Subject: (fractint) 4 pars
Date: 01 Jan 1999 12:58:29 -0500

Happy 1999!

Here're four gallet-8-08 pars, derived from Jim Weaver's posting
yesterday.
Jim - Good luck getting your new gear up & running..  I also plan to
upgrade
computers this year (If the tax refund materializes as hoped <G>).

Regards, Paul DeCelle

I am keeping a collection of every par and frm posted to this list, the
first one is the door3 par posted by Bill Decker a few days back.  It will
all be in a big par file. It will be available upon request.

Subject: (fractint) What did I do wrong?
Date: 01 Jan 1999 16:59:09 EST

I saved the following posting- maybe my mistake was trying to save two pars as
one, or maybe I saved a form as a par.  When I access this one- it tells me it
cant find gallet-8-08.

Any ideas?
Thanks

Try putting "frm:" (without the quotation marks) in front of all the formula names
in this posting. Thus, you should have: frm:Gallet-8-08  etc. Save changes to the
file then try to run it in Fractint.

I guess I am not doing this right.  Still coming up empty.

I guess because I do not have the file _p.frm, I am having the problems.  If
someone could post that, I'd probably get it to work.

Thanks

The file _p.frm is part of the large ORGFORM compilation of formulas which you can
download here:

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

It is possible that the method I suggested previously doesn't work for you if you
do not have the latest version -- 19.6 -- of Fractint. Embedding formulas in such
a manner into par files does not work in earlier versions. If you don't have 19.6,
you can download that too at the above address.

As an alternative, you can separate the pars from the formulas in any of the
postings on this list in which they are presented together. Make separate files of
the pars and formulas respectively, saving the former with .par extension, the
latter with .frm extension. If you do this, however, be sure to delete and frm:
prefix which may be attached to the formulas.

I am using 19.6.  Perhaps I've overlooked something simple.
Thanks for the link.  I'll download the frm files I need.

I had that problem. When you put the frm: in front of the formula name,
that tells fractint that it is a formula and shouldnt appear on the list of
entry. When trying to find a formula, it only looks in the par file if it's
not a builtin frm and no other frm file is referenced. if you remove the
reference to _p.frm (formulafile=_p.frm) it will look in the par file
itself and then it should work.

Happy New Year,

The December par collection from these pages is now available at:

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

(just the parameters)

or, if you prefer the pars with their original messages left intact you can get
this version:

http://www.homeusers.prestel.co.uk/crosstrees/fml.htm

An updated companion formula collection (frac_ml.frm) is available from both
sites.

cheers,

Hi Sylvie,

My Fractint 19.6 doesn't recognize reset=3d1960. What should do to help
it? And, by the way, your timings of your recent pars (and for, that
matter, those of Jim Beau) are so far to the right that they wrap around
and, not the being behind a semicolon, are not recognized either.

My best to you as always,   Lee

I'm not sure how UF treats the "reset=" parameter, but your par got
infected by the dreaded "3d" disease.  Just remove the 3d from between the
= and the 1960.  It's an artifact of some binary/text translation.

  Ah, the "=3D3D" disease...  I am emailing you these pars in a zip file.=

  As for Jim's pars, I always have to edit them so that Fractint can read=

them.

Hi, Everyone --

Here are seven nice quick-generating pars - "Michigan_1_2_99" pretty

I seem to be in a somewhat metallic coloring phase, lately...

Jim-- Nice image!  BTW, my time (P60) was 10m37s, or about 3.3 times

it's me again.

I rebooted my machine and started fractint solo in pure DOS-mode. Now the=

time is
2:33.63!!
Even on my P166 the image only needs 3:30.53 in pure DOS-mode.

Cheers --Jo Weber--

Hi Jim,

Beautiful image...like a great throned samurai displaying his
magnificent robes. Nice first for '99 and your 'puter. But I join
JoWeber in wondering about the time. My P200 did it in 3:10:15 @
1024X768.

    Hmmm......I guess maybe there's a bit of tweaking to be done here.  If
anyone who is familiar with Windows 98 and knows of any suggestions I'd be
grateful for some tips.  Also, I'm running Fractint from a shortcut icon that
jumps to DOS.  I tried running directly from DOS and only shaved about 3
seconds off an image. :(   I do have a lot to learn about Win98 such as how to
trim all the fat away and get down to the meat.
    Anyway, at least I can see my stuff in 1024x768 now.  Has anyone ever
converted their images to BMPs and used them on the maze screensaver in Win98?
Now THAT's really cool.  :)     Enough text for now~

I?m not sure if someone posted a recent par using the Lesfrm34 formula =

if I started from scratch, but something got me started on investigatin=
g
what you could do with it. Crosses are the connecting theme of most of =
the
images that I liked.

Vine-lattice2 was the first image that I was satisfied with. It is eith=

finely etched, gray, matte surface or a general glowing source obscured=
 by
a vine-like lattice. Depends on how your eyes are processing 2D images =
into
3D at the moment. Zooms or slight color shifts accentuate a glassy, gen=
tly
rounded surface.

Disassembly was a derivative of the vine images. It seems to be coming
apart (or coming together.) The fine lines seem to suggest jigsaw puzzl=
e
shapes, adding to the sense of fragmentation.

Biaxial-subframe is a derivative of Disassembly. It is so mechanical in=

I uploaded a new page to my Geocities website containing images I
created with simple formulas I wrote based on some equations of curves I
found in an ancient textbook of elementary analytic geometry. I hope you
enjoy them.

I also played around with making bordered backgrounds; some fractal,
some floral, and others. A link to the site containing them is also
found on my Geocities page.

Greetings,

    As I am on the verge of building a machine [ 440BX / PII450 ] I see the lure
of AGP and wonder how, if I choose to use AGP, it will impact images done in
fractint,
and or, imaging in general.
    Is anyone using an AGP card and if so [ or if not ] do you have any input?
I realize this is off topic. Anyone can write me direct if they would be
inclined.
Thank you,
Steve

Date: 05 Jan 1999 21:31:21 -0800

Greetings...

I have always heard that Fractint is blindingly fast
compared to other such programs because it is
based on integer math instead of floating point math.

However, to do this it makes certain "approximations".

Could this mean the results obtained are only
"approximately" Mandlebrot, perhaps becoming
more and more approximate as iterations and
zoom levels increase???

Are we looking at "true" fractals, or are we just
doing dances with Wolves
in Mandelbrot's clothing???

(I shall now "duck and cover"!!!)

Hi Christopher,

Fractint uses more floating point than you might think,
since the current Pentium processors have very fast
floating point math.  After you zoom into the Mandelbrot set
a certain amount you pass the limits of double precision
and Fractint switches to extended precision math. So you
can zoom into very high magnifications and get very
nice results.

Subject: (fractint) Taking it for granite
Date: 06 Jan 1999 07:33:03 -0500

(Sorry, I couldn?t resist the chance for a silly Malapropism.)

These images have the general theme of carved stone chased with silver =
or
gold. The fractal is not fully resolved in the regions where very fine
striations are well below the resolution of the screen. The result is a=

fine textured, speckled stone-like surface resembling polished granite.=


The pars are presented in time order in which I created them. (I saved
about 25 pars on my journey in this quest of the best rendition of what=
 I
imagined that I saw in the first par in the series.) I?ve got some comm=
ents
that try to let you inside my head as I pursued the ?perfect? image fro=
m
this fractal.

Padds was the first of the images that I saved. It has a slightly diffe=
rent
formula set than the others (asinh rather than sin). I decided to see w=
hat
the pad-like stone surfaces could be evolved to.

Pebble-flowers finally settled on the formula set that I liked, but the=

challenge now was to see if I could find a part of the fractal surface =
that
reminded me of something ?real?. I got some good detail in the dark are=
as
of the image that I would have difficulty in achieving in later pars.

Pebble-flowers3 seemed like something I could work with. The compositio=
n
was kind of symmetric (something I usually don?t like) and seemed to co=
nvey
a stone carver?s decorative intent.

Pebble-flowers4 ends up being my favorite. The granite surface has a mo=
ssy
shade and the moon silver holding the flower petals in place has a mute=
d
sparkle. For some reason, I imagine that the carving is the artist?s
decoration of a natural rock crevice that crosses a stream bed. Water
flowing over this carving seems natural given the dark green shadows in=
 the
crevice.

Pebble4p is a fantasy in garnet with gold tinged clasps holding the pie=
ces
in place. Just a side excursion, I liked the glassy reds and gold tinge=
s
but it seemed too unreal for me.

Talus-pebbles is a wider view of a pebbled scene. The rounded rocks and=

broken gems lie in cemented heaps like fossils; an ancient treasure, no=
w
petrified. I like this one almost as much as pebble-flowers4 since it s=
eems
to have a story behind it. Still, the simpler story of pebble-flowers4 =
wins
out. I can see now that I should have stayed with the pebble-flowers4
colors.

Pebbles-wh2 was an attempt to get more detail visible in the depths of =
the
crevices in the carving. Didn?t work. Too light and still no better
definition of the carving in the crevices.

I finally gave it a rest today and decided to try to document the evolu=
tion
of this particular series. I think pebble-flowers4 is still the best
rendition I have to date. Like most other series of this sort (where I =
try
to evolve a fractal), the best result seems to be one of the attempts i=
n
the middle of the series, in this case number 13 in the series.

Without saying so directly in this tale of search and reward, my search=
es
tend to focus on finding fractals that tell me a story. Hmmm, I?ll have=
 to
think about that. I'm not sure that it applies to me all the time.

Anyone care to comment on my attempt to tell you how I worked this frac=
tal?
Anyone see a way to get that damn detail in the crevices to become more=

apparent?

It depends, I think, partially on your drawing method.  If you choose the
"guessing" type (where the fractal appears to be "focused" in to a clear
picture) then I think there's the possibility all the pixels may not be the
exact correct colour.  However, choose the 1-pass option and I'm pretty sure
the fractal produced is perfect - regardless of zoom level.

Chris,

 - I have always heard that Fractint is blindingly fast
 - compared to other such programs because it is
 - based on integer math instead of floating point math.

Actually, these days FractInt is only moderately fast.  It's not the
fastest (I believe that prize currently goes to Fractal eXtreme) but it's
far from the slowest.

FractInt is as fast as it is for several different reasons, not just
integer math.  It's also fast because it takes advantage of fractal
symmetry (when it can), because it uses solid guessing to eliminate
calculating portions of the image, and because it uses periodicity checking
to detect periodic orbits early in the iterating sequence.

The idea behind using integer math is that it lets you work with 32-bit
precision instead of 64-bit precision.  Prior to the Pentium this was a big
win; 32-bit precision could be done with integers the core CPU could
handle, while 64-bit precision required using the (slow) FPU.  With the
Pentium, the FPU is fiendishly fast, and the advantage of using 32-bit
precision is gone.  In any case, using 32-bit precision does cause some
distortion when you zoom in far enough; FractInt automatically switches to
64-bit precision when necessary so you won't notice (usually).

Solid guessing is the progressive refinement process, but on each
refinement pass, FractInt checks each block to see if its neighboring
blocks are all the same color.  If they are, it stops refining that block.
This can eliminate a lot of calculations, although in the more detailed
areas it is less effective.  FractInt also offers boundary tracing, which
is a similar concept--outline areas of solid color, and don't calculate the
interior of those regions.

Periodicity checking is about paying attention to the iterations and
looking for periodic patterns.  Most of the points that do not bail out of
the M-set calculation fall into periodic orbits.  If these can be detected
at the start of the periodic cycle, then it is safe to skip the rest of the
iterations, since they will just produce repeating values.  This allows
interior regions to be calculated very quickly.

 - However, to do this it makes certain "approximations".
 -
 - Could this mean the results obtained are only
 - "approximately" Mandlebrot, perhaps becoming
 - more and more approximate as iterations and
 - zoom levels increase???

In one sense, every image is an approximation, since the precision of our
computers is always (at some point) limited.  Any algorithm or technique
used to avoid doing the actual work of generating a fractal will introduce
some errors, sometimes very subtle.  Solid guessing fails on thin strands
of detail.  Periodicity checking fails on spiral arms (since these often
exhibit periodic-like behavior before diverging).  And limited precision
produces blockiness when the error between the correct pixel coordinate and
its closest approximation in the limited precision becomes significant.

If you continued to zoom in FractInt without switching away from integer
math, you would certainly be getting a more and more distorted view of the
fractal.  Similarly, if you zoomed in on a spiral arm that was incorrectly
rendered because of periodicity checking, you would be getting a more and
more inaccurate view of the fractal.  Acceleration techniques are tools,
and knowing when to disable them is important if you are interested in
accurate fractals.

The fact that there is such close agreement between the "true" fractal
shape and the approximations provided by acceleration techniques is
precisely what makes them valuable.  If you have no confidence in limited
precision having any resemblance to the "true" fractal shape, I can explain
further.

It uses floating point if you select Floating point algorithm = yes in the

You are correct as far as you go. The one pass option with
symmetry=none and periodicity=0 is relatively accurate.

However, there are still two large inaccuracies.

1. The maxiteration limit has to be infinity for perfect accuracy. For
any finite value of maxiter, it is possible that some points are "in
the lake" that ought not be. For example, if the maximum iteration
is set for 1000000 and a particular orbit has not escaped by then,
the pixel is colored the "inside" color. But for all you know, the orbit
was about to escape, and in fact would have escaped at iteration
number 1000001. So that point is colored wrong. The "lake" is
always slightly too big.

2. Computers can only represent complex numbers approximately.
Even using arbitrary precision, the orbit is not absolutely correct.
Some of the fractal algorithms are extraordinarily sensitive to very
small changes and show this clearly. One example is popcornjul. I
have been experimenting with this, and small differences in coding
logic that, for example, cause an intermediate value to be truncated
to 64 bits, can change many image colors.

Tim


Given these two facts, it is amazing how well computers do. Try
the default mandelbrot using 1500 digits of arbitrary precision and
with maxiter set to 32000 and see how different it looks. The
answer is not very different!

Tim

Date: 07 Jan 1999 23:38:00 +0100

I recently finished making a new version of my web gallery, and
uploaded it yesterday.

I renamed it 'Jacco's Fractal Pages' because I discovered two other
Jacco's Homepages on the Internet.

Some changes and additions are:
I got rid of the frames and most of the non-fractal graphics (do I
hear 'Hurray!!' ?).
I added a gallery with new fractals, a page with my contest
submissions and another zip-file of color maps for Fractint.
Some of you already had a preview of the color maps.

The URL hasn't changed, it is still:
http://wwwserv.caiw.nl/~jaccobu/index.htm

I hope you will enjoy it and let me know what you think!
Bye!
Jacco

  Hi Jacco,

   Jim Weaver here.  Just saw your pages and wanted to tell you I really liked
them.  By the way....are you a Frank Zappa fan?? The reason I ask is a few of
your images have titles I recognize from his music. I have about 23 or so of
his vinyl albums that I've collected over the years. Too bad he isn't around
anymore.
   Anyway, great work on the site.

     Take care~

Jacco - I visited your updated site & I like it very much.  I also
spotted the Frank Zappa inspired titles.  Could there be some bizarre
connection between enjoying Zappa's music and being interested in
fractals?  I've noticed a few fans on this list alone:-)  FZ would love
it--

Anyway, here's a par that may (or may not) have anything to do with
Zappa!

One more reason to love this list !

Yes, there is a connection. Zappa's music, just like a well crafted
fractal, is beautiful, complex, sometimes chaotic, and it reveals
more beautiful layers when you dig (or zoom) a bit.

So far the detected Zappa fans at this list are Jim Weaver,
Jacco Burger, Paul DeCelle and myself. Not bad, not bad....

Incidentally, I'm a member of one of the thousands of groups
trying to crack the RC5-64 key. And our group is called, you
guessed it, "alt.fan.frank-zappa RC5-64 Crack Decryption Squad"
So there should be another strange connection...

And BTW, I'm still working on my FZ Memorial Fractal Page
(to be displayed at my Franktal site), I'll make the announcement
when it's finished. Meanwhile, enjoy these ZappaPars ;-)

Hi, guys,

I'm sorry I can't do my own fractals as well (I assure you that soon they
will be in your screens), but I'm a Frank Zappa's fan too. By now, I'm
looking at your fractals and as Miguel Fliguer said, the connection betwe=
en
complexity in both fractals and Frank's music is, excuse my words,
outstanding and amazing. Paul, I'm sure FZ would love it... He does fract=
al
music, doesn't he?

Very nicely put, Miguel, and it looks like an appropriate moment for
this lurker to say "hello" to the list! I'm a big fan of both FZ as well
as fractals.

I've been dabbling with fractals for a few years now, firstly on the
Atari ST, then on the Amiga (using an earlier version of Fractint
amongst others), and now on the PC with Windows 95 (and soon with Linux
once I get Fractint working properly there!).

I've still a lot to learn about what the program can do; you are all
finding some truly beautiful images and writing some wonderful formulae.

Nearly forgot - my first two pars. I'll post more when I know a bit more
about what I'm doing :)

Subject: (fractint) We're only in it for the fractals
Date: 08 Jan 1999 21:27:32 +0100

When I first tried to think of names for my fractals I really had no
inspiration. I didn't want to give them those often used names like
'Neon Spiral' or 'Blue Mandelbrot' or 'Red Alien', but I couldn't
think of anything better either...

So one day I was sitting, staring at one of my fractals on my
computerscreen, thinking and thinking: how should I call this one? At
that moment I had a record of Frank Zappa playing, and I heard him
singing: "In the dangerous kitchen..... if it ain't one thing it's
another...." and I thought: that's it! So I started reading the
sleeves of all the LP and CD records I had, and that is how many of my
fractals got their names.

So if you take a good look at my fractal gallery you might also find
some songtitles from other bands and musicians. I am not going to
spoil the fun by telling which ones they are, that is for you to
discover.

A source of inspiration for exotic fractal names are dictionaries of
foreign languages. The dictionary also provides you very conveniantly
with the meaning of the word so you can be sure you are not using
offensive words. This can be tricky, though! I know for instance that
some very ordinary Dutch words sound very rude to Polish people....

Another way of finding names is fun and very easy. Just show a fractal
to somebody, preferably a child, and ask: "what does this look like?".
You will be surprised! At least 3 of my fractals got their names this
way.

Actually, I am thinking of adding some of this kind of information to
my fractals on my webpages. I will let you know in time.

I am very curious about other people's sources for names. Anyone who
would like to tell about it?

Bye!

I sometimes use names from my classical music CD collection. Once, for

Jacco,

 - I am very curious about other people's sources for names. Anyone who
 - would like to tell about it?

Normally I just look at the fractal and think of what it reminds me of.
That probably accounts for most of the lame names I've used. :-)  Often
while exploring I will see a shape that makes me think of something, and
I'll refine the image in that direction to make it fit the name.  Sometimes
I'm just totally stumped; at that point, I turn to a few friends for help.
I do have one friend who has named several fractals who doesn't know much
about fractals at all (just that he likes them).  And sometimes it just
helps to have someone else look at the images, so that you get a fresh
perspective.

You mentioned using words in other languages. I just found a wonderful site
for that, which provides links to languages most of us have never even *heard*
of, for translation and even on-line language lessons:

I invent names for mine. If you see "Teralla" or "Krenias" or something
similar in an online dictionary it is entirely coincidental.

I have also run into this problem.  Instead of shelling to DOS,  restart the

you should be able to run Makemig with no trouble.

Miguel makes a good point - I never really thought about it that way,
but it does make a lot of sense..

Damascena, About that tee shirt - he'd certainly do a better job of it
than the one we have now.  Wear it with pride!

In keeping with the theme, here's a par from the Zappa_1 formula Miguel
posted earlier today - Took more than 30 minutes on my P60, but worth
the wait..  Oddly, activating floating point caused the fanlike
structures to disappear, resulting in a very different image.  Anyone

Welcome, Baxter!  Very nice images.  Just took a little text editing to
format them for Fractint.  I find that (using Netscape and Notepad,
anyway), if I delete any open spaces at the beginning of each line of
the par where the parameters and color info is contained before I send,
it transmits true.  You can check by opening your posting after you've
sent it by opening it from the "Sent" folder.  Other browsers probably
have similar features..

I look forward to seeing more of your work..

Hi Everyone...

We have all heard that a Fractal is Self-Similar
(but not Self-Identical) at increasing magnifications.

This means adjacent consecutive magnification levels
are not identical. Maybe very close, but not identical.

But might a (perhaps very long) sequence of such adjacent
levels not Start and End with Self-Identical shapes???

If so, perhaps this sequence may repeat indefinitely in what
I would call a "linear" manner. This is comparable to leaving
your home for a walk and always taking the same route and
then returning. This is the "First Possibility".

The "Second Possibility" is that the second sequence may traverse
different shapes than the first yet still return to the identical
"Starter/Ender" pattern in what I would call a "rooted" wave pattern.
This is comparable to leaving your home for a walk and taking a
different route each time but always returning to the "home"
location (location=pattern).

The "Third Possibility" is the zoom changes are in no way repetitive
but are open ended, ever changing and ever different.

Now, since the Fractal zoom levels continue without end, then
if the First Possibility applied, only a finite number of shapes
would be generated.

But, if the Second or Third Possibilities applied, an Infinite number
of shapes would be generated. This means the sum total of
"All Possible Shapes" which COULD be generated, percieved or
imagined would be generated by...

Mandelbrot to power 2
Mandelbrot to power 3
Mandelbrot to power 4... etcetera, etcetera and so forth.

So, somewhere deep within EACH Mandelbrot lurks
not only a Mona Lisa, but the entire Works all of ALL
the Artists who have ever been and will ever be...
PLUS a fair bit of just plain gobbledegook.

These same images (the "Infinite Set") would arise from
ALL Mandelbrots, regardless of to what power. So, at
"Infinity", the outputs generated by ALL Fractal types,
to whatever power, becomes the same, namely "every
shape that can possibly be". Strange!!!

There is of course one possible fly in the ointment of this
Fanciful Flight to Fractal Infinity...

If the successive zoom differences gave increasingly smaller
pattern differences such that these tinier amd tinear differences
asymtopically approaches zero... never ceasing to change,
but with changes becoming literally infinitesimally small...
then, no more Mona Lisa.

So, what do you folks, many much brighter than me, think???
Or does this kind of thing just give you a headache?

Christopher Springer

To my understanding, this is the case.  Each "midget" is slightly warped
with respect to the main cardioid; the relative warping is different for
each midget.

This is a common mistake, confusing "infinite" with "containing
everything".  The Mandelbrot set truly is infinite, that is, going on (in)
forever, but it certainly doesn't contain everything.  It's similar to a
sequence of numbers.  Consider any infinite sequence of the digits 0-9.
No matter what sequence you choose or how long you look, you'll never find
the sequence "THIS SPACE FOR RENT" in the sequence.  In the same vein,
you'll not find a Mona Lisa in the Mandelbrot set.

But what if we took at, say, pi. Some where in the sequence of digits we
will find a representation of the words "This space is for rent" i.e.. 20 08
09 19 19 16 01 03 05 .....
If we digitized the Mona Lisa into say 100 colors, and then made a sequence
out of the picture, line by line, we would have a finite sequence that would
have to exist inside of an infinite sequence. Could not the same thing be
said about a fractal? If we take a line straight across a given fractal and
obtain a sequence of numbers, won't there be an infinite number of possible
sequences? Just my thoughts.... :)

Strictly speaking:  probably, but not necessarily.  If pi is what is
called a "normal" number, then its decimal representation contains all
finite strings of the digits 0-9.  However, pi's normality has not yet
been proven.  But more generally, there are infinite, non-repeating
numbers that won't contain even your decimal representation of "This space
is for rent", such as the number 0.10010000100000000100000000000000001...

      No--just because a sequence is infinite, that doesn't mean that it
necessarily contains all finite sequences.

If you go to digitizing the Mona Lisa, then I'm sure you could find it
somewhere in the Mandelbrot set with some suitable transformations.  But
that would border on tweaking the answer to fit the problem, rather than
truly finding another image in an infinite fractal.

These are subtle points, and I don't mean to stomp on your thoughts, just
help clarify them.

Have you tried the mode that Sylvie Gallet wrote?  It's for a Matrox
Millenium 1600x1200, but it may work.

Thanks for the kind words.  I was able to respond like that because I had
the same question years ago and got the same response.  Likewise, I argued
that the set of midgets was uncountable, and was quite resoundly
corrected.  The short answers seem to be:  1) to every midget, a rational
number can be assigned.  Thus, the set is countable.  2) Since every
midget has an area, the set must be countable since the whole collection
fits within the circle of radius 2.

Regarding the distortions, several years ago, Michael Frame (of Union
College) and I wrote a paper about the distortions within a particular
midget, as opposed to distortions of the midgets (I mention this because I
think there may be some similarity).  The disks along the boundary of the
cardioid of a midget are located and sized according to a simple general
rule.  However, the actual disks are distorted slightly from this rule.
The distortions are distributed "fractally".  That is, when plotting the
distortions, a "fractal" results.  The quotes are required because the set
of distortions is a countable set, and thus cannot be a true fractal.
Anyway, I wouldn't be surprised to see that midget distortions were also
"fractally" distributed.

The set of midgets is countable... for each period from 1 upwards there is
a finite collection of midgets whose cardioid has this period. Thus the
midgets comprise a countable union of finite sets, whichis countable.

Kerry's right... this is tweaking the answer to fit the problem, but if the
tweak results in the appearance of meaningful relationships between answers,
then it might just be a good idea.  For example, if the same coding method were
applied to the name "Leonardo DaVinci" and to the Mona Lisa, and the resulting
encoded number sequences were found in close proximity (or intermingled?) within
pi, it might make us go "hmm."  And if that same coding method had similar
results when applied to other situations, and a recognizable pattern began to
appear in the relationships of the encoded number sequences within pi, it might
make us go "hmm!"

If what's being proposed is possible at all, I kinda doubt we're going to reason
our way to the correct "coding method"...  things in our universe might be
encoded/contained within the structure of the Mandelbrot set in a number of
different ways; perhaps in the relative angles and lengths of different
filaments, the relative position and orientation of baby brots, the relative
"roughness" (read: fractal dimension) of a filament or baby brot at a given
resolution/magnification... lotsa parameters to play with here!  And might we
need to consider the hypercomplex Mandelbrot?  I personally believe some good
stuff along these lines await those willing to explore the possibilities.

Hi Everyone...

PART I:

Thank you Kerry Mitchell, John Camp and Jason Hine for your interest and

replies regarding Infinity and All Things. Most interesting.

I agree that "infinite" will not "contain everything" if the infinity
referred to is one of stasis,
either Unchanging (e.g. continuous sequence of "1") or Looped (e.g.
123123123...)
BUT if the infinity is Ever Changing I think it will. Consider the
following...

My computer screen is set at 1024x768. That is,  786432 pixels.

So, we generate a binary sequence starting from Zero, and
continuing on up to 2^786432 (a RATHER LARGE number).

This will yield EVERY POSSIBLE arrangement of "ones" and "zeroes"
in the 786432 digit binary number. Equivalent to EVERY POSSIBLE
arrangement if "on" and "off" pixels on my computer screen. This means
(if we limit ourselves to a Black and White screen) that my computer
screen will show the set of "All Possible Images" that it is capable of
showing.
This will INCLUDE a picture of you, me, Mona, Lisa, and every cat, dog
and Fractal (!!!)
which is capable of being shown on a 1024x768 pixel black and white
screen.
This even includes "THIS SPACE FOR RENT", and many, many variations
thereon!

Now is this an "Infinite" number of images? No! Because anything Digital
has
the "Jaggies" at some level or other. But if the pixel number was
increased
sufficiently until our ability to see the image was the limiting factor
in our
perception, it would for all intents and purposes be "Infinite" to us
because
even if we further increased the screen resolution to display even
"finer"
differences of in-between images, we couldn't see the difference anyhow.

But for the Purist, what the heck, just get a nice Infinite Pixel
Screen, and
have done with it. THEN the number of images WOULD be INFINITE!

It is not difficult to see that all possible arrangements of Colour
could be
imposed on the "on" pixels of each image. But I kept that out of it for
now
just for simplicity.

Furthermore, the 2-dimensional Screen could be replaced with a
3-dimensional
Block of screens (Cube) to model 3-d images. Not only that, but for each

3-d Block Image could be opened rows upon rows of 3-d Block Sequences
showing All Possibilities for the NEXT image, which would define the sum
of all
possible motions through time. Talk about needing a MASSIVELY Parallel
computer!!!

So, does the original premise of Infinity and All Things, namely that
Fractals
may generate:

<< an Infinite number of shapes would be generated. This means the sum
total of
"All Possible Shapes" which COULD be generated, percieved or imagined >>

gain any sort of reprieve? Or is it doomed, in your opinions, and
therefore
should I go back to the drawing board?

PART II:

Has anyone considered displaying the DIFFERENCES in the same Fractal
Object in ZOOMS seperated by ONE or MORE Zoom Levels???

I think they would be still "Fractal" in nature, and this may open up a
whole
new area of "Difference Fractals" or "Subtractal Fractals" or whatever!

Since the differences should be small, especially between adjacent
levels,
they might be quite "whispy" and beautiful.

PART III:

Is there any way the Fractal Math (as performed by Fractint and others)
can be REVERSED? That is, instead of calculating at Zoom Level Zero,
then at Zoom 1, Zoom 2 etcetera, etcetera and so forth, could we
calculate BACKWARDS to Zoom -1, Zoom -2 etc.?
The same effect could be produced (I think!) by taking Zoom 1,2,3...etc
images and running them through what I shall call an "Extrapolative
Morph Program"
to extrapolate back to what Zoom 0 ("The Lake") -1, -2,-3... Fractals
should look like.
I think all Morph programs may be Interpolative ("Blending"). But
perhaps
an Extrapolative one does exist or could be written.

FRACTALS FOREVER!!! So many are so beautiful, let's push the Fractal
Boundaries
to the limit, and squeeze the Sponge of Beauty for all that is in it!!!

What do you all think?

<BR>just for simplicity.

<P>Furthermore, the 2-dimensional Screen could be replaced with a 3-dimensional
<BR>Block of screens (Cube) to model 3-d images. Not only that, but for
each
<BR>3-d Block Image could be opened rows upon rows of 3-d Block Sequences
<BR>showing All Possibilities for the NEXT image, which would define the
sum of all
<BR>possible motions through time. Talk about needing a MASSIVELY Parallel
<BR>computer!!!

<P>So, does the original premise of Infinity and All Things, namely that
Fractals
<BR>may generate:

<P><< an Infinite number of shapes would be generated. This means
the sum total of
<BR>"All Possible Shapes" which COULD be generated, percieved or imagined
>>

<P>gain any sort of reprieve? Or is it doomed, in your opinions, and therefore
<BR>should I go back to the drawing board?

<P>PART II:

<P>Has anyone considered displaying the DIFFERENCES in the same Fractal
<BR>Object in ZOOMS seperated by ONE or MORE Zoom Levels???

<P>I think they would be still "Fractal" in nature, and this may open up
a whole
<BR>new area of "Difference Fractals" or "Subtractal Fractals" or whatever!

<P>Since the differences should be small, especially between adjacent levels,
<BR>they might be quite "whispy" and beautiful.

<P>PART III:

<P>Is there any way the Fractal Math (as performed by Fractint and others)
<BR>can be REVERSED? That is, instead of calculating at Zoom Level Zero,
<BR>then at Zoom 1, Zoom 2 etcetera, etcetera and so forth, could we
<BR>calculate BACKWARDS to Zoom -1, Zoom -2 etc.?
<BR>The same effect could be produced (I think!) by taking Zoom 1,2,3...etc
<BR>images and running them through what I shall call an "Extrapolative
Morph Program"
<BR>to extrapolate back to what Zoom 0 ("The Lake") -1, -2,-3... Fractals
should look like.
<BR>I think all Morph programs may be Interpolative ("Blending"). But perhaps
<BR>an Extrapolative one does exist or could be written.

<P>FRACTALS FOREVER!!! So many are so beautiful, let's push the Fractal
Boundaries
<BR>to the limit, and squeeze the Sponge of Beauty for all that is in it!!!

<P>What do you all think?

Hi Christopher

Easily done, thanks to a debug feature left in fractint that will colour only
the different pixels in an image loaded on top of another one if fractint is
started with the command debugflag=50.

To do this just save the two images you want to subtract, load the first one,
hit 'g' to bring up the command dialogue, enter the string:
debugflag=50
hit return then 'r'estore the second image on top of the first.

Easy!

Now if anyone gets really into this sort of thing howabout composing a
difference matrix (well half matrix really)for all the types of plotting (i.e
guessing vs tesseral, tesseral vs boundary plot, boundary plot vs single pass
etc,) and putting up a page with the results, that'd be fun!

Cheers,
     Robin.

Oops! I forgot to mention that debugflag=50 puts a large file in your fractint
directory that notes all the co-ordinates of the pixels that
were different. It's called cmperr and you might want to get rid of it after a
session as it can easily reach a few meg in size.

Cheers,
     Robin.

Subject: (fractint) Next version of Fractint
Date: 10 Jan 1999 01:13:34 -0000

Anyone know if/when the next version of Fractint will come out?
It's been so long, I'd like to know if there ever will be one, or at least
one in the next year or so.. :(

For me, I still don't know which is best.. Ultra Fractal 2.0 or Fractint...
If Fractint could add True color support and a couple of other things (such
as anti-analysis) then I'd probably stick with it. However, if Ultra Fractal
just added Fractint's "Deep Zooming" (arbitrary precision), then I'd move
over to UF instead... At the moment, I don't know which to get going with :(

Will Fractint 17.x come out before Ultra Fractal 3.0 (that should have
arbitrary precision..)?
Seems the next one to upgrade wins ;)

Any thoughts on this?

Matt

Matt,

 - Will Fractint 17.x come out before Ultra Fractal 3.0 (that should have
 - arbitrary precision..)?

Um, don't you mean FractInt 20.x? :-) Even so, I don't think true color
support is slated for v20... I think it's v21 that will have full true
color support. (I am sure the FractInt developers will squash me like a bug
if I'm wrong here. :)

Now, that's a really beautiful Mona Lisa!!!

But to distinguish it from the original by Leonardo Babe, perhaps it
should

be re-named either:

"Mona Lisa on a Bad Hair Day", or:

"Shania Twain"

Any printable comments, Jason?

Speaking of differences, curiously enough, I've been experimenting
with fractals created from tiny differences between near identical
powers of Z magnified thousands of times.  The attached par file is a
sample of what is possible with this technique.

    Thanks for your work on updating the fractint resource list. I'm
sorry to hear that you won't be able to maintain it. I hope you have found
new and exciting things to keep you busy. It was a very useful resource.
I found it an extremely  valuable tool in keeping up with the constant

Subject: (fractint) Video output question
Date: 11 Jan 1999 18:03:11 EST

Hi, I'm new to this list and actually still quite a beginner when it comes to
fracint.

My question is:
 Is there any way I can send the images from my monitor while in fractint out
to a VCR or TV.  My computer has a TV out jack which is, if I'm not mistaken,
an S-Video jack.  I tried hooking this up to my VCR and TV neither of which
produced any images.  I'm thinking either this is *not* possible, or I need
some special video card or software.

I can't believe, though, that I'm the only person who has tried to do this.
Think of how amazing it would look on a 50" TV screen.

My main reason for wanting to do this is:   I play in a band, and one of the
venues that we often perform at has a big screen TV right behind where we
play.  And I want, somehow, to have the images I've created with fractint be
up on the screen while we perform.  I think it would add a lot to the whole
effect of our performance.

Any help would be appreciated.

You'd need... ponders... well, if you're running fractint from within
Win95, then I'm not sure I know enough about how Win95 DOSmode works to
tell you. If you're running fractint by booting to DOS, you might be able
to do this with some sort of DOS driver for your card, if the manufacturer
has bothered to write such a thing. What video card are you using?

               Nice alien Paul!

        Just so no one gets the wrong impression I want to state that the
jm_04 formula isn't mine, I only borrow it to make fractal art as I do ALL my
images. I most likely will never claim ownership to a formula because I don't
understand them even in the simplest form.<G> I used to think that if I knew
how a formula worked and could make my own that I could make better pics, but
that's not necessarily the case in some instances.  And besides, I'm having
enough headaches learning how to use all these programs I recently
d/l'ed....Ultra Fractal, Flarium24, Iterations, and Tierazon.  BTW, this here
UltraFractal deserves some more close inspection....I like the looks of it so
far.
   How about something in the future like....Ultra Fractint!?  There's an
idea.

         Thanks~

Well, I think I've answered my own question.
The card I'm using is an ATI Rage graphics accellerator.  And if you go into
the display options on your control panel there's a page that enables the
output device you are using.  Once you have the TV hooked up, you can check
"television" and whatever is on your monitor will show up on the TV screen.
Unfortunately, the TV doesn't come close to reproducing the colors on the
monitor.  But, for what I'm using it for it should be OK.

Why not enjoy the best of both worlds?

Fractint remains a superlative program, and it's completely free - so why give
it up at all?

Ultra-Fractal, on the other hand, is a state of the art imaging program with
almost total compatibility with Fractint.

The great fun is that you can re-work your favourite Fractint images, converting
them to true color, adding layers, manipulating layer transparency with the
alpha-channel etc... The possibilities are literally endless!

I've just posted a small selection of my Fractint images, re-worked in UF, to
the Ultra Fractal mail list if you want to take a look.

cheers, Les

almost every modern platform.

By the way, has anyone seen somewhere that I can download the Amiga

Subject: Re: (fractint) Terrain Generating Algorithm
Date: 13 Jan 1999 09:08:28 -0500

As far as I can tell from the source code, the old algorithm for Plasma i=
s
a recursive algorithm that defines the colors of the edge midpoints and
center of a rectangle based on the colors of its corners. The original
rectangle is the entire screen, and its corners are colored randomly. The=
n
the color of the midpoint of each edge is the average of the colors of th=
e
endpoints plus a random variable (presumably with mean zero) times the
length of the edge. The color of the center is the average of the colors =
of
the edge midpoints. (Note that the color values are much more precise tha=
n
the actual palette, so as to allow them to be averaged and displaced
fairly.) I can't figure out what the new algorithm does.

Note: This algorithm is technically incorrect because it is stratified
along the dyadic grid (Mandelbrot FGN p258). A more realistic model of a
terrain can be obtained by adding Weierstrass functions projected along
various directions. Note, however, that there must be a large number of
such functions. Otherwise, a "striping" effect will be seen along these
directions.

So we would start with this (where x,y are cartesian coordinates and p =
is the color value at that point):

p(x1,y2)        p(x,y2)        p(x2,y2)

p(x1,y)        p(x,y)        p(x2,y)

p(x1,y1)        p(x,y1)        p(x2,y1)

And then generate the mid points between these lines as so:

p(x1,y) =3D [ p(x1,y1) + p(x1,y2) ] / 2
p(x,y2) =3D [ p(x1,y2) + p(x2,y2) ] / 2
p(x2,y) =3D [ p(x2,y1) + p(x2,y2) ] / 2

Then each edge point gets modified up or down by a random amount.  The =
mean of zero means that the random number has an equal chance of being =
as positive as negative?  Hello!  Part that I was missing!  Multiply the =
edge midpoint by the length of the edge:

p(x,y1) =3D [ p(x,y1) + rand(10 to -10) ] * [ x2 - x1 ]
p(x1,y) =3D [ p(x1,y) + rand(10 to -10) ] * [ y2 - y1 ]
p(x,y2) =3D [ p(x,y2) + rand(10 to -10) ] * [ x2 - x1 ]
p(x2,y) =3D [ p(x2,y) + rand(10 to -10) ] * [ y2 - y1 ]

Then the center point:

p(x,y) =3D [ p(x,y1) + p(x1,y) + p(x,y2) + p(x2,y) ] / 4

What happens if (when) p goes beyond the 255 palette limit?  Or, am I =
taking the average too soon for the edge mid points?

This is where my ignorance shines through, I'm afraid, but what is a =
Weierstrass function?

As far as I can tell from the source code, the old algorithm for Plasma =
is
a recursive algorithm that defines the colors of the edge midpoints and
center of a rectangle based on the colors of its corners. The original
rectangle is the entire screen, and its corners are colored randomly. =
Then
the color of the midpoint of each edge is the average of the colors of =
the
endpoints plus a random variable (presumably with mean zero) times the
length of the edge. The color of the center is the average of the colors =
of
the edge midpoints. (Note that the color values are much more precise =
than
the actual palette, so as to allow them to be averaged and displaced
fairly.) I can't figure out what the new algorithm does.

Note: This algorithm is technically incorrect because it is stratified
along the dyadic grid (Mandelbrot FGN p258). A more realistic model of a
terrain can be obtained by adding Weierstrass functions projected along
various directions. Note, however, that there must be a large number of
such functions. Otherwise, a "striping" effect will be seen along these
directions.

Dave,

   a    b    c

   d    e    f

   g    h    i

Given this grid of points, with a, c, g, and i already defined, we want to
define the remaining points (b, d, e, f, h) in a way that generates fractal
terrain. What you suggested is to generate the edge points first, then the
center point. In fact, when I tried to adapt the triangular
midpoint-displacement algorithm to a square grid, I tried this too, but in
fact it's the wrong way to do it. You should generate the center point
first, then the edge points.

The problem with doing the edges first is that it increases the resolution
of the grid unevenly. When doing midpoint-displacement on a triangular
grid, you can increase resolution along each of your grid axes
independently; it doesn't matter what order you do them in. When you're
done, you have a new triangular grid with twice as many points. With a
square grid, though, you can't do it all in one step; you have to do it in
two. And if you do the edges first, you're generating one set of points by
averaging only two neighbors (the edges) and then another set of points by
averaging four neighbors (the centers). This doesn't look right.

By doing the centers first, you are doing two steps, but now they're
*equal*. The first pass does the centers; average the four corners, then
displace by some random amount. At the end of this intermediate step you
have a new, complete square grid at double the resolution of the previous
one--rotated forty-five degrees. Now you want to do the edges, but notice
with the new grid you get after doing the centers, the edge points that
still need to be done have become the centers of the new, forty-five degree
grid. So you repeat the process of averaging four corners for each new
point--but two of those corners will be new points created in the previous
step.

This makes each half-step totally equal and produces far better results. I
think FractInt does the edge points first, but I haven't checked the code
myself, so I can't be sure.

So we would start with this (where x,y are cartesian coordinates and p is
the color value at that point):

p(x1,y2) p(x,y2) p(x2,y2)

p(x1,y) p(x,y) p(x2,y)

p(x1,y1) p(x,y1) p(x2,y1)

And then generate the mid points between these lines as so:

p(x,y1) =3D [ p(x1,y1) + p(x2,y1) ] / 2
p(x1,y) =3D [ p(x1,y1) + p(x1,y2) ] / 2
p(x,y2) =3D [ p(x1,y2) + p(x2,y2) ] / 2
p(x2,y) =3D [ p(x2,y1) + p(x2,y2) ] / 2

Then each edge point gets modified up or down by a random amount.  The me=

midpoint by the length of the edge:

p(x,y1) =3D [ p(x,y1) + rand(10 to -10) ] * [ x2 - x1 ]
p(x1,y) =3D [ p(x1,y) + rand(10 to -10) ] * [ y2 - y1 ]
p(x,y2) =3D [ p(x,y2) + rand(10 to -10) ] * [ x2 - x1 ]
p(x2,y) =3D [ p(x2,y) + rand(10 to -10) ] * [ y2 - y1 ]

Then the center point:

p(x,y) =3D [ p(x,y1) + p(x1,y) + p(x,y2) + p(x2,y) ] / 4

Dave,

 - What do you do about the points on the outside of the field that only
 - have three legal neighbors?

You can either average only three ways, wrap, or "reflect" and use a legal
neighbor more than once.

 - How much random displacement would you use?

Each full step should have half the displacement range of the previous full
step.  This means each half-step should have 1/sqrt(2) the range of the
previous half-step.

 - What language was Fractint written in?

C and x86 assembly.

This is what I'm starting to see for the center point.  Please correct me.

    p(x,y) = [ p(x1,y1) + p(x1,y2) + p(x2,y1) + p(x2,y2) ] / 4
    p(x,y) = p(x,y) + rand(weight to -weight)

Then, for recursion, weight is multiplied by 1/sqrt(2).

Dave,

No correction necessary, this is precisely right. This is the first half-step.

 - Then, for recursion, weight is multiplied by 1/sqrt(2).

Right.

What you do when you hit 0 or 255 is up to you. Personally, I would
generate the entire thing at 16- or 32-bit precision, then check for the
lower and upper bounds and scale/offset accordingly. You could also just
clip intermediate values, or wrap. Wrapping is, of course, bad. :)

This approach starts with a square, then moves onto a diamond, then back to
a square (a smaller one than the first).  From the first square to the
diamond, weight is multiplied by 1/sqrt(2).  Does multiplying weight by
1/sqrt(2) a second time equate to weight/2?  I'm just double-checking my
math here.

Dave,

Right.

What you do when you hit 0 or 255 is up to you. Personally, I would
generate the entire thing at 16- or 32-bit precision, then check for the
lower and upper bounds and scale/offset accordingly. You could also just
clip intermediate values, or wrap. Wrapping is, of course, bad. :)

You import the PAR. There are a very few things which are not importable,
but most things come in fine.

Ultra Fractal is not a complete replacement for FractInt. It doesn't do IFS
fractals, it doesn't do any strange attractors... just escape-time
fractals, like Mandelbrot, Phoenix, and anything from the formula parser.

Date: 14 Jan 1999 10:52:03 +1100

Hi everyone...

For my first post to this list I'd like to ask for help with a little
probelm I'm having.

It's sort of Fractint related--I'm writing a program for creating and
editing colour maps. One feature will be to generate palettes with
waveforms, but I'm really bad at maths.

To create a sine wave I use:

amp*sin(freq*time+phase),

and I stumbled upon a square wave as:

amp*sign(sin(freq*time+phase)).

Can anyone suggest equivalent fomulas for generating sawtooth and triangle
waves?

If I get this program finished I can get around to actually playing with
fractals.

Thank you.

Mark Townsend

You can generate a sawtooth wave using the mod() function:

y=amp*mod(freq*x)

will give a y wave that linearly ramps from 0 to amp, then drops
immediately back to 0.  Changing freq controls the width of the ramp.

Thanks for the suggestion, Kerry. That's basically what I've been using for
ramps, but I wanted to create waves at the same frequency and phase as the
sine wave. I seem to have the sawtooth worked out now--with the
serendipitous use of Pi and the fact that the byte data type automatically
clocks to zero when you increment it too high.

Dear All,

I've just finished writing a Perl script that reads par files and
generates batch files, just as partobat does.  However, unlike partobat I
can run it on my Linux system with xfractint (the Unix port of fractint).
It should also work on dos based systems (that support perl) but I've not
tested on such systems.  If anybody would like a copy, please drop me a

my be freely used and passed on.

From Kerry Mitchell's formula, you could put
if(amp>.5) amp=3D1-amp
to make a triangular wave.

Note that Kerry Mitchell's sawtooth ranges from 0 to 1. This triangular
wave ranges from 0 to .5.

Thanks. I'm still working on it. Kerry's reply got me thinking--I should
modify the sine wave formula to fit the ramp and triangle, rather than the
other way around. After a bit more research I discovered how to make a sine
wave with a frequency of 1 fit the range of the map exactly, and that makes
it easier to scale the frequencies of the other waves. The hardest part
seems to be getting the waveform's phases to match.

not listed among them. When Sylvie Gallet found this out, she never
bothered to tell me how I can get around this problem. Could someone who
knows about C and Assembly please tell me how I can modify the source cod=

Please don't think the answer will be too complicated for me.

All I get is lots of shades of blue and green. The video mode entries
don't seem to say how many colours you get in these modes, they just
say things like "15k", which means nothing to me.

On a slightly different note, would it be possible to create a disk
video mode using more than 256 colours just be editing FRACTINT.CFG?
Sorry, I'm just greedy like that!

The current version of Fractint has a very minimal amount of true-color support;
you can use one of the true color video modes, but palettes in Fractint are
still limited to 256 colors, so when you view a fractal in one of these modes,
you see 256 slightly different shades of blue and green.  The "15k" is a
notation that makes use of the metric system, and means "fifteen thousand"
colors.

>video mode using more than 256 colours just be editing FRACTINT.CFG?
>Sorry, I'm just greedy like that!

I believe so, but the results in Fractint would be similar... you must save the
images and re-color them in another software, or better yet, save the .par for
your fractal and load it into Ultra Fractal, which has good true-color support.
The URL where you can find Ultra Fractal escapes me at the time... sorry!

Hi all.

These are my first attempts on fractals. They're rather naive, but I'm st=
ill
trying to understand how come if you see that colored default palette it
won't be that colored at all by using another
one (I mean having different colors, not a quasi-continuum color). And I
still don't know how to get that 3d smooth quality that some of the fract=
als
I saw do have.

The Yellow Snow resembles to me Nanook, the Frozen Eskimo, eating some
doggie snow. But I know it seems like one of the snakes you can find at t=
he
beginning of Out of this world, if you know what I'm talking about. FZ,
please forgive me.

The Blue Pulsar, began as a vain attempt on having some flowers out of th=
e
A0 formula. In some part of the original drawing you can see a kind of
garden. But for some reason it didn't get the right colors. Instead it
seemed like a skeleton and I disliked it. But looking at the garden I cou=
ld
see a starlike form. Then I zoomed the star and again had the same proble=
m
by trying to color it. I wanted a Black Star, not a Blue Pulsar, but the
latter won.

The Fire Spear is like a ray emerging from a volcano. I liked the colors =
in
it, though it has nothing special.

Train to Mars is based on a magnetic fractal. I liked the colors too, and
the image of Mars shining above the railways.

Talking about names, of course the first one is named after Frank Zappa's
Don't Eat The Yellow Snow song. And the Pulsar is the first name I grabbe=

That's not a very original name, but I was in a hurry when I named it. I
like the glossy effect in some areas of the image and the feeling of depth
in other areas. The bridge-like structures seem quite solid, yet
paradoxically, delicate.

Enjoy.

Date: 19 Jan 1999 20:21:50 EST

There are two ways:

1:  for color maps already in existence  ( many are available at many of the
fractint support links), you simply hit "C" for color and "L" for list, and
select one of the available color maps.  If the first one is not satisfactory,
then hit "L" again, and the list comes back.  When  you find one you like, you
will notice the border is lighter color- hit escape and you will be back in
fractint with full menu availability

2:  The other way is to design them yourself.
hit "E" and you will see a ghosted box.  Move it to where you can view your
fractal and hit enter.  This brings up your color pallett.  Move the cursor
into the area and select the colors you wish to edit.  Reading the help files
on pallette manipulation will help you here tremendously.

Paul,

I have missed your postings lately. Having started working with Ultra
Fractal a short time ago, the first formula I worked with in it was my
old favorite, your Zf_Ang. I have replaced the images on my old Zf_Ang
page at my Geocities website with these true color images. I thought you
might like to see them. Thanks for your fine formula!

Fabio--

With your image loaded (or even while it's still loading), press "C",
then press "L".  This will allow you to load any colormap in the
Fractint directory.  You can cycle the colors by pressing "C" again, and
stop cycling by pressing "C" yet again.  The "<" and ">" keys change the
cycling direction.  Once you have the look you want, press "ESC" to get
back to normal Fractint operations.  I hope this is clear; I change and
cycle colors without really hinking about the steps...

Hi everyone.
I found the address of Lee Crocker, the author of the Decomposition coloring
method on Fractint's cerdits screen.
I've sent the message below to that address but the author could not be
reached thatways.
So I am hoping that he'll read this message.
Also, if anyone else knows the answer, it would be nice to read it.
Once my project is built, be sure it will be a good source of unusual
"geneticaly engeineered" formulas.

Thanks in advance.

Subject: (fractint) Re: Decomposition
Date: 20 Jan 1999 19:43:00 -0500

I would assume that the way this is done is by repeatedly squaring the
value from the final iteration. A binary number would be built up from le=
ft
to right. The first (leftmost) bit would be one when the final iteration
has a negative real part or zero when the final iteration has a positive
real part. The second bit would be determined the same way from the squar=
e
of the final iteration; the third, from the fourth power of the final
iteration; etc.

If any of these values has a zero real part, it would be grouped with
either the positive or negative real parts; it's up to you. However, you
would have to be consistent.

Note: I haven't actually checked the source code on this. It just seems t=
he
sensible way decomposition would be done. If someone knows a mistake in
this algorithm, please let both of us know.

Collin,

Actually I'd expect the decomposition to simply be read off from the angle
directly. You could keep squaring the number, but if you don't add c each
time this has precisely the same effect, but it also increases the
magnitude of the number substantially each time, and if your bailout is set
too high you will overflow.

That's my understanding, too.  Setting "decomp=n" will cause Fractint to
color the image by breaking the final polar angle into n segments.  Binary
decomposition would come from setting decomp=2.  Then, all the angles from
0 to pi would be rendered in one color, and pi to 2*pi in another.

To draw a fractal with binary decomposition, e.i. decomp="n":

  1. Do the usual calculation for the pixel colour exactly as normal.
  2. Instead of using the iteration count for the colour value...
    a) Work out the imaginary part of the final value of Z (or
whatever) divided by the real part.
    b) Take the arc-tangent of this value.
    c) You now have an angle (radians!) between +Pi and -Pi.
    d) Split that range into "n" intervals, and see which interval
contains your angle. The number of this interval is than the pixel
colour.

Simple.

Subject: (fractint) Set Union
Date: 21 Jan 1999 11:23:37 GMT

I'm working with the formula (Z^3) - 3(A^2)Z + B, which is
(apparently) a generalization of all possible 3rd degree polynomials.
I've got Julia sets working fine, but I'm having trouble with the M
set. You see, with the good old quadratic M you must iterate one
point, zero, and see where that goes. However, for this Cubic M,
there are two points to worry about, +A and -A. So there are two M
sets, M+ and M-. I've got formulas for these working just fine, but M
itself is the Union of M+ and M-. How do I do that in FractInt?

P.S. For anyone interested, you can do these Julias with

CubicJulia = {
  A = p1,
  B = p2,
  T = 3*A*A,
  Z = Pixel:
    Z = Z*Z*Z - T*Z + B,
  |Z| < 4
}

For anyone wanting to see the M set (or M+ or M-), there's an
additional problem: they're 4-dimensional!!! I can do slices parallel
to the "A" plane of the "B" plane (B looks best). For example

CubicMandelbrotBP = {
  A = p1,
  B = Pixel,
  T = 3*A*A,
  Z = A:
    Z = Z*Z*Z - T*Z + B,
  |Z| < 4
}

That gives you M+ in the B plane. To change it to the M- set, change
"Z=A" to "Z=-A". To change to the "A" plane, replace "A=p1" with
"A=Pixel" and replace "B=Pixel" with "B=p1".

P.P.S Yes, I *KNOW* that M+ and M- are symmetrical.

O.K., I've solved it. I've managed to find a quick work arround. If
you use two orbit variables, X and Y, and initalize them to +A and -A
respectivly, then run them both though the normal iteration formula,
then at the end of each iteration assign the one with the highest
magnitude to be the value of Z, then use |Z| < 4 as your bailout.
Behold:

CubicMandelbrotB = {
  A = p1,
  B = Pixel,
  T = 3*A*A,
  X = A,
  Y =-A,
    X = X*X*X - T*X + B,
    Y = Y*Y*Y - T*Y + B,
    if(|X|>|Y|)
      Z=X
    else
      Z=Y
    endif
  |Z| < 4
}

By reversing the ">" in the if() to an "<" you can do intersection
instead. So this method works, but it's sssssllooooowwww. If anyone
has a faster idea I'd just love to hear it.

I know that maybe it's nonsense, but have you tried putting A^2 and X^3 and
Y^3 instead of A*A and X*X*X and Y*Y*Y?. Maybe the formula parser process it
faster if it doesn't have to work with three or two variables at the same

I've created images for this type of fractal by superimposing images for
both critical points. I even have Fractint formulas to generate such
images; they use color ranges to color various areas...

Not at all--exponentiation is a very expensive process, but multiplication

The expansion of (a+bi)^2 is (a^2-b^2)+2abi. If this were done with regul=
ar
multiplication, you would multiply a by a, multiply b by b, and then
subtract. However, a faster way to do this, which Sqr probably takes
advantage of, is to factor the real part as (a+b)(a-b). This would give y=
ou
one addition, one subtraction, and one multiplication. Since addition is
cheaper (faster) than multiplication, this is probably how Sqr(z) can be
faster than z*z. Note that this shortcut works only when the two complex
factors are equal, so it couldn't be programmed into the regular
multiplication operation.

PS: Yes, of course, repeated squaring would cause overflow; I should have=

realized that. However, an easy way to avoid this would be to halve each
square until it is within a certain "safety zone." I think this would be
faster than computing the arctangent.

Collin,

 - regular multiplication, you would multiply a by a, multiply b by b,

Actually, the differences in cost between multiplication and addition are
almost negligible on a Pentium, and still minor on a Pentium-II. Unless you
are doing assembly programming, you might as well totally ignore the
difference and treat them as equal (at least for floating-point work;
integers are another matter). And when you DO get to the floating-point
level, other considerations come into play, such as pipelining, register
availability, etc. I actually found in several cases it's faster to skip
this "optimization" entirely and use a^2-b^2, especially if you need
a^2+b^2 for bailout (as you do for the M-set and J-sets).

For architectures where multiplication is still expensive (80x486 and
earlier; 680x0; others, no doubt) this optimization makes more sense.

 - PS: Yes, of course, repeated squaring would cause overflow; I should

Not so much as you'd think. Figure at least ten cycles per bit for the
squaring method, versus 35 to 150 cycles for directly computing the
arctangent (on a Pentium). You can get eight bits in eighty cycles, which
is faster than arctangent in some cases. If you need more bits, you might
as well compute it directly. And don't forget, you only do this calculation
once per point, not once per iteration; this makes optimizing it
considerably less important.

sqr(A) returns the same result as A*A, of course. But as Collin points out,
it is slightly faster because the calculation can be optimized a bit. The
FractInt parser only parses the formula once, it doesn't parse it over and
over. So the cost of parsing sqr(A) versus A*A is only incurred once.

No, the parser doesn't change sqr(x) into x*x and reparse it...
it parses x*y where x=a+bi and y=c+di as (ac-bd) + (bc+ad)i, four fmuls and
an fadd and fsub. (It doesn't care whether y=x in particular so x*x is
still four fmuls...)
It parses sqr(x) into (a+b)(a-b) + 2abi, which is two fmuls and two fadds
and a fsub. (The 2ab is one fmul and a fadd since, assuming Tim Wegener
wasn't drunk or deranged on the day he wrote that particular line of code,
he has it actually work as ab + ab, since the add is less expensive than
another multiply.)

Since multiplies are the main contributors to cycle-eating in mathematical
iterations, we highlight this as follows: x*x causes four multiples and
sqr(x) only two. sqr(x) may be as much as twice as fast depending on how
much more expensive fmuls are than fadds. This might depend on your
processor of course...

Yeh, it is nonsense. If you read the documents (I can't remember

strongly warn *against* using, e.g. Q^5, and say that Q*Q*Q*Q*Q is
raster (about 4 times faster in my experience). The reason is that
the "^" operator is designed to work with complex number powers as

This is correct. If the power is a real integer constant -1, 0, 1, or 2,
the parser recognizes this and does not run the power function ("^"), but=

instead runs recip, one, ident, or sqr respectively. Any other power,

      fld          st(0)               ; x x y
      fld          st(0)               ; x x x y
      fmul         st,st(3)            ; xy x x y
      fadd         st,st               ; 2xy x x y
      fxch         st(3)               ; y x x 2xy
      fadd         st(2),st            ; y x x+y 2xy
      fsubp        st(1),st            ; x-y x+y 2xy
      fmulp        st(1),st            ; xx-yy 2xy

It's OK, I'm dealing with it :-) there have been a number of people
interested in turning the chaotic orbits of  fractal caculation into music
of some sort, and since most modern sound cards include
comprehensive wavetable support I guess folks just want their favorite
program to use their new hardware :-)

Cheers,

Thank you, George, but I didn't write that. It was Andrew's writing. By the
way, Andrew, did you solve your problem? Because it seems that my "little

Yeh, it is nonsense. If you read the documents (I can't remember
exactly where it says so) you'll see that the FractInt authors
strongly warn *against* using, e.g. Q^5, and say that Q*Q*Q*Q*Q is
faster (about 4 times faster in my experience). The reason is that
the "^" operator is designed to work with complex number powers as
well...

This is correct. If the power is a real integer constant -1, 0, 1, or 2,
the parser recognizes this and does not run the power function ("^"), but
instead runs recip, one, ident, or sqr respectively. Any other power,
whether real, imaginary or complex, runs the power function, which is one
of the slowest in the arsenal. Thus real postive integers greater than two
are likely to run much faster if expressed as multiplication rather than
power, e.g. X*X*X is better than x^3.

Subject: (fractint) Simply Elegant and a question
Date: 22 Jan 1999 17:34:15 -0700

In a recent newsletter, I learned something interesting.

"That under orthodox Jewish law, the word "God" cannot be destroyed.
You can't, for example, throw away a piece of paper with the word=20
God on it--instead you have to ritually bury it or arrange for its
storage. The inevitable question arose over what to do when computers
are
involved: can you erase the word from a word processing document or from
some other digital form?=20

Last week, one of the leading orthodox rabbis, Rabbi Moshe Shaul Klein,
decided that it was OK to erase or delete digital versions of the word
"God," because they did not contain the actual word, but a composition
of 1s and 0s. If everything is binary underneath, the rabbi reasoned,
then even the word "God" is not actually G-o-d but a series of
numbers."--Alice Hill

Okay, so if everything is binary, including fractals, I guess that means
that they don't really exist. Just a bunch of 1's and 0's.  But we all
know that fractals exist, since we spend a lot of time creating them and
coloring them. :)  Now my questions is--when did fractals first exist?
With the invention of the computer, or did they exist but we were unable
to perceive them? Jim Muth asked where do fractals go when the power
fails. Do they continue to exist or is it really our power of perception
that is lost with the loss of electricity? If they exist only while on
the screen, are we guilty of murder every time we change screens?=20

Sorry about my rambling, but it has been too long since Jim has had a
good philosophical post. To make up for my rambling, here is a PAR.
Instead of seeking infinite detail and a fancy coloring algorithms, this
one is "Simply Elegant."

<<If they exist only while on

  Not any more than things out the window cease to exist when you close the
window. Fractals have been ingrained in the nature of mathematics ever since
God decreed that 1+1=2, so they're there, no matter what.

  Which brings up another point that I've been wondering about for some
time. If you've read Carl Sagan's novel Contact, the final scene involves
the discovery of a message from God ingrained in the nature of the universe,
specically in a deep decimal place in the value of pi, supposedly since God
would want to leave His signature in something universal and apparent to any
alien race anywhere in the universe. But the value of pi is ingrained in the
nature of the circle, which is geometric and not purely mathematical in
nature. It's concievable, although improbable, that an alien race could
exist with no concept of physical shape and thus be unaware of the existence
of the circle. Mathematics, however, is universal, and the process behind
fractal images is purely mathematical. Fractals can be shown to include
chaotic order and/or orderly chaos in both light and sound, and probably
would be able to in other human senses and in alien senses as well. So a
fractal seems like the perfect place for God to leave His "signature" in the
universe.

  Plus, pi was fairly well known to nearly every ancient civilization on the
planet, most of which were still fairly spiritual and faithful to their
god(s). (Even the Bible mentions pi at one point, though it just uses the
value of 3.) Fractals, however, cannot concievably be generated without the
aid of computers. Computers by their nature are unlikely to be developed
except by a race which has succeeded in unlocking a large part of the
physical nature of the universe and is beginning to doubt its faith in God.
If I were God, I'd want to place My signature at exactly the point where a
race with growing science and atheism would find it and reaffirm their faith
in a higher power. Fractals seem perfect for this purpose.

Well, the reason Ultra Fractal doesn't like them has nothing to do with
them being PHC formulas (UF handles those fine) but is because this formula
writes a value to "pixel", which in UF is not permitted. I was able to
rewrite Carr3386 to work, but I can't get 3385 to work yet.

A quick look at the formula indicates you are only writing to pixel so as
to enforce horizontal symmetry, which you only need to do in the formula
(instead of by using the symmetry feature in FractInt) because it's a PHC
formula and using built-in symmetry would produce a break in the dither
pattern at the symmetry seam. The idea behind the PHC method is to
composite two fractal shapes, at a 50/50 mix. Ultra Fractal supports this
more effectively through layering, which can take advantage of 24-bit color
and eliminate the PHC dithering. And, you get to pick more than just a
50/50 mix. Layering is like PHC, much the way a Saturn V rocket is like a
firecracker. :-)

Ah, but geometry is one aspect of mathematics, and pi has many
applications in other aspects of mathematics.  For example, if you have a
set of horizontal lines on a piece of paper on a tabletop, and you drop a
toothpick onto the paper, the probability that the toothpick will cross a
line is related to pi.  Also, pi can be found in the Mandelbrot set, in
terms of the relationship between the number of iterations to escape and
the distance of the point from the edge of the set.

I wouldn't go that far.  Fractals (not called that, of course) were know
to mathematicians of many years ago.  For example, Gaston Julia of Julia
set fame (1800's ?) and David Hilbert, of Hilbert curve fame (early
1900's).  Most mathematicians didn't quite know what to do with them
(maybe something like Pythagoras not knowing how to handle irrational
numbers), but they were certainly known.

Also, don't underestimate the computational power of a society without
cable tv.  Log and trig tables to n decimal places have been around for
hundreds of years, as has many decimal places of pi.  Since the
fundamental calculation involved in fractal generation is simple, most
cultures could probably do it, should they choose to.  A great deal of
calculation has been accomplished by dedicated individuals with very
little in the way of (modern) technology.  In fact, the first "computers"
were people, not machines, who calculated such things as projectile
trajectories.

Fractals, in the guise of natural objects, have been around forever, so
it's not inconceivable that non-electronic cultures are making them.

<<I wouldn't go that far.  Fractals (not called that, of course) were know
to mathematicians of many years ago.  For example, Gaston Julia of Julia
set fame (1800's ?) and David Hilbert, of Hilbert curve fame (early
1900's).  Most mathematicians didn't quite know what to do with them
(maybe something like Pythagoras not knowing how to handle irrational

hundreds of years, as has many decimal places of pi.  Since the
fundamental calculation involved in fractal generation is simple, most
cultures could probably do it, should they choose to.  A great deal of
calculation has been accomplished by dedicated individuals with very
little in the way of (modern) technology.  In fact, the first "computers"
were people, not machines, who calculated such things as projectile
trajectories.>>

  Agreed, you could calculate fractals by hand, but it would take a whole
lot of scratch paper and a very bored mathematician. And computers make it
far easier to actually explore the full complexity of the M-set and others.

I know some people have linked Fractals and God's existence, but I'd guess
this sort of thing might not appeal to as many subscribers as more "down to
earth" Fractal topics ;)

There's no problem with the chat that's been going on so far, but I just
thought I'd suggest it wasn't taken too far - before someone gets cross and
fills our mail boxes with angry rubbish (you know the sort that need only
the slightest hint of religion before releasing their "strong opinions").

Don't forget though, I'm not saying anything that has been said so far is
particularly unreasonable for this group (most of the stuff has been
relevant to Fractals) - but just a warning to start changing/ending the
topic (from previous experience with the for and against God arguments!)...

Yes they have!  The connection might or might not be valid, but
isn't it curious that the abstraction of fractal math can be

abstract idea some call God?

Yes it might not!  As a result, I suggest we stay "down to earth"
and limit our search to the fractal dirt instead of aspiring to
the fractal stars.  :-(

That's because it hasn't gone anywhere yet.

You are right.  Mankind has not yet reached the stage of maturity
where he can intelligently and unemotionally discuss such important
non-objective topics as religion and the philosophy of science.

So let's stick to objectively real things such as fractals.

But are fractals "real"? Intuitively, something isn't real unless I can
touch it, smell it, or taste it. Yes, I can see an image of a fractal,
but is this the real fractal itself or an artifact of 1's and 0's?
Consider a fractal that is viewed at F3 and the "exact" same fractal
viewed at SF3. They look different. Are they the same fractal or just a
different arrangement of bits?

Xylen,

Not true. These are *physical* aspects. Is love real? How about hate?
Fractals are as "real" as any other abstract concept. Arguing whether
fractals are "real" seems rather silly to me, an excuse to sound
philosophical. :-) The very definition of "abstract" is "considered apart
from concrete existence".

 - Consider a fractal that is viewed at F3 and the "exact" same fractal
 - viewed at SF3. They look different. Are they the same fractal or just
 - a different arrangement of bits?

They are two approximations of the same abstract object. Although we can
never achieve a precise physical representation of the object, that doesn't
mean the abstract object "does not exist".

You err in _assuming_ you have a right to free speech on this mailing list.
Tim is the list administrator; he is within his rights to squelch any
discussion at any time, ultimately by removing the participants from the
subscriber list if necessary. That he generally lets the discussion wander
where it will, without too much restriction, is our good fortune in having
such a benevolent moderator. And ultimately, since this list is run on
Xmission's servers, they have the option of suspending the entire list if
they so choose.

We have freedom in this forum to discuss what we want, subject to the
overriding decisions of Tim and Xmission. (Although I don't think Xmission
monitors the list.) So while you have the freedom to say what you want, you
don't necessarily have the freedom to use this forum to do it. If you don't
like the forum, you have the freedom to set up your own.

PLEASE NOTE: I'm not saying Tim will censor us! I'm not saying he should or
shouldn't! I'm just saying that before we rally behind the cry of "free
speech" we should understand what we're really getting into. I've read the
discussion with interest, even though I don't necessarily agree with the
participants.

Nice thought, except for a few problems. First, you instantly *double* the
mail load on the Internet. This is a bad idea; the net is already heavily
loaded. :) Second, you double the amount of mail everybody receives. Third,
what about mailing lists like this one? If I post a message to this list,
should I receive "your message was read on Thursday" notices from every one
of the hundreds of subscribers? Please, no.

Oh, and you might want to refrain from using HTML-formatted mail when
posting to a mailing list. There are still quite a few situations where it
renders your mail totally unreadable.

Hi folks.
Fractals and music is an interesting topic and there are some serious attemps
there (I know some Germans and some US Americans) to make the orbits audible
and to get these series of notes into something like a piece. As I don't have
the URLs at hand, please let'em serach with "fractal music" and you'll get a
real lot valuable stuff.
What I am interested in is a way to transform linear fractals into waveforms
to beplayed by a soundcard. If anyone would like to communicate on that,
please email me. Thank you.
And many thanks to all the contributors who made my screen glow in ever

Darn tootin I can and will squelch discussion and boot list

My only concern is that this list be useful for the members. That
means keeping reasonably on topic. The reason for this is that the
traffic is high, and the more off topic messages there are, the less
useful the list is for it's intended purpose. Otherwise I see little
reason to use a heavy hand to try to control what list members
write. Over the life of the list there has been very little trouble. From
time to time I have nudged folks to stay on topic.

The topic is fractals and fractint. It can wander a bit into related
topics such as philosophy or computer issues related to fractal
images.

Everybody should be clear that there is no "free speech" on this
list. The list is for discussion of fractals and fractint, and not other
subjects. But quite frankly we are all mature folks here and
policing on my part is unnecessary and won't happen without good
cause. I expect everybody understands why the list has the most
utility if we stay on topic.

FWIW I hereby declare mail bombing etc. as off topic. This should
be obvious to everybody. If folks want to talk about philosophy or
religion with regard to fractals, that is OK with me, within the limits
of what is of interest to most list members. I would ask that anyone
who posts a message on any subject do a sanilty check on
themselves and make sure sure their posting has a reasonable
chance of being of interest to many of the list members. Postings
of limited general interest should go as emails to specific folks you
know are interested.

Precisely correct!  My sentence is intentional irony.
Mankind constantly handles abstract concepts that are not
"real" in the physical sense, yet most certainly do exist.
If we give these concepts names such as: "love", "honor",
or "fractals", there is no contention.  It is only when we
begin applying names such as "God", "Heaven", or "the human
soul that survives death" to our abstract concepts that the
contention arises.  Why are mere labels so important?

There obviously is a connection between the idea of fractals
and the idea of God, since both are abstractions.  But I
don't feel that this list is the place to discuss the topic.
Maybe we need a separate mailing list to discuss the
philosophical aspect of fractals.  But if fractals had no
philosophical aspect, I would have grown tired of them 10
years ago.

I heartily agree with you on the philosophical aspects of fractals. I
can't look at a fractal without trying to understand it and anything it
may represent. This goes beyond just trying to title a fractal.=20

Your FOTD essays have generated a lot of philosophical discussions,
including subjects like  GOD, reality, and their relationship to
fractals. There also seems to be several people that like to comment on
or just read the discussion on these ideas. I wonder if it would be
possible to talk Tim into creating another mailing list, or perhaps
somebody else has an idea on where such a mailing list could be created.

I don't know about others, but some fractals really are interesting, while
others are not the slightest bit interesting at all... at first I thought it
might be the color maps, then I realized it was more the intricacy and
complexity vs the simplicity.   Hard to explain, but some fractals 'have it'
and some 'don't'.

I can create such a list, if there is interest. I thought about whether

don't think it is. I'm not sure another list will survive long, once the
current surge of interest dies, but I don't have any objections to setting
up the list if someone else wants to actually administer it. (i.e. deal
with unsubscribing people whose addresses fail, etc--and of course keeping
the discussion on topic and squelching nuisances. :)

I also fear that a fractal philosophy list would come on with a
burst of activity and then die a lingering death.  Tim seems
willing to admit the topic of fractal philosophy onto this list
-- as long as we don't start fighting among ourselves.  What we
want to avoid is the anger that so often arises whenever matters
of religion and Atheism are discussed.  Unfortunately, in my
experience, this is nearly impossible to do.

See you in the FOTD.

Sure they could, although it could well take hundreds of
years to generate one. But humanity has completed other
projects which took hundreds of years, such as building
cathedrals. In fact, you could say that building present

Usually I post related pars but this time I feel like posting images that

The Spines par is in a series of plastic, rounded forms. Gradual changes in
the color map produce highlights and muted depths.

The river view series of pars is something I have just started to wander

After all, _all_ of these experiences (fractals, tastes, hate and so on),
are the outcome (somehow) of the working of our brains. All of them have
the same physical existence as variations in the electrical and chemical
dynamics of the subject's brain.

Thing is, there's only so much brainpower to go round in any given person
(some more than others, but still: what you've got is what you've got). So
how are fractals treated by the brain? When you're contemplating a fractal,
are the parts of your brain that are the most active the same as or working
with parts that respond particularly to music? Vision? Trees? The concept
of God? Modern brain scanning techniques may well put some meat on what is
here just a stick-figure idea.

It may be that fractals have such a profound effect on so many people with
all sorts of outlooks on life has something to do with our brains just
happening to be wired up to appreciate them? Not because they're fractals,
but because they're so much like (neurologically speaking) things we're
already bred to find fascinating?

And if so, what guarantee would we have that another intelligence (aliens,
for short) would find the things at all interesting?

Morgan

Anybody had problems running ParToBat from Windows 98?

Last night I simply could not get it to work - not from Windows, from the
Windows DOS prompt or after  rebooting to DOS and trying it from various
directories.  All I could ever get was "Runtime error 200 @ 0356:0091" -
whatever I tried.

Tonight no problems - same files, same directories???

Gremlins.

Wayne

BTW    I'm impressed with the way '98 handles video mapping.  I can now generate
            images in SF7 mode and swap back and forth to other programs and not
            have a garbled Fractint screen when I return.  Saves generating them
            in Video Mode and converting back to SF7 later.

You probably need the new version of partobat (v3.5), designed to run on very
fast machines. You can get a copy from Jo Weber's page at:

I would like to see such a list created; one where the long-winded nature of
fractal philosophy discussions could reach its potential.  As far as the current
interest in this thread dwindling, I suspect the list traffic would surge and
calm as most lists do, but at least the list would be there for the surges; it
would also give individuals interested in philosophy, but not so much in the
workings of Fractint, a fractal-related list they might like to subscribe to.
Hopefully, Jim Muth would post his FOTD there, providing a minimum of traffic
and philosophy at all times!

Subject: Re: (fractint) Spines and rivers
Date: 24 Jan 1999 15:18:26 -0500

The other day I posted a par (reposted below) that reminded me of views of
a river country. Since then I've found a few more that please me. I like
the gray and tan areas that remind me of sandy soil. The neat rows that
seem to be orchards or vineyards. Dark lakes and meandering waterways and
roads.

This series has been instructive in learning another Fractint tool. The
initial view of each of the fractals was flat and (if you think of them as
landscapes) from directly overhead. With some experimenting with the
x-magnification parameter, I was able to create views that were more akin
to views from less lofty heights; from scenic overlooks if you will. (Type
z, F6 to get to the screen with x-mag. If you rotate the image you will
probably want to type z, F6, F4 to reset the x-mag.)

This sort of mailing list is a natural for

Actually, I've heard an explanation of the verse in question that showed

the actual value of Pi.  Unfortunately, I cannot recall the details well
enough to present them here.  Should anyone be interested in specific

Inspired by an ongoing challenge at the Ultrafractal list for gray scale
images, I added a page of black and white fractals to my Geocities web
site. I hope you enjoy your visit.

If you visited my site recently, the old version may still be in your
cache. Please hit reload button to make sure you are getting the updated
version. I made some extensive changes on many of the pages. Thanks.

Two questions:

Where did you get the word Riparian? Is this a Star Trek word?

According to the Fractint manual, "LOGMODE=fly/table Forces the use of the
on-the-fly routine or the logarithm table for the calculation of log
palettes.  Not normally needed."

Goodness knows where I picked it up. Must have been in someone else's par I
extracted from the list. I removed it from one of the riparian pars and did
not see any difference in the image or speed of computaion.

Riparian means river bank or estuary. As for SciFi, this applies more to
Philip Jose Farmer's Riverworld stories (where I first ran across the word)
than to Star Trek.

Bill Decker

A couple more odd pars.

oops, was cut off mid sentence.....

Water bank or shore line... usually or most commonly in the legal term, such
as "riparian rights"

How can I execute Xfractint with the batch option in the background (using the command line), I mean without having the Xfractint window opened.

Well folks, here it is. The Philosophical-Fractal mailing list is
finally up and running. Thanks to Damien for doing the hard part.  :)

This mailing list is for the discussion of fractal philosophy. This
includes science and religion, at least in their non-dogmatic aspects,
and the way they relate to fractals. This list will have broader limits
than the three current fractal lists. The new list is the place for
discussions that are fractal related yet don't fit into the current
lists. But this is not an "anything goes" policy.  Any attempt to
promote an agenda, such as converting to Christianity or debunking the
paranormal will not be allowed. This is how arguments start.  We must
remember that one person's nonsense is another person's truth, and all
opinions are worth a consideration. What we want is a free exchange and
blending of fractal and philosophical ideas.

This list is closed and unmoderated. This means that only subscribers to
the list can post messages, and all the messages you post go out to
subscribers without advance checking by the administrator. Although I do
reserve the right to warn, and if necessary, remove posters who become
belligerent, use foul language, or in any other way are abusive in their
posts.

You can subscribe by sending a message to [e-mail]
with the words "subscribe philofractal" in the body of the email (please
remove the quotes when you send the message). If you have any questions
about the list you can reach me at [e-mail]

Try

xfractint -disk

This is a sort of disk video mode, and it works without Xwindows.

Recently my housemate, Blade, has been playing with XFractint on his
Irix-running Indy.  I forwarded him Tim's reply 'cause he was having
trouble generating large fractals to video.  He replied with this, which
is pretty obvious if you read the README (which he didn't, and hence
spent a few futile hours trying to fix a non-existant bug!), but who
knows, maybe it'll help..

_______________________________________________
Hi,

You may want to mention the "-private" flag to enable all 256 colors.

It is also necessary (desired) to specift the inage resolution with that
-disk option.

example:

xfractint -disk -geometry 1024x768

<color><param>0100,0100,0100</param>Folks, no more messages about viruses, real or otherwise on this
list, which is about fractals. Also, when you chastise a foolish list
member for posting something off topic, unfortunately you
exacerbate the problem if you post it on the list. Send the mail
privately. I have written Barry an email about his off topic post, and
I want to see no more discussion about this on the list.


I don't even want to see any "right on" messages in response to
THIS message, I already KNOW I'm "right on" :-)


Thanks, I'm sure with a moment's thought you all see the point.
This list is for fdiscussion about fractals. Messages on any other
topic, even topics of weighty import, reduces the usefulness of this
list.


Thanks to everyone for generally following this quite well, with the
occasional lapses that annoy us all.

Thanks for this job! It's a good idea! I'm now motivated to experience
formulas this way...

I think, I gonna set the:  width = real(scrnmax/imag(p3))


and the :  x = trunc(real(scrnpix)/width + 0.5) to

           x = round(real(scrnpix)

so the     y = trunc(imag(scrnmax - scrnpix)/width/0.75) to

           y = round(imag(scrnmax - scrnpix)/width/imag(p3))

... with the old "try and error" methode.. (I'm a mathematically a simple "0")

  Hi Folks,

   I just wanted to say that I'll always be a Fractint list member.  I notice
a bit of a migration towards UltraFractal as even myself have done, but
Fractint will always be King in my opinion. Although UF does some really fine
stuff with images, I prefer to search for them using Fractint first and then
fine tuning them with UF afterwards.

     Regards~

Subject: (fractint) Web Page Construction--Help!!  O/T?
Date: 30 Jan 1999 19:55:55 -0800 (PST)

Hi guys and gals,

I really need some suggestions on how to get a web page up without
having to learn all that html stuff.  I've got a good book for it, but
since I've been working I just don't have time to sit down and learn
it and do everything else I have to do in a day. Is there an easier
way to make a web page?  I just want something simple:  a front page
for a little write up and links to gallery pages and maybe a link
page.  The galleries I simply want to set up for maybe 16 thumb nails
to take you to the larger version of the fractal.

Can anyone offer me some suggestions?  I'm wanting to do another site
for some other creative work, but it's a little more complicated (I
think).  But I'd love to get my fractal site up.  :)

Thanks to any and all who can help me.
Debora

If you find a website that is similar to what you want to do for yours,
then you could just use the browser's FILE | SAVE_AS to get a copy of
the source HTML and modify it for your own.

Also, there are several products available on the market for webpage
creation (Freeware and Shareware).  Just download one from the various
"give-away" websites and have a go at learning that software.

Either way, you will have to learn something new.  But HTML is not hard
at all, and Notepad is the perfect editor.   :-)

Hi alltogether,

I would like to create large high res. Fractint Pictures with Fractint
19.6. My goal are 4096*2732 points 256colors. I didn't find an easier
way to create manually the
four 1024 * 768 pictures by evaluating the x-y-coordinates ba my own
hands.
And then putting them together in a pciture-edding-Program like Corel.

Does anybody has an idea to make this more efficient?

Yours sincerly,

Axel,

In fractint, hit "b" for the save pars screen.  Toward the bottom there
are places for you to specify x and y multiples.  If you put a "2" in
each, fractint will divide the screen in 4, 2 rows, 2 columns and save the
pars for the four images, together with a file called makemig.bat (IIRC).
When you run makemig.bat from the command prompt it will batch generate the
four images and piece them together into a multi-image gif file, and if you
remove the "rem" at the beginning of the next to last line of makemig.bat
(the line that refers to simplgif) it will convert the multi-image gif to
a straightforward gif (since many viewers don't handle multi-image gifs).
There is more in the fractint documentation.

You can use this technique to make images up to 64Kx64K, if you have the
machine to handle it.  Even for smaller images, it helps to have lots of
memory, as to make the simple gif image the machine needs enough memory
(or disk space) to hold 3 copies, uncompressed.

Sometimes there are problems at the edges of the component images,
particularly if you use a guessing method for drawing, so I usually use
the one pass method to avoid the problem.

One thing to remember is that by dividing up the images, you are
effectively zooming into the original.  You might need to up the interation
count in the original (or edit the pars, which are in fractint.par) and
you need to be careful when you are near the limits of fp math, as a zoom
my put you into arbitrary precision, and really slow things down.

Hope this helps (and isn't wrong - but I'm sure someone will set me
straight if it is).

Your close, Michael.  But there are a few steps that should be
clarified, I think.

I have a web page up that explains how to make high resolution prints in
Fractint.  You have to use makemig and simplgif both.

You can check it out at:

Hope that helps!

Hi there!
    I'm relatively new to fractals and I have a question about deep zooming.
I've been looking at a mandelfn(sin) fractal, and when I zoom fairly far
into it, the pixels stop being square and start being small vertical lines.
Is this normal?  Have I reached the effective limit of magnification or is
there some way around this?

Subject: (fractint) Unusual minibrot
Date: 31 Jan 1999 15:55:45 -0500

I have been exploring some formula variations of the Mandelbrot set in
which every other iteration is perturbed by another function. I came across
an unusual set of spirals around a minibrot which I thought looked neat.

========== The Formula =======================

multifract1 = { ; Ron Barnett, January 1999
   ; Use decomp = 256 or outside = atan
   ; Use imag(p3) to change the color spread
   zc = z = c = pixel
   IF ((real(p1)) == 0 && (imag(p1) == 0))
      p1 = (0,-0.5)
   ENDIF
   IF ((real(p2)) == 0 && (imag(p2) == 0))
      p2 = 1
   ENDIF
   IF (real(p3) == 0)
      p3 = p3 + (10000,0)
   ENDIF
   IF (imag(p3) == 0)
      p3 = p3 + (0,10)
   ENDIF
   choice = iterexp = 0:
   choice = (choice == 0)
   IF (choice == 0)
      zc = p2*(zc*zc + c)
      iterexp = iterexp + exp(-cabs(zc))
   ELSE
      z1 = exp(zc)
      z2 = sin(zc) + z1 - 1
      zc = zc - p1*z2/(cos(zc) + z1)
   ENDIF
   IF (|zc| > real(p3))
      smooth = iterexp*imag(p3)*pi/128
      ang = cos(smooth)+flip(sin(smooth))
      z = 256*ang
   ENDIF
   |zc| <= real(p3)
}

I think they continue to exist...
They have existed, and always will exist, quite independently of being
perceived.

They exist ephemerally and imperfectly when perceived.
But they POTENTIALLY exist, perfectly! (always have, and always shall).
It's rather analogous to the existence of 'potential energy.'
One should argue in a similar manner for the independent existence of ALL
mathematical 'objects.'

My little thought for the day.

-----Original Message-----


In a recent newsletter, I learned something interesting.

"That under orthodox Jewish law, the word "God" cannot be destroyed.
You can't, for example, throw away a piece of paper with the word
God on it--instead you have to ritually bury it or arrange for its
storage. The inevitable question arose over what to do when computers
are
involved: can you erase the word from a word processing document or from
some other digital form?

Last week, one of the leading orthodox rabbis, Rabbi Moshe Shaul Klein,
decided that it was OK to erase or delete digital versions of the word
"God," because they did not contain the actual word, but a composition
of 1s and 0s. If everything is binary underneath, the rabbi reasoned,
then even the word "God" is not actually G-o-d but a series of
numbers."--Alice Hill

Okay, so if everything is binary, including fractals, I guess that means
that they don't really exist. Just a bunch of 1's and 0's.  But we all
know that fractals exist, since we spend a lot of time creating them and
coloring them. :)  Now my questions is--when did fractals first exist?
With the invention of the computer, or did they exist but we were unable
to perceive them? Jim Muth asked where do fractals go when the power
fails. Do they continue to exist or is it really our power of perception
that is lost with the loss of electricity? If they exist only while on
the screen, are we guilty of murder every time we change screens?

Sorry about my rambling, but it has been too long since Jim has had a
good philosophical post. To make up for my rambling, here is a PAR.
Instead of seeking infinite detail and a fancy coloring algorithms, this
one is "Simply Elegant."

Subject: (fractint) Can I load my customm color maps (.pal) in real time during color cycling?
Date: 01 Feb 1999 00:09:32 EST

I have been using ver 19.6 to color cycle color compositions. I edit the
palates to achieve a smooth or musical effect.  Some work better than others
of course. And then after composing various 256 color subroutines I want to
splice them together or learn how to load them so that they "play" without the
delay that occurs when I pause to load the new palate.  I have tried to edit a
custom text file, adding the text information from multiple subroutines, and
loading it, but only the first 256 colors load.  Any ideas on how to do this
in Fractint?

I also want to know if I can respecify key loaded color maps other than
"default" = Dkey.  IE: the number keys (1-9), the alt & shift + number keys.
I use the preprogrammed colors for studies, but my own palate tastes are
different.

I also want to know what "routine" or filename controls the randomization
colors from the enter key...Is this something that I could use to load a group
of my precreated files from memory so they would load instantly.

I have not been programming any source tools but I have a good eye toward
color
editing, and have been rewarded with the power of fractint for the past 3
years.

I would appreciate if if someone had suggestions or could point me toward some
tools that might help me to sequence my color compositions.

Thanks.
