2)

x = r * (sin(a*t) * (cos(b*t)^x))

y = r * (cos(a*t) * (cos(b*t)^y))

z = r * (sin(a*t)^z)



Set 3)

x = r * (sin(a*t) * (sin(b*t)^x))

y = r * (sin(a*t) * (cos(b*t)^y))

z = r * (sin(a*t)^z);



Set 4)

x = r/4 * (a * sin(2*(t-pi/13))^x)

y = r/4 * (-b * cos(t)^y)

z = r * (sin(a*t)^z)



Set 5)

x = r * (sin(a*t) * (cos(a*t)^x))

y = r * (sin(b*t) * (sin(b*t)^y))

z = r * (sin(t)^z)

                            Spherical Harmonics

Spherical harmonics are expressions in three-dimensional spherical
coordinates which are primarily used to describe the theoretical hybrid
electron orbital shapes in molecules. The three coordinates are r (for
radius), theta (degrees in the traditional x-y plane), and phi (degrees
in
the y-z plane). You may also recognize this way of laying out spatial
coordinates from Star Trek's "210 mark 45" designation for navigation as
the degrees in theta and phi. As with the rectangular coordinates, x, y,
and z, we can describe any point in three dimensional space using such a
coordinate system. All types of scientists use spherical and cylindrical
(rho, theta, and z) coordinate systems to analyze various physical
phenomena.

Here are a few of the examples we have used to produce our mathematical
"flying saucers:"

     r = (cos (theta))^2 + (cos(2 * theta))^4 + sin(4 * phi)

     r = (cos(12 * theta))^5 + (cos(8 * theta))^3 + cos(6 * theta)

     r = 2 * (cos(6 * theta))^6 - 4 * (cos(4 * theta))^4 - 2 * (cos(2
     * theta))^2

     rho = (sin(theta))^4 + (sin(2 * theta))^2 + e ^ (1 - sin(z))

     rho = 4 * (cos(4 * theta))^4 - 2 * (cos(2 * theta))^2 + (1 + cos
     (z))^2

You can experiment with an infinite number of possibilities. You will
soon
discover what each coefficient, exponent, and function does to the
overall
shape of the object. Happy Hunting!


                           Affine Transformations

(Due to the limitations of web publishing, our notation of matrices,
symbols, subscripts etc. will be clumsily laid out...please bear with
us...as our tools improve, so will our presentation.)

As given by Barnsley in "Fractals Everywhere," an affine transformation
is
a manipulation of a geometric set of points (here x1 and x2, or just x)
using matrices and column vectors such that:

                 w(x1,x2) = (ax1 + bx2 + e , cx1 + dx2 + f)

A general affine two-dimensional transformation, is given by:

                               w(x) = Ax + t

where A is a 2 x 2 real matrix and t is the column vector:

                                    A =
                                   (a b)
                                   (c d)

                                    t =
                                    (e)
                                    (f)

In graphic terms, the A matrix transforms x by a linear transformation,
which deforms space relative to the origin (involving rotation and
rescaling), whereas the t vector merely translates (moves) the points
once
the deformation is complete.

The matrix A can always be written as:

                                    A =
                            (r1 cos g -r2 cos h)
                            (r1 sin g r2 sin h)

where r1 and r2 are scaling factors and g and h are rotation angles.

Barnsley continues in his book to describe Iterated Function Systems, a
way
of describing objects created by affine transformations. Using the
letters
w, a, b, c, d, e, and f as defined above, he offers a typical a typical
fern designation in tidier "IFS code:"

        IFS code for a Fern (Barnsley)

  w   a     b     c     d     e   f     p
 1    0     0     0     .16   0   0     .01
 2    .85   .04   -.04  .85   0   1.6   .85
 3    .2    -.26  .23   .22   0   1.6   .07
 4    -.15  .28   .26   .24   0   .44   .07

Notice he provides a number p which corresponds to the probability that
each of the four "w" transformations will be used given each point
(x1,x2) that is to be manipulated. All of the p's must add up to one.
Because of this probability factor, each time you generate a fern, it
will be a slightly different fern. Thus we are not producing a
"deterministic fractal," as are Mandelbrot and Julia sets (which are
exactly reproducible), but more of a "random iteration" fractal.

Hey gurus, I need some help! I, once upon a time, created this PHC image:

with the following formula and par. Now when I go to generate it, I only get the
mandel curve part, not the lambdafn spiral. I need this to get this to work for
a deadline that is almost past. Can anyone duplicate my problem and/or suggest a
solution? (I need to generate at d&c high resolution image.)

Thanks for your help.

Bug in Fractint 19.6: the "reset=" in a parfile doesn't seem to kill a
viewwindow setting. If I go through a PAR and hit an image with odd
viewwindows, they stay that way after that image, instead of being reset
by the next par's"reset=" line.

Hrm?
Really huge numbers pop up taking the cosine of a complex number with a big
imaginary part. That magnitude under 1 appliesonly on the real line...

Hmm... this was something I wasn't aware of.  Guess I'll have to educate
myself about this.  In spite of having taken math through advanced calculus
(and four years of physics), I don't think I ever applied trig functions to
complex numbers.  Or maybe I just forgot.

I've had the same problem.  On those "square" fractals that don't take
up the entire screen.  After running one if I want to run a saved
image or another paramater I have to restart FRACTINT.  I have a, more
or less, generic video card (made by Phoenix, it's a TRIO 32/64) with
2 meg O' ram and I run FRACTINT at 1024x768x256.  I've tried other
resolutions and it made ono difference.  It's not a "MAJOR" problem
but it can be annoying.  Is there a setting I can add to the
"sstools.ini" file to fix this?

Please lemme know if you folx have any solution.

There are formulas for the sine and cosine of a complex number in terms of the
sine and cosine and hyperbolic sine and cosine of the real and imaginary
parts. The hyperbolic components can become unbounded for big imaginary
parts of z.

You could also use the Maclaurin series for sine and cosine.

Restart Fractint? I've never had to do that; manually turning view windows
off has always sufficed. Are you using version 19.6 or an earlier version?

I believe this feature was deliberately designed to permit viewing of a series
of fractals as thumbnails without having to redo the view setting for each
one.  I find this very useful when looking for an image whose name I can't
recall.  To reset the view to normal press <v> to enter the view menu then
press <F4> to reset the defaults.  Hope this helps.  Tom

Seems like there should be two different viewwindows then. A regular one
that is reset and one that works for thumbnails, which might instead be
invoked from the video modes, act like a video mode, and display say a
64x64 image at 1024x768...you choose the "real" video mode and the
resolution like view window.

Paul,

I'm using FRACTINT 19.60.  By restart I meant hitting the <delete> not
literally shutting down and re-launching.  If I don't the images all
come up as squares versus full screen.  I've got over 50 meg of
fractals on my D:\ drive (That's where FRACTINT is), only a small part
are squares but they do look dang neat (IMHO they'd look better as
full screen), still when I run 'em it would be nice to be able to go
with anothe image without the re-start.


Oh well, hope this was useful info.

While it does not directly address this (though it might if it was placed
in the pars), you can use fractint's fastrestore option, as described in
the list of new stuff for 19.6:

"Added command line option fastrestore=yes|no. Default is NO. When YES,
    causes viewwindows to be set to NO before each restore, so that
    otherwise normal gifs will not be drawn at the reduced aspect when
    viewwindows was previously set to YES; and bypasses the warning which
    is displayed when a restore is to be viewed in a video mode other than
    the one at which the gif was saved. Combined with askvideo=no, all
    restores will automatically be made at the user's default video mode.
    This feature will be helpful when cycling through a group of gifs in
    autokey mode."

You could put this in sstools.ini.

The F4 trick works for me to......my steps are

1.  hit v to bring up the view screen
2. hit F4 to reset to the defaults
3.  hit enter and the screen starts to re-draw the image to whatever I have
in my sstools.ini file

I've been trying to solve my disk-video-doesn't-work-in-batch-mode problem,
and I was just wondering if there was any way to override the default vid
mode for a restored image using view windows, or something.  The problem is,
I have a bunch of images I started in 1024x768 mode, and I want to resume
them in diskvideo mode so I can run them in the backround in win95.  I have
a batch file to do this, and which uses a dos for command to run through all
the images in the directory and finish them.  But fractint always uses the
graphics mode, not disk-video.  (I know I already asked this once, but I
thought maybe someone might have thought of something since.)

Thanks, Michael, it worked for me.  Oddly, though, askvideo behaves
differently in 19.3 and 19.6.  In 19.3, it does what one would like,
resets the viewwindow without complications, but in 19.6 an image
restored from gif is displayed in the current video mode (as opposed
to the mode it was saved in).  How Fractint performs this feat of magic
without regenerating the image I haven't a clue, but I'd rather it didn't.

For those having trouble with losing slices of images when returning
from option screens or editing the palette, textsafe=no should do the
trick.

According to Fractal Creations (2nd Ed.) by the honorable Tim Wegner and
his trust companion, Bert Tyler, "SIMPLGIF...reads your multi-image GIF
file and uses it to generate a simple, single-image GIF called
SIMPLGIF.GIF...Be aware that this process can be used to generate *huge*
images, and huge images come with corresponding appetites for disk
space...Note that this program needs to create a temporary uncompressed
version of your final image as an intermediate step. In this case, you
really do need 4GB of free disk space for a 64K x 64K image--in addition
to the space taken up by FRACTMIG.GIF and SIMPLGIF.GIF. As a practical
matter, most users of the "divide and conquer" feature should limit
images to a "modest" 4K x 4K or 8K x 8K resolution (which are actually
pretty high resolutions!).

Could you post a list of the controllpoints for the boundaries?

Considering that one pixel in 19 decimals accuracy at 32000 iterations
takes about 1 second on my maschine and that you can communicate at up
to 496000 BAUD over a normal Amiga Serial, thats 62000 Pixel a second
or roughly one 320x200 Picture in one second.

No matter how slow the serial ist, if the conected hardware is fast
enough and complex enough, its a speedup. Of cause its worthless if it
can't do at least n iterations with m dezimals accuracy by itself.

Maybe you just hit the M-Set. At 17-decimals and 2,000,000,000 a Point =

in the M-Set will take rather long.

Considering that 2**16 (65536) iterations take about 1 second on your
comp and you are trying to do 2**31 iterations, which will take 32768
seconds a point in the M-Set. 32768 s =3D 546 min =3D 9 hours.

After those 9 hours you should get ONE pixel further.
With 3 Pixels a day (well, lets round up) you would need 21333
days. Lets say half your image is in the M-Set, which gives 10666 days =

=3D 30 years.

I hope you see that you eigther have to decrease the itterations or
get a far bigger maschine. With 17 decimals theres no need for that
many itterations anyway.

When a gif is loaded back in xfractint only the lower 16 Bit of the
itteration is restored. When the Image had 65536 itterations set, it
will have 0 itterations after loading and then crash. Its awullfy
buggy.

Subject: (fractint) documentation
Date: 08 Mar 1998 11:12:03 -0800

I've been reading the documentation for fractint (!!!!!!!!!)
Goodness.....it's wonderful!!

I must say I still don't understand some of it....but it's much more
meaningful than when I started using Fractint a year ago....documentation
for a graphics program is about as hard a problem as there is, I think.
Thank you Stone Soup Group.

I noticed in my reading a new-ish standard formula....voltera_lotta or
something like that. Really neat!! First try outta the box yielded this image

wizvoltera_lotta   { ; wizzle 3/7/98 w. creams4.map
                     ; something different
  reset=1960 type=volterra-lotka
  center-mag=+1.04755944931163900/+1.38606010016694400/0.9661836/1/-90
  params=0.739/0.5 float=y colors=@creams4.map
  }

The color map is a really good one to re-do in other colors.  It is what I
think of as a "blacks" map.....yup....lots of black here and there.  It was
part of my "cream and gold" period....I'm now in my "grey" period. It
cycles nicely too....so do try that....there is an amber-ish point, even.

Speaking of amber....Pete

Did you get anything close to what you were visualizing for bugs in amber?

And how can one determine the radius of the bulbs? Witout that it
would mean nothing to now the tangent points.

May the Source be with you.

This applies to restores from GIF, in both cases.  Of course, askvideo
has no effect (good or bad) on restores from PAR.

I think I meant "loading a new palette", which is just another option

Subject: (fractint) How to use simplgif (long)
Date: 08 Mar 1998 13:18:47 -0600

Wizzle asked:

> 1. what is simplegif's purpose?

The main purpose of simplgif is to convert a multiple image GIF file
to a single image GIF. A multiple image GIF is a single file, but
within that file are separate images. The reason you might want to
do this is if you wanted to make a super resolution image.

Suppose you have just created the world's most dazzling fractal, and
you want to create a wall-sized version of it for your exhibition at
the Metropolitan Museum.

You might do the following steps. (In real life you can use a higher
resolution - this is just a low resolution example for you to
follow).

a. Generate a relatively low resolution version of your fractal, say
320x200 (F3)

b. press <b> to take you to the screen that generates PAR files (The
"Save Current Parameters" screen.

For safety, enter the name of a brand new PAR file. At the bottom,
enter integral values for "X Multiples" and "Y Multiples". If you
used 2 and 2, this would result in a final image of 640x400.

After you press <enter>, exit Fractint, and in addition to a PAR file
you will see the file makemig.bat in the current directory. The
contents of this file is:

Fractint batch=yes overwrite=yes @fractint.par/test_00
If Errorlevel 2 goto oops
Fractint batch=yes overwrite=yes @fractint.par/test_01
If Errorlevel 2 goto oops
Fractint batch=yes overwrite=yes @fractint.par/test_10
If Errorlevel 2 goto oops
Fractint batch=yes overwrite=yes @fractint.par/test_11
If Errorlevel 2 goto oops
Fractint makemig=2/2
Rem Simplgif fractmig.gif simplgif.gif  in case you need it
:oops

The first lines of this batch file generate four 320x200 images that
each contain 1/4 of your total image.

The line

Fractint makemig=2/2

combines these images into a  multiple-image GIF file called
fractmig.gif. Unfortunately most service bureaus who print images
have never heard of a multiple image GIF. (You can view it in
Fractint though - you will see the images added the the total
image one piece at a time - try it.) This is where simplgif comes
in. The last line of the batch file, which is commented out, invokes
simplgif. If you uncommented it, it would look like:

Simplgif fractmig.gif simplgif.gif

This simply converts the multiple image GIF file fractmig.gif (the
file with fractint creates using that name) to a single image GIF
called simplgif.gif (or any other name you used as the second
parameter).

This example is silly because it only results in a 640x400 image. The
real excitement happens when you use a video mode of
something like 1600x1200 and, say, multiples of 4x4. This would
result in a final image of 6400x4800, which is a seriously high
resolution. You might want to go higher.

The earlier simplgif released with version 19.6 had various problems
with some images. The new simplgif is rock solid and capable of up to
32000x32000 pixels IF you have enough disk space for the temporary
file. For that huge size the temporary file would be about a
gigabyte, which is no longer out of the question with today's disk
drives. A more practical limitation is the maximum image size a
service bureau who prints your image can take. Up to 16K pixels isn't
too hard to find, and an image that big looks good blown up to wall
sized. Jon Noring and others have made images for exhibitions that
big. Maybe Lee Skinner can tell us his experience.

I hope this helps. Try the simplfied example, then when you have lots
of free disk space and time. try a larger resolution.

Yeah, it does help if one reads the manuals. I haven't read all of the
fractal stuff. Especially about writing your own formula files. Hehehe. I
don't know how to program. But I assume it's fairly difficult. I'm a chemist
mind you. Computer related subjects are just my hobby as well as graphics.

Speaking of which, I might be getting a newer, faster computer soon. I'm
still running at P100Mhz, 2.1G, 64MB RAM. What is everyone else running at?
I've gotta admit, my computer does run smoother than some new ones. It
doesn't crash as often and doesn't freeze as often either. I brought the
Fractint program to work and loaded it onto a p233 or higher and those
perform slightly better than the one I have now. I thought they would
perform astoundingly. Is that due to the program or the computer?

I'm pretty sure that someone has asked this before, but I'll try
anyways.

Will Fractint compile with DJGPP? I want to try my hand at adding PNG
support, but Fractint is a real mode program and DJGPP makes 32 bit
protected mode exe's. The C part would probably compile OK, but I don't
know about the assembler. It would be nice to know before going through
the trouble of downloading, unpacking, and rewriting the makefiles.

Tim,

I have a bunch of new Fractint images I want to generate at 1600 x 1200 and
then reduce to 640 x 480 (for anti-aliasing) for my web page. So if I make
a mulipart GIF with simplegif will I then be able to load that into Picture
Publisher whence I can reduce their size?

Also, if this can be done, I am wondering how long this tends to take to do
per image (say, on a Pentium/166). If they do not take too long, I wld be
interested in checking whether either the DJGPP-compiled or the
MSVC++-compiled executable is faster.

Peter,

 - I have a bunch of new Fractint images I want to generate at 1600 x 1200 and
 - then reduce to 640 x 480 (for anti-aliasing) for my web page.

You don't need SIMPLGIF for that.  I do this sort of thing all the time
(although I don't use Picture Publisher to resize).

 - So if I make a mulipart GIF with simplegif will I then be able to load that
 - into Picture Publisher whence I can reduce their size?

SIMPLGIF doesn't make multi-part GIFs, it takes multi-part GIFs built with
FractInt's divide & conquer process and creates a *simple* GIF, one that
any program with GIF support will read.  I have used this process before,
and most programs do not support the multi-part GIF properly.  SIMPLGIF is
essential.

 - Also, if this can be done, I am wondering how long this tends to take to do
 - per image (say, on a Pentium/166).

It depends very much on the image.  I have images which render at 1600x1200
in a matter of minutes on my P166; I have others which take hours.

Hi Pete,

The problem is that

"Floating-point flag is activated"

and it should be arbitrary at this point. Even zooming in more
does not activate it though.

I went to the MSet (hit space bar) and tried another Julia.
It did switch to arbitrary precision after zooming to about
the depth of yours.

development lists they are bragging about 10 cycle iteration times. So wi=

a P100 that would be 10,000,000 iterations/sec or 200 sec per point at=20
2,000,000,000 iterations using floating point.  If you failed to back off

you might still be in arbitrary precision math.=20

Has anyone benchmarked iterations per second for arbitrary precision math

If you are using period detection, the limit of 2,000,000,000 would occur
very rarely. The amount of time spent above what looks good and what
hits the limit is normally small.

Yep, looks like we got a major problem here.  Even on Linux and
XFractint.  Something's definitely the wrong precision.

Regarding the arbitrary precision, it doesn't make the switch until a
"mag" on the order of 10^21, where it suddenly jumps to 26 decimals!!!
Then the strange thing is that when you zoom back out, it stays at
arbitrary until you get down to below 17 decimals, the pops back into
floating point.

There is good news, however.  There is a way to control where the
switchovers occur between floating-point and arbitrary precision.
Unfortunately, I couldn't find it in the XFractint help files.  Perhaps
someone else would like to help out???

I think 2**16 iterations per second is a good guess for arbitrary
precision with 17 digits, which would make it 9 hours a pixel and
about 3 pixels a day at 2**31 iterations.

Murphys Law: It will occur!

And then you have to wait 9 hours.

How good is the period detection with 17 decimals precision? Points on =

the edge of the M-Set will converge slowly to the fix points and they
will most likely have a high period. Say you have a period of 50, then =

the period seen by the periodicy check could be >1000 because of
rounding errors. Also it could take millions of iterations until the
periodicy becomes clear.

Remember, some points converge real slowly towards their periodic
points and that will be the points you are zooming into, because there =

lie the intresting parts.


What would realy help here, would be SOI (Simultanious Orbital
Itteration). It does a bunch of iterations for 9 control points of a
rectangle and then divides it into 4 smaler rectangles doing another
bunch of iterations. The speedup of this method is poor for the
complete M-Set and the first zooms, but the deep one goes, the better
it gets. Its speedup grows with zoom and not decreases like the
methods fractint knows currently.

May the Source be with you.

I tried several times to see the par posted with this formula but got an

No problem!  This is always the case with computer stuff -- the vast

teaching the basics anyway.

Also, your questions may provide a good basis for a

Hi Wiz,

I also noticed that when switching to viewwindows, it gives an error 4

Does anyone know if this is a bug of some sort?

Jay,

Those times are for double precision, not arbitrary precision.  Apples and

Yeah, it does help if one reads the manuals. I haven't read all of the
fractal stuff. Especially about writing your own formula files. Hehehe. I
don't know how to program. But I assume it's fairly difficult. I'm a
chemist
mind you. Computer related subjects are just my hobby as well as graphics.

Speaking of which, I might be getting a newer, faster computer soon. I'm
still running at P100Mhz, 2.1G, 64MB RAM. What is everyone else running at?
I've gotta admit, my computer does run smoother than some new ones. It
doesn't crash as often and doesn't freeze as often either. I brought the
Fractint program to work and loaded it onto a p233 or higher and those
perform slightly better than the one I have now. I thought they would
perform astoundingly. Is that due to the program or the computer?

Subject: (fractint) symmetry
Date: 09 Mar 1998 11:54:12 -0800

I have a basic question.  Looking at the formula for
the Mandelbrot set,  I don't see why it has x-symmetry
but not y-symmetry.   It must mean that if you substitute
the negative of the imaginary portion of c for the positive you
get the same thing,  but if you substitute the negative of the real
portion you get something different.  Is my understanding of this right?

Does it have something to do with the behavior of complex numbers?
I thought i basically acts like a constant in these equations.

Subject: Re: (fractint) symmetry

For the Mandelbrot set, the first few iterations go like this:

x0 = 0
y0 = 0

x1 = cx
y1 = cy

x2 = cx*cx - cy*cy + cx
y2 = 2*cx*cy + cy = cy * (2*cx + 1)

In this last step, it becomes clear why there's xaxis symmetry.  If you
replace cy with -cy above, it won't change the definition of x, since cy
is squared (-cy*-cy = cy*cy).  In the expression for y, changing cy to -cy
will simply negate the entire expression.  In general,

xnew = xold*xold - yold*yold + cx
ynew = 2*xold*yold + cy

So again, if cy (and thus, yold) are negated, the only change will be in
the sign of ynew.  Since the set definition only cares about the magnitude
of the iterate (sqrt(x*x+y*y)), y and -y have the same effect.  This
explains the xaxis symmetery.

However, changing cx to -cx will give you problems right away, since only
some of the terms will change sign, but not all of them.  For example, if
cx=1 and cy=0.5, then in the second iteration, you would have:

x = cx*cx - cy*cy + cx = 1*1 - .5*.5 + 1 = 1.75;

negating cx to -1, we have:

x = -1*-1 -.5*.5 -1 = -0.25.

The magnitude of the real part of the iterate is changed, not just its
sign.  That's why the Mandelbrot set does not have y-symmetry.

For the Julia set, the first few iterations go like this:

x0 = pixelx
y0 = pixely

x1 = pixelx*pixelx - pixely*pixely + cx
y1 = 2*pixelx*pixely + cy

Now, since we're in the pixel plane, instead of the c plane, we look at
changing the signs of pixelx and pixely.  Since cx and cy are fixed, and
the pixel part of x1 won't change (both pixelx and pixely are squared), x1
won't change by switching the signs of pixelx and pixely.  If we change
either pixelx *or* pixely, then we'll botch up y1, since cy won't change.
However, we can change *both* pixelx and pixely, since their negatives
will multiply into a positive.  The net result is no change, which means
that we can treat the point (pixelx,pixely) the same as the point
(-pixelx,-pixely).  Thus, Julia sets are symmetric about the origin.

Similar analyses with other formulas of the type z^n + c will show how
their symmetries develop.

The most important thing, I think, about these is that (-1)^2=1 and
(1)^2=1, but (i)^2=-1 and (-i)^2=-1.  Squaring i and -i take you to
-1, not to i or -i, so the operation is not "symmetric" in this sense.
Also, consider the following examples from the mandelbrot set:

z[0]=0,
z[n]=z[n-1]^2+c

c=-1

z[0]=0
z[1]=-1
z[2]=0
z[3]=-1
...

This series will go on forever and z[n] will never diverge, thus -1 is
on the interior of the set.

c=1

z[0]=0
z[1]=1
z[2]=2
z[3]=5
z[4]=26
...

This series does diverge, and most programs would detech this as soon
as the magnitude reaches 2 (z[2] above).

This slice of the Mandelbrot set through the real axis is
mathematically interesting, even though it is not necessarily visually
interesting.  If folks out there have access to gnuplot, try the
following:

gnuplot> f(x,n)=(n==0)?0:f(x,(n-1))**2+x
gnuplot> plot [-3:3] [-3:3] f(x,1)
gnuplot> plot [-3:3] [-3:3] f(x,2)

as you let the "n" parameter get larger and larger, the plot becomes
more kinked up and chaotic.  There are stretches from -.75 to .25,
from -1.25 to -.75 and so on that are relatively smooth, even at
higher iteration limits.  These are slices through the various bulbs.
The rightmost one is the main cardioid, to its left is the large
period 2 bulb, to the left of this is the (period 4?) bulb, and so on.

Even though these are smooth, since they have different periods, the
graph never settles down to one shape.  If you are patient, try
ploting the graph for 100,101,102 and 103 iterations on the same set
of axes.  You should be able to see that in the main cardioid, there
is only one graph, which splits into two graphs when you enter the
period two bulb and then into four when you enter the next bulb.

    I've run into this problem a few times myself while exploring the
mandelbrot at the edge of arbitrary prec. Sometimes Fractint doesn't switch
over when it should. The resulting image is definitely suffering from lack
of precision. I've also seen the converse happen and arb. prec. kicks in
before I think it should. The best trick I've found is to make sure that
you save the previous image, (the one you last zoomed from). If you
run into a problem, you can restore it and try zooming again with
a slightly different zoom factor or move the zoombox to a slightly
different position. It may not exactly be a bug, but I think the
code should be made a little more consistent in determining when
it switches modes.

There must be a way to manipulate the arb-prec switch without using

the number of digits to use, or let you use its recommendation.  New version

You have to use debug=3200 to force arbitrary precision.  Then, of
course, you pretty much turn your computer into a 4.77MHZ 8088!  :-)  I
tested it with bfdigits=100, which is way too many.  20 digits is
enough.  Given enough time, you'll be able to see that your Julia is not
so special but still real interesting.

    Well if you choose the number of digits, we wouldn't be able
to call it arbitrary precision anymore would we. :-) Seriously though,
this is a feature that I think would be interesting. I've always
wanted to compare images calculated with different degrees of precision.

I got the same problem and resolved in the same way. In the email I just
received, Brian's msg also wrapped giving in  one part the following:

b4=abs(conj(conj(pixel^2)))*conj(flip(pixel^3))-conj(0.1/pixel-flip(0.01/pix
el))

When seeing the error msg with a ^ pointing to a spot saying "Needs a...",
check the lines in the formula.  If something of the above is seen where
there are not the same number of parenthesis opening and closing on the
same line, straighten it out by going to the appropriate area and backing
up the line. In the above, note that there 3 "openings at the beginning of
the line and 3 closings:
"b4=abs(conj(conj(pixel^2)))"
Later in the line there are 2 openings, but no closings:

(0.1/pixel-flip(0.01/pix

and on the next line there are no openings but two closings:

el))

Fractint is gojng to go into a shock because it will not understand the above.
By backing the "el))" to fit onto the end of "(0.1/pixel-flip(0.01/pix"
you will then have: "(0.1/pixel-flip(0.01/pixel)) and voila! A word: pixel,
and more importantly, 3 open parenthesis and 3 closings. Everythin works
now...

However, with my post, and then a query concerning Angela's creams4 map, I

it contained a lot of space and cream/gold colors. Looked good...then:
Tried that map on one of "O" 's icon images d/l'd from abpf. Try it, you'll

_That_ is a good map.

Hi Kragen
        Thanks for your kind response.  And I'll put a question to you right
away. (There are so many to ask - but number one...)
        What is SSTOOLS.INI file?  I've looked high and low for it, but can
not find such a thing.  I've looked in the Fractint listing (file-?) and it
is not there.  And, even if it were, when I have tried to enter one of the
listings, as, for instance, an indicated map (i.e. 'Alien Map)- I get a
drop-down box saying, in effect, "Can't open.  Use program that you got it
from" or, some such wording.  So then what?  Is there a place in the
Fractint program that I can push a button and, lo and behold, there is the
SSTOOLS.INI.?
        More buttons than I care to imagine.  But it is great when those
colorful designs generate - like a monstrous ship appearing out of a heavy fog.
        Thanks again.  Hope this will clear up mystery #1.
                                Ray

                You did good things making that color-map developing
tutorial.  But when I try to download it, the only things that print are
the images and colormaps.  They are beautiful and represantative of what you
are saying but without the text I can't benefit and learn from them.  My
brain is too far gone to be able to read that much material and retain it
for more than 27 seconds.
        Am I presuming for trying to download that material at all?  I
certainly do not want to offend anyone, or break protocol, or violate any
rights.  Perhaps I need instruction in that department before I presume to
resume.
        Since I am just about at a stage in Fractinting when different
colormaps would most certainly help I am interested in creating some.  The
"Fractint Commands" instructions are helpful but to the uninitiated fairly
obscure.  Your instructions would be most helpful.  I truly need someone to
tell me "Push this button - then that one...." etc. when it comes to grey
areas.
        Thanks for listening (or reading).
                                        Gratefully

A note to formula writers, if you have a very long line, you
can spill to a new line by appending "\" to the end.  I just tried it.

It will look like this...

b4=abs(conj(conj(pixel^2)))*conj(flip(pixel^3))-conj(0.1/pixel-\
flip(0.01/pixel))

The issue here is the view in Fractint. The formula window is only
so wide.   (You can scroll the formula window left/right/up/down
with the Control/Arror keys.)

Yes, I know, that is why I asked for timings on the arbitrary percision
math.

I have been looking at Keith Briggs double-double (30 digit) package
for C++ and found about 40,000 iterations per second on a P200.  That
is not assembler and not unrolled loops. So Fractint should be able to get
what ... 160,000 iterations/second?

Bottom line...

It looks like 2,000,000,000 iterations is too many on this year's machines.
:-(
Try 100,000 or so.

Thanks for the pars and the sstools.ini fix. I'm presuming I can add the line

 recordcolors=yes

pretty much any where in sstools.ini? For some obscure reason......just
every now and then......(without human intervention, of course).....my pars
don't save the colors. Very strange. Actually, why would we want to save
the pars without the colors? Strange feature.

I tried the esher julia formula too and didn't get anything much right off.
Volterra_whatever was Very responsive ....like our friendly gravijuli series.

Angela

p.s.  I know the creams4.map doesn't look too creamy at this point....it's
been thru a bunch of iterations because the colors and black areas seem to
be placed well for many fractals.

Ray...

sstools.ini "ships" with fractint under the disguise of

sstools2.ini

What you need to do is read up a bit on the features sstools.ini controls
at the Fractint homepage....

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

or pay attention to postings on the list......or get Jay Hill to tell you
where his great explanation of sstools.ini is posted (I remember it being
somewhere).

Then...decide how you want to modify sstools2.ini (you can do that in
notepad) and save the file as sstools.ini in your Fractint directory.

Here is my sstools.ini file

[fractint]
; note: replace (for example) "c:\fract\map\tworain.map" with
; the correct path on your drive so fractint can find the files from anywhere.
map=c:\fractint\gen-2.map
parmfile=c:\fractint\pars\mar98.par
recordcolors=yes
formulafile=c:\fractint\mar98.frm
lfile=c:\fractint\fractint.l

autokeyname=c:\fractint\key
;filename=c:\fractint
savename=c:\fractint\83avw001

WinfractPosition=-5, -5
ImageWidth=1024
ImageHeight=768
ZoomOut=False
WindowSizing=False
CoordinateBoxOpen=False
ZoomBoxOpen=False
CoordBoxPosition=712, 49

The features I found most useful were:

1. a new default colormap (I use one I made myself called gen-2.map and
which is available in my wizmaps.zip kit at
http://wizzle.simplenet.com/fractals/wizmaps/wizmaps.htm)
2.  more descriptive filenames for saving gifs. I use a naming convention
that I change each month so I can tell one "batch" from another
3. defaulting to the current months pars and formulas (which i call
mar98.par and mar98.frm for example) - I re-set this every month but it
helps me keep up with the list
4. selecting a default video setting (I like sf6)

There are oodles of other features available as I've been learning here on
the list....just haven't had the time or need to incorporate them all.

Many web pages are pretty difficult to print because we web authors like to
have dark backgrounds with light print......I'm afraid I'm a prime culprit.
 However, downloading instructions in a form that will print well is easy.....

1. with the page you want to print open in your browser....select
"file....save as" which will download the page with the html code to your
own computer....stick it in a folder someplace where you can find it
2. open the page you just downloaded in your browser using
"file.....open".....the page should come up against a nice clean white
background which will print the text just fine right from your browser.

Hope that helps

That's still damn weird. So what happens if you try to turn off the

(What is the message then?) Hang or crash or bombs to DOS? Tried reinstalling

AFAIK the only way to restore an image in a different video mode is
manually using the video screen after the 'r' and filename choice. IMHO
Fractint 20 needs 2 key features for what you want to do:

1. A disk video matching each and every real video mode, even 320x200x4
   (ugh!);
2. An option that can be set before a restore, meant for batch use:
   fractint ... -novideo=yes ... [restore an image] ... batch=yes
   -savename=foo.gif -savetime=20 ...
   Here the use of -novideo=yes forces all restores to load into a disk
   video mode with colors and resolution matching the parameters of the saved
   image (whether the image was saved from a disk video or normalvideo mode
   with those parameters).

Hi Team Fractals:

Here's how I print out from Web sites. Before doing any printing job,
click on Print Preview to see how the pages will look when they are sent
to your printer. If it looks fine, then go ahead with the printing job.
If not, here's where I differ from Wizzle's suggestion. When clicking on
"save as" don't save as an html page. Rather, save it as (filename).txt.
This method will eliminate all html control codes from your saved file.
You'll be able to read your file easily without getting eyestrain from
trying to read the text among all those control codes.

Happy printing!

Well that won't have the pictures and if the web page has frames....

As for earlier remarks about sstools.ini, I did not find much in my
logs. A lot of talk about textsafe and some about how to set up timings.
Otherwise, most seem to have their own preferences.  A good look at
the docs can help one with what they prefer. An example is someone
recommended the quiting without asking setting. Well one too many
ESCs and you are out with that setting. Not  me, too likely to loose a
good image that way.

That's the painterly effect. It happens in Julia sets when orbits start
far apart, get close together and then diverge. In this case orbits of
nearby points started far enough apart (though barely, at e+11
magnification) for non-arbitrary to distinguish them. But they converged
so closely that roundoff errors changed caused rotated square groups of
neighboring orbits to lose their distinctiveness before they later spread
apart again. If you force arbitrary precision the errors will go away.
(Tim? How the heck was that done again?) This also occurs near the
int/float boundary when using ints, for some Julias. (Especially ones, like
yours, that come from in or near minibrots.) In that case the solution is
just to use float=y.

Date: 10 Mar 1998 01:14:05 -0500 (EST)


The Julia sets of z^n+c have n-fold symmetry. The reason why: The points
are the initial z values. If you have n initial z values equally spaced
about the origin they have the same nth power, by DeMoivre's theorem. (z^n
is r^n * cis (n*theta) where r is the modulus of z and theta the argument.
So the angle from the positive x axis is multiplied by n, the distance
raised to the nth power. Use units of 2*pi/n and consider that n equally
spaced points have angles, in those units, of k+r, with k an integer from
0 to n - 1 depending on the point and r the same for all points. Their nth
powers have the same distance (since the original points did) and the
angles are k*n+r*n. k*n, however, is k*2*pi in radians, and this is just
full turns around the circle and cancel out. That leaves them all at the
same distance and the same angle of r*2*pi radians.)

So these points have the same z^n,and thus the same z^n+c. So they jump to
the same second itrate, and their orbits are the same (and thus also their
fates) thereafter.

For the M-sets the symmetry is trickier. The c value is now the image
coordinate and the z value is initially 0. The iterates look like
((c^n+c)^n+c)^n+c...
Notice though that c^n+c is the second iterate and can be rewritten as
c(c^n-1 + 1). Thus n-1 equally spaced points have the same c^n-1+1.
Multiply that by c and we find the n-1 points don't converge to one, but
they do have equal moduli and n-1 fold symmetry in their angles again.
And so do their successors and so on, because the next iterations raised to
the n-1th power still have the symmetry, and lead to the same (c^n+c)^n-1
+ 1; and this multiplied by the original symmetrical c values leads to
further iterations with the same symmetry and so on.
So they must escape a circular bailout radius at the same time. Also they
must either be in or out of the set all together, not some in, some not,
because of that.

The bilateral symmetry of M-sets is tricky too, but explainable again.
Take two conjugate numbers z and w, of opposite imaginary part and equal
real part. In polar notation these are radius r, and angle +/- theta.
(Negating theta negates the sine but not cosine and so negates the
imaginary part, so conjugates have same real negated imaginaries, and
same modulus but negated angle.)

Take the nth power of these. Samemoduli means same modulifor the nth
power. Also means the angles have multiplied by n. One angle was say t,
the other -t, now they are n*t and -n*t, so again they are conjugates.
Thus two conjugate c have the same c^n-1. Add 1 and they are still
conujugate because 1 is real. Multiply by the original c, and they are
still conjugate. (Check the math: a+ib * c+id = ac - bd +i(ad + bc). a-ib
* c-id = ac - bd - i(ad + bc) so the product of conjugates is the
conjugate of the product.) So again they share the same fate because they
must escape at the same time, or never. Hence the bilateral symmetry.

The bilateral symmetry in Julias of z^n+c with c real arise the same way:
conjugate z's have conjugate z^n's and when c is real, conjugate z^n+c.
When c is not real, this is not true any more and we get the rotational
symmetry alone.

More complex formulas for M-sets tend to have no rotational symmetry
because there's no factoring like above, but bilateral if all coefficients
are real for same reasons. (Add real - conjugates stay conjugate; multiply
conjugates - conjugate products). Similarly more complex Julia formulas
usually have no symmetry, exceptoften bilateral symmetry if they happen to be
given real parameters and the coefficients in the formula are real.

Yes it works fine now.  I tried the "V" and "F4" things the other
night and nothing happened (Could be Win95 or just own stupidity,
maybe both) now it does work.  I did do an overwrite from a tape
backup from about 2 weeks ago too maybe that did it.  Oh well it's
hard to type with my foot in my mouth so I'll stop now.

                    Thanks for the suggestions anyway.


P.S. : A non - FRACTINT question here.  Will Red Hat Linux 5.0x run in
EDO memory and can/does it support Iomega external tape drives namely
the ditto 2GB?  I'm dying to try it out (see if I can teach myself to
use it from the ground up, literally from scratch) but if it won't run
in the system I've got there's no need in getting it.  Electronics
Boutique has it for $29. Just thought I'd ask.  I have a Western
Digital Caviar 4.0 ATA HDD too.  Basically what do I need to know
first is what I'm asking.  I know this sounds stupid but there are no
Linux/Unix people to ask around here.  Please let me know ASAP.

I agree with this. In fact, some of the questions asked on this mailing
list could have been answered by consulting the documentation. I'd like to
suggest that in future if people have a question on this subject they
should consult the documentation and tutorials first, and only come here if
they're no help or hard to understand. This list would still of course be a
good place for going into more depth than can sensibly be managed in the
docs (resulting in more stuff for the iFAQ!).

I don't want to sound like I'm policing anything here, but I'm sure that it
would be a lot more convenient to questioners to find the answers they're
looking for already sitting on their hard drive.

It's quite possibly due to the computer. Many companies (and not just the
knock-off clones) that advertise machines with superluminal processors
don't mention that the motherboard might be nowhere near as fast - with the
result that the processor spends a lot of its time twiddling its contacts
waiting for the rest of the computer to catch up. A friend of my brother's
has a Hewlett Packard P233 and it _crawls_ in comparison to mine; which (to
partly answer your question) is a P166 with 2.1GB/32MB. The motherboard can
generally keep up (Windows permitting).

You have to run Fractint with the option debug=3200.

BUT BUT BUT  Even with it forced, it still didn't use enough digits due
to the effect you mentioned.  To get this particular one to work, you
have to force the number of digits to about 20 using the "developer"
option bfdigits=20.

Whoa, nelly! An MMX chip most certainly does not speed up Fractint versus
a non-MMX chip that is otherwise equivalent (although it's vaguely
possible that the cache memory differences between MMX and non-MMX
systems might matter a trifle) nor will it, until we recompile fractint
in a 32-bit win95 compiler on an MMX machine... and possibly not even
then... and while only the gods and Andy Grove know exactly what the
definition of "MMX" is, the PentiumII is basically an MMX chip anyhow.

I would tend to agree with somebody-or-other that a lack of speedups on
high-end chips is more a sign of cheesy system components than anything
else. The gain in floating-point speed between a P166 and a PII-300 is
more marginal than the megahertz-numbers would suggest, but there is a
gain... someone's going to post with clock timings and make me feel silly
for making such a vague, unfounded statement...

I noticed the same thing on Saturday, when I generated one of
my old reliable biased 'brots, something I hadn't previously done in
Fractint.  When I didn't get the image I expected, I started making
guesses at systematic causes, and got it on the second try
(fortunately it was a real-only offset, which made things easier).

First, let me say :o) we're among friends here, I'm not flaming.

Of course you're both right.  The documentation is good,
especially for a large, complex program written by a committee
of dozens who were never paid, but were also never imprisoned
for a ten hour corporate meeting to hash out the details.  But it's
not perfect.  The path through "Help" is not always clear.  For my
part, in future I shall endeavor to make a note of these difficulties
and provide feedback to the authors.  We can *all* help to improve
Fractint by documenting problems (real or perceived) with the
program and documentation.

For the present, please forgive those of us with weak taxonomic
skills ;o)

I am using a ZIP external parallel, for which my kernel came precompiled,
even.  It works fine.On the RedHat List I have seen several people ask
about DITTO, and tape-backup is a staple of the *nix diet, so I bet they
are supported.  Check one of the many "supported-hardware lists" for

I'm in the process of doing the same.  There are *very* few systems that
can't be improved by running Linux...

Subject: (fractint) Browser
Date: 10 Mar 1998 11:39:56 -0700

 To whomever can help.
                Is "Netscape" a browser?  When I am wandering around looking
for a particular web-site, or home-page, am I browsing?  Or is a "BROWSER" a
different program that must be added to a computer - in other words, a
software option?  Or is it contained in the computer somewhere or somewhere
in Netscape?

Many thanks to those who have helped my previous problems - Wizzle,
Gumbycat, Bob Carr, Kragen, Bob Margolis, Jay Hill and davides.  I am
struggling to master all the advice that was given.  Whether mastered or
not, I am nonetheless deeply appreciative.

The Nerve of this guy!
        Even though I am new to the group I must take issue with those who
say that docs should be read before time is wasted with needless questions
to the list-server group.
        I have down-loaded perhaps 3/4" of material from Noel Giffens
Fractint Home page, have faltered through through most of it, admired the
plethora of really outstanding images in those pages, have infinite respect
for the Stone Soup Group who created Fractint and for all others who have
contributed - BUT - surely you can understand that almost all who are
mightily informed about a subject, and are writing user-manuals and
documentations of just about any sort, do an awful lot of presuming.
PRESUMING!  This group presumes you know this, and that group presumes you
know that, and another group presumes you know at least this much about
something else.
        I've read user manuals of one sort or another, as we all have, I'm
sure, and almost all have been written by experts in their field who presume
you know this, that or the other.  They know it so well, and have known it
for so long that they feel sure you must know "at least this much".  Well, I
could go on and persue this much further, but I anticipate some negative
reponses and I don't mean to.  When I was 'teaching' my grand-children 'all
about' the computer, it was a very short time, indeed, before they were
teaching me.  The increase in computer knowlege due to interaction amongst
kids is practically an exponential growth.  I got left behind is all.
        No I am not whining, nor complaining, nor feeling sorry for myself.
I'm having the greatest time of my life with my new hobby.  I want to learn
and I want to learn more and more but, I can't run over to Jimmy's house and
spend hours with the other computer-kids picking up information.
        I don't feel that any of the criticism was directed at me, I am
merely expressing an observation.  Do you know that on the spec sheet of the
"USER'S MANUAL" for my computer it does not tell you what the MHz of the
computer is?  How's that for documentation?

        Thanks for listening.

Also keep in mind that FractInt directly accesses video memory, which on

from video memory, it will run better on newer processors.  This difference
is most noticeable on fast images.

Date: 10 Mar 1998 13:08:53 -0600

Ray,

 - Is "Netscape" a browser?

Yes.  A "web browser" (or just "browser") is a piece of software that lets
you look at web sites.  Some people get Microsoft Internet Explorer
pre-installed on their computers when they buy them; other people download
their browser from the Internet and install it.

 - When I am wandering around looking for a particular web-site, or home-page,
 - am I browsing?

Yes, that's browsing.  It's also called surfing, cruising, or whatever
euphemistic word suits your fancy. :)

 - Or is a "BROWSER" a different program that must be added to a computer -
 - in other words, a software option?

It is always software that must be installed on your computer before you
can use it.  But, you can choose which browser you want to use.  If you
don't like the one you have, you can download and install a different one.

 - Even though I am new to the group I must take issue with those who
 - say that docs should be read before time is wasted with needless
 - questions to the list-server group.

To a point, I agree with you.  There is a lot of information in the
FractInt documentation, and just because something is there doesn't mean
it's easily found.  As the documentation gets larger ("better") this
problem increases.  It'd be nice to see a search feature in the help, but I
don't have time to tinker with the code myself. :)

Sometimes it is frustrating to see the same questions asked over and over
again, but it is the nature of mailing lists and discussion groups in
general, whenever there is the possibility of new people joining the
discussion as time goes by.  A lot of discussions keep a FAQ for just this
reason.  FractInt is a big, complex program; I used it for a number of
years, chafing at the 2048x2048 limit, before I "discovered" the divide and
conquer feature that had been there all along.  And yet, it was in the manual!

My point: we all need to be a bit more tolerant.  Yes, it is nice for
people to check the manual and available documentation first to see if
their question is answered.  But we shouldn't scold someone because they
couldn't find the answer they were looking for, even if *we* know where the
answer is.

does fractint know when to kick it in?  Is there a certain "tolerance" or
something that it uses?  Oh, and how many digits does fractint have access
to in float-mode, and does it always use them all?

Hi folks,
I am reading poor solutions to a problem caused by web page
design problems. Someone posted a URL of a site discussing
good web page design, things like no blinking text, no scrolling
text, black text on dark blue background....

If you want folk to read and study your page, make it EASY for
them. Forget the cutsy artsy stuff if it is for study and reference.

I have access to a laser printer which will show shades of gray
for colors. Even it has trouble with some pages. I have a ink jet
also which refuses to print a color page unless I switch to the color
cartridge. I pain for the one line someone puts in color.

I copy as txt and the formatting is totally gone. I see one giant
run-on paragraph. My solution? Save as HTML and read in with
a browser with edit capability which lets me set the colors
and background.  It is a lot of trouble and does not easily deal
with the illustrations. Then there are the frame pages...
I usually move on to another site. There are so many others
that are not frustrating.

Bottom line. Keep It Simple on your study and reference sites.

Jay
PS. An example of what I recommend is my iFAQ
http://home.san.rr.com/jayrhill/iFAQ/iFAQ.html
where you will see it is bare minimum and links to
ASCII txt files which you can view, study, print save as
you wish.

  Now this is very interesting.  I have an IBM 6x86 P-150+ and have
been considering upgrading.  I would be very interesting in ensuring
that my upgrade would significantly speed up Fractint's rendering.

  So if I understand you correctly, this would be a good reason to
consider an AMD 233 MHz K6 (which has MMX) over a PII 233 MHz?

  I run Fractint 19.6 in a virtual DOS machine under OS/2 Warp 4.0.  It runs
very, very well there.  Normally, when rendering an image (say one of the
beauties that appears on this list), I'll render it in the background, using on
of the "disk video" modes and go back to reading mail, etc. while the fractal
renders.

   Do I understand you correctly when I read from your statement above that
such a "disk video" mode will render faster than direct display while rendering?

I emailed an answer back as opposed to posting it. A portion is copied here:
"When you wrote:
"The Nerve of this guy!"

and expressed some exception being taken to the comment the individual
made, may I suggest that his intent was very likely not to be condescending
or insulting. He may have just been having a bad day, perhaps frustrated at
this or that, and wrote in a manner in which he did not intend. This is
very easy to do - I've done it myself, we all have. It is best, usually, to
just let items which may have irritated you to slide by with no response
whatsoever. A _very_ net savvy person who is one of the best in the country
at computer knowledge and so on once wrote concerning "flames" and the
like: "The best response is no response."

I think what the person may have been attempt to say which came across
wrong was that often most questions concerning fractint can be answered by
looking in the documentation that is integral to fractint. While it is true
that the documentation provided with many programs can be sparse and
insufficient, fractint's documentation is, _without doubt so far as I have
ever seen_ the most complete documentation of any program produced.
Especially freeware. Believe me. I printed the damn (oops) thing out - to
the tune of somewhere close to 300 pages! Covering everything in the world.
In fact, the documentation is so massive it is almost too complete. This in
and of itself can be daunting to look at, especially if one is unfamiliar
with the program and is still new to making fractals and so on. In this
case some questions which may be covered in the documentation may very well
be expected...

My biggest embarrassments come when I cannot find a procedure to do
something in a program I have, including in the docs and so on, write up a
question concerning it, email the question, and 30 minutes later while
going through the doc's again, or more likely just tinkering with the
program, find the answer myself. And then I get to sit back and wait for an
email answer and you know the person answering is thinking: "Hasn't he even
looked?" But it happens. Nothing to be really concerned about...

Point being intuitively self explanatory.
Thanks for bearing with me...

Rob,

 - I run Fractint 19.6 in a virtual DOS machine under OS/2 Warp 4.0.  It runs
 - very, very well there.

OS/2 has always had extensive options for DOS boxes that makes it far more
flexible than DOS boxes under Win95.

 - Do I understand you correctly when I read from your statement above that
 - such a "disk video" mode will render faster than direct display while
 - rendering?

Generally, I would think yes, but it depends on the specific image.
However, from your previous message I see you are using a Cyrix 6x86, which
does not have the same problem that PPro and P-II processors have when
accessing video RAM.  If you're considering upgrading that computer, I
would recommend an Intel processor over AMD because the floating-point
performance--what fractals depend on most--is much better on Intel chips.
I switched from a 6x86P120+ to a Pentium-166 and got a much bigger speed
boost for fractals than just 40%.  And FractInt's not even Pentium-optimized.

BTW, Pentium-II processors have MMX support.

"MMX II" may be different though.  What I've been reading is that they
extended the SIMD approach to floating-point computations, which could
imply that an inner-loop M-set computation might be able to compute 8
pixels at a time.  However, I think the bailout test might put some
flies in that ointment.

Actually, you can do better than that. With a copy of the help
compiler, you can actually directly edit the *.src files, compile
them, and add them to fractint.

The only limitation of this is that if you want to change the hot
links, you need a C compiler. My point is that no programming skills
are needed to edit the documentation as long as links aren't changed.

We'd love to have volunteers help with the docs. If anyone would like
to do this, let me know.

If AMD's 3D extensions to MMX are any indication, then MMX-II will allow
two single-precision floating-point operations to be performed in parallel.
 The problem with this approach is that like MMX, which only allows
multiplies on 16-bit math, single-precision floating-point just doesn't get
you very far with fractals.  And you only get to do two of these at once,
not eight, so the speed-up will at most be only two-fold.

I happen to agree with Jay about lesson pages needing to be easy to access
and am planning on re-doing my artsy navy blue pages in pale gray shortly.

Regarding the documentation discussion, my own solution to many of the
points made is to post as much tutorial information as I can on my
homepages and link to other tutorial or discussion pages to provide an
alternative to documentation.  I will be adding links to Jay's section and
BillNY's material when I re-do my Fractint lessons/hints section. I too
tried to read the documentation that comes with Fractint....which really is
excellent and quite thorough......when I started a year ago.  However, I
don't have the math/programmer's mind that absorbs information in that
format......it simply didn't "click" until I joined this list.

Perhaps what we need is "tutorial stone soup" which Noel might help out
with by adding some links to the existing tutorial pages. Then the
tutorially minded among us could simmer our hints and lessons pages and
link to each other. The folks on the list would be benefited by being able
to refer the befuddled to the tutorial links.  What do you think?

Nother topic....

Tim made a call for suggestions for better color maps to bundle with
Fractint.  I'm certainly willing to offer up my favorites which include
maps I've "borrowed" from Chessiecat, Gumbycat, Sylvie, Les, Paul
C....well....my list goes on and on.....plus some of my own. I don't
believe this area should be left to just one or two people as we all have
strong color preferences and the bundled maps ought to provide a sampling
of what I think of as "map types".....i.e. maps with gradients of varying
periodicity (new word), stripes (yuck), areas of black.....etc. Good maps
make for good fractal images and are particularly important for the
beginner. Please email me at

[e-mail]

if you would like to discuss this topic. I volunteer to "hold the
paintbrush" and compile suggestions.

Umm..  I played around with that image from the par i sent a little bit ago,
and it seems to me like 17-digit precision is the magic number.  You won't
get the detail you want without this many, or more.  It seems to me that if
the # of digits is less than 17, all the images (i.e. the one at a spot for
15 digits, and the same spot at 14) are identical.  But, if you move from 16
to 17, you immediately notice the difference.  MUCH more detail, and no
solid blocks.  I find this somewhat odd; I've never had it happen before.
However, the params I used for the julia set were very very precise, with 20
or so digits.  (I zoomed in on an m-set and found a mini-brot, and used its
coordinates as the params.)  That may explain why, but I never tried
changing them...  a little change in the params can be a BIG deal :)

I put both in the same file and renamed the old one with an appended
letter.
Then see if the images are the same with the new one.  If they are not,
then
the formula is not a replacement. If it is, then you can choose which you
like better, for speed, easy understanding, ...

That is the nature of the web.  People will make links to the sites they
think
are helpful or interesting.  There are right now a few links which help
with
Fractint issues. They could be better 'linked' and when that happens, a few
will become good entry points for the questioner.  Right now, a long time
starting point for me is Spanky which I point to from my site.  Another
starting
point is the sci.fractals FAQ.

Any one heard from Dr. J and his Fractal of the Night stuff?  :-)
I've been way to busy with my night shift product testing to check up on
him.
From the looks of some messages I'm getting from fractal space, I think he
wants to get some new information out, but I just don't have time. Maybe
soon.  :-)

Cheers,
Jay

I tend to go along with IK's view that the clock speed alone should make
the PII's perform better.
Here's what I found with one of Brian's own pars -

On my PII-266 (under Win'95), I found
1600x1200, t=3D14m45s (24% faster)
1024x768, t=3D6m36s (192% faster)

hardly a startling improvement (considering that the clock speed is 60%
faster), but a bit quicker nontheless.

It's kind of a cool idea, I guess, but doing the fraction in this manner can
be very slloowww...  :)  I'll show you a better way:

given:

            m
y =  -----------------
      n +     m
          -----------
           n +   m
               -----
                n + ...

you can replace m/(n+m/(n+....)) with y...  i.e.:

             m
y =   --------------
        n   +   y

then solve for y.
you'll get:

y(y + n) - m = 0
y^2 +ny - m = 0

and use quadratic formula...

    -n (+/-) sqrt(n^2 + 4m)
y = -----------------------
               2

This gives you the exact answer for y, without repeating the iteration of
m/(n+m/...).  Therefore, it's much faster.  I hope this helps :)

Thanks - I appreciate the suggestion.  However, it can't be used to
reproduce the images created by my formula.  I wrote this formula as
an extension of my playing around with Taylor series of transcendental
functions.  And, just as log(z^2+1) + c does not produce an image with the
little "dimples" that make it interesting while the first few terms of the
Taylor series of log(z^2+1) + c does, the same is true with continued
fractions.  Using your exact solution produces entirely different
images that lack the small areas of discontinuity which contain
baby Mandelbrots in highly symmetrical (usually) settings.

Sorry for not explaining.

You can delete Bob's original formula and replace it with the if..else
version of the formula which I posted. The revised formula will draw the
exact same images as the original formula, only much faster.

The most recent version of Fractint introduced the use of explicit
conditional branching instructions in formulas, commonly referred to as the
if..else feature. Previously, conditional branching was achieved through a
very creative but time consuming series of formula instructions; Bob's
original Carr3371 is a good example of how this was done. Occasionally,
Sylvie or I will take a formula using the old method and rewrite it to take
advantage of the new feature. Before posting the revision, we will check to
make sure it is in fact drawing the same images as the original formula.
The revision will have the same name as the original, and is intended to
replace it.

What could be done is to use the FRACTINT INDEX at:
    http://spanky.triumf.ca/www/fractint/findex.html
to find pertinent information for a particular area.  Almost all of the
information necessary to use FractInt is available online at the
database.  The only thing that is missing is an easy way to search
through the website for all references to specific keywords.

May be we can talk Noel Giffin into adding the following code to one of
the "major" FractInt webpages at Spanky
_______________________________________________________________________

_______________________________________________________________________

Another possible solution is the use of the FRACTINT.DOC in a word
processor (such as Microsoft Word) that allows the creation of a table
of contents that sends one straight to the page in question, and/or use
of search/find functions.

I could create a Win-95 compatible Help file using the FRACTINT.DOC if
there was a demand for this by the FractInt Developers.  It would take
many hours of work (probably weeks) to get it fully functional with all
of the current data (or the new 2.0 data).  But then a quicker index and
search capability would be available than being on the web or using a
word processor.

Later,
P.N.L.

Hi to those having trouble searching the documentation:

Simply load the fractint.doc into your favourite word processor, I use
wp5.1, and you have all the search and indexing function you would like.

I have a printed out version of the file as well since I  cannot get used to
absorbing text from a screen as opposed to a book.  Very handy for
making ones own annotations to the text, particularly in the vague areas.

Indeed!  Many times I have insulted someone on email, completely
without intending to.  Sometimes email is a weird medium -- you think
you said what you meant pretty clearly, but the person who responds
obviously thinks it's clear you mean something completely different.

If you're dealing with reasonable people, this can often be corrected
by saying, "It sounds like you were trying to insult me.  Is that what
you meant?"  Or, "It sounds like you thought I was trying to insult
you.  That wasn't what I meant!" if you're on the other side.

Also, it's easy for your emotions to run high over email.

Well, it sounds like you haven't used Linux.  This situation is quite
typical of `open-source' software, where anyone can copy, modify, and
use the software freely.  Typically, the people who wrote the software
end up getting asked lots of questions over and over, so, being lazy,
they put the answers in the documentation in the next release so that
they won't get asked so much :)

Also, after you answer the same question in email three or four times,
you have a pretty decent manual page -- all you need to do is add it :)

The usual solution in the Linux world is to write HOWTO documents that
guide people through common tasks.  One HOWTO example -- on how to set
your Linux machine up to use Hebrew characters -- can be found at
<URL:http://sunsite.unc.edu/LDP/HOWTO/Hebrew-HOWTO.html>.

This way, when you want to know how to do something, you check to see
if there's a HOWTO that covers it -- and there usually is, since with
four to ten million Linux users, it's likely that thousands of people
have tried to do what you're trying to do, and some of them have
written about it -- and read the HOWTO.  But if you want to understand
how something works -- or if there's no HOWTO --, you look it up in the
reference manual and get a detailed explanation.

Also, FAQs are often helpful.

This happens to me often.  FAQs help some here, but a well-organized
manual and FAQ is most important in keeping this from happening.

The HOWTOs usually have exemplary organization -- you can usually read
them straight through, but they also have a well-defined (and usually
well-thought-out) hierarchical structure that lets you quickly find the
answer to a particular question.

Indeed.  (Folks: remember this next time you answer a question like
this!) :)

It's also caused by web-browser design problems.  I use Opera

Agreed -- to some extent.  If the artsy stuff actually makes it easier

Yeah, that's no fun.  I like Opera for this -- one quick button and
it's done.

Agreed!  *Everyone* (except web page designers) hates frames.  I
usually turn off frames support in Opera -- and when I have it turned
on, I usually use its `maximize frame' feature, which expands one frame
to fill the whole browser window.

In Netscape or MSIE, I usually unframe myself by opening links in a new
window -- in Netscape, you can do this by clicking on them with the
middle button, and in both of them, you can do this by right-clicking
on a link and selecting `open in new window'.

When Netscape first invented frames, they changed
http://home.netscape.com/ to be a frames page.  They got so many
complaints about it that they turned it back into a normal page.

> Bottom line. Keep It Simple on your study and reference sites.

Keeping it simple, if possible, is good for *any* web site.  (Although
pretty backgrounds are kind of neat sometimes.)

Date: 11 Mar 1998 12:36:03 -0600

Hello fractineers!

Just a public annoucement about my website. I've been getting some e-mial
regarding access to my website. My oh-so-wonderful school decided to charge
all of its fellow students for their web space for web pages AND dialing up
from home. It all used to be FREE. Considering what we all have to pay for
tuition and odds and ends (that don't meet), we pay much more that
expected. It used to be $10 a quarter for about 20 megs of web space. Then,
to use my Institute of Technology(my specific college..a.k.a IT) account at
school, I had to pay another $100 per quarter...plus they give me about 10
more megs. I was kinda bummed out about that, but I got what I
wanted.....mp3, pics, fractals, games.....you name it. And the best part
was, I could download the files at around 50+ kilobytes per second, even up
to 200Kbps. Whereas at home I was at 2-3Kbps.....ack!!!

Now, however, The school has decided to charge us EVEN MORE!!! They erased
ALL old web pages so that they can use that room for something else and
told us to move our pages to a new location on their network and pay MORE.
I didn't read the price, but I can imagine it'll be 2-5 times more
expensive than before and than other dial up charges to access it and the
list goes on and on. You get the jist. So now, I am without a web site. I
hope to pull some strings (so to speak) and get the U of Minn to allow me
some space with out having to pay the extra prices. I'm going into my
finals now, so I'll be busy till mid March perhaps. I have all my pages and
stuff backed up..thank GOD...before they erased my site. So, if I do get
back on with a website, it'll look similar to the ones you've all seen with
some minor changes.

Since I do not have a website anymore, I'll post my par files on here when
I get home. I'm still at the U right at the moment. I have three papers to
write in less than a week's time. UGH!! Then finals....ARGH!! Well, 'nuff
said. Hope for the best, it just might happen.

Try Whole Earth Networks*.  My ISP, a local subsidiary called Hooked,

which would be about the same as the $100/quarter you're paying now.

You might consider going with a commercial ISP.  My ISP, DNACO, sells a
shell account with 20MB of space (web and otherwise) for $14.95 per
month, which adds up to $200 per year.  (Although, if you buy a whole
year at once, they discount it.)

I imagine you can find ISPs in Minneapolis (is that where you are?)
that will give you such things for similar prices.

Bud,

I would try them, but I'm finanacially unstable at the moment. PLust the U
of Minn is very close, so I have some good connection through FTP. Plus they
have some of the best school software around (propriatory though). But I'll
see what I can find.

Karagen,

There are quite a few here in Minnesota....yes I live near Minneapolis. East
Saint Paul. I check the papers often to find some good ISP's. My mouth
waters when I see ISDN or T1-T3 connections. But get stumped when I see the
prices...hehehehe. My page will be back sooner or later. But now...gotta
write my paper.

Happy fractaling

Paul,

 - Then if Fractint seems to run slower than you'd expect on a P-II, wouldn't
 - trying a disk video mode show the "true" speed, by avoiding the video
 - slowdowns?

Not necessarily.  P-II and PPro chips are optimized for 32-bit code, not
16-bit code.  16-bit code does not perform as well.

    I will look into inserting the altavista search engine into the
fractint documentation. I agree that a searchable database would be a
great feature for the fractint docs. It will be a few days before I can
look into it. My web world is crumbling around me at the moment. The monitor
for my PC blew up a few days ago and is in for repair and this morning the
alphaserver which runs netscape under Xwindows crashed during an upgrade.
When I get access to a browser again, I will check out the html insert that
Paul sent.

    As for expanding the docs with other tutorials, I would be happy
to provide links from the fractint page to other worthwhile pages. I've
expanded the existing docs in the past with contributions from
other fractint users. I feel the PHC tutorial, the formula tutorial, and the
L-systems tutorial are great examples of useful extensions to the fractint
documentation. I have hosted them at spanky and done a lot of the work in
converting them to html, but I don't always have time for this. I would
much rather just add links to other pages as long as they are maintained
in a responsible manner and the content stays on topic. My own preference
is for relatively simple organized text with graphics examples to hilight.
I tend to shy away from complex backgrounds or graphics that don't
add any significant information. I think some peoples fractal backgrounds
are very beautiful, but many are too intense and are a distraction from
anyone concentrating on the text. I am also not a fan of advertising and
regardless of personal preference, I am prohibited by campus policy from
adding any to any page that I host.

    A number of people have asked me over the years, why I don't
improve the look of the fractint documents on the web. My main reason
is simplicity. I try to keep the pages as close to the information
distributed in the program as I can. For every new release of fractint,
I have to get a merged list of differences between the old and the new
docs, and apply them to the pages. There is a significant amount of
editing involved, as page references are meaningless, and a lot of the
syntax used in the docs has problems in html and has to be modified.
If I diverge from the existing format significantly, that job gets more
complicated.

    So with all that said, I would be happy to have people contribute
links to expand the fractint documentation. I know there are several pages
out there that have fractint tutorials. I would be happy to link to those
that people here find helpful. I think the big problem with maintaining a
distributed information system is maintaining control of content. I don't
think we need links to 20 tutorials all covering the same topic. We should
have some method of selection and a way to distribute different topics.
A little overlap is inevitable, but we should try to control it somehow.
A lot of topics discussed on this list would make great tutorials. The whole
colouring algorithm thread, the anti-aliasing discussion, as well as
a basic fractint for beginners would be useful in my estimation.
Perhaps we can come up with a voting method or a peer-review process
by the list members here to any pages that are nominated for addition
to the fractint docs.

    Feedback please!

    Cheers,
    Noel Giffin

There is, at the end of the fractint docs - at least in my version of
fractint 19.6, a synopsis of sorts titled: FRMTUTOR.TXT, An Introduction to
the FRACTINT Formula Parser, written by Bradley Beacham. This part is in
and of itself something of a shortened version of the fractint docs and is
something like fractint 101. It is similar in its approach in many respects
to Lasker's Manual of Chess (if you are a chess player you know what I am
talking about) in that it takes one from the very simplest explanations to
the more complex areas very well. Example:

6.2: "...Imagine a cicle drawn on the ground, with a little ball sitting in
the center. We'll pick a spot on the ground, somewhere within the circle,
and call that the 'test point'. Now we will start moving the ball in
discrete steps according to a set of specific rules (which we won't
describe yet) and watch the path that the ball takes."

This tutorial can very well be recommended as a beginning step.

It's a mystery no more, read on...

Assuming you don't specify "recordcolors=3Dyes" then Fractint saves the n=
ame
of the color map in the par as long as you've plugged the map in and done=

nothing else. The moment you cycle that map, even one notch to the left o=
r
right, it's no longer the same as when you first loaded it so Fractint ha=
s
to record the full color code. Try it and see.

Subject: (fractint) Colormap bundling
Date: 12 Mar 1998 00:33:29 EST

    Hi all  - I've newly subscribed to this list, lurked for a little
while, and now
want to tell everyone how much I enjoy the discussions, and add a note
myself.
    I would have kept quiet longer, but for the comment about
bundling better
maps with Fractint, something I've desired since I got into Fractint with
v17. I would
totally like to contribute a map to that effort (as would thousands of
other people,
I'm sure) So what are we to do? We need some sort of voting to be able to
chose
one out of several similar maps. If we need a committee of colormap
experts, perhaps
the reward for serving on this body would be the inclusion of a favorite
map.
This might be overkill. It would be nice to do a really good job on this,
and it's a great
way for non-programmers to contribute to Fractint. At a start, we need a
volunteering
of web space from someone who's got a bunch, so that those who want to
submit can
upload a fractal that highlights their colormap. Then we need some
mechanism
for voting. And, some decisions need to be made, how many maps total, how
many
each of various types of colormaps, etc.  It might be good to have some
examples
of the same periodic map with different frequencies. I find it
exceedingly useful to
have several to apply, as changing this variable - I think of it as speed
or rate of the
colormap -  has similar effects to changing the logmapping - but it
doesn't require
recomputing. I have a few series like this I could offer for
consideration.
    I don't have the answers to all the questions of how best to
choose
the colormaps to bundle with Fractint, but I do want to participate in
the discussion.

    Looking forward to helping make a great program more beautiful,

The current implementation of big numbers in xfractint is awfully
slow, ineficient and badly made.

One could optimize that a lot and use a faster algorithm to multiply
large numbers.

If somebody is intrested in some better algorithm, contact me and I
will give him some sources. I myself unfortunatly don't have the time
to integrate them in xfractint.

May the Source be with you.

Subject: (fractint) Newt6-JAtan-Mset formula
Date: 12 Mar 1998 13:21:24 -0800

Hi Fractintiers,

Way back on Sat, 7 Mar 1998 (hundreds of emails ago),
Paul Carlson gave us Newt5_Atan_Mset, only 4 days after
Newt3_Atan_Mset. These formula along with suitable color
maps give use interesting images with five (and three) color
parts corresponding to the number of roots in the polynomial
he uses in the Newton iteration. As an experiment in
learning how to code these formula, I have written a new
six 'color' formula which uses a sixth degree polynomial.
I've thrown in an extra parameter which turned out to only
be a scale factor.  :-(

Oh well. This formula was featured in Fractal of the Night
where Dr. J is seen lost in a mass of Jello looking for his
Roots.  It was posted to the Fractal-Art list and posted on
my web site along with a little math discussion.
http://home.san.rr.com/jayrhill/FotN/FotN61.html

I have included here some explorations of this Jello formula.
Since it features 6 colors, I am using the not too inventive
primary colors.  It serves me as a 'test pattern' for exploring.

As for my coding of this formula, I have reverted from the
IF ELSE style since I really get tired of typing so many
lines :-) but I have a question. Is the IF ELSE style really
faster in Fractint? It really does not make much difference
in this formula since the tests are not in the loop.

You will also note another method for getting the angle
without atan. This is simpler. And I'm sure wizzle will
like the root formula

R=1-.5*sqrt(5-3*sqrt(5)-sqrt(10*sqrt(5)-50)).  :-)

Enjoy,
Jay

Kragen

        Thanks for your kind words.  So, finally after much puzzling and
much help from you and other members of my faculty, including wizzle,
gumbycat, Jay Hill (whose site I visited and got the Jack Valero SSTOOLS
guide) and a number of other members who responded to my "Help!" cry, I got
an SSTOOLS.INI file made and in the Fractint directory.  Hope my terminology
is correct.
        Now I don't know how to get into it.  Not thru Windows - it gives me
that drop-down box, "Open the program....where made...etc." or whatever it
says.  So I puzzled.  How do I get to that file from Fractint.  I tried just
about every button in the main-menu, used the F1 and studied the aids there,
finally, on a chance, I tried the 'Shell to DOS' (always wondered what that
meant - still don't know) and there I was in DOS - with an ominous warning,
"We're gonna squish that image you still have tucked away in Fractint, if
you...." but took a chance and, after the name Fractint, I typed  dir and
there was an enormous list of my gifs and just about everything else, AND
TRIUMPH!!! there was my SSTOOLS.INI file.  But, sob, I don't know what to do
with it - how to get into it, if I SHOULD get into it, and whether I can
type into it even if I can get it up on the screen in order to enter these
other things I should have in there.
        Just a little more help and I may be over this hurdle too.  One by one.
        Is there a trick to it?
                Thanks,                 Ray

Ray,

The sstools.ini file is an ASCII file. You can edit it using edit.

In DOS window, type

edit sstools.ini

at is the old basic editor from DOS.

To get a DOS window, from Win 95, click the Microsoft window
(wave thing) button on the 'bar' at the (usually) bottom of the screen.
Then Programs and finally MS-DOS Prompt.

use cd C:\fractint   or some such to get to fractint directory.

OR you can use other ascii editors like Notepad or my favorite PFE

http://www.lancs.ac.uk/people/cpaap/pfe

Verson 0.07.002 is out now.

Jay

        Jay

        Your last message turned the tide for me.  Got through to Dos editor
and the sstools file.  Got everything entered, as suggested by Jack Valero,
the piece that I got from your web-site.
        Am now studying the editor and soon will be another couple of steps
forward.
        Incidentally, someone wrote the server wanting to know what kind of
machines various ones were using.  It does make a difference.  I'm delighted
that you thought to give the instructions for the older program.  I have a
Tandy 3.1 with 16meg of ram and I think about 512meg hard drive.  Not very
impressive especially its 33 or 66 MHz speed (or lack of.)  In about a month
I hope to upgrade but will have to get along, as is, for now.
        Thanks again.
                                        Ray

I'd love to find out, but unfortunately I can't come up with a good way
of testing it that _only_ tests the iteration speed.  The problem is
that Fractint draws pictures.  This involves quite a few other factors
(i.e. the time it takes to write a point to screen or random-access
memory, the time it takes to change pixels, etc.)  I suppose if you use
lots of iterations, these other factors would become insignificant, but
then the benchmark simply takes too long.  Nevertheless, I'll try
different methods, tell you what I did and what the results are, and
then you can rip my methods apart :-)

But is any implementation of big numbers in software truly "fast" ? ;-)

Maybe someday Fractint will have different arbitrary precision
algorithims that are good for different situations selectable.  I hope,

Ummm... no thanks.  Let me read through the entire source code for
XFractint first... which should take about 5-6 weeks. <g>

And that's just to find the start of program execution! <vbg>

Also, when you get the windows "open with" box, you can choose Notepad,

Most computers are available with several different MHz speeds, in
the same way that most cars are availalble with different engine
capacities.  It would be rather wasteful to have a different manual
for each speed of computer.  Some computers tell you the speed at
which they are running, every time you start them up: you have to
watch the first few things that are written on the screen (they go
past pretty quickly).  Otherwise you should have a not of the speed
on some of the paperwork that came wth the beast, or perhaps on the
box (some sort of sticky label).

Hi Fractintiers,

Continuing my experiment in learning how to code formula,
I have written another formula, this time with eight 'colors'

Carlson should not have all the fun.  :-)    I should note
that there were errors in my posting (in the commentary)

Ray, I may be misreading your question a little, but in case you've already
edited your SSTOOLS.INI file the way you want it, and are wondering how to use
it in FRACTINT, here's an answer:  it's automatic.  Most folks put instruction
lines in their SSTOOLS.INI file to tell FRACTINT what to do at startup, and also
where to look for various types of files (PARs, MAPs, and the like).  Once those
instruction lines are in your SSTOOLS.INI file, and your SSTOOLS.INI file is in
the same directory as FRACTINT (so that when you type 'dir' at the DOS prompt
you will see both FRACTINT.EXE and SSTOOLS.INI scroll by, along with all that
other stuff that came with FRACTINT), that's all you need to do!  The next time
you run FRACTINT, it will look for your SSTOOLS.INI file, and if it finds the
file, it'll perform the various instructions in the file all by its self.  If
your SSTOOLS.INI file contains the line:

video=F3

you'll be able to tell that FRACTINT and is using the SSTOOLS.INI file because
now when you start FRACTINT, you should immeadiately get a picture of the
Mandelbrot Set instead of the opening credits screen!  If there are instructions
in your SSTOOLS.INI file that FRACTINT can't understand, FRACTINT will let you
know at startup with a little red warning message.  Read this message to
determine which instruction FRACTINT couldn't understand, then edit your
SSTOOLS.INI file to fix the instruction.  If you aren't sure how to fix it, ask
away!

Cheers, Jason

Unless anyone has objections....I volunteer to be the color map

1. Tim tells us about how many color maps he'd like to bundle - 75 seems
about right
2. Color artists submit their maps to me and/or I ask some of the folks if
their maps can be used (I already have some in mind)
3. Maps will be divided into "technical" areas
    Mid-tone gradient maps - with sub-categories for short and long steps
between colors (these are the most useful and also often read as pastels
when cycled)
    Maps with colors plus fair amounts of black
    Jewel tone gradients
    Maps with 1, 2, or 3 colors
    Striped maps (not my favorite so I need help here)
    Specialty maps like 3D glasses (these leave me clueless)
    Anything else I like and find useful or you can talk me into
4. I will post the maps, by category, at my site for viewing and downloading
5. If we have more maps submitted than Tim wants to bundle....we have a map
vote.....say...vote for 5 maps in category 1.....5 in 2, etc.
6. All maps submitted (except in the specialty category) must be able to be
cycled .....please do not submit a map that looks great only with a
particular fractal.
7. Maps will be named to give credit to the author, i.e. wizzle1.map,
gumbycat8.map, carlson3.map

Feedback?

Hi Ray, hope I can shed a bit of light on your puzzlement.

  Firstly, a general comment.  All the problems you cite come
about from the lack of intuitiveness of computer systems.  For
all their power and advancement, they still aren't a natural
interface nor are they a natural way of working.

> I got an SSTOOLS.INI file made and in the Fractint directory.

  OK, sstools.ini is a plain-jane text file.   What you want to
do is edit the text in the file.  Thus you need an editor.

  As I understand you, you're running Windows.  I believe
Windows has an editor called Notepad.  Use that to open
the sstools.ini file and edit the contents therein.

  Cheers,
Rob

I'd like that IF I could actually access Usenet.  As it stands now I can
only access "special" ones that are on their own server, i.e.
3dfx.glide.linux because my school didn't tell us what our default news
server should be.

A newsgroup would be a good idea, but only if the list stays.

Theran,

 - With all the traffic in this list, isnt it time to create a newsgroup?

Not really.  Mailing lists have certain advantages over newsgroups, the
biggest of which is that spam is less of a problem.  There's also fewer
problems with missing posts; far too often I see posts missing from a news
thread.  And for some people, mail is easier to deal with than a newsgroup.

I'd hate to see this discussion move to a newsgroup.

The great disturbance is the Source of email SPAM that
results from posting to a news group. The worst thing I
can vision is a news group echoing my postings to this
forum. SPAMers glean email addresses from those
postings. I have done searches for my name and every
alias I've used posting to sci.fractals and sci.math is
there in these data bases.  There is a news group called
sci.fractals and a binary group for posting images,
alt.binaries.pictures.fractals.

Ob fractals. My last two entries for Fractal of the Night were on the
topic of Newton's method and Mandelbrot sets, a la Paul Carlson.
I posted on my site four quiz questions about these fractals and
what makes them what they are. So far, I have seen no replies.
http://home.san.rr.com/jayrhill/FotN/FotN62.html
and the previous page.  Were these questions too difficult,
obscure, poorly written or just ho hum?  Is there any interest in
this forum for a deeper understanding of what makes these fractals
what they are?  Perhaps there is plenty of beauty derived from
random formulating.  More likely not. I observe a steady
stream of great new formulae coming from Paul Carlson
and perhaps two or three others.  I doubt this is random
formulizationizating.  I suspect strongly that he knows what
he is doing.

.com indicates a commercial enterprise, so it should probably
be .org, but doesn't have to be.

BTW, is it $100 one time, or every year?

please do this before some porno group grabs it.  Anyone who saw the
BAMBI link scandal story about Disney knows what I mean.  In case you
missed it, Disney's site has a search-bot to look up the various
characters in th Disney family, it seem ssomeone messed up and anyone
who typed BAMBI as the search criteria got something just a little bit
different than a cartoon charcter drawing of a fawn.  YEP, you guessed
it.  Yowza. yowza, yowza, what a suprize.

I'd be willing to contribute a little money to this end (Protecting
the FRACTINT name that is, almost sounded like somethin' else there
folx).

Please let me know something on this ASAP.

Subject: (fractint) Thank you note
Date: 13 Mar 1998 21:59:17 -0700

        I have enjoyed your humor, wisdome and good advice, even when I was
sitting in the shadows, spying on the group before I joined.  I felt a
little like an 007 character, but I have discovered that more than I have
sort of "checked it out" before making the move.  I almost did not venture
in because it IS intimidating for a non-technical person to read all that
very "in" talk.
        The truth is, I love generating fractals to such a degree that, in
spite of my reluctance I leaped in feeling I was sure to learn.  It may be
slow, because there is so much, but I will.
        The final condition of my joining was because in spite of having
generated somewhat over 2000 images through Fractint, I still felt like I
was on the most basic and elementary level with many mountains to go.
        I AM learning, day by day, and have been given direction and areas
to explore by so many of you in this participation.
        Incidentally, I still stand by my insistance that the docs should be
written by non-programmers - or by secondary authors who must learn what
they are writing about, not by experts who know so much that it seems simple
to them.  A prime example was the other evening when I entered Jay Hill's
web-site and down-loaded a sort of tutorial by Jack Valero on SSTOOLS.INI.
        To begin with it was a very valuable piece for me to have.  I got a
lot out of it - and, here's the BUT - for instance, the questioner was
asking how to enter an entire par file into fractint (a problem I must face
some day).... and Jack's reply was, "Press the 2 or SHIFT-@ key on the top
row of your keyboard.  This will let you load pars into Fractint."  He knows
what he is saying and he knows what the next procedure is, but he has NOT
answered the question..."how do you ENTER the pars into Fractint...."  not
where is the door.  Yes, it is important to know where the door is, how to
unlock or open it - but to the absolute beginner the relieving answer is not
there yet.  Yes, a person cannot be hand-held, he must do some investigating
himself, but certain mysterious - and NEW procedures must be introduced to
him.
        Well, I do ramble on.  This was to be primarily a thank you note and
has turned out to be a monstrous harangue.  Sorry.  BUT....
Fractals are my hobby!  and  I occasionally have bouts of "Temporary sanity"
and I don't know what to do about it, except rave!
        Thanks for listening and thanks again for advice well given.  I
assure you that it has been well taken.

                       Ray

I really like this group- It's lively and there are a lot of
very smart,  creative people who are kind to newcomers.
Generally people are careful to stay on topic, but you get a sense
of who they are.  There's quite a range of ages and interests.
I would hate to see anything change the basic
structure.  Traffic is kind of high, but you can just hit delete if it's

not of interest to you.

You questions are interesting, and very much at the level that
I would like to understand this stuff.  ""A" is just for scaling" - just
the
sort of thing that I want to know and slowly figure out.  I'm sure the
major figures in this know the answers and are not going to post
them.   I think other people are quite varied in their approach to it.
I work in an unrelated and  demanding field, and I really like to
come home and do this- tend to read the mail and doodle around with
pictures nearly every day.  I am interested in the theory but save them
up
for times when I have energy for real thought- e.g. printed them out and

took a bundle on vacation,  impressing my friends.  Anyway, don't stop
doing it, and if you don't get an answer right away it's not for lack of
interest.

I use a Matrox Millenium II 8 megs that came with my Dell. I think that
it's great for Fractint, but then, the only other time I have used fractint
was a long time ago on a 286 (yikes!) It really screams on this machine.

(Copied straight from the interNIC's faq)

"The cost for registering a new domain name in .com, .org, and .net is
$100 (US). This fee covers the initial registration and updates to the
domain name's database record for a period of two years. Following the
initial two-year period, registrants will be charged $50 (US) annually,
on the anniversary of the initial registration, to renew the domain
name. The renewal (re-registration) fee also covers updates for that
year. The billing contact will be sent an invoice by postal and
electronic mail 30 days before this fee is due.
Updates that are not covered by this fee are: changes to the domain name
itself; transfers of the domain name to another party; changes in the
Organization's information that in effect represent a transfer of the
domain name to another legal entity. These actions are not considered
updates and require a new registration to be processed, which will be
subject to the $100 (US) new registration fee. "


fractint.org and fractint.com are both available.  The cost is the same
for either.  The registration process looks painless enough, and details
are available at the interNIC's site:

This is like magic, getting the par file started. It is a lot like making bread
or
yogurt.  If you have the starter bacteria, you can make more. Otherwise,
getting started is tough.

Let's say someone, or you even, make a formula which you have in a
file named ClassicM.txt.  You may have just copied it from email into
notepad which seems to insist on calling it a .txt file. Or you may
have used an export feature of your email. Anyway, you want to see
what it does. I'm going to assume the formula has a new unique name.
Suppose it looks like this:

frm:classic-M1 { ; Jay Hill, 1998
; requires periodicity=0 and outside=summ
continue = 1,
z = 0,
zc = c = pixel
   :
if (|zc| > 4)
    continue = 0 ; we want to stop
else
    zc = sqr(zc) + c
endif
continue == 1; keep going while continue is 1
}

You can rename the file to this ClassicM.frm so Fractint can
find the formula as it scans all the .frm files in your Fractint
directory.  This is the usual way we do this and there are
even some organized files available at Spanky
http://spanky.triumf.ca/www/spanky.html
with alphabetic sorting of the formulas. But here you need
to do one thing to make it work. Remove the frm: from line

frm:classic-M1 {

so that the formula reads...

classic-M1 { ; Jay Hill, 1998
; requires periodicity=0 and outside=summ
continue = 1,
z = 0,
zc = c = pixel
   :
if (|zc| > 4)
    continue = 0 ; we want to stop
else
    zc = sqr(zc) + c
endif
continue == 1; keep going while continue is 1
}

This is the format of formulas in the frm files.  Now start Fractint,
hit t and see the formula types menu screen.  At the top it says...

fn*fn          fn*z+z         fn+fn          formula        frothybasin

use the arrow keys up to and select 'formula'.  Press Enter and see
the selection of formulas in the fractint.frm file. We are looking for
your formula in a different file. Press F6 and see something like this...

Select Formula File
Template: c:\jay\fractint.196\*.frm

This is the directory which should have your file. Select classicm.frm.

Formula Selection
File: c:\jay\fractint.196\classicm.frm

  classic-M

Now select classic-M press enter and see

Parameters for fractal type formula

Since we don't have any parameters to play with, press enter again, see

                        Select Video Mode
key...name......................xdot.ydot.colr.comment..................
F2    IBM 16-Color EGA           640  350  16  Standard EGA hi-res mode
F3    IBM 256-Color VGA/MCGA     320  200 256  Quick and LOTS of colors

Select the mode you want and you will see the image with default colors.

The image looks awful, for it is supposed to be the Mandelbrot set.
We need, for this formula, to set a few parameters like periodicity=0
and outside=summ.   I find it easier to set these up later.  Now
we can create a par file which gets us started with this formula any
time again quickly. Press B and see

Parameter file  c:\jay\fractint.196\fractint.par

Put the cursor in this line and edit the file name to look like this...

Parameter file  c:\jay\fractint.196\ClassicM.par

Put a name in file to name the image and when you are ready, press
enter to save it.

Now with an ASCII text editor, edit classicm.par adding the commands
you need for the formula. I like to add a line to indicate the image name
so when someone makes the image, they can save it with a name
which makes sense and is the same as anyone else would name it.
It might look like this...

classic-M {  ; Ray Montgomery, 1998
reset=1960 type=formula formulaname=classic-M1
periodicity=0 outside=summ
center-mag=-0.75/0.0/.4/1/0
float=y maxiter=256 inside=0
savename=classicm
}

Now let's try it.

Go into Fractint, press '@', 'F6', and select 'classicm.par' from
the list of files.  See the menu...

                 Parameter Set Selection
                 File: c:\jay\fractint.196\classicm.par

classic-M       Ray Montgomery, 1998

Select classic-M, press enter, select video mode, and see the image

That is better, having the right parameters helps.  Now start exploring
in your new formula. Try colors and options. But remember certain
restrictions apply to certain formulas, this one needs 'outside=summ'
so if you go into the X menu, don't change that one.

One last thing. When you post your images, be sure to include colors
and the formula.  Save images with B making sure the line

 Record colors?  y

says 'y'.  To keep track of the formula, I put the formula right
in the par file containing pars which use it, right at the top.
Do it this way, with the frm: in front, including author and
any other remarks you may need for reference.

comment { ; from Jay Hill's monstrous harangue }
frm:classic-M1 { ; Jay Hill, 1998
; requires periodicity=0 and outside=summ
continue = 1,
z = 0,
zc = c = pixel
   :
if (|zc| > 4)
    continue = 0 ; we want to stop
else
    zc = sqr(zc) + c
endif
continue == 1 ; keep going while continue is 1
}

Although you could write all your frm and par files from scratch, I like to let
Fractint do some of the work and do lots of copy and paste.

You should see the documentation of the final acceptance test of serious
software. Every step is written out and expected results indicated. I have
sort of done that here, since it seemed called for this time. After 10 hour
days of running these tests, I'm beginning to think that way.....

Hope this helps.

$100 for 2 years then $50 per anum heck yeah that\'s damn reasonable!

Who do I send the money order to (I prefer M.O.\'s)

I DO NOT suggest myself BTW I\'m absolutely dreadful at money
management even when I have some.  8-I <-- My no sense of money
management and I\'m ticked off at myself face.

Anyway FRACTINT.ORG has a very cool ring to it IMHO.

Once again Who do I send the MO to?

And just as important :

When or how soon?


This is almost exciting!  8->   <-- goofy grin.

Domain Name Registration:

Registering a domain name with Internic Software will cost US$250.  This
cost covers NIC fees for two years and their service fees.  After two
years, you will be billed US$50 by the relevant registry authority
(called the InterNIC operated by Network Solutions, Inc..) to renew your
registration.

There are currently 210 Fractint subscribers and 61 Fractint-Digest
subscribers.  If divided up equally among the number of members on the
discussion list, it would amount to less than a dollar apiece.  In fact,
it might cost some individuals more in postage than to pay that small of
a percentage.

There are three different types of domain names that you can register.
The general purposes for these domains are listed below:

  .COM   Commercial
  .NET   Network
  .ORG   Miscellaneous Organizations

Every domain requires that you set up your DNS before applying for your
domain name.  To set up a DNS you have to make entries for your new
domain on two separate machines connected to the Internet.  These two
machines are called Domain Name Servers, and are referred to as Primary
DNS and Secondary DNS.

Most people don't have their own DNS but just want to reserve a name for
future use.  If you just want to reserve a domain name, then you may
have a problem.  One option is to contact a local Service Provider and
start paying monthly fees even though you are not using the name.

Another option, without additional charge, is that Internic Software
will set up DNS for your domain(s) on its machines.  This DNS setup up
is temporary and can NOT be used for web site hosting.  You can change
your DNS at any time by simply modifying your domain name information.

If you want to use your own DNS, simply fill out the DNS information on
InterNIC's online secure order form.  They will use this information
when they submit your application.

If you just want to secure your domain name (so that no one else can
take it), InterNIC will set up your DNS so that your application will be
accepted.  Just get the name for now and then transfer it over when
you're ready to use it.

There will soon be new high-level names added to the list available, but
this may not happen until sometime around September (depending on
current bureaucracy).

  Probably the .org domain would be more strictly correct but the
.com domain might be more useful.

  For instance, if you registered www.fractint.com, then anyone
using Netscape could just enter "fractint" in the Open dialog box and
Netscape would automatically resolve this to www.fractint.com.  I
don't think that a .org domain would be resolved.

  For most of us, whether it's .org or .com wouldn't matter but it
would be much easier for new folk to find a .com address.

Cheers,
Rob

Perhaps Tim et al would like to follow the model of POVRAY and go for
fractint.org.  Povray is a freeware ray-tracing program that was written
along the same lines as Fractint--massive contributions, a main core of
programmers, freely distributable, wonderful software.  Tim and other
Stone Soupers may have even been involved in povray's development.

Check it out at www.povray.org.  It has support for ray-tracing 4d

For those who haven't seen my web site, I wanted to let you
know about a feature that will be going the way of the dinosaurs
shortly, due to an arbitrary server storage limit.  I have recently
touted Whole Earth Networks as an ISP worth checking into,
but their policies do have some downsides.  For $25/mo I get
full Internet service and 20 MB; to expand, I can pay an extra
$35/mo per 5MB or pay $100/mo for their "professional" account.
Not so hot, eh?  Actually, there is a less painful way, which
involves buying a second account and linking directories (so
$50/mo for 40MB).  In any case, I can't afford it.

The feature, "A Fractal Voyage", is no big deal.  It's just a deep
(although not by Fractint standards) Mandelbrot zoom,  but it has
a bit of a detective story behind it.  It will be there for two more
weeks.

If you want something that's a little bit better, why not go for
www.fractint.ca?  After all, the main pages are on spanky.triumf.ca,
which sorta indicates that Canada is Fractint's home already.  Plus .ca
almost reminds me of ChAos! :-)

I just wonder what the restrictions are on using domain names reserved
for countries.  Does someone in that country have to register or what?

Just my $0.02 US (which is about the price domain names SHOULD be --
someone's getting awfully rich off of them!)

It sure does, but everything *except* julibrots. It does 4D
quaternion and hypercomplex fractals. I know because I programmed
this (in collaboration with others). I should try adding julibrots
too.

I'll respond to suggestions about domain names a bit later. I think
we should do it, but there are some issues to think through.

FWIW, you are right about www.povray.org, but we Lee Crocker uses
piclab.com.

I wouldn't object.  Canada is a nice, clean, modern, democratic place,
and its governments generally don't stick their collective nose into
other peoples' business or threaten to bomb them back to the stone
age (not that I think Saddam deserves any slack).  Hell, If I were two
years older (just turned 40), I might be living there instead of here
(USA; that pesky Vietnam thing, you know - 58,000 dead Americans,
and a lot more dead Vietnamese, for nothing).  The climate's a bit chilly,
though.

Word!  I just about passed a golden egg when I saw that $250 note.
That's why I don't have a domain name; I refuse to feed The Beast.
Wouldn't pay federal income tax, if I thought I could get away with it.

Perhaps it would be better to let the authors decide what to name the

descriptive names -- or whatever else they choose.

64 gigs is reasonable these days.  I saw a supposedly-working 6.4G
drive sell on auctionweb yesterday for $225.  Probably you could put
together 64G of drive-space on a single machine for $3500 max, and
maybe much less.

(I'd be doing RAID4, though, with that much disk -- afraid of disk
failures if I had ten disks!)

I imagine the 64G is for fractals, though :)

Actually, it costs the InterNIC approximately a dollar per domain per
year to maintain their database.  (And that's not counting the extra
services they provide, like randomly suspending your domain because they
forgot you paid, taking weeks to update your records, yanking your domain
because they decided that someone has a trademark on it, etc.)

I suggest that Tim register `fractint' as a trademark (which, I think,
costs $250) to give us a little safety.

> Who do I send the money order to (I prefer M.O.\'s)

I suggest Tim, as he's the current head of the development group.

> When or how soon?

InterNIC is very quick about creating new domains, since that's what
they get paid for.  Usually your domain will be happy the day the check
arrives -- or, if you pay by credit card, within minutes or hours.

The potentially slower part is finding two people with 24-7 Internet
access who are willing to act as DNS servers.  Lots of companies will
do this for you if you pay them, though.

Ideally, it should be two *different* entities, so that if there's a
flood in California, your DNS server in New York is still alive.

It varies from country to country.  For example, Tonga
(http://www.tonic.to/) registers domain names (at the same rate as the
InterNIC) for anyone in the world.

Canada (http://www.cdnnet.ca/) charges no fees (yet) for domain-name
registration.  There's a note on the introduction page:

Please note that the CA domain is for Canadian organizations.

The .ca registration process apparently takes a minimum of a week, and
apparently essentially requires that you either own a trademark or be
incorporated, in Canada.

According to
<URL:http://www.sec.gov/Archives/edgar/data/1030341/0000950133-97-003997.txt>,
Network Solutions' net income for the third quarter of 1997 was
$12,172,000.  (During the rest of 1997, it was $30,896,000, for a total
of $43,068,000.)

I've been called a lot of things, but never a dirty, lowdown

Seriously, my formulas usually do have some kind of logic to
them.  I've pretty much stopped putting a lot of comments in
my formulas because I sensed that not many people were interested
in how the formulas worked and those that were probably didn't
need the comments.

On the other hand, I have been thinking about posting a rather

I see that the domain .com has been explained in previous postings. The
domain .org is for non-profit-making organizations such as the American

Paul,

 - Registering a domain name with Internic Software will cost US$250.

Congratulations, you just got bilked.  Internic Software has nothing to do
with the InterNIC.  Internic Software is www.internic.com; the InterNIC is
www.internic.net.  Internic Software even says so, right on their home page.

The Internic Software price is inflated.  Many ISPs will offer you the
"service" of handling the domain name registration for you, but charge an
extreme price.  Their price may also include their own cost for "setting
up" the virtual host on their end.  The raw cost for registering a domain
name is $100, which is good for two years; after that, it's $50 per year.
I know, because I recently registered my own domain fractalus.com (and
because the InterNIC's FAQ still says it's $100).

The biggest problem is not the $100, but coming up with two domain name
servers for the new domain.  Typically, you must coordinate this with your
ISP or whoever is going to host the domain, and this is a big chunk of what
you pay money for.  After all, they are providing space and an IP address
for the domain (on one of their own servers, which acts as a host for lots
of virtual domains).  It pays to shop around for this, as rates vary widely.

One alternative to consider is a service like NameSecure
(http://www.namesecure.com) which will provide the DNS hosting and redirect
all web visitors to your domain to any URL you specify.  This is cheap, but
unless you have a server with its own IP address, the URL will change once
visitors arrive at the new site.  Still, it does let you reserve and use
the domain.  NameSecure charges $50 for the first year, and $25 for
subsequent years.

If that's a little too much initial outlay to get a domain started
(remember you still need to pay the InterNIC fee) then you can work through
GeoCities, which has a special deal with NameSecure.  GeoCities will give
you 3M for free, but if you sign up for GeoPlus, which is $5/mo., you can
get 15M of space.  Once you're in GeoPlus, you can then use NameSecure for
$5/mo. (rather than a $50 up-front fee).  This works out to $10 more for
the first year, but it's a little easier to swallow.  GeoCities is not an
unreasonable way to start hosting a web site; I ran fractalus.com from
there until December.

My two drachmas worth:

I believe that the filename for a color map should be descriptive of
what the map looks like. If I saw wizzle.map, for instance, how would I
be able to remember that if had the colors, for example, blue, silver
and gold? Naming it something such as bluslvgd.map would be more helpful
in color map selections. If two or more people send in color maps with
the same name, such as orngblue.map, then they could be renamed
orngblu1.map and orngblu2.map.

Kragen,

 - InterNIC is very quick about creating new domains, since that's what
 - they get paid for.  Usually your domain will be happy the day the check
 - arrives -- or, if you pay by credit card, within minutes or hours.

My experience was that when InterNIC got my registration, the domain was
turned on.  I was billed by Network Solutions a week or so later, and I had
something like 30 days to pay the bill.  But the domain was up and running
long before I had actually paid for it.

 - The potentially slower part is finding two people with 24-7 Internet
 - access who are willing to act as DNS servers.  Lots of companies will
 - do this for you if you pay them, though.

Right.  I'd do it, but the company I work for has decided they're going to
start charging for such services. :(  Doesn't affect me, but it means I
can't host other domains for free.

 - Ideally, it should be two *different* entities, so that if there's a
 - flood in California, your DNS server in New York is still alive.

Ideally, but in practical situations it's less of an issue.  If my primary
DNS is in California, and so is my server (common) then it doesn't matter
if I have a backup DNS in New York, because if there's a flood in
California my server's underwater anyway. :)

Would this be Pseudo-3-D Rendering Methods for Fractals in the Complex
Plane that appeared in Computers & Graphics, Vol 20, No.5, in 1996? If
so, I'm sure many programmers would be interested in your paper. This
was truly a well-written and informative report on Paul C's methods of
obtaining his gorgeous 3D effects.

OK, so someone from Canada registers Fractint as a trademark and then
applies for the domain name.  Although then it would cost as much to get
fractint.ca as it would to get fractint.org... :-(

Guess that won't work.  And www.fractint.to  doesn't make much sense
either.

Sounds like www.fractint.org is the choice then.

No, what I had in mind was something more basic and detailed than my
Computers & Graphics article, which was written assuming a certain
level of knowledge of complex variables.  Also, the article (which I
actually wrote in 1995 - it took a year for it to be reviewed and
published) did not include some ideas I've come up with since I
wrote the article.

Okay, so I do engage in a little random formulizationizating

I just pulled out of the air - they have no significance that

Subject: (fractint) Pseudo 3D and Orbit Traps
Date: 14 Mar 1998 23:02:49 -0600 (CST)

Several people have indicated an interest in how I use orbit traps
to get a pseudo-3D effect in my fractals.  The following is an
attempt to explain the methods using as little math as possible.

I guess a good place to start might be to explain how I happened
to develop the 3D Stalks rendering method about 3 or 4 years ago.
I had written a program that plotted fractals using Pickover's
epsilon cross method.  With this method, when the orbitting point
lands within a specified distance, "epsilon," of either the real
or imaginary axis, bailout occurs and the screen pixel is plotted
in a color depending on the number of iterations at bailout.  The
result is an image consisting of stalks, each stalk being a solid
color.  I noticed that if I made epsilon smaller the stalks became
thinner and if larger the stalks became fatter.  I then modified
the program so that if the orbit point fell within a distance
epsilon of an axis the pixel was plotted red, but if the point fell
within a distance of one-half epsilon the pixel was replotted green.
The result was red stalks overlaid with green stalks about half
the thickness of the red stalks they were laying on.

These experiments showed me two things:  1) each stalk represents
a single iteration count at bailout, and 2) it was possible to
vary the color of the stalk depending on where within epsilon
the orbit point fell.  My first 3D Stalks image used only shades
of yellow - from bright yellow if the point fell exactly on one of
the axes to dark yellow if the point fell a distance epsilon away
from an axis, with intermediate shades of yellow for points falling
between those two extremes.  I used 250 shades of yellow, the
brightest at colormap index 1 and the darkest at colormap index 250
and the rest varying linearly in between (I usaully save colormap
index 0 for black since this is the overscan or border color).  My
program computed how close the orbit point fell to an axis and if
it was within epsilon the distance was saved in a variable "dist."
Then the ratio dist/epsilon was computed (call it "ratio") and used
to compute an index into the colormap as follows:

    index = 1 + ratio * 249

This gives values of index from 1 to 250 since ratio varies from
zero to one.  The resulting image consisted of yellow stalks, each
stalk being dark yellow at the edges and bright yellow in the center,
giving the stalks a 3D appearance since, everything else being equal,
bright portions of an image appear closer to the observer than dark
portions.

The next step was to break the colormap into two color ranges, index
1 to 125 light yellow to dark yellow, index 126 to 250 light blue
to dark blue.  The yellow range was used if bailout occurred on an
even iteration, the blue range if on an odd iteration, ie,

   if even, index =   1 + ratio * 124
   if odd,  index = 126 + ratio * 124

or, in general:

index = 1 + range_num * colors_in_range + ratio * (colors_in_range-1)

where range_num varies from zero to the number of color ranges minus
one.

This illustrates the basic pseudo-3D orbit trap method:

If an orbit point falls within the trap, compute the ratio of the
distance from the orbit point to some point Q in the trap divided by
the maximum distance from point Q to the boundary of the the trap
(this guarantees that the ratio will be from zero to one, inclusive)
and use that ratio to index into a color range.

Orbit traps can have many forms.  The main requirement is that the
test for the orbit point falling in the trap can't take too long to
execute since the test must be done every iteration.  Simple closed
areas like circles and squares make good orbit traps since it is easy
to test if the orbit point falls within them and it is also easy to
compute the ratio using the center of the area as point Q.  Plane
curves expressed in parametric form also make good orbit traps
except in this case the trap is a narrow constant width band with the
curve at its center (ie, for a circle the band would be a ring).
A formula I posted some time ago using an astroid curve illustrated
this: the argument of the iterated variable (the counter-clockwise
angle from the positive real axis to the orbit point) is computed
and used to compute the coordinates of point Q on the plane curve.
If the orbit point is within the specified distance of point Q,
compute the ratio and color index as above.

Sometimes for special effects I'll use color ranges in which the
colors do not vary linearly.  Sometimes I'll have the darkest shade
at both ends of the range with the brightest shade in the center of
the range.  Sometimes I'll use the ratio squared which emphasizes
the colors towards the beginning of a range.  Because the ratio
is always from zero to one, it can be raised to any positive power
and still be from zero to one.

The same general method of using a ratio between zero and one to
index into a color range is not limited to orbit traps.  In my
Atan method, for example, I use a ratio of angles.

To use these methods with Fractint I had to find a way to get
Fractint to use the computed colormap index.  I do this in my
formulas by iterating some variable other than z and by keeping
my own iteration counter.  Then when the point falls in the
orbit trap I set z equal to the colormap index minus the number of
iterations.  This works when outside=summ is used which adds
the number of iterations to z.

That's all I can think of for now.  I'll be glad to answer any
questions.

Makes me wonder how I'm managing with a measly 2.5 gigs, of which 300
are FreeBSD now and the rest are WinBl... oops, I mean Windoz... <smack>

Oh yeah... I don't make very many GIFs of fractals! because mine all
suck! :-)

Maybe the PNG format will help that (the size not my skill as an
artist).

For $8 the name fractint.base.org can be pointed to the spanky server.  This
is not the best solution, but it's maybe the cheapest and simplest...

Well, you have to realize that I have about 400 megs of MP3's, and about
500 megs of textures that I use for 3d work, and web pages. I really do
waste a lot of space. Although, I would love to waste a lot more!

I too can't wait for png to become more supported. the lastest version of
the two major browsers support them, but not all thier functions. (the
alpha channels, most notably) I'd really love to make my graphics fade into
my background better, but it's still not supported! Ack! hurry it up Netscape!

Sure....I'll try anything

The maps in the last two pars are worth comparing. The very last par has
Paul Carlson's colorful map and the par right above it has one of my
modifications of that map.  I've found it a particularly good one for
coloring julias.....just stick the darkest and lightest colors of the area
you want to change where paul did.  I also varied the map with areas of
black. It's been great fun to work with. I asked Paul if we could use the
map in our new set and he graciously agreed....no voting on this one!!! It
goes in as it is so technically useful.

During the decision period I'm going to name the maps for people because
that will help me keep straight whose maps I've posted and whose I still
need to post (I'm starting ....but slowly). We can have The Great
Nomenclature Debate after we figure out which maps are the ones we want to
bundle.

The people approach also helps me during this period because I'm trying to
request permission to use some of the maps that come with the pars posted
here.

It wouldn't. I just tried it with aclu and it tried to contact
www.aclu.com! Of course, when I originaly went looking for the ACLU's
homepage, I tried www.aclu.org from the very start, because I knew it
was a nonprofit organization.

But it would mistakenly identify Fractint as a commercial product. To be
honest, I would be more inclined to trust a "free download" from a
fractint.org than a fractint.com.

When I first heard about fractint in a graphics programming book, I
tried fractint.org right off the bat, then fractint.com, then yahoo.com.

Any domain would be better than what fractint has now, but lets make it
express fractint's nature as a freeware, volunteer supported, program.

Subject: (fractint) Submitting Colormaps
Date: 15 Mar 1998 10:08:12 -0800

Please select the maps you submit to me with some degree of care and I
would prefer maps in a variety of categories from each person. I have
established the following categories

1. 123 Maps - maps with 1, 2, or 3 colors
2. Midtones - those trusty gradients with two sub-categories ....maps with
long versus short intervals between colors
3. Blacks
4. Jewel tones
5. Stripes
6. Specialty

The naming of maps for people is working well for me as I then don't have
to sort thru to find if I have the same name among hundreds of maps
(yes....hundreds already). For future submittals please re-name your maps
with your name....i.e. wizzle1.map wizzle2.map, etc.

I am clearly going to have to do some pruning among the maps submitted
since I can't post hundreds of gifs.  I think I will impose an arbitary
limit of 20 maps per person posted but zip up the whole shebang so everyone
can see what was submitted, if they like. How does this sound?

The definition of RAID I'm familiar with is Redundant Array of
Inexpensive Disks.  RAID 4 simply means 4 disks daisy chained together
unless the acromyn has been redeifned and I missed it.  Freakier
things have happened.


Hope this was semi-psuedo-sorta-kinda-quasi useful.

This is probably off-topic for fractint; I'll send you a description in

Subject: (fractint) gravibrot: a technical question
Date: 15 Mar 1998 11:51:53 -0800

While I'm no math slouch, I am not really good with fractal set
theory.  While investigating gravibrot, I have encountered a
disturbing phenomenon.  As opposed to every other fractal
I have previously dealt with in any detail, where the set
boundary is relatively stable with respect to bailout value,
most of the gravibrot set boundaries undergo gross changes
as "bailout" varies.  These changes are not resolved by
increasing "maxiter".

Is something wrong with my formulation, or are multi-function
fractals just fundamentally different?


Thanks, Bud

Date: 15 Mar 1998 12:41:35 -0800

I have received maps from Linda, Bud, Marie Drozis, Kerry (incomprehensible
to me), Damien, Morgan Owens and Sylvie. Did I miss anyone?

If anyone besides Kerry sent me a list of numbers (which I thought were
just a mistake), please re-submit the maps to me......remember that I am
very simple minded. I did not realize that numbers meant maps.

Progress to date.....

I've sorted Linda's, Bud's, Damien's and Marie's maps into the categories.
I only got 5 maps from Damien...is that right? Sylvie and Morgan's
submissions should be sorted by the end of today...so see???? it's not that
bad of a job.

All the maps are GREAT, BTW......if I "cut" a map it's because I'm getting
a way lot of great stuff!!!!

A note......making up the rules here as we go......if you adore a map
currently in the standard fractint set...please submit it even if you are
not the author. My idea is to have a technically superior set of maps to
make all of your fractals glorious.

Tim reminded me to remind you that any map submitted will flounder into the
public domain.....so don't submit anything you think you could copyright. I
suspect that after the upcoming nomenclature debate is done....the maps
will lose any sense of identity. I too like maps I can identify easily.
Won't it be nice when we have long filenames some day? <<hint hint to the
programming division>>.

Is this even possible?  I know good maps are definitely products of
considerable effort, but I didn't think you could copyright a color
scheme.  When applied to a copyrighted image or registered
trademark, it's a different story...

Here's my two cents worth:

Wizzle would like us to submit them with an identifying name.  She gave
examples like wizzle1.map, carlson2.map, etc. (I used Lindaxxx.map, since
gumbycat takes us the whole 8 digits and leaves no room for numbers.)
Given Wizzle's volunteer status on this project, I think we should comply
with her wishes, rather than pursue our own direction and thereby cause her
additional work.

However, once the maps are chosen, then maybe the authors could elect to
keep the name under which that map was submitted, or change it.

Whatever we decide, I think we must ask Wizzle, not dictate to her, how she
performs her volunteer function.

So . . . Wizzle . . . what to you think?

Paul Derbyshire,

I like your Nova formulas, they rock!!! I used the one for Fractint, but it's seems
to be jumbled or garbled when I use the floating point algorithm. I do not like the
looks of it with the it. Do you have a better formula? Or do I have to alter the
program myself? Becuase I have no clue how. I think I might fudge up the formula
even worse. Thanx in advanced.

It is probably not possible any more than it is possible to copyright a
recipe......a book of recipes...yes....but a single one..no.  Nor can a
math formula be copyrighted....along with a bunch of other stuff that can't
be. But people persist in thinking they can copyright anything that is
applied to paper.

Try turning off periodicity.  Press "g", type "periodicity=no", press RETURN.

Yes, I only sent you five maps.  You want more? :)  Most of my maps are
done by hue-rotating a few basic maps that I make using a graphics package,
so I didn't want to overload you with a bunch of maps that were different
color variations of the same light/dark theme.  I can send more.  My maps
tend to be very simple.

Linda...

Thanks...that is right in line with my thinking. Now that I've started the
project it seems we need to go in steps.

1. submit and sort maps
2. get them up for review (I plan on a zipped file and gifs at my site)
3. narrow down the many many wonderful maps submitted to a reasonable
number.....we will prolly need a discussion about what the criteria ought
to be for this....but that is tomorrow's problem.
4. name those maps selected in some reasonable way.

Having gotten introduced to this group during the great Fractint Contest of
1997, I'm sure everyone will have an opinion about steps 3 and 4!!!!!  My
job is to get us that far.....<<grin>>

I'm posting this reply to the list rather than just to Damien because I
have already discovered some very interesting things by reviewing the maps
submitted.

First and foremost.....people appear to gravitate toward a single
"technical area." By this I mean....long gradient maps....maps with 1,2 or
3 colors, standard gradients, etc. Everyone also seems to have a strong
color preference. I happen to avoid orange and yellow....modifying them in
my maps to peach and light gold.

Hopefully one of the outcomes of the map exercise will be to get us all
trying out new sorts of "stuff." I'm now thinking of zipping the submitted
maps by category rather than as a giant blob so folks can stretch into new
areas. Feedback?

If I was able to sort the maps quickly...one day...it is because I looked
at them from a purely technical standpoint.....how fast did the colors
change....how much black.....were there oddly defined periods or the abrupt
changes that signify stripes? I tried to make no judgements on colors used.

One of the reasons I separated the maps into categories is because that is
a useful way to quickly improve an image. Rather than floundering among
dozens of possibilities.....I check out an image with all my
categories.....then narrow into the ideal map.

I'm learning lots just by looking at your great maps...thanks so much!!!

Angela

comment { commentary by Mark "Bud" Christenson 3/15/98

To those who have been waiting, my apologies; I have been busy,
and it has taken a while to select just one good example for each=20
type.  The .pars are, with one exception, by the author of each=20
formula.

For those with Fractint 19.6, you can copy everything from the=20
start to just before the signature text into a file with the extension
.par, move it to your Fractint directory, and load as usual.   For=20
those with older versions, you will have to copy the parameter sets=20
into a *.par file, delete the frm: prefix from the formulae and copy=20
them into a *.frm file, and load as usual.

I am posting this to the Fractal Art list by request, and to the Fractint=20
list to provide all existing formulae, and one example of each type,=20
in one location.


Enjoy, Bud

P.S.: Sylvie, I only had one example of gravijul-v2 from you, and it=20
wasn't periodic.  I hope you don't mind me using my own, since tiles=20
are one of the formula's coolest features :o)

comment { commentary by Mark "Bud" Christenson 3/15/98

*** This is a second post.  Sorry (especially for those on both lists)=20
 for the lack of a subject line in the last post ***

To those who have been waiting, my apologies; I have been busy,
and it has taken a while to select just one good example for each=20
type.  The .pars are, with one exception, by the author of each=20
formula.

For those with Fractint 19.6, you can copy everything from the=20
start to just before the signature text into a file with the extension
.par, move it to your Fractint directory, and load as usual.   For=20
those with older versions, you will have to copy the parameter sets=20
into a *.par file, delete the frm: prefix from the formulae and copy=20
them into a *.frm file, and load as usual.

I am posting this to the Fractal Art list by request, and to the Fractint=20
list to provide all existing formulae, and one example of each type,=20
in one location.


Enjoy, Bud

P.S.: Sylvie, I only had one example of gravijul-v2 from you, and it=20
wasn't periodic.  I hope you don't mind me using my own, since tiles=20
are one of the formula's coolest features :o)

Subject: (fractint) Another contest?
Date: 15 Mar 1998 16:53:12 -0700 (MST)

Fractinters,

Is it time for another contest?  I propose a theme of best/most
interesting coloring of the standard Julia and/or Mandelbrot sets.  Maybe
we all start with 3 coordinate files (1 c range for the Mandelbrot set and
2 sets of a c value and z range for 2 Julia sets), and are free to color
them as we see fit.  This wouldn't limit us to a particular formula, as
many coloring schemes can only be done in Fractint by using a different
formula.  For candidate coordinates, maybe a zoom into a Mandelbrot
midget, a Julia set of a main cardioiod boundary point with an irrational
internal angle (to give lots of interior space and chaotic orbits), and a
Julia dust (c outside of the Mandelbrot set), to show off expertise in
outside coloring.  I volunteer to either be heavily involved, or not.  :-)

What do you all think?

Kerry

Contest, cool idea. And do you mean you wld be in charge (that's another
great idea). How about a third, Nova type just to make it a little funkier.
Then we cld have best M-set, best Julia, and best Nova.

Wow! Someone actually thinks I know what I'm saying!
I haven't been reading the mail here lately so I'm sorry if this reply is a
bit
late. You are right, I didn't mention the next step. But if you follow those
instructions, you'll find that the Fractint screen takes over and tells you
the rest of what you need to know at the bottom of the screen. Basically, use
the arrow keys to select your par entry and then press the Enter key... and
that action loads the par information into Fractint so it can use it. The same
screen also tells you how to switch to another par file. I didn't mention
this as it didn't seem necessary to duplicate what Fractint will tell the
user anyway.

However, it is possible that you might be asking not how to get the par file
into Fractint but how to get Fractint to find the par file in the first
place. If I recall correctly, I covered that in the section about creating
directories for various Fractint support files and how to make sure Fractint
knows about them via the SSTOOLS.INI file.

I hope this helps. Actually, I was surprised that someone kept a record of
my message. It wasn't intended as a tutorial but simply as a late night
quickie reply to someone's difficulties. If you still are having problems
email me directly and I'll try to help. By the way, I am *NOT* a Fractint
expert by even the most stretched imagination!

And you're right. This mail list is a wonderful resource filled with equally
wonderful people. I just wish I had more time to read the massive mail
quantities it generates. Have fun and enjoy the group. They're definitely
worth your time!

I love the idea of another contest because I learned so much from the first
one. I'm assuming by coloring the standard Julia/Mandelbrot sets you mean
via those intriguiing methods such as you and Damien come up with. That is
way beyond me but I'm already picturing the oodles of new goodies that
would become available.

I say go for it!!!

Nother thought......the rest of us could get in on the act by submitting
pars based on the new coloring schemes.......the scheme with the most/best
pars wins!!! And so does everybody else cause we all got to play.

It shouldn't garble with float=y. Are you sure you've used periodicity=n?

Subject: (fractint) tiling...gravijul-2u
Date: 15 Mar 1998 22:26:33 -0800

It kind of slipped by without comment- I really liked the
gravijul-2u variant and pars that Phil DiGiorgi posted as a
first contribution to this.
      The later gravijul formulas all make many different really nice
tilings.  I wonder if someone can point out what part of those
formulas gives the capability for all the tilings.

Something when I forgot to mention when I submitted my "Heat" map is that I
filched it wholesale from Photoshop's "Black Body" colour table.

But does anyone want to bet that Adobe holds any ownership on Planck's
radiation law?

I've modified Paul Carlson's frm slightly which optimized by Sylvie by
adding a function variable and the whitesq variable.  Lo and behold there's
a manblebrot in every formula.  An interesting pulsating effect can be
achieved by hitting the down arrow keys 10-12 times and then hitting the
number 6 or 7 on the numbers (or whichever combination one prefers)

Subject: (fractint) gravijul pars and examples - rev 2
Date: 16 Mar 1998 10:47:26 -0800

comment { commentary by Mark "Bud" Christenson 3/16/98 (rev 2)

** Note: this is an updated post with a previously overlooked
formula and two new pars **

To those who have been waiting, my apologies; I have been busy,
and it has taken a while to select just one good example for each
type.  The pars are by the author of each formula.

For those with Fractint 19.6, you can copy everything from the
start to just before the signature text into a file with the extension
.par, move it to your Fractint directory, and load as usual.   For
those with older versions, you will have to copy the parameter sets
into a *.par file, delete the frm: prefix from the formulae and copy
them into a *.frm file, and load as usual.

I am posting this to the Fractal Art list by request, and to the Fractint
list to provide all existing formulae, and one example of each type,
in one location.  I will post updates periodically, but if it gets too big
I will have to post the file on my web site.


Enjoy, Bud

Subject: (fractint) Colormap Questions
Date: 16 Mar 1998 13:17:38 -0800

Couple of questions to folks whose email addresses I don't have

1.  Phil D....you posted some pars this month and several I think ought to
be included in the colormaps I'm collecting...any objections if I grab what
I want? You had a stripped map I thought was very useful.
2.  Where are colormaps from Alice and Janet??? One of the colormaps Alice
used for her contest submittal is, I think, a real winner in the short
gradient category and we ought to see at least something from the 1997
Great Fractal Contest winner and Queen!!!

Alice....can I use your map?

Map count by category to date (after I pruned) is

1. 123 maps - 16
2. blacks - 6
3. jewels - 11
4. short gradients - 7
5. specialty - 4
6. stripes - 3
7. standard gradients - 33

total 80

I still have 32 to evaluate and put into categories.

We may not need a run off at all if we are willing to go with 140 or so
maps. I do want to add some more maps to this total...the more useful ones
from the current set plus some of the intriguing ones posted to the list.
Does anyone know the number of maps now bundled with Fractint?

If we decide to limit ourselves to 100 or so maps, it seems reasonable to
have the run-off in the 123 and standard gradients categories only.

Feedback?

Angela

    Paul, If you are willing, I'd be interested in turning
this into a fractint tutorial hosted at spanky. If you could
supply a few formula and images to demonstrate your methods,
I think it would make a nice one. If you would rather host it
at your own site where you could maintain and revise it, I would
gladly provide a link to it.

Well, I don't know yet... but I'm working on it.  Something puzzling has arisen,

check this for yourself (if you use the method I describe, everything breaks

    Hi,

    Here are some of my thoughts on the fractint.org issue.

If we want to register fractint.org then pay the $100.00 dollars
and register with internic.net for the 2 year term. Don't bother
trying to register with a service in another country. They are
fine if you are only interested in local/domestic service in that
country but none of the international traffic will be able to find
the site because none of the big DNS databases will pick it up.

    One big question that I have, is where is www.fractint.org
going to point to? It's one thing to register a name, but it takes
some thought and effort to administer a site as well as manage
content and control system resources. Commercial web hosts typically
charge between $20.00 and $50.00 dollars a month for about 10 to 20
megabytes of storage and many of them charge more after a certain
number of hits or after so much data has transfered. The ones that
I have looked at, allow about 10-100 megabytes per month transfer or
about 1000 hits/month before charging more on a per hit or a per
megabyte rate. This isn't really enough when your going to
host something as popular as fractint. The spanky fractint pages
currently average about 2000 threads a day and move about 200-300
megabytes a day all from a database of about 100 megabytes and that's
just at my site. I don't know how much traffic hits the mirror site
or how much goes to some of the galleries and pages I link to.
Hosting www.fractint.org might prove more than we can afford unless
someone like Rich Thompson at X-mission or myself, or Michael
Taylor at Mt. Allison, who have the resources available, could
host them free of charge.

    I know the webserver software that I use at spanky is capable
of multihoming, so in theory I could set up to respond to calls
to www.fractint.org and pass them off to the existing fractint pages,
but I'm not sure I wouldn't run into trouble/problems with people
here who manage the triumf.ca domain. I will have to make some enquiries,
if that is what we decide we want.

    Cheers,
    Noel Giffin

Jason,

The equation for the boundary of the main cardioid is:

r = 0.5 * (1 - cos(theta))
x = r * cos(theta) + 0.25
y = r * sin(theta)

for the period 3 bulb, theta = 1/3 * 360 degrees = 120 degrees, so

r = 0.75
x = -.125
y ~ .64952 = 3/8 * sqrt(3)

which corresponds to what you got with Fractint.

Noel,

 - The spanky fractint pages currently average about 2000 threads a
 - day and move about 200-300 megabytes a day all from a database of
 - about 100 megabytes and that's just at my site. I don't know how
 - much traffic hits the mirror site or how much goes to some of the
 - galleries and pages I link to.

Well, I can tell what mine are. :)  Last week fractalus.com got almost
62,000 individual hits; that includes all requests for HTML files, GIF
files, etc.  Transfers total more than 900M of bandwidth.  That's roughly
700 hits to Sharon Webb's gallery, 260 to my own site, and 85 to Alice
Kelley's gallery.

That's one very typical week.  Not as much traffic as spanky, but if I were
hosting it at a place that charged me by bandwidth or hits, I'd be in
pretty far over my head.

 - Hosting www.fractint.org might prove more than we can afford unless
 - someone like Rich Thompson at X-mission or myself, or Michael
 - Taylor at Mt. Allison, who have the resources available, could
 - host them free of charge.

Or unless a free/inexpensive hosting service like GeoCities were used,
which is less than desirable.

 -     I know the webserver software that I use at spanky is capable
 - of multihoming, so in theory I could set up to respond to calls
 - to www.fractint.org and pass them off to the existing fractint pages,
 - but I'm not sure I wouldn't run into trouble/problems with people
 - here who manage the triumf.ca domain. I will have to make some enquiries,
 - if that is what we decide we want.

If someone besides triumf.ca is acting as the DNS for the domain, then
there's very little triumf.ca has to do besides let you use an IP address,
and *possibly* fill in a reverse-lookup entry to their own zone files that
resolves the IP address back to www.fracting.org .  If you want triumf.ca
to act as the DNS for fractint.org, then they need to do a lot more.

    Well it's too much hassle to extract the exact info from the
logs to say how much traffic is fractint related and how much is
just general fractal traffic at spanky, but I think I would
estimate about 1/2 below is fractint.

In terms of hits and bytes at spanky:

 file hits    80000 hits/day
 Direct I/O:    600 Megabytes/day

    Please not geocities! I hate their little pop-up advertising
windows.

    While the above is true logically, it is a different story politically
and administratively for me. The triumf.ca domain is the domain maintained
by TRIUMF, the research lab that pays my salary. So far they have been
very tolerant of my endeavors in hosting fractal related information, but
the official line is that it is outside the mandate given this facility.
If I cause too many waves, I might sink the boat.

    Yes, I could get another IP outside the 142.90  triumf.ca domain
but I am physically on a network that is within their realm. Without
their cooperation, I don't get anything passed to me. The triumf DNS
server has to recognize the new IP or it will not pass information.
Right now they typically reject all packets not addressed within the
domain. So I either need fractint.org to reflect an address within
the 142.90 domain or I have to beg the network guru's here to make
an exception in my case and pass thru info out of their recognized
domain. Not a likely scenario.

    Noel Giffin

I'd be glad to have you host it.  I'll see what I can put together.
Did you see the explanation that I posted?  Do you think that woud

        Hi Rob....

        Thanks for the advice.  Every little bit helps.  I'm hoping against
hope to get a new computer in a couple of months (And, naturally, that will
make me, automatically, a better computerist and Fractinter, won't it?
(Sure it will.)
        Seriously, I am hard at  work,--hitting the books, as it were, about
moving around in DOS.  Never done it till Fractint.  Got out my idle
'Dummies' (oh, lord, I said it, right out loud!  Forgive me please!) Dos,
Windows, PC, manuals, for keyboards, monitors, cups (even CPUs) and just
about everything I can lay my hands on.  Even brought home a book from the
library thinking it would help but it turned out to be a book on how to
program for Windows.(Ugh!)
I'm even considering adult classes on computers at my local Adult Education.
        Anyway, thanks for the advice.  My computer is Windows 3.1.

REGISTER DOMAIN NAMES FOR LESS
Network Solutions, the company in charge of registering .com, .org and
.net domains, is phasing out the $35 Intellectual Infrastructure Fund
fee.  Effective April 1, registering domain names will cost $70 for two
years, with $35 annual renewals.  Too bad all the best names are taken.

I'm familiar with the GNU stuff -- after all, I run Linux at home --
but what I'm interested in is the `bazaar' model.  Linux was developed
using it, Fractint was developed using it, but most GNU stuff was not.

This is not correct.  I frequently access sites registered in .de, .fr,
.ca, and .jp, even though I'm in the US.  I can even send mail to
walsh.tj, which is registered in the Tajikistan domain -- although it's
actually located in Fresno, California.

I'm certain someone will want to do this.  I'd say, let's stick with Spanky
until the load gets too heavy for you, and then look for hosting elsewhere.

Actually, you don't even have to use a separate IP address.  Netscape
and MSIE since version 3 send a header telling the server what name it
was looked up by; Apache, and presumably other web servers, can use
that to determine what pages that client sees.

`A lot more' really wouldn't be much more, given that triumf.ca already
has nameservers set up.  They'd just have to create another zone file
with about six records in it and add it to their nameserver
configuration.

Hi all...I have two questions about Makemig and Simplgif. My apologies if
the answers are obvious/already answered/buried in the docs!! First, is
there a way to use these two applications with pars that have had
symmetry written into them? I am having no luck here. Second, I have a
par that I have to go through and write in bailoutest=imag, due to the
infamous bailoutest bug. Naturally I want a multi-part par that has as
few parts as possible to minimize the tedious editing. I have a par that,
after this (making a 6400x4800 sized fractal in 16 parts), Makemig does
fine with, and then Simplgif (yes, the new one) just mangles. If anyone
has a clue I'd be grateful.--Alice

Sheesh....I didn't know it's takes this much hassle just to decide on whether or
not to get a domain. Just think of what hassles wil arise when Noel does get a
domain. He'll be swamped for weeks.

Anyways, if one will be obtained, count me in. I'll contribute what I can into
purchasing it.
It is too good of an idea to waste.

  Ray,

I did the same thing when I got my computer. I read all the DOS commands and
learned what a mouse was and keyboard was and......etc. I felt like a moron. But
in the long run, it helped me immensely. Don't ask me to program though. GAWD!

I've been around computers for 3 years now, and I think I've accomplished quite
a lot. I'll still have to ask some genius to show me how to program though. But
that can wait a bit. At 21, I think I have quite a way ahead of me.

    Hi Paul,

    I've been following your posts to the listserv a little.
I think I read through your short intro to the orbit trap fractals.

    I've also gone through a few of the parameter collections
and recreated a few of your images and looked at the formula used.

I think there is enough new material there to make a really good
tutorial. I can't seem to find your brief intro anymore though.
Could you email me another copy and I will read it more carefully
this time.

    This could indeed be incorrect. I have only limited and
out-of-date experience with this. I know when I was setting up a friends
business webpage here in Canada about a year ago, I was told that while
it was cheaper to register in this country, it would take a lot longer
for the registered name to propogate outside the country and it
might not be as widely recognized than a US registered site. That was
with the ".com" domain. I understand that using the country domains
like ".ca", ".fr" etc, would allow nameservers to follow paths to
designated nameservers for each country or region, but we were talking
about using ".com" or ".org" and I wasn't sure how these get shared
if they are registered in a country other than the U.S.

    Cheers,
    Noel

Hi to everybody !

Since to release of the fractint version 18.x (don't remember exact
which one) I have always enjoyed to look at those great pictures.
As the times passed by and with the growth of my theoretical
knowledge of the theory of fractals an idea aroused in my mind. I
tried to understand the mathematics behind all those beautiful
pictures but soon I saw that my mathematical borders were reached.
And at this point I will piont out my idea: I'm studing biology at
germany and imaging that one day every biologist will use the
mathematics as a tool for their interpretations. So what I wanted to
do is to build a formula that represents a biological process, say
somethink like a real prey-predator model, and calculate it in the
complexe plane. Is there anybody who is interested in this idea and
willing to help me ?

Bye, Mike

This formula makes use of a hypocycloid curve.  The images are
kind of interesting.

Subject: (fractint) Script for pars in xfractint
Date: 17 Mar 1998 22:36:29 -0600 (CST)

If anybody else out there uses xfractint I wrote a handy little shell
script to scan through a par file and generate a gif image for each
parameter set.

I have found it very handy for going through large par files and for
many of the posts on this list.  Just start it running and come back in a
little while to view the collection of images.

One warning, this is an ugly script and I'm sure that there are better
ways to do it, but it does work.  First it creates a temporary script and
puts a bunch of calls to xfractint into it.  Then it runs the script that
it generated and saves all of the images into files.

I called it pargen so to use it:

> pargen parfile.par image-prefix

The image prefix will be appended with 001 so that the image indexing
works correctly.  Remember to keep the prefix short to avoid problems with
long file names.

#!/bin/csh -f

echo "#\!/bin/csh -f" > temp-image-script
chmod 755 temp-image-script

grep '{' $1 | \
awk '{print "xfractint @'$1'/" $1 " batch=y savename='$2'001 -disk"}' \
>> temp-image-script

temp-image-script


Have fun,
Mike

        Hi, Morgan! I lock myself in the closet, use a flashlight and read

I've been known to carry a PC 'Dummies', quite openly down the street.

While you're there, check out the other lakes. What's cool is that the

Enjoyed Lake #2 the best, but couldn't get #4 and #6 to work.

     Why do most folks hate cynics so much?

        Lav....Hi!
                Went to have a look at your lakes but I was denied access.
And, a strange thing happened, - I can't remember the exact words but a
large, imposing drop-down box took over the whole screen, looking as though
it were from some out-in-space official dept., saying in effect, can't get
in folks - and even stranger, on the address line, the one that ends with
'htm' - the htm had changed from htm to Java.  I know for a fact that I
typed htm and nothing at all, whatsoever about Java.  I changed the Java
back to htm, went back in and the 2nd time, got no drop-down box as before,
but just could not bring anything up.  You have a nice looking page, I
commend on that, but no matter where or how I clicked no image would appear.
Just black.
        Well, I tried.  Sorry I missed it.

Very cool!!! I had no trouble seeing any of the lakes and I think you did a

that's why I did well.

What program did you use for the landscapes?

Cool lakes.  Ken Musgrave's "Other State", "Emil", "Zabriskie Point", and
"Parabolic Curves in the Plane of the Ecliptic" look great with moving lakes.

Ok here's the scoop on the lake.

I didn't make the java applet for the rippling effect. They were made by David
Griffith. It was a spare of the moment thing late last night.....1-2 am!!!! I
didn't get to finish it all, but thought you guys might like to see it. I
touched them up some more, so all the info ( I think that's all of it) should
be posted now. Go to:

http://www.tc.umn.edu/~nguy0505/Lakes/Lakes.htm

Ray, I'm sorry you couldn't see it. It's really something. Perhaps you should
get Netscape Communicator 4.0 or later and setup it up to your preferences and
go try it.

Have fun!

I call this formula my Celtic formula because about a year
ago I posted the image produced by the first par to the
abpf newsgroup and Noel Giffin wrote to me saying he really
liked it because it reminded him of some kind of Celtic
symbol (I don't remember what).  Anyhow, I was able to
recreate the image in Fractint and here it is.  I also added a
second par that produces another image with a Celtic look to it.

Subject: (fractint) Strange Newton-like formulas
Date: 18 Mar 1998 15:45:23 -0600 (CST)

I originally programmed these equationss a long time ago
and, quite frankly, they dont make a whole of sense to
me now.  It looks like I started with a Newton equation
and then added a little bit of random formulizationizating.
However, after translating them into Fractint formulas
they still make some very nice images and the formulas
are fun to experiment with.

Thanks for the info, Kerry!  Am I correct in my interpretation that the shape of
the main cardioid is therefore *not* a 'perfect' cardioid?  I.e., the method I
described of rotating one circle around another at my webpage
< http://boralf.agsci.colostate.edu/~jason/fracpages/geo_mset.htm >
will not accurately describe the actual Mset?

If this is the case... well, there'll be some rethinking to do, at least!

Cheers, Jason

Your rolling circle model is fine, just be careful in the math....

Date: 18 Mar 1998 20:46:26 -0500

I was doing some zooming on the mset, and I decided to try a repeated
zoom...  I started with the midget at -1.75,0 and zoomed at the midget that
cooresponds to itself; i.e.,
the new midget : (-1.75,0) :: (-1.75,0) : the main mset
Over and over and over again, and I realized that a familiar number was
coming up, sqrt(3).  Atleast I think it was that... I'll have to double
check.  Anyways, the center of each successive zoom approached closer and
closer to that.
I just thought it was kinda cool and interesting...  Email me back if you
figure anything out. :)

i recently bought a new video card for my computer which is a 486
66mgz.the video card i bought is a Diamond Speedstar 64 2000 Graphics
and now fractint does not work in the video mode that i always used
shift 7 or is it f7 1024x780 and works with most super vga.i had no idea
that there would ever be a problem with this or would have paid much
more attention to what i was buying as fractint is on of my favorite
pastimes on the computer.i have tried to read some of the documentation
with fractint on the video drivers but dont quite follow what it is i am
supposed to do.my computer literacy only goes so far.if anyone could
advise or help me i would be most grateful.i have had fractint since
version 16.? and it was one of the programs that really sparked my
interest in the computer. thanks dudley

I get the limit as -1.78644025556369

Of course I could have lost lock and zoomed into the wrong one.....

It's not the sqrt of 3.  I went as far as I could go and got
-1.7864402555..., the same as Jay.

I agree with Jay.  And if anyone's got 25 Megs to burn up, I've got a 421
frame 320x240 avi that shows the zoom from a magnitude of 1 to 10^12.

Wow Kerry,

Talk about quick analysis!  Peter posted the question only about 5
hours ago and you have 421 frames already!??!@?!  This and a
few more like it might make a good CD.  I had to change color
schemes at least once while I did the zoom. It gets a little messy
near the arbitrary precision limit.

I might add that we KNOW sqrt(3) is wrong because

sqrt(3) > -1.75  = base of period 3 midget

which is on the wrong side.  The limit is on the '-' side of the
midget so we must have

limit<-1.75.

Subject: (fractint) Fractals Just Went Nuclear!
Date: 19 Mar 1998 02:44:35 -0500 (EST)



Introducing the Nuclear formula.
3 Julia parameters.
3 Critical points.
3 6-dimensional Mandelbrot sets.
9 Mandelbrot slices.
3 Quadcolored Mandelbrot slices using all 3 critical points.

Short PAR included, many more parameters to come.

And preliminary exploration has turned up structures in the Mandelbrot set
(see PAR entry fracmini_zoom2) indicative of Herman rings lurking in the
Julia equation...

The last image, fracmini_zoom1a, is currently generating in a window in
disk video.

The formula parser chokes on Nuclear_M_k if disk video 1024x768 or bigger
is set, but not with normal video or smaller disk video modes. Suspect a
bad interaction between disk video code and formula code, which would have
been avoided if Fractint had been written in C++ (shameless
C++/objects/encapsulation/information hiding plug here!). When the parser
chokes it displays a red error box and emits a buzz, then generates a
blank image. The precise error message resembles "Not enough memory for
'formula'", and is useless, since it is clearly wrong. (I have enough
memory to run "formula" types; obviously, or I'd not have all these PARs
from hring and so forth...)

Reminds me of release 6 of the IBM/360 operating system years ago. No matter
how simple my FORTRAN program was, I even had 3 line subroutine stubs like

SUBROUTINE X
RETURN
END

the compiler emitted this message

Care to explain your formula?

By the way, Paul, you should get a kick out of the last three issues of
Fractal of the Night beginning with
http://home.san.rr.com/jayrhill/FotN/FotN61.html

Peter Jakubowicz has taken a swing at the quiz questions posed there.
He and I are wondering what you will make of them.

>Care to explain your formula?

It colors in one of 4 ranges based on what happens to all 3 critical points.

All escape -> The largest of the three iteration counts chooses color from
range 0.

2 escape, 1 does not -> The largest iteration for the escapees chooses
color from range n, n being the critical point that found a finite
attractor. So, for example, a mini Mandelbrot for critical point 1 in and near
which critical points 2 and 3 escape, will be colored from range 1, the
surroundings from range 0, and dendrites in the surroundings caused by
critical points 2-3 will be seen intersecting the mini Mandelbrot! The
mini's own dendrites will show up outside the baby, where they will
overlap other dendrites from 2 and 3.

1 escapes, 2 stay but don't converge -> Escaping picks color range and
colors by its iteration. So if two minis intersect, the intersection will
"null out" to the third color range, and still the dendrites are visible
through it.

1 escapes, 2 stay and hit same attracting cycle or point -> Whichever
critical point hit the finite attractor first (determined by rerunning the
iterations), the other picks the range, and the specific color by
convergence speed. So if you have a minibrot for critical point 2, and
in a region inside it critical point 3 converges to its attractor instead
of infinity, there will be a blob of color from range 3. It will in fact
typically look like a Julia set corresponding roughly to where in the
minibrot it is located! Picture a seahorsey connected Julia set embedded
in a mini Mandelbrot near its seahorse valley inside the cardioid.

None escape: If they all converge to separate attractors, the color is
color 0. If two meet the same attractor, the second one to do so picks the
range and color. If they all meet the same attractor, the last chooses the
index and the color comesfrom range 0.

OK...will do. Make something of them that is. No guarantees as to what, yet.


BTW I came up with the formula quite simply. I wanted a generic rational
function with critical points at -1, 0, and 1. So I supposed I had
r(z) = p(z)/q(z) and noted the zeros of the derivative would be zeros of
p'q-pq', so I set p(z) = az^3+bz^2+cz+d, q(z) = pz^3+qz^2+rz+s, and
[p'q-pq'](z) = z^3-z. This led to a collection of nonlinear constraints on
the 8 unknowns. I found these virtually intractable and arbitrarily chose
p = 0. Eventually I derived all the others in terms of a and c, and so the
formula was born, with a and c variable. A square root of 3 popped up,
interestingly in light of the earlier discussion of sqrt(3). I added a
constant to the formula to generalize it further (constants don't alter
the derivative). Since the rational evaluated to -ac at z=0, I chose the
constant at the end to be ack, so that k=1 would produce a
convenient superattracting fixed point at 0.

A quick check with w = 1/z and s(w) = 1/r(1/w) verified that infinity was
superattracting. (s had a zero at zero and also had a derivative a
multiple of w^3-w, so the critical points z=w=1, z=w=-1 showed up again as
a check on my math, and w=0 meaning z=infinity as well.)

Have you run the PAR file and/or explored?

Subject: (fractint) Thanks par, volume 1
Date: 19 Mar 1998 03:56:41 PST

Having been a lurker now for some months I finally found the time to
 play around with fractint and to put some things learned from this
 list into practice.
Perhaps I'm a  bit too enthusiast but I would like to share the results
 with you.
Consider it as a big thank you to all contributors.
I had some trouble copying the whole par into one mailnote, so it comes
 in 4 volumes.
Most of the FRM's come from the orgform collection.

Greetings to you all,

From: "Koppens,Ton" <[e-mail]>
Subject: (fractint) Thanks par, volume 1
Date: 19 Mar 1998 03:56:41 PST

Having been a lurker now for some months I finally found the time to
 play around with fractint and to put some things learned from this
 list into practice.
Perhaps I'm a  bit too enthusiast but I would like to share the results
 with you.
Consider it as a big thank you to all contributors.
I had some trouble copying the whole par into one mailnote, so it comes
 in 4 volumes.
Most of the FRM's come from the orgform collection.

Greetings to you all,


Ton Koppens

Try Damien Jones' JuliaSaver. I just installed it yesterday and it is nice:
<http://www.fractalus.com/juliasaver/>

My favorite screen saver is The Psychedelic Screen Saver. It is not
strictly fractal but it has lots of options, some of which I'm sure use
fractal math:

How about Fractint?  There's a little program that I've used (I think
it's at spanky) that calls (DOS) Fractint as a W95 screen saver, but it
really sucks cycles (they're fractals, what did you expect?  :-)  )
It's called Fractint Screen Saver and it's from Thore Berntsen.

        I have a program, bought by mail, called "FracShow".  Is is a CD Rom
disk.  It has about 2000 images on it that run, fading in or fading out,
made from all the recognizable types, Barnesley, etc..  It can be programmed
in a myriad of ways including a kaleidoscope, and image over image, etc..
It is a great program to sit and watch while listening to some good music.
        It has a facility that can "grab"?  an image off the screen that can
be stored in your wallpaper file for use as a wall-paper and I think you can
also "grab"? one for use as a screen saver.  I love the program but I can
not be sure just what all it can do.

As much as I like fractals, I do not like the Fractint screensaver. It takes so
long. I'm still running at 100mhz, so you know how that feels. I'll just stick
to the ones on my screensaver site. Otherwise I'll have to make the fractal
images into gif/jpegs and use a simple screensaver that just displays pictures.
It's a thought. I'd love to see my Tiera-Zon and Flarium fractals on those.

Hi Wizzle !

I wanted to try something different if it is possible at all: I
wanted to try and get a set of raw material. I will catch some beetle
the coming summer and so there are the caughts of one summer. Maybe I
can get the caughts of some previous summers, so one can see some
tendencies. But that alone doesn't make up a new formula as I have
imagined. But I'm open to any other idea as long as there is
something envolved that touches the field of biology (and that's big,
believe me).
 I think it is now clearer what kind of idea I've got.

I am very grateful for this type of presentation. I have not enough grasp of
the nomenclature yet to feel confident that i understood the questions, but am
following along hoping that the solutions will clarify all O┐O. Any reply at
this point would be a guess.

Especially since i haven't had time yet to learn to load the list posts and
would like to learn to approach the things i'm finding in fractint with an
understanding of how to tweak them or even design for a particular area be
imaged.  Long road ahead:▐.

Thanks for everyone's patience with new folks and for all the tutorial
thingies!!
Still looking to post an image (fingers crossed) and emerge from lurkdom.

Date: 20 Mar 1998 09:34:17 -0700


If you want a newsgroup, you can always use sci.fractals -- which I
helped create and have since abandoned.  Why have I abandoned it?
Because usenet is (now) a classic example of the "tragedy of the
commons".  Since noone really owns usenet or controls it or issues
rules for it, it has been abused and "overgrazed".

If you attempt to gain useful information from usenet now, you will
have to wade through many spam messages to get what you're looking
for.  Even worse, if you decide to post to usenet you will forever more
get gobs of spam at that email address.  Even moderation won't fix the
problem of e-mail spam generated by extracting email addresses from
usenet posts.

To avoid spam, what everyone has done is started fudging their email
addresses in their usenet posts.  So now when someone asks a question
and you know the answer, you can't easily reply to the sender of the
message in private because they've farbled their reply address to avoid
spam.

The end result is that everyone I know who previously used usenet to
exchange knowledge, experience and information now restricts themselves
to local newsgroups or mailing lists like this one.  (I read the
newsgroups at my ISP and the support newsgroups carried by my compiler
vendor, but nothing more.)  Many new people joining the net can grok a
mailing list, but usenet is completely a mystery to them.

I know I've gotten much more information from these fractal mailing
lists that have been created in the past year or so than I ever got
from reading or posting to sci.fractals.

Pete,

I suspect that the limit is one of those infinity of numbers that have no
"nice" representation.  The number that Jay and I both found (-1.78...)
seems to be a good start.  Another problem is that the limit is not well
defined.  That is, we (humans) understand the process of zooming in
repeatedly, but mathematically (I think) there should be one point at the
end of all this zooming.  Where would this point be?  For example, there
is a well-defined limit at the Feigenbaum point, the limit of all the
period-doubling cascades.  I'm not sure what the corresponding point is in
your question.

Subject: (fractint) A linear color palette in Fractint
Date: 20 Mar 1998 15:51:27 -0500


The other day I got a bit frustrated with my clumsy attempts to craft some
changes to a color map using the Fractint color palette editor. Trying to
position a color band under the 'F' command was causing the frustration
since I was trying to get it positioned near one of the 'folds' in the
16x16 color-matrix.

"It would be a darn sight easier if this palette was linear rather than
boxed and folded like this!" is a sanitized version of the thoughts that
were running through my head when it popped into my mind that a 'fractal'
constructed as a flat, inclined plane would simulate a linear palette. So
why not create a Fractint formula for a flat, inclined plane? Simple, no?

OK, so I'm not a Fractint formula expert, but I told myself I could use the
practice. It ought to be something like:

palette-psuedo-code  {
  Initialize K to some linear function of real(pixel) :
  Iterate K = K - some delta
  Until K < some constant
}

So I hacked and hacked and finally here's what worked: (I have a
1024x768x256 monitor)

palette           {
  reset=1960 type=formula formulafile=fractint.frm formulaname=palette
  center-mag=-0.858435/-10.7688/1.859669 params=200/0/1/0/100000/0
  passes=1 float=y maxiter=500
  }

frm:palette {
  K = real(p1)*real(pixel):
  K = real(K)-real(p2)
  |K| < real(p3)
}

Would a Fractint formula expert care to answer a couple of questions? I'd
appreciate any advice on how you would have attacked this 'problem'. I sure
discovered that I don't have a 'feel' for fractint formulas.


Why did I require such large values for P1 and P3?
Why did I have to go to 500 maxiter?
Do I really need all those real() function calls?
Why didn't real(K) < real(p3) work when I tried it? Why did I have to use
the absolute value of K instead?
Could I have calculated the parameters and center-mag values from scratch
just knowing my monitor resolution? (I think this is the real question I
have. If I really understood formulas I think I could do this, but I
haven't a clue.)


(This approach to editing a color map using a linear palette is sort of
helpful
even though it's sort of an extra step to have to load the linear-plane
fractal gif to edit the color map.)

Thanks, any comments would be appreciated.

Bill...

I'm not really sure where your frustrations with the colormap editor
are......but I know I can whap out a new color map in about 10 mins on a
good day and I'm a computer dolt. I seriously suggest you take a look at
Linda Allison's lesson on the colormap editor. She made it very easy for me
to understand. I don't know from this "F" command that is frustrating you
and probably don't want to learn. Try Linda's approach....

http://wizzle.simplenet.com/linda/lindas_lessons.htm

will get you to her wonderful explanations about the color map editor.

Best wishes for happy fractaling

Date: 20 Mar 1998 17:39:35 -0500

Well...  after a bit of thinking, I tried zooming out one level, and that
worked.  As a matter of fact, it also jumped out of arbitrary position into
regular float mode.  It may have had something to do with the problem I had
with the julia set before.

Subject: (fractint) Colormaps Ahoy
Date: 20 Mar 1998 14:54:29 -0800

I've now sorted all of the colormap submittals to date into categories
....after pruning we have:

1. 1,2,3 maps = 21
2. Blacks = 8
3. Jewels = 14
4. Mid to long gradients = 43
5. Short gradients = 8
6. Specialty = 6
7. Stripes = 25

Total 120 maps

Question......fractint currently comes with 27 maps, including the default
map. I suggested we bundle about 80 or so maps with the new version of
Fractint. For those of us running Winders even a 4k map takes up 20k space
(I believe) due to the way Windoze partitions a 2gig disk. That means 80
maps take up 1.6 megs of space.  Is that acceptable? Folks can always toss
maps to save space.

Assuming 80 or so maps are OK .....I'll start work on a run-off in the 123,
mid-long gradients and stripes categories. How do people want to see the
maps?? I can bundle the whole shebang up or by category (which I think is
more useful).

The maps submitted have been great!!! I've enjoyed myself immensely looking
at all the wonderful variations. Thank you all so much.

Well, I think I heard someone say something to the affect of that the
closest minibrot is one thirty-second of the size of the current one.  So,
if the center of the starting minibrot is exactly -1.75 and the center of
the next is exacly -1.75 + -1.75/32, then the next after that should be
-1.75 + -1.75/32^2 etc. etc.

Jeez,  on a 2gig disk, how can 1.6megs NOT be acceptable? :)
And besides, MS-DOS partitions a 2gig disk the same way :)

Good idea and you can do it in very little space as one file containing
only pars required to create the images. The color part can be copied
out into any other par we need it for.

Example fragment.

colors=000<62>w00002<61>0w0404<61>00w666<61>www000000000

As an extreme limit, 80 of these is only a few k.

Subject: (fractint) Three-way rendering formula
Date: 20 Mar 1998 18:13:33 -0600 (CST)

comment (
Of all the rendering methods I've posted to this list, the one
below is perhaps one of the most useful and versatile, even
though it's very simple compared to many of the others.  I've
used this method on hundreds of images in the two years since
I developed it.  It will work well with any equations that normally
have |z| < something as the bailout test.

I call this my three-way rendering method because the same image
can have three very different 3D effects depending on the colormap.

To see what I mean, first run the par called 3waymnd1.  You'll see
an overall image of the classic Mandelbrot set except that the
banding around the set has a smooth rounded appearance.  Save the
file if you want to.  With the image still on the screen, press
the @ key and select cmap1.  The banding around the Mandelbrot set
will change to have a folded look.  Then press the @ key again and
select cmap2.  The banding now narrows into strands and you can
see the background color through them.  Pressing the @ key again
and selecting cmap3 brings back the original image.

These effects are more dramatic when used on the image created
from running the par called 3waymnd2.

I'm hoping you're finding this stuff useful - are you?

The Map bundling idea sounds OK to me.  BTW you can re-partiton your
HDD so it won'y waste as much space.  Mine only uses 16k blocks versus
the 32k blocks it used to use.  The down side is you have to reformat
and if ya goof there is no going back unless you have a backup (I have
learned to love my Ditto 2GB external a helluva lot) but if you resize
your partition[s] you can get back a ton O' space.  After all you're
not giving up any space just re-distributing it.

Oh well that's my no sense worth.

This is not quite right. You do not have to reformat the hard drive to
achieve this goal. There are commercial packages that will repartition
your hard drive quickly without the need to reformat nor to back up
everything onto floppies or whatever).
  I have used Partition Magic to partition my hardrive ( see
http://www.powerquest.com/product/pm/index.html ) and there are probably
other software developers that provide similar products.

Now start Fractint fresh and point to this par file, select colors6 and run

it. You will get everything as defaults except the colors, inside, maxiter
and cyclerange. You should see the Mandelbrot set (the default). Zoom
into seahorse valley.  I set the maxiter so you could do the next step.
Press E to edit the colors, see how nice they are  :-)  Note the color in
cell 253.  It is for Dr. J, he is loosing his tan.

Now cycle the colors, OK  stop cycling and edit the colors - press E.
You messed them up?

No! Not completely.  See the colors are cycled in the range which
leaves color number 253 unchanged so it is still usable as the inside
color.  This is the kind of info we need in a color map. It is not enough
to have a .map file for some applications.  (These colors are for Dr. J's
Jello fractals he is tangling with lately.)

The neat thing is (someone pointed this out to this list last year) that
you can have a picture in progress and load just new colors only
using this method.  Go ahead, load colors8 and watch Fractint
recompute the same fractal with the new colors.

And all the colors are get-at-able with long names from one file,
for someone making a new image.  Once the image is created, the
'B' save procedure will put all this in the new par.

Hmm... I remember from some time ago that there is a program written for
the HP48 calculator that would solve funky numbers like that for thier
fractional equivalent. It even inluded such numbers like square roots.
perhaps that is how he did it....

It is verified: Thereare Herman rings in Nuclear! Moreover, there are
Herman rings of a type I have not seen before, where the ring
center...well... I'll let you see for yourself. First two new formula
files, which draw Julia sets of Nuclear in 4 color ranges basedon not only
convergence to infinity but also any finite attractors. Then more PAR

ring and zoom of an intriguing structure...

Subject: (fractint) Doing lengthy computations once per image in Fractint 19.6
Date: 21 Mar 1998 03:33:40 -0500 (EST)


Many have lamented the lack of a "per-image" initialization in Fractint
formula files. Lament no more. It can be done! Here's how:

To do something simple only once per image:

foo {
  stuff
  IF(!notfirstpixel)
    slow_stuff_not_pix_dependent
    notfirstpixel=1
  ENDIF
  stuff
  :
  stuff
}

If you want to do something looping, such as iterating some critical
points to find finite attractors (as done in my newest Nuclear Julia
formulas above):

foo {
  stuff
  m=maxit
  m2=maxit/2
  IF(notfirstpixel)
    m2=0
  ELSE
    initialize some variables where results will go
    (za, zb, zc, qqa, qqb, and qqc in the Nuclear_Jul_Col's)
  ENDIF
  stuff
  iter=0
  notfirstpixel=1
  :
  IF(iter<m2)
    Newton's method, iterate some critical points, you name it
    Won't execute when m2=0 when notfirstpixel is true
  ELSE
    Normal iteration
    (Note: First pixel will only get 1/2 normal iterations. Should not be a
    problem.)
  ENDIF
  iter=iter+1
  stuff
}

Subject: (fractint) How I found it out
Date: 21 Mar 1998 03:41:05 -0500 (EST)


I have discovered that Fractint zeros all the formula variables once *per
image* but keeps them from pixel to pixel. How I did it: First I had, in
making a goof (missing a something=0 in an initializer ina formula)
observed that Fractint remembered a formula variable from one pixel to
another. (A counter had kept counting pixel by pixel, resulting in a
striped image!) I realized I could speed up my first attempt at the
Nuclear_Jul_Col if it turned out to zero them at the start of the image.
(It originally did the SAME ~2000 iterations of the 3 critical points
every pixel! This was slow and ledto hour long calctimes on "simple" Julia
sets. Ouch.) So I did this:

fuddle {
  IF(adq==0)
    adq=3
  ELSE
    adq=14
  ENDIF
  :
  z=adq-8
  done=1
  done==0
}

If adq was zero, it would become 3. Then z would be set on first iteration
to 3 - 8, and the loop would immediately exit, yielding a cyan pixel (using
the default color map and outside=real). If instead adq was nonzero, it would
go to 14, yielding a yellow pixel. I ran this with outside=real, logmap=0,
maxiter>255, and passes=1, and got a single blue pixel in the upper left
corner of an otherwise yellow screen, thus demonstrating 2 of the 3 things
I was hoping to verify: that variables are set to zero sometime before use,
and that they are definitely kept unchanged from the end of one
pixel to the start of the next. They were zeroed at most once per image.
But maybe they were only zeroed less often, e.g. per use of the formula?
That would be no good.
I then upped maxiter  (specifically from 2000 to 6000) to force a
regeneration of the image. Same deal, thus showing that the variable is
indeed zeroed again at the start of a new image, not only zeroed for one
run of the formula or for one run of the 'z' parameters or for one run of
Fractint.

It works.

Heh. :)
That's coloring by all critical points, just to get neat effects like
that. It superimposes the pictures for all 3 critical points. The red buds
are where one of them is going to finite attractors and is determining
them; the orange Julia inside is where one of the other 2 is being sucked
into the attractor picked by the first. (Elsewhere it was going to infinity.)
Note that the Julia set fits with the bud's period and location. This neat
effect occurs with all the multicolored Nuke Mandelbrot formulas, as well
asthe tricolor and 4color formulas posted ages ago.

It's supposed to do that... the comments should make that clear; the
Mandel ones without a specific critical point use all 3 to make a "triple
exposure" picture using color ranges. The comments say to use
outside=real; outside=summ will work identically (since the z value
emitted has imaginary component 0). Best results without using a logmap,
but there's an ersatz logmap builtin with 2 real parameters, which affect
the "compressed" you usually use logmap=2 to achieve, and the rate of
decline (not an option using the normal logmap!). It uses not a log but an
nth-root, like the square root alternative logmap, but using any n. Bigger
n means more colors for lower iterations. n smaller than 1 means colors
pushed toward higher iterations. Either way all iterations are used.

The new Nuclear_J_ColLog uses a logmap similar if not equal to the builtin
one, with no compression. (No tweaks because no spare parameters!)

Heck, then why not keep all 120? ;-)

Better yet: Put them in a PAR that renders a full-on Mandelbrot with each
map in turn. Then supply with Fractint a few maps already, the PAR, and a
maps.key .key file (you do know about the autokey feature, don't you?
;-)) that draws them one at a time and saves the maps, and cycles them for
effect. The key file, even with map names and stuff, won't be big either.

Hi,
Has anyone run Fractint w/a Diamond Permedia II video card. I am about to
purchase a new computer that comes with that and wld be interested if I wld
have a problem with Fractint w/ that. The salesperson has never heard of
Fractint. Also, is a Sony 17'' monitor w/ .25 dot pitch that runs at
1600x1200 sufficient for viewing fractals. Pls answer me personally, so as
not to clog up the list, as I have just done.
Thank you

Heh.. I guess you should have bought the gx. I have an sx, and I went and
put a 128 card in it. (160 total) I've yet to run out of room.

Subject: (fractint) formula
Date: 21 Mar 1998 22:07:28 -0800

I've been learning to write formulas for a while now, randomly
changing things,  having fun at it but have not come up with
anything particularly interesting- I guess this is not too surprising-
You drop a watch on the floor and... most of the times it's worse!
          There's been talk of a contest based on coloring methods
and I was looking at a fractal in "The Science of Fractal Images"
with a very simple formula but a different coloring method.  (page 160
if you have it).    This is waaayyy past my level of knowledge of this
but I was trying to write a formula and found it was worthwhile for the
basics of it- like is the initialization right and what is the bailout
here and how does Fractint assign a color really, aside from hitting
the "x" screen  and hitting "iter"....
     So can anyone put this into a fractint formula?  It's a cool
picture.  (Sorry about the length of this.)
     " ...the Julia set of 1/e*e^x (in white) approximated by points
that escape to infinity according to the following criteria: A point
z(0) is colored white if the orbit of z(0) contains a point z(k) with
real part Re z(k) greater than 50 within the first 25 iterates and if
cos (Im z(k)) >= 0.0 (i.e. the next iterate z(k+1) will be very
large...."  (from The Science of Fractal Images " by Peitgen et.al.)
         This is what I tried:
    {z=pixel
        IF (real(z)>50) && (cos(imag(z))>=0)
      ???what next
Would the k =25 iterates be the bailout value?
How do you get it to assign a color?
Thanks in advance to anyone who read this far.

Subject: (fractint) HP-48G fun!  (aka Sqrt(3) in the Mset)
Date: 22 Mar 1998 03:02:49 -0500

Well, my Calc teacher got a massive grant from HP (I think it was them, or
maybe it was the school board.. i dunno) and got about a hundred 48g's and
she lends them out to the students in her classes who want/need them.  So,
naturally, I borrowed one, after I saw how nifty they really are.  Actually,
I wrote a fractal renderer on it, in RPL, since I didn't have a clue about
its assembly language, let alone have the time to figure it out.  It was
pretty cool.  I built in external formula capability, and I was working on
adding a zoomer, when I realized, hmm, is it really worth paying for a new
set of batteries every other week just to have something to do in school?
(sounds like  ti-85 zshell tetris, huh? <g> )  And besides, (needless to
say) it was slower than a Yugo, and my ram was running short, too (hehe...),
which slowed it down, a lot.  I think the HP uses some kind of paging mode
or something, so it can use cheap ram for storage, and good ram for
calculations... My friend demonstrated this by repetitively copying a number
onto the stack... about 2 bazillion times.  It got to the point where it
took about 10 seconds just to begin reacting to a key-press.  Anyways, I
thought a fractal renderer would be cool, but I didn't know they were
available anywhere.  How much I've learned since... :)  Of course, since
then, I've done more with fractint than I could've in 10e(10e5) years with
the hp, and in 1024x768 resolution and 256 colors!       [LOL :) ]

I enjoyed the formula and images, but I made a change to the colors to
be more appropriate for last Tuesday's Holiday festivities.  They are
attached as MAP files.

Am I supposed to replace a color map and if so which one?  I've never
cracked open the maps all that much, damn they're huge.  BTW do you
actually "type" this stuff in by hand?  If so you must go through
<TAB> keys quite quickly.


Before anyone says anything know this, I don't program, I don't hack.
If I can't run it straight off the shelf I don't run it.  That's not
to say I don't use Spreadsheets and Wordprocessors, I mean I don't
re-write programs from the inside-out nor do I alter add-ins.  PARS,
FRMS and MAPS are add-ins.  I run 'em don't hack 'em.  I just need to
know which file[s] do I replace, if any, in order to use the map
originally sent in this message.

I don't mean to sound curt but when I get more verbose I digress,
unfortunately I'm no good at balancing this out, sorry to sound this
way I honestly don't mean to.

Thanks!  I'll give them a try.

I'm going to be offline for a while.  My monitor died and I'm using
a borrowed one that I have to return in a few minutes.

Hi Kathy,

  The coloring method is: inside=3Dblack, outside=3Dwhite.

  The following formula doesn't give exactly the same image but it's
probably due to the way Fractint handles large values of z.

Sorry folks for the "long" email.  I forgot that the MAP files would not
be "clickable" attachments (because of being straight ASCII text).  I'll
just save the COLORS in the PAR next time before posting.

There are a couple of ways of supplying predefined colors to FractInt.
In the PAR, there is a parameter known as COLORS which usually looks
like this:
     colors=000<7>000000200<29>zKU<30>211000000<14>000010030<29>\
     0z0<30>020000000<14>000110330<29>zz0<30>220000000<21>000

The other method is to create a palette MAP file that is read in by
FractInt in the same manner that PAR and FRM files are accessed.  This
is the method I use most often.  (An excellant utility for doing this is
Ron E. Barnett's MakeMAP program.)  These color-maps are ASCII text
files set up as a series of RGB triplet values (one triplet per line,
encoded as the red, green, and blue [RGB] components of the color).

When you are running FractInt, there are various commands that may be
given.  You can save and restore color palettes for use with any image.
To load a palette onto an existing image, use the [L] command in
color-cycling [C] or palette-editing [E] mode.  To save a palette, use
the [S] command in those modes.  You can also just use the [G] command
to allow you to enter the following:
     MAP=filename
where the above "filename" is an existing MAP file either in it's own
directory or in the FractInt directory.  Your SSTOOLS.INI could point to
a default directory and file as follows:
     MAP=F:\Fracta~2\Fractint\Ver_19_6\Map\volcano.map

If you wish to try out the MAPs that I regretably sent out as
attachments, then save just the data from each one as a seperate file
with the extension of MAP.  Then follow the above notes.  Further
information may be obtained from some of the following:
     FRACTINT.DOC
     http://spanky.triumf.ca/www/fractint/palette_maps.html
     http://spanky.triumf.ca/www/fractint/commands.html#cycling_anchor
     http://spanky.triumf.ca/www/fractint/commands.html#palette_anchor
     Hit [F1] while running FractInt and look for either color-cycling
         or palette-editing.

P.N.L.

Subject: (fractint) Smaller Image Sizes for Fractals....
Date: 22 Mar 1998 16:01:23 -0600

.

The Windows version of ImageVice (from low-cost software champion BoxTop
Software) is soon to hit the streets.  ImageVice is a tool for Web and
multimedia designers that makes Web pages load up to three times faster
and allows the designer to store up to three times the content in the
same space.  BoxTop Software now has a fully functional and nonexpiring
demo of ImageVice 1.1 at its Web site:

       http://www.boxtopsoft.com/

This program will work its magic with ANY image, just as the Macintosh
version has done for some months now.  ImageVice can make GIF, PICT, BMP
and PNG (the most popular multimedia formats) images as much as 70
percent smaller.

ImageVice works as a file filter that is plug-in compatible with Adobe
Photoshop 3.0 or greater and other host applications supporting the 3.0
Photoshop filter plug-in API.  It's available for Macintosh, Windows 95,
and NT.

Fred Showker, editor of DT&G Magazine, says, "This new multimedia color
reduction and compression tool breaks all records for the smallest GIF,
PNG, PICT and BMP files -- we're talking over 75 percent reduction
here.  In our testing we're finding it even better than JPEG
compression!"

Just a reminder. This list doesn't let you post messages if the
return address doesn't match the address you are subscribed under.
This is to prevent spammers from blasting the list. So far it has
worked well; we have avoided spam.

Unfortunately this can be a bit of an annoyance to list users, since
you can't post from other accounts or place NO_SPAM in your return
address.

Here's some thoughts on collecting color maps for Fractint...

Save them as par files then delete everything except the title/info plus the
"colors=" statement.

This is easy to do and has several advantages over the more usual .map method:
1. You can use long filenames
2. Include descriptions, dates, author and other info.
3. Whole collections can be bundled into one file to maintain themes, favourite
artists etc.
4. The files take up much less storage space (the attached example occupies
1.07K, compared with 3 x 3.25K for the same (less?) info in .map format)

To use this type of "map" just load it as a par file (using the <2> or <@>
keys), choose the map you want, and it will replace the colors in whatever image
you currently have on screen.

Greetings,

Sometimes there can be so many irons in the fire, so to speak, that time
for attempts at original material simply is not there. Which is one reason
for collecting gifs, pars, and color maps. A slight modification here,
another there, and a nice looking image comes up...

The below are two recent combinations:

Please note the other (perhaps new) ideas in my post. There are
certain color maps which are valid over a limited color cycle range
or have other limitations. These can be included as I did, and when
they load, they don't mess-up the rest of the image parameters.
But the image does recompute. If it is only the colors= parameter
loading, the image does not recompute.

Comments should be included identifying the author and date.
Also other remarks can communicate recommendations.

These additional parameters are especially useful for Paul Carlson's,
Kerry Mitchell's and several others on this list.

Jay

Last night I enjoyed myself playing with one of the nuclear FRM's.
I hope you may find some merit in the results.

O.K., I may have missed some of the discussion on the Fractint mailing list
about my questions on ImageVice, so forgive me if this is "deja vu".

Is ImageVice a lossy, or a lossless format?  If lossless (or it has a lossless
setting), how do file sizes compare with PNG, etc.?

I was cruising through the Newsbytes web site (www.newsbytes.com) this
morning - it's a pretty good place to scan for computer industry related
news items - and found a reference in its "Internet News" section to a
fractals area.

I took a quick peek at it, and it looks fairly interesting. Check out
http://www.cln.org/themes/fractals.html (CLN stands for "Community Learning
Network", and its fractals theme page is mostly about learning about
fractals).

It looks like there's lots of interesting stuff in there.

The FBI and Secret Service are buying off all the people who just a little more
about fractals than us, for work on a top secret mission, codenamed Yellow
Submarine, which, when completed, will accomplish many amazing things, including
the apparently impossible task of teaching nine-year-olds reasonable social
skills.  Nah, that could never happen.  :-)

Sorry, I don't do pars in payment for off-topic posts... trust me, it's better

In the age of SPAM, public newsgroups are very high-maintenence. Keeping
a newsgroup from drowning in spam requries a couple of things-

people on the group who go after spammers pretty vigorously;
enough traffic that the spam gets drowned out anyhow;
and a willingness on the part of posters to use hidden reply-to names,
dummy accounts, filters and so on to avoid spam mail...

sci.fractals was probably never quite busy enough to do this...

Subject: (fractint) Batch mode made easier...  Yeah right :)
Date: 24 Mar 1998 19:02:38 -0500

This is a multi-part message in MIME format.

------=_NextPart_000_0007_01BD5757.69DB6880
Content-Type: text/plain;
    charset="iso-8859-1"
Content-Transfer-Encoding: 7bit

I wrote these batch files to make batchmode easier to use.  I thought it'd
be helpful...  The pair runs through all the images in one directory,
renders them, and moves the completed ones to another directory.  I have 2
directories on my computer, one for images I want rendered immediately, and
one for images I want done later... like high-digit arbitrary precision
images... :)  However, before you use it, you'll (probably) need to change
the directory names, to match yours, and you'll also need to create a file
with an ini extension, which creates the parameters you want to use, such as
video mode.  To use them, run "runbatch.bat <filename>" where <filename> is
the first eight characters of the ini file's name.  This file then runs
batch.bat on the images in
"d:\fractint\images" and moves them to "d:\fractint\images\complete" on
completion.  (You'll probably need to change these.)  It then runs fractint
on "d:\fractint\images\later" and saves them to the same directory.  Of
course, prior to running this, you'll need to begin rendering the images and
then save them.  It also saves whatever progress or errors it makes in
"batch.log".  To quit the batch file, you can press any key during a render,
after which it says "Press ctrl-c to quit or any other key to continue",
then press ctrl-c (duh.. :) ) and it dumps you to a dos prompt.  If you run
this from a dos-mode pif in windows 95, pressing ctrl-c bypasses the rest of
autoexec.bat, so you'll need to reboot and hit escape when win95 tells you.
I hope you find this useful! Since they weren't too big, i attached them to
this mail...

It seems some dolt crossposted a thread in somewhere (alt.flame?) to
sci.fractals and dozens of others, and people are following up, flaming
each other, and cluelessly not changing the followups-to. :P

I have complained to a number of their postmasters.

Subject: (fractint) Flexball Mandelbrot Formula
Date: 25 Mar 1998 21:03:20 -0600 (CST)

comment {
I call this rendering method my "flexball" method because it's
a modification of my "tangent ball" method (which consists of
strings of balls tangent to each other).  Flex balls are connected
to the "balls" on either side of them along a line, and the balls
can appear very compressed or very elongated, whereas the tangent
balls usually remain more or less round.  In this formula I use
the flexball method on the standard Mandelbrot equation; however,
it works nicely with many differnt equations including Newton's
method fractals.

This is one of my more complicated rendering methods, using a
ring orbit trap and setting the color range depending on
which 1/8 of the ring the point falls in.  The complicated
part is the computation of color index within a range, to make
the flexballs appear rounded without repeating colors within them.

I chose these pars to give you an idea of the different effects
possible with the flexball rendering method.

Subject: (fractint) Misc

Friends,

  A few thoughts and suggestions.

> 051597-002-m1-m2-m3 {

One reason this formula was causing a problem is that the name exceeds the
limit of 18 characters. The next release of fractint will report an error
if a formula name exceeds 18 characters, but for now people just need to be
aware of the limit and observe it.

> qq=10^-2

A couple of Paul's "nuclear" formulas contain statements where a negative
exponent is used. The formula parser has trouble with this, because the
operator "^" and the unary operator "-" (negation) have the same
precedence, and the associativity of operators with the same precedence is
always left to right. To assure that the formula will work as intended, the
exponent must be parenthesized, i.e. qq=10^(-2). There is no warning about
this in the current release; the next release will report an
unparenthesized negative exponent as an error.

Re the naming of par entries:

   1. The name ends with the first blank space, "(", or "{" encountered.
Thus

        mypar one {
        mypar two {
        mypar three {

are all treated as having the same name "mypar".

   2. Users of Michael Peters' utility "partobat" are appreciative of
artists who use image names of 8 characters or less, since this fits with
Mike's method of naming the .gif files produced by a run of partobat. This
is especially true when there is a series of par images with the same
initial characters and a numerical suffix, (mypar1, mypar2, mypar3 etc.) If
the numerical suffix appears after the eighth character of the entry name,
partobat uses its own numerical suffix system to differentiate the .gif
files, and it is often difficult for the user to then match the .gif file
with the par entry which produced it.

Regards,

George Martin

I received an email today that stated the following:

It went on from there to say they had used some of the images from my

"financially independant and not in need of the money".  But ended the
email with the following:

My questions to all those in Fractal-Land, what would YOU do in this
situation??  Is a needlework product of one's fractal image infringement
of ownership rights, or is it a seperate interpreted image??  Should
there be equitable compensation for the use of such image/s, or would
just the acknowledgement of the originator be sufficient??

Any and all comments welcome (on or off the discussion list).

Later,
P.N.L.

     Why do most folks hate cynics so much?
       Because we're almost always right.

Paul,

In my opinion, you have a valid case for copyright infringment.  There's
nothing gray about copyrighting fractal images.  The final needlework
piece is a separate, individually-copyrightable work, but it's existance
depends on your original work.  To me, that is clear.

However, the next question is what to do now.  I think that I would see if
this person is worth dealing with.  If so, I would push for a business
relationship wherein you either sell them a flat license or get royalties
for the use of the image.  Or, take it directly to the needlework company
and identify yourself as the copyright holder of the image, and deal with
them.  In any case, you deserve to be compensated for the use of your
image, should you desire compensation.  At the very least, you deserve to
have your wishes respected as to how the image is used.

Push for compensation or demand that they stop using your work.
Kerry

Subject: (fractint) Nuclear MeltDown Redux (Pars)
Date: 26 Mar 1998 20:40:20 -0800

Here are some pars. Just saw a copyright discussion starting. So for the
record, I have used the tworain, volcano, and Paul Lee's Irish_01 maps for
these. Don't know whose the first two are -- they just appeared  after I
dumped fracxtra into my Fractint directory. Seeing these requires some of
Paul Derbyshire's nuclear formulas. One of them, my tribute to Pink
Floyd, is on abpf. Seriously, tho, if  not using maps is OK, pls yell
at me.

And if the images are really bad, then I take full credit. If (unlikely)
any are good, I give all the credit to the people who did the maps and
wrote the formulas, and programmed Fractint. Pls don't sue me: I only own a
banjo, a computer, and  a lot of books.

Fractal Needlework, tho, hmm. Paul, if that turns out to be the next
hula-hoop, you might be able to make a fortune  there :)

Recently, I have had some nibbles from two different needlework companies
interested in buying my designs for sale as kits and/or pattern leaflets in
the public domain.

At a minimum, I feel obligated to give credit to the creator of the
original image source and, at worst, realize you may wish to prohibit me
from proceeding
altogether. Please let me know how you feel about my use of your images to
create products for sale.  I realize the copywriting of fractal images is a
grey area.

I do not think there is any grey area in here at all. We have covered this
before; personally, for personal usage I would have no objection, but as I
learned from reading up on the copyright laws, even that can be considered
an infringement. _For sale_ is an entirely different matter. Consider the
reaction  of, say, the Walt Disney company if someone were to start
needleworking images of Mickey and selling them...Or likewise, the Boy
Scouts, or Coca Cola, and so on...but this should be enough said.

Run, do not walk, to that needlework company, and advise them of your
ownership. And advise the person that this would be better settled with a
three way written contract (if there is such a thing) between you, the
needlework company, and her/him.

I fully agree with all of Kerry's points. A copyright is good for
prohibiting any sort of use of the image, no matter what the format the
image is converted to (movies, needlework, painting, etc.). A royalty from
the needlework company would seem the most workable arrangement.
Establishing the date of your copyright is easy and can be based on the
file date of the image.

Hi, Ray!  You asked:

(snipped copyright info)
>Does this have a bearing on the subject?

Not really.  You've missed out on the Great Copyright Debates on both the
Fractint mailing list and the Fractal-Art mailing list.  The bottom line is
that an image is copyrighted at the time of creation, regardless of whether
the artist does or does not register the image as copyrighted.  All rights
to use of the image are held by the creator of the image.

The Stone Soup Group has very generously made Fractint available as
freeware, for which we are all grateful.  (Deep bow to Tim, here.)  But
that doesn't have any impact on whether the artist does or does not freely
grant rights to his or her images that are generated in Fractint (or any
other freeware program).

You can probably get copies of the original debates from the archives of
either mailing list if you want to wade through them.

I made some fractal needlework once. I wrote an Amiga program to generate
fractals; and later I added a feature to make a small image and then blow
the pixels up to gridded squares that can be easily used as a pattern.

to a different fractint .map file.

Be careful here.  The copyright is clearly yours, but remember that the needle
pointer is both a fractal enthusiast, and consciences enough to ask Paul for
permission.  They even closed with:
> "I feel I must defer to you as the 'owner' and accept your wishes in this
matter."
IOW, try not to offend or discourage someone who seems to be doing something
creative and original with fractals.

Hold on a minute, what about the Fractint authors?  Surely they deserve
something too?

Lots of people have created Fractint and contributed new pars and formulas,
allowing them to be distributed free of charge, because that way, the
community as a whole benefits, and people can freely improve upon others'
work.

Whatever fractals you did generate, I am sure you wouldn't have been able
to without relying on code, formula files, colour maps, and inspiration
provided by others.  Of course you have a right to slap a restrictive
"licence" on your images if you want to, but perhaps you should consider
giving back your work free of charge, as others have before you.

Strictly speaking, they don't deserve anything *in the context of this
thread*.  (In general, they of course deserve our thanks, praise, and
spare change!)  Images that are produced with a tool are the property of
the artist, not the toolmaker.  Just like Adobe can't claim copyright on
anything done with Photoshop, or Grumbacher can't claim copyright on
anything painted with one of their brushes.  Tim et al have repeated made
clear the difference between Fractint, which is copyrighted by the Stone
Soupers, and the images produced using Fractint, which are owned by the
individual artists.  Otherwise, Kodak, Fuji, and Agfa would own all
photography, Microsoft would own all poetry written using Word, etc.

At 08:50 AM 3/27/98 -0600, you wrote:

[Run, do not walk, to that needlework company, and advise them of your

{{Be careful here.  The copyright is clearly yours, but remember that the

"I feel I must defer to you as the 'owner' and accept your wishes in this
matter."
IOW, try not to offend or discourage someone who seems to be doing something
creative and original with fractals.}}

I have to disagree; you may want to re-read what I wrote.
I have no objection to _personal_ usage of my fractals (Others feel
differently). However, when it comes to selling them, that is an entirely
different matter and enters a completely new area. Re-read the following
portions of my previous post:

"... We have covered this before; personally, for personal usage I would
have no objection, but as I learned from reading up on the copyright laws,
even that can be considered an infringement. _For sale_ is an entirely
different matter. Consider the reaction  of, say, the Walt Disney company
if someone were to start needleworking images of Mickey and selling
them...Or likewise, the Boy
Scouts, or Coca Cola, and so on...but this should be enough said."

"... And advise the person that this would be better settled with a
three way written contract (if there is such a thing) between you, the
needlework company, and her/him."

IOW, when an individual begins selling patterns of someone elses' original
art work, regardless of being an enthusiast, it has become a business
arrangement.
If someone wants to do something creative and original with one of my
tinkerings, such as making personalized stationery for private/personal
use, fine. If that someone wants to sell it, I want a piece of the profits.
And if a company decides to start selling one of my tinkerings, that
company is going to pay me. (Now ask me if I expect that to happen...  :) )
With the real artists out there, this may become a good portion of their
possible income...

and re: another post:
>[about selling fractal-based needlework products]

{{Hold on a minute, what about the Fractint authors?  Surely they deserve
something too?}}

No. To quote from the docs:  "Fractint is freeware. The copyright is
retained by the Stone Soup Group." The program has/is being given away
free; the copyright belongs to the program itself, not what is created with
it. Consider a well known photographer, such as the late Ansel Adams (Name
correct?) Would Kodak be expected to be given a portion of the proceeds
from his extraordinary photographic artwork?

Besides, another quote from the docs: "Contribution policy: Don't want
money. Got money. Want admiration." (p.9)

Shame! Please do not post binaries to sci.fractals.  There are binary news
groups.
Read the sci.fractals FAQ.

The best approach is put your binaries on a web site such as Spanky. Then post
a reference.

It was never a high volume anyway.

People are abondoning usenet in droves because of spam problems --
either putting up with or filtering out posted spam, or dealing with
endless amounts of spam generated in one's mailbox as a result of
posting.  Consequently, people are abondoning usenet.  (I created
sci.fractals and I've abandoned it for that very reason.)  Plus a
number of mailing lists have sprung up over the past year or two and
generally new people to the 'net have an easier time dealing with
mailing lists than newsgroups.

It's still interesting to see that this makes the Nova derivation act
cubic. It seems that a cubic convergent method turns the roots into
critical points with multiplicity two...
Anyone know of methods with other convergence? (Quartic? Quintic?
Infinite?! Infinite would produce exponential-style Mandelbrots. One
Halley website did derive it from Taylor's formula of order 3, so maybe
if I took order 4...)

No, but there are a couple unixish freebie networked Mset renderers.
They are all lacking in features compared to fractint though.

Well maybe if you explained what an "RPM" is someone might be able to
answer your question.  You can download xfractint source code from

Date: 27 Mar 1998 17:04:30 -0800

since a recent suggestion to have a coloring methods contest met with a
pretty much deafening silence, well, then damn the colors, full speed
ahead, is anyone interested in an M-set deep-zoom contest? there cld be two
winners: deepest zoom into the M-set and freakiest shape found. while I
imagine most people wld use Fractint, I guess an interesting option wld be
to allow people to use the program of their choice. come to think of it:
what is the definition of the deepest zoom? freakiest, I guess is
self-explanatory

Rich,

 - Well maybe if you explained what an "RPM" is someone might be able to
 - answer your question.

RPM = Red Hat Package Manager, a method for distributing files to be
installed on UNIX systems.  RPM ships with Red Hat Linux, which you can buy
or download.  Generally I find it much easier to download and install an
RPM with pre-compiled binaries than to download, install, compile, and
troubleshoot source code. :)

Here's my deepest zoom par:

center-mag=0/0/1e1200

:-)

Seriously--I would suggest that a deep zoom contest be a "smallest midget"
contest in order to prevent such easy tricks like mine to weed through.

And how does one define "freakiest shape" anyway?  What is freaky?  What
is hip?  What's it all about, Alfie?  (insert other song cues here)

Sure... if the entries are due in about 10 years :-)

> there cld be two winners: deepest zoom into the M-set and freakiest shape found.

How about just "freakiest shape in the standard M-set at any zoom
level?"  Judging deep-zooms could take forever, unless entries are sent
as gifs.

It's a good idea in principle, but I'm concerned about the time
deep-zooms take.
I'd better start now. :-)

This has no bearing on the subject. That Fractint language just says,
we, the Stone Soup folks, claim a copyright on Fractint itself but
don't claim copyright for any new images you might create WITH
fractint.

The fractint program's legal language certainly does not mean that
fractal images made with fractint are not copyrightable. Most fractal
images are copyrightable by the artists.

    Things seem relatively normal at this end, though it's
difficult to tell where the bottleneck might be. They installed
a new powerhub here last week and there might be some teething

I've said it before so many times I'm sounding like a broken record.

The most recent revision of the copyright law says that EVERYTHING
ANYONE makes is instantly copyrighted the moment they make it,
including this mail message :).  It used to be that you had to
specifically claim copyright in order to obtain the benefits of
copyright.  Now everything is copyrighted the moment you create it.

Subject: (fractint) Mangled Newton Mset Formula
Date: 27 Mar 1998 22:17:39 -0600 (CST)

comment {
This formula "mangles" the normal Newton method by using the
normal Newton method equations, but uses a strange criteria
for bailout.  The formula checks for root convergence only
to prevent the background from going to maximum iterations.
The background color is set to color 252.

All of the pars have the same coordinates and colormap - the
difference in the images is due to the functions and parameters
used in the "mangling" process.

This image is actually pretty much the whole Mset which repeats

Thanx everyone for posting the Gravijul formula. I'm sure more people will
be posting it, so thanx in advance. I went to the Fractint archive....boy
was it overwhelming. Looking through all those messages is monotonous and
very time-consuming. Anyone kept a GOOD tab on JUST the posted formulas and

On a related note it'd be nice if the archive webpage had a feature to
search through the archive to locate the first/next digest with a
particular substring. A search on "gravijul" from the beginning would have
found the formula Lavondyss wanted.

Kerry,

FOTD 27-03-98 == freaky shape. (Who's Alfie? What's a smallest midget?)
Maybe we cld use Jim's generalized formula for the nascent (well, maybe)
deep-zoom contest? There cld be a third winner, too: most stuzzadelic
fractal found. And since I believe only four people have expressed interest,
that means we only have to find one more category.

For those not on the fractal-arts list, the formula is

frm:MandelbrotN {; Jim Muth
b=p1, z=p2, c=p3+pixel:
z=z^(b)+c,
|z| <= 16

Complete monthly collections of all the par files posted to the Fractint list
are available from my Fractal web site at:

http://ourworld.compuserve.com/homepages/Les_StClair/

You'll need to download the formula file too (it's on the same page as the
pars).

I plan to post the March collection (which is fast approaching 300 images!!) a
couple of days after month end.

I don't know about a formal contest, but I'd love to see some
explorations along these lines. Maybe an informal "can you top this"
would be fine rather than a contest

The point of Sylvie's protest that these images are boring and time
consuming may be that if the objective is to produce art, deep
zooming is not the way to go. But there are other reasons besides
creating art to make fractals. I'm personally curious about what is
to be found at higher magnifications. I don't want to see "boring"
images, but I'm not worried if they aren't beautiful and artistic if
they are intriguing and interesting!

There are some complications. It is easy to come up with images that
are self-similar to much shallower zooms, which defeats the purpose
(see the spanky.triumf.ca for a discussion of this.) Usually if you
are zooming in on a midgit, the image is not self-similar. I don't
have a proof of this, but I'm pretty sure it is true. The image
doesn't have to contain on obvious midgit, but the only reliable
method I know of avoiding being sucked into a "whirlpool of
self-similarity" is to follow a sequence of midgits. Once you have
arrived at the desired magnfication, you can explore near the
midgit without fear of getting an image that could have been
generated at a lower magnification.

If you need incentive, here's one. I incorporated a synchronous
orbit (SOI) algorithm into the developer version of Fractint last
fall, but haven't worked on it since. It uses long doubles, which
limits the magnification to 10^20 or so. It works OK, but at that
magnfication it is just starting to get going. I really should port
SOI to arbitrary precision to get rid of the precision limit. If I
thought there were a number of users doing serious deep zooming
explorations, and SOI would help them, I could decide to finish this
off.

For those who aren't familar with what I am talking about, the SOI
algorithm greatly speeds up deep zooms. Porting SOI should help deep
zoom explorations, but we won't know until we try.

Tim

Oh wow!!..Great idea Paul. That would help out a lot of fractal folks. It sorta
reminds me of the "find" option in Windows Explorer. An example would be
"gravi*.frm" or "gravi*.par" or even "gravi*.*" I dunno how hard substring options
would be to program into a search engine though let alone the search enging itself.
It's be great to have though.

Deep zooming would be very nice indeed. However, for those of us who do not
have the newer computers would have a heck of a time trying to render them.
I"m running 100Mhz and it takes forever for some deep-zoom fractals. Plus,
D/L'ing all those pars would be quite painful as well if you do not have
unlimited access such as myself. However, I can wait till the end of the
month and get everything from Les's page..^_^. Just a thought.

Tim,

With SOI, do I have to have a faster machine to render it faster or
would it just speed up the process altogether? If the latter, then I'd
love to see it. Wish you luck.

I have been playing around with another flexible formula, and have
encountered a problem.  This works fine for the z^2 case, but breaks
down; try p1=3, 4, etc. to see what I mean.

Another question/observation: the imaginary component of "bailout"
has no effect (not that I would expect any for a magnitude comparison) (?)

I like this idea very much.  There needs to be some artistic-ness involved to
keep the contest from just being a technology contest.... and yeah, images
should probably be sent as GIFs.  Other thoughts:  use a standard image
resolution and colormap?  For those who don't know, I've got a little hiccup of
a program called Deeper available at my website that does a good job of zooming

Ohhh please oh please oh please oh please oh pllllease!  Um, sorry.  I would
*really* like to have SOI in Fractint, though.  I've been mulling over adding
something I call Symmetry Recognition (SR) to my Deeper program (as well as a
number of other improvements), and knowing that Fractint was going to someday
relatively soon have SOI would probably prompt me to work on the SR thing.

On the other hand, I suppose if interest in exploring the depths of the Mset is
low, then there are probably other Fractint improvements that should be
higher-priority.  I have not gotten any feedback on how Deeper is working for
folks (or even if it is, or if anyone's even dl'ed it.)  But myself, I'd be very
psyched for SOI!!!

Standardizing colormaps is incompatible with  "artistic-ness." Otherwise I like the

I agree that a standard color map should not be required, however, if it IS
judged, lack of coloring skill should not be part of the judging; rather,
the chance/skill of finding a really cool spot to draw and submit should be
the criteria.

Mark:

I have run into the same problem with some of my formulas.
The following version runs a bit slower, but works the way
it should.  I have no idea why.


MandelMax2 { ; slightly altered by Jim M.
; probably been done before...
; defaults: p1 = (2,0) p2 = (0,0) p3 = (4,0)
   z = p2, c = pixel, a=p1:
   z = z^(a) + c
    |z| < p3

informal sounds great. i wld be willing to maintain the current deepest
zoom images on my geocities page and provide info, which I and hopefully
others, wld contribute, on why such and such an image is interesting, or
how Fractint does what it does and how it might do it better, sort of like
the Deep Zooming page at Spanky. if you think it's boring, that's cool,
don't do it. i don't see how this cld clog up the list; it takes a while to
generate these things, so i don't think there wld be that many pars posted
on, say, a given month, or whatever. or arguing over rules.

it cld be pretty simple i guess it wld be best to just use a standard M-set
formula, with no user-defined variables. besides looking for interesting
objects, if there was any interest, there cld be a sort of repository of
the current deepest zoom, the way the newest largest prime numbers are
announced every few months. we wld just need a rigourous definition of
deepest zoom, if guess. and one wld have to produce the image, so you
couldn't use Kerry's ruse of writing a par without having zoomed. no voting
or talking about how the contest is going.


you spend a week, or whatever, zooming and you just, as Tim said, post yr
can-you-top-this par. since most may not wish to reproduce a particular
zooming marathon experience in the privacy of their own home, you cld send
the gifs to me and i'll put 'em on the web page and post 'em to abpf, if
that is wanted, so anyone interested can look. i already get the SPAM, so i
don't have to worry about mangling my address. it might even generate a
little public interest and, who knows, spawn some practical application
(pace, G.H. Hardy).

i am much more interested in learning and seeing and exploring rather than
a contest per se. and hopefully the expert wld provide some tips. zooming
is fun.

is anyone else interested? then seeya in the M-set, i guess.

Synchronous orbits, when it works, can be more than an order of
magnitude faster than normal escape-time algorithms. It doesn't
depend on a fast machine. But if your machine is fast, AND you are
using synchronous orbits, then everything is faster still! SOI only
begins to be effective near the limit of zooming of double precision
numbers (2^15 or so).

I am not aware of an implementation of SOI for arbitrary precision.
There are some good ones for 64 or 80 bit doubles. My current
implementation is for 80 bit doubles, which goes three orders of
magnitude deeper than 64 bit.

Be forwarned that searching for deepzoom images is very time
consuming. A fast computer helps. We don't really know yet how useful
SOI will be with arbitrary precision, but it seems promising enough
to try.

Thanks Jim, that did the trick.  Odd bug, no?

Word to Sylvie: now that I've finally gotten around to making images
with gravijul-v3 (about 3 dozen), it appears it's in jeopardy.  Looks
like you'll need to re-publish, but please name the repaired formula=20
as an alternate (*a, *1, or something) to spare those who got=20
sucker-punched along with you.

Question to the Fractint gods: could you please document the=20
problem so that we can reconstruct the error to preserve the=20
old formulas after the fix is implemented?


Thanks, Bud


P.S.: Since a) I brought up gravijul-v3, and b) it's been two weeks
since my last image post, here are three, all adorned in sil&gold.map
and its sibling.  The first is named in honor of the Cheshire Cat=20
(stripes, you know), Monty Python, and the various "Cats" in=20
the Fractint universe.  The third is another reference to Babylon 5;=20
I had to guess at the spelling, having never seen the name in print=20
(it's pronounced "boo-gee"; I'd ask if anyone out there speaks Vorlon,
but I *do* have a *slim* grip on reality!)

Ha... at 180Mhz it takes too long.  They probably _can_ be interesting,
though... there's a whole page of them that you can access from the main
Fractint site.

Fractint 19 will run in 640K won't it? I heard it runs on even old 286's

No, I'm not thinking of running it on some old dinosaur or anything. Reason
I ask is that someone reported in sci.fractals that their Win 95 dos box
only sees 640K (which is normal when you don't set fancy DPMI properties)
and Fractint won't run. (I've run it in an unembellished DOS box without
any trouble, except it might not be able to do disk video.)

Well, the old 286 part is right, though when I tried it "just for kicks" I had
1 meg in mine :-).  Can't remember if I had it set to expanded or extended,
though.  Does Fractint prefer one over the other?

Since the list dopesn't allow binaries, they'd be submitted by some other
method... a.b.p.f or maybe FTP to someplace someone sets up for the
purpose. (The latter, preferably, since my newsfeed doesn't pick up a.b.p.f.)

    Exactly.  Sorry for the confusion, but I thought someone who didn't know
what they were wouldn't know where they were either.  Spanky only has the
gzipped versions, but install/uninstall and upgrading is so much easier with
RPM...    I've found a few packages here and there, but not the latest (3.04)
version.
    So does anyone know?

  Try the following formula:

RPM stands for Redhat Package somethingorother (Module?). It is a way to
distribute and install software used on Linux systems, most notably the
Redhat distribution of Linux. I use Debian myself, which has its own
format in additon to RPM.

So basically, he is asking for the compiled binaries for XFractint ready
to install.

Anyhow, I say that he should just get the source and compile it using
make.

I've been thinking of getting xfractint myself and adding some PNG
support with PNGLIB. PNG is #1 on my wish list for fractint. It gives
better compression (sure, not always by much, but sometimes a whole
lot), doesn't have all those patent troubles, it could do 16 bit
fractals without another file format, most good paint programs can read
it by now, POV-Ray supports it, and it has a nice sounding name. But I
digress...

because of the insane SPAM. Wld people be more likely to post? Or wld it

I thought this kind of thing was already covered in the "manzpower" built-in
formula.  Why write another one?  No insult/malevolence intended.
Nevertheless, a bug's a bug.

  I was suspecting a problem with the initial value of z and I tried
various non-zero values for p2.  In fact, the original formula works fine=

only when p1 =3D=3D (2,0) i.e. when the fast parser optimizer uses LodSqr=

instead of LodRealPwr.

  BTW, the first test should be:
  if (p1 =3D=3D 2 && flip(p1) =3D=3D 0)

Interesting program - I got to 55 digits precision in 3 or 4 hours.
I think that producing some deepzoomed images of the M-set could be
nice,
but I agree that it shouldn't be just "whoever has the most processing
power wins".

Date: 29 Mar 1998 14:07:58 -0800

Hi guys,
I read sci.fractals regularly but I'll not post there until the SPAM
issue is really solved. And I mean the SPAM email. I used to
post there a lot. It is where in the good old days one could run
something like the Grand Internet Parallel Processing Project.
The closest things to that now is GIMPS (looking for new largest
prime numbers) which are run from lists. When I see a question
posted that I can help with I reply to the author. I consider this
email list the replacement of sci.fractals. If we can keep posts
on topic it will not go the way of sci.fractals.

About a deep zoom contest and raw processing power. The
current record holder is a midget on the spike. There is nothing
imaginative about that. These midgets are sitting ducks, easy
to get to compared to others off the real line. This is because the
contours practically aim right at them.

I posted a deep zoom several years ago (before Fractint had deep
zoom) on the filament in the upper left of the 3-bud. It took special
methods to find. Even though it was a 'shallow' zoom, 10 ^ 40 something,
it was interesting and at least one person asked if he could post
it on his page.  It and other midgets on the 'thin' filaments are the
easiest to compute since the iteration counts are lowest near the
outer edges of M. And if you choose the 'correct' sequence of
branches at the Misiurewicz points you can get some nice branching
symmetries.

The really pretty filament patterns occur in closer where iteration
counts are much too high for deep zooming. If you want 10^1000
magnification down in seahorse cajon, you would have to zoom
very near the tip of one of the structures.  Midget/filament images
at the tips tend to have a certain look to them - very radial patterns.
Anything else will require high resolution images with very high
iteration counts. These take a long time to compute and have multiple
wraps of the limited color palette. To avoid these two problems
requires new formula and advanced coloring methods. Unfortunately,
arbitrary precision arithmetic is only available for the standard MSet
formula.

But then again, I could be surprised.

For those of you who like to search for midgets in the shallower
zooms (near the limits of float), I have posted thousands of them
(pars only) on my web site. These are useful for admiring the variety
of filament patterns and saving some time getting to them.

Subject: (fractint) Secant ye shall find...
Date: 29 Mar 1998 23:44:54 +0100


This probably isn't new, but here are a few PARs based on the secant
method (in this case, for finding the roots of z^5-1=0).  These ideas
were inspired by discussion with Yoshitoshi Araki, who has done some
very nice C++ coded Newton and Halley's method fractals (see
http://www.sf.airnet.ne.jp/josh) and has just moved to Fractint.

As the secant method requires two seed values, there's great scope
for modifying the shape and texture via the input seeds: vanilla
Newtons; Newton 'islands'; complex curling webs; and spiky biomorphs.
 To give extra variables to tweak, I've also added a relaxation
factor (as in Chris Green's Newton work) and a mid-iteration function

What other formulas would you like to see ported to arbitrary
precision? I'm not offerring to do do a whole lot of formulas, but if
there are any particular formas already in Fractint that you would
like extended to arbnitrary precision, let me know. So far no one has

Jay, I liked that page, and am wondering how you managed to scale and rotate
each mini-Mset to match the original set.  Did you do it by hand/eye, or do you
have another method?  I'd like to know because I'fe been wanting to try some
image algebra (adding or subtracting the pixel values of two images) on two
images of mini-Msets, and would need to get them aligned and scaled to the same
orientation and size in order to do this....

Greetings,

When this frm was first posted to the list, along with the various changes,
I could only file this in a vague "when I get to it" file. Having finally
taken time to "get to it", I think I see the attraction. The first two pars
I posted with this frm were very similar. These two are also similar to
each other, difference being in the color maps. One is one of mine (same as
on the first two), the other is as noted "Jacco213".
Mr. Christenson's gravijul is quite remarkable, IMO. And there are
variations of it yet to go through????
Not to worry, I will not be posting all of the pars/maps, just every once
in a while - maybe. If I ever get anymore time...

Actually, arbitrary precision is already implemented for four types: =

Mandelbrot, Julia, Manzpower and Julzpower. (Extremely slow for those las=
t =

two types!)

What it sounds like we're asking for, actually, is an arbitrary-precision
formula parser.  Then we wouldn't need particular formulas ported to arbitrary
precision, we would just re-write them (assuming that we find a need for
deep-zooming).

Actually, how many .pars do you see that are from built-in types anyway? ;-)

Exactly why a C++ class would be great to have... I found a couple, one if
which uses Number Theoretic Transforms and is very fast... I have yet to
fully understand how it works...  But I don't think it would be hard to port
anything to use it, since it works (for the most part) like a regular double
or whatever.

I used a special C++ program to compute the size and rotation, it was part of
my
area of the MSet project.

An interesting idea. I have not had any luck using the pixel variable in
Fractint to do this. I once asked what the units of this variable are, but
it still is a mystery. Consider the simplest task, merging the regular MSet
with the largest midget for which we have exact values for their bases:
+.25 and -1.75.  Now a shift of one by 2 units should line up the bases.

But look at this

frm:classic-shift (XAXIS){ ; Jay Hill, 1998
continue = 1,
z = 0,
zc = c = pixel+.25 + ((pixel-p1)*p2) *whitesq
   :
if (|zc| > 40)
    continue = 0
else
    zc = sqr(zc) + c
endif
continue == 1
}

classic_shift   { ; Jay Hill, 1998
  reset=1960 type=formula formulafile=color101.par
  formulaname=classic-shift passes=1 center-mag=0/0/10 params=2/0/1/0
  float=y maxiter=256 inside=0 outside=summ periodicity=0 symmetry=xaxis
  colors=000<14>S9w<15>wJTzKU<30>21100\
  0000<14>000010030<29>0z0<30>02000000\
  0<14>000110330<29>zz0<30>220000000<29>000
  }

The whitesq variable is supposed to be 0 or 1, but it seems to be actually
some screwball scaling factor also. The size and shift of the second image
is incorrect. If I try to scale one, like you say, so that the bases line up
AND
the size of the midget is the same as the cardioid, it never happens.

It seems to me we should put p1=shift and p2=scale and get overlap. It fails.

Another question, while I'm at it. I asked before and I thought I understood
someone's answer, but why will the xaxis symmetry not work in the frm?
I can only get symmetry when I put the command in the par. This must be a bug!

Jay

Unfortunately, that's much harder <grin!>

I think it's 'cos you have "outside=summ" in the par. Fractint ignores
those symmetry conditions when the outside is coloured anything other than
"<nnn>" or "iter" even in the case of the built-in bog-standard Mandel
(which to look at also shows _why_ it's ignored.)

Hi Jason,

I figured it out.  The difference between working and not working code
is sometimes only a few characters.  :-)  Using this image, you can
sure see the distortion of one midget vs. the main cardioid.

frm:classic_shift { ; Jay Hill, 1998
; shift one midget over another, merge images
; p1 = shift of first midget
; p2 = scaling factor of first midget relative to second
; p3 = shift of second midget
; use  outside=summ periodicity=0 passes=1float=y
continue = 1,
z = 0,
zc = c = (pixel+p3)*(1-whitesq) + (pixel/p2+p1) *whitesq
   :
if (|zc| > 40)
    continue = 0
else
    zc = sqr(zc) + c
endif
continue == 1
}

  and a suitable scaling lines up one other feature.

Wow... no kidding!  This is great stuff... and I do see that there is more to
matching mini-Msets than meets the eye.  Hmmm... describing the Mset using just
a compass and straightedge seems less and less likely all the time.  Thanks for

If I remember right, I've run fractint 19.6 quite successfully on an 8086
with 640K. I think it was 19.6, anyway. It wasn't fast, but if you
weren't looking for past-integer-math-limit zooms, it wasn't all that
slow either.

The copyright issues have been beaten to a pulp on both mailing lists.  To
quote Agatha Christie (with no intent to infringe on her copyrights :))) ),
there is nothing new under the sun.  And it is STILL under debate in the
fractal-arts mailing list.

I've culled all the copyright related messages I could find from messages
I've saved, and put them all together in order, more or less (288K so far).
 I
sent a copy to the last person who posted a copyright question on the
Fractal-Arts List, in hopes of answering his questions on the issue.  I'll
be sending copies to anyone else who asks or answers theoretical copyright
discussion questions on either list, and also to anyone who writes and asks
for a copy.  I really hope that everyone's new questions will be answered
by everyone's old answers, and we can stop debating this question!

Deeper thought reveals that I'm not completely sure it was 19.6; it might
have been a release in the 18s? I can look up the timing on this when I
get home, I recall that there was a major new release while I was running
this and I'm not sure whether I upgraded to it or not.

It really wasn't a challenge. This was just the machine that I had
availible at the time...

I think that's a good idea, Bill.  I've been thinking of putting together a
similar compilation of discussions on printing fractal art.  Of course,
that discussion will go on, as technology changes.  But I think some of the
info imparted to date is timeless.

If we move forward, I'll contribute the copyright file I've built, and the
printing file I plan to build.  The only real problem I can see is that the
files I've put together aren't List specific.  They include postings from
both lists.  But maybe that's not a problem, given the generic topics.

Maybe we could store it in the archives?  Tim?

Peter,

 - 1. If, possessing a hypercosmic computer, you were to magnify the
 - Feigenbaum pt by, say, 10^googolplex, what wld you expect to see. That is,
 - considering the M-set abstractly, so screen resolution is not an issue;

Some points (Misiurewicz points) become increasingly self-similar as you
zoom.  Although I don't think the Feigenbaum point is a Misiurewicz point,
my zooms on it seem to be pretty self-similar.  Finding cool stuff in the
M-set is all about getting points that aren't self-similar.

 - 2. People say the M-set is bottomless, i.e., one cld, in theory, keep

 - sequence of 0s, might one finally run out of things to see in the
 - M-set -- hit a blank screen, so to speak.

While it's true there might be long sequences of seemingly non-random
numbers in the decimal expansion of pi, I don't think this would keep on
indefinitely.  That is, if at any point the decimal expansion settled into
a repeating value, then pi would not be an irrational number, it would be a
rational one, one that can be represented as the ratio of two integers.
There's a big difference between the two.

There are areas of the M-set which are incredibly dull, and there are areas
which are interesting.  Because the boundary of the M-set (the edge, not
the interior) has been shown to have dimension 2, I don't think there will
ever be a point where you find a flat edge in the set.  If there were
anywhere a flat edge, the dimension couldn't be 2, because that portion
(however small) would have dimension 1.

It would approach perfect scaling, with an exact angle along the buds

space.

Nobody really knows about the digits of pi, but this doesn'thold for M.
For instance if you zoom at the spike tip to any magnification
whatsoever, then look for where a boundary dives in toward the spike
side, you will home in on a midget with all the attendant detail.
Two mathematical proofs:
1. M's boundary has dimension 2; therefore it has detail at all scales.
If it ever did smooth out it would have dimension 1, not 2.
2. There are algebraic formulas for the lemniscate boundaries of the
components of each period. These are obtained by setting |(f(z)^n)'| =
1, where ^n for the function means n-fold compounding, ' denotes taking
the derivative, || takes the modulus, and n is the period in question.
Setting (f(z)^n)' = 0 locates the centers of components. This latter is,
for the regular M-set, of degree 2^(n-1) and thus has 2^(n-1) roots. It
can be shown that the roots are all distinct, and thus new roots, and
new components of M, must be found for ever higher periods. It is harder
but not impossible to show that the larger you take n, the smaller the
components, so there are new components at all size scales.

Well, there is indeed a quantum-mechanical limit to the total processing
your hypercosmic computer could do... if we assume that our guesses about
quantum mechanics and about cosmology (specifically the mass, energy and
lifespan of the universe) are correct to some degree, we could put a
pretty fair upper bound to it. Say, a guess within 10 orders of
magnitude, which on this scale isn't so bad. I'll take a stab at it later...

You couldn't run into an infinite sequence of zeros or anything else
periodic in pi. The M set also doesn't repeat itself. However, the notion
of "interesting new things in the m-set, as opposed to old things
repeated in a not-quite-completely-self-similar fashion" is difficult to
quantitate, as they say, so I think we might be able ot run out of those...

Actually, quantum mechanics would indeed put a limit on the computing
power of the universe. Hadn't thought of it quite that way before. When
my brain recovers from today's work, I will attempt to estimate the
computing power of spacetime. Assuming the correctness of the standard
model and the approximate correctness of comsological theory, we could
get maybe within 10 orders of magnitude, at a guess, which isn't bad at
this scale...

who? Pi doesn't have an infinite series of zeros in it, that's quite
provable. The M-set is indeed analagous, as I understand it, in that it
will not at any depth repeat exactly. It won't hit a blank. However, the
human definition of "interesting things to see, as opposed to endless
semi-similar little mandys" is what scientists like to call "Er,
difficult to quantitate..."

I responded (that same day) to the individual that requested my "wishes
in this matter" by stipulating three ways in which I will allow my
images to be used.  I have yet to here back from them.  I have also sent
an email requesting their decision as to whether or not they wish to
pursue the use of my images, and still no answer.  I will try another
email before investigating this person and the companies they may be
dealing with.

So..... I guess a few questions on the topic of Fractals and Religion
would be best left off of this discussion list??  ;-}

Thanks again,
P.N.L.

     Why do most folks hate cynics so much?
       Because we're almost always right.

<sigh>... I suppose so, for now, at least.  Best let Science and Religion (I'm
thinking Eastern philosophy, mainly) get to know each other a bit more first.
And let Bell's theorem ring in people's heads for a while... And I think we'll
want faster computers, and Virtual Reality gear before we go slicing up
quaternion sets in real-time in search of... oops, there I go!

Oh boy, here comes the future!  (Your choice:  :-P   or   8'))  )

I've heard of people (lifeforms?) worshipping the Mandelbrot set... in science
fiction.  Don't know where I heard that; perhaps on this very list?  I won't
even speculate on the actual existence of such a cult. :-)

Hi Team Fractals:

There's been some talk lately on these two fractal list servers about
copyrights. Here's an FAQ I gleaned from news.answers. Hope it clarifies
some things for you.

I would like to know how to get hooked up to the sci.fractals server. I've

sci.fractals is a newsgroup on usenet.

Here's a general explanation of usenet

Hi Team Fractals:

I've read with great interest the comments from some of you pertaining
to the way sci.fractals has recently turned into a garbage heap. Being a
frequent visitor to the newsgroup myself, I too am saddened with the
happenings there.

There is another newsgroup for fractals which has gone unused in recent
years. It's bit.listserv.frac-l. Some time ago I posted a "is anybody
there?" message and got a couple of responses from the college set.
Outside of the discussion that resulted from these contacts, basically
exchanging information about ourselves, there was no talk about
fractals.

And yet, up until around March, 1994, there were loads of informative
messages, many of which contained exchanges of formula and parameter
files for Fractint, which have been archived at a Web site whose address
I don't have at hand at the moment. Quite a bit of what we're discussing
here was talked about back then, hardware, software, uses of fractals in
science, business and industry, etc.

The owner of the list has kept the Usenet group open but it appears that
everyone has drifted away to sci.fractals. Maybe now is the time for
them to return to their fractal roots at frac-l?

In my experience the bit. newsgroups and listservs associated with them
are no longer very widely distributed. Particularly to those outside the
college. set...

PS. If you get out your Red/Blue FractoGlasses, you can see two

The parameter and formula files for Fractint are included below.
Copy them into a quickie.par file for quick loading into Fractint.
For longer term use, copy the 'frm:' block into a FotN.frm file.
But this time leave off the 'frm:' part.  Then copy the rest
(the par parts) into your FotN.par file.

Subject: (fractint) Copywright and common sense
Date: 31 Mar 1998 21:43:44 -0300


Hello everybody:
    I=B4m not new at the list, I have been here since, I dunno, maybe a year
more or less. I haven=B4t send any message to the list because of two valid
reasons:
1) My math is almost zero.
2) English is not my native language (BTW, it=B4s spanish)
3) I=B4m still trying to learn to use Fractint.
   Yes, I know: these are three reasons, but take another look to the first
point.
Since I was in the list (enjoying myself with te pars, the fotd, and the
KNOWLEDGE of every single artist, the subject of copyright have been taking
place every three months or so. I love the work of Jim Muth, S. Gallet and
all of you, but I think that we can make some common sense about this.=20
    I think that a par posted in the list is property of the artist who posted
it. This is something quite obvious. Maybe the artist have spend hours
developing a formula and then hours again making a par accordingly to it.
So, if I print one of S. Gallet pars and sold it I=B4m violating his=
 copyright.
    But, if I take her formula, and I search and zoom and rotate the palette
and obtain another image...=BFwho is the owner? The big work have been done
by Gallet, I have just merely play with Fractint...
    When I develope my BIG & SUPERB FRACTAL FORMULA, I want the credit for it.
    So...=BFnobody can ask a lawyer of the basics of copyright images made with
Fractint? I can=B4t do that, since I live in a country that his Supreme Cour=
t
has dictaminated that software has not "intellectual property". Or in other
words, I can copy Microsoft Office and use it (or copying to a friend)
without paying a cent to Mr. Gates...(do you believe that?...it=B4s=
 amazing...)
    I=B4m a medical doctor, not a lawyer, but =BFnobody has a
friend-cousin-uncle-father-lover-familiar who is a lawyer and ask him what
are the "YOU CAN=A8T" and the "YOU  MAY DO THIS"? Simple terms, for common
people. Enumerated, preferably. And some examples too. And maybe post them
in Spanish, French, Deutch, Portuguese, English, Japanese and Swahili. Lets
say, like this:
-You can=B4t copy a formula
-You can=B4t copy a par, even if you rotate the pallette.
-You can make a zoom of a fractal, even if it=B4s another artist, etc, etc.

Well, I=B4m going (hurra!)
Sorry about my english ( "Me Tarzan, You Jane" English for Dummies,
Zopilote Press, 1933)and my apologies for the large message. See you in
Mandelbrot, if a=3Dpixel and z=3Dz^2+c.
  =20
  =20

Subject: (fractint) Secant Formula Variation
Date: 31 Mar 1998 19:02:17 -0600 (CST)

comment {
The recent posting by Ray Girvan of a secant method formula
reminded me of an article I'd read about the method several
years ago.  I dug around and found it - it's THE METHOD OF
SECANTS by John Dewey Jones in the journal of Computers & Graphics
Vol. 15, No. 3, pp. 451-454, 1991.  The article includes some
images produced by the solution of sin(z) = 0 using unusual
starting values for z0 and zi (z0 = pixel and z1 = flip(z0).
I've modified the function to sin(z) - p3 = 0 and I use a
variation of the atan rendering method.  I've used a single
range of colors in these images, which gives them a nice
metallic look as well as a nice 3D effect.

Subject: (fractint) Copyright:  Some Pragmatic Thoughts
Date: 31 Mar 1998 18:38:46 -0700 (MST)

Over the past several days, many philosophical and legal issues regarding
copyright protection have been thrown around on the fractal-art and
fractint mailing lists.  This post addresses none of them.  Rather, I
present some thoughts I've had about the day-to-day realities of
protecting one's artwork.  These aren't necessarily recommendations, but
more like suggestions, to be considered if one is serious about their
fractal art.

* Develop a style and get good at it.  Of course, this is easier said than
done.  But having an artistic style makes your work more easily
recognized, which can be important if you ever get into a "it's mine!"
battle.  You can then point to your body of work in the same general style
as evidence of ownership.

* Take good notes.  Notes are a good way to keep track of where you've
been and what you've tried.  They also show a history of your work, which
can also be used to defend your position.  Sharon Webb illustrated this in
a recent post wherein she listed the 347 reasons why a given fractal was
hers, and probably not the same one that someone else made.  And, if
you're ever called on to explain your latest masterpiece to CNN or the New
York Times, you've got a headstart.

* Control your exposure.  Rather than spamming the world with your latest
creations, keep a limited portfolio on a relatively few sites.  This,
combined with your notes, will help you know where your work is going.
Also, if you've got less work out there, you'll have less available to be
stolen.  Try to deal with reputable sites that you know.  Make sure that
you get the appropriate credit if your work is shown at someone else's
site.

* If you value your work, let it show.  There's nothing wrong or immoral
about placing copyright notices and/or your name on your work.  Granted,
it won't keep someone from stealing your art if they really want to, but
it will help Elmo T. Clueless to know that it's not public domain.  You
might want to put copyright notices on your site, put a signature on your
image, and/or include a digital watermark on the image.

* Get paid.  If you're so inclined, there's nothing wrong with asking for
licensing fees or royalties if someone wants to use your stuff.  If
someone commissions you to create a fractal for them, ask for a rejection
fee if they don't like it.  We pay for just about everything else we use;
your art doesn't have to be different.  This may help establish you as a
"professional" or "serious" artist.  It may not help you protect your
work, but it's always nice to cash the checks.  :-)

I don't know what Usenet Newsgroup services that USA Net offers, but if
you can't find any of the following under your provider, then you should
send them an email requesting that they be added.

Newsgroups:
    news:alt.binaries.pictures.fractals
    news:alt.chaos
    news:alt.fractals
    news:alt.fractals.pictures
    news:bit.listserv.frac-l

Also, you might wish to use the following website that allows one to
search through many of the Usenet Newsgroups by keyword, User E-mail,
etc.
