All is quiet on Christmas eve. So quiet that even the monsters
are not speaking. Just sitting back to back sulking.

This is a test to see if the list is alive.

Hi fractint artists,

This happened to me last night.  The list returned 3
of my posts.  So now tonight I get through.  While I
can, I will forward any on topic posts.  If someone
else like Janet will help, we may be able to continue
through the holiday.  For some of us this is a time
we can get to our art,

Subject: (fractint) Joy to the Chef
Date: 25 Dec 1997 10:12:49 -0800

A friend sent me these delightful stories of cooking disasters.....I hope
you and yours are having a lovely....and disaster free day

 THEY GOT MASHED, ALL RIGHT
   Pat Livingston of Dallas was married to "a big, physical fellow," she says.
   One day he volunteered to mash some potatoes that she had cooked in a
   pressure cooker. You know where this is going.

   "I overheard him in the kitchen grunting and shouting, 'I can't get this
lid
   off, uggghhhh, uggghhhh,' " she says. "I heard a huge bang that sounded
like
   the day the universe was born. I rushed to the kitchen, and there the
big guy
   stood with the pressure cooker in one hand, the lid in the other, and
   steaming potatoes exploded onto more than half of the kitchen. We're
talking
   the ceiling, walls, cupboards, stove, everywhere. I never knew potatoes
could
   explode like that."

   ONE OVEN DESIGN THAT'S ABSOLUTELY DYNAMITE
   After watching Julia Child, Janice Kelly of Grand Praire was inspired to
make
   an "authentic curry." Ms. Child recommended heating the coconut to
facilitate
   removing the meat from the husk.

   "One rather vital bit of instruction I missed was to drain the milk from
the
   coconut before heating," she says. "I put the coconut in the oven, set the
   timer and went off to a meeting. When that steam-powered bomb exploded, it
   blew the oven door off and spewed coconut milk about 10 feet in all
   directions! I returned to find the oven door dangling from one hinge. I
   cooked on that GE wall oven for another 20-plus years - all with a
   coconut-sized divot in the door."

   YEAH, WELL, AT LEAST THE ALMOND SLICES ARE GONE
   When Donna Graebner of Dallas was young, she and her sister watched their
   mother ice an angel food cake and sprinkle it with almond slices. Some fell
   into the hole in the cake's center.

   "Mom didn't want to cut into the cake in front of the guests only to find a
   mess of almond slices stacked up in the hole. So she got the hose to our
   vacuum cleaner and stuck it down the hole. As soon as we turned it on,
almost
   all of the cake was sucked up into the vacuum cleaner. What a disaster.
   She had to pull the remains of the cake out . . . and wash out the hose. I
   don't remember what she ended up serving."

   AFTER THREE ROUNDS, BIRD CONCEDES DEFEAT
   Carrollton resident Estela DeLa Fuente had never cooked a turkey this
big: 22
   pounds. She rose at 5:30 a.m. to wash and stuff it, place it in a
cooking bag
   and pop it in the oven. She was headed back to bed when she noted a "glow":
   The bag had ignited. She removed the turkey, pitched the bag, basted the
bird
   and put it back in the oven. Only now its string cradle was dangling
over the
   pan.

   "I peered into the oven to see a small flame eating its way up the string,
   much like you see a fuse burning toward a stick of dynamite in the movies!"
   she says. Out came the bird. Off came the string. An hour later, the smoke
   detector went off, waking everyone in the house. One of the wings had
dripped
   fat, which caught on fire.

   "After the third fire, I wasn't sure whether I'd ever get the turkey to the
   table," she says. "But he did manage to get cooked and eaten, with a lot of
   good-natured teasing from everyone."

   AND FOR HER NEXT TRICK, SHE WILL LICK DRY ICE
   Dallas native Lynda Doty was making caramelized sugar for her family.

   "In an unthinking moment, I lifted the wooden spoon to take a quick
taste of
   my delicious-smelling concoction (don't all good cooks taste as they
   create?)," she says. "The caramelized sugar adhered the wooden spoon to my
   tongue! There I stood, alone in my kitchen with a large wooden spoon
dangling
   from my tongue, not knowing what step to take next, and all the while
   realizing that whatever I did, it would be wrong!" She finally loosened the
   spoon with ice water and butter.

   "The holiday went on as planned, although I did lose a few taste buds that
   day!" she says.

   "INSTANT" RECIPE FOR GUARANTEEING YOU NEVER EAT A POTATO AGAIN
   After moving here from Korea, Sue Chase decided that if others could cook,
   she could, too. She began with instant potatoes - "thinking that if
   they were instant, it would be easy to make," she says.

   The potatoes looked too moist, though, so she added another package of
   potatoes - which made the mixture too dry.

   "To make a long story short, after going to the store and purchasing two
more
   boxes of instant potatoes, I had a pan of potatoes for an army mess tent.
   Since there were only four in our family, we ended up eating a variety of
   mashed potatoes (pancakes, croquettes, etc.) for the next seven days."

   NEXT TIME, WE RECOMMEND A HEARTFELT POEM
   Allen resident Angie Houghtlin's younger sister decided to bake her way
to a
   young man's heart. The tool: chocolate cake.

   "My sister, who, to this day has absolutely no interest in cooking, and who
   still eats cereal for almost every meal, really outdid herself," she says.
   "When my brother and his friends sat down to cut the cake, therein lay a
   surprise. Not one of the eggs had been mixed into the batter. There they
lay,
   in all their hard-cooked glory: whole and with yolks intact. She has never
   lived this down."

   IT'S FUDGE, I SWEAR IT IS
   Eager to impress her new husband, Michelle Padgett Perkus of Richardson
   decided to make her mother's fudge. She cooked the mixture until it was hot
   and bubbly but could not get it to the "soft ball" stage. Convinced the
batch
   was bad and lacking a garbage disposal, Ms. Perkus did what many a young
   bride might do.

   "I dumped the hot fudge failure into the commode," she says. "The whole 4
   cups of hot fudge splattered to the bottom of the commode, where it quickly
   formed a soft ball. When I tried to flush it, the brown gooey glob of fudge
   firmly attached itself to the bottom of the commode and refused to flush."

   Her husband came home. He laughed, she cried.

   "The worst part was having to spend many hours digging that fudge out of
our
   commode with a spoon!" she says.

   THIS DIVINITY SURE DOES TASTE MIGHTY ... REGULAR
   It was back in the late 1930s that Thelma Hopkins' sister made one very
   unusual batch of divinity.

   "I can remember it and smell it like it was yesterday," Ms. Hopkins
says. "We
   started to eat it and realized she had used Fletcher's Castoria (a strong
   Laxative) instead of vanilla. There were six of us kids so you know we
didn't
   throw it away. We ate it. We passed each other on the way to the bathrrom,
   but we survived and laugh at it every so often."

   JACK FROST, GET OUT OF THE COUNTRY. ASAP.
   Dallas resident Jeannine Verinder has always liked the part of that song
that
   goes, "chestnuts roasting on an open fire."

   "Several days before Christmas one year, I happened to notice chestnuts for
   sale in the produce section, so I bought some," she says. "My husband
   and I didn't have an 'open fire,' so I decided to roast them on an open
   cookie sheet in the oven. Was I ever surprised when the chestnuts started
   exploding. We spent hours cleaning those fibers off the inside of our
oven."

   DRIVEWAY STILL SOLID AS A ROCK
   As a young bride, Jan Wallace of Mesquite didn't want guests to see her
   relying on a cookbook.

   When they arrived, "I hurriedly put away my cookbook," she says. "I
   remembered that the recipe for gravy called for one 'something' of flour
and
   unfortunately I chose the word 'cup' to replace 'something' and added a cup
   of flour to the grease. I added and added and added milk and it was so
thick
   we could have used it to pave the driveway."

   At her guests' suggestion, they skipped gravy altogether.

   MM-HMM, RIGHT. MEANWHILE, CHECK ON THE KID'S LIFE INSURANCE POLICY
   Virginia Davis of Dallas insists she is not stupid. No, she was simply
young
   and inexperienced in the ways of canned ham.

   She stuck the can in the oven for just a "few minutes" to melt the gelatin
   around the edges. Then she forgot about it. Company arrived.

   "Just as our nephew passed the oven, it happened - the oven door flew open
   and the exploded ham flew out of the oven, missing the child's head by
   inches," she says. "As it hit the wall, the shredded ham was flung
across the
   kitchen and was literally hanging from the ceiling. I remain extremely
   thankful that I did not kill my nephew with an exploding ham."

   THAT'S NO HAM, THAT'S MY ...
   John Lowrey was working days, his wife Mary nights. He came home one night
   and noticed an unfamiliar smell. He went into the kitchen and saw
"something
   round" on the floor.

   "At first I thought that an intruder came into the apartment and killed my
   wife and cut her head off," he says.

   He turned on the kitchen light.

   "I saw 'stuff' hanging from the ceiling, curtains, walls and floor!" he
   recalls. "The oven door was open and there was a twisted thing on the
floor.
   After calming down, I looked closer. The twisted thing was a ham can. The
   ball on the floor was an exploded ham and the 'stuff' all over was more
   ham."

   The instructions never said to remove the ham from the can, said the
Mrs.; it
   just said "cook at 325 degrees."

   "You know, she was right," he says.

   THAT BARB ALWAYS WAS A LATE RISER
   Lynn Dickson's mother-in-law brought over her bread machine so that Ms.
   Dickson and her husband could try it out. She also brought a plastic bag of
   powdered milk, which she said would improve the flavor of the bread.

   Her husband tried it and made what seemed to be a perfect loaf. But he
threw
   it away; he didn't like the crunchy texture.

   That evening, Ms. Dickson noticed that a small plastic bag containing the
   cremated ashes of her deceased sister, Barb, was missing from a table in
the
   bedroom.

   "I had recently flown back from out of state following her funeral with her
   ashes in the bag until I could locate a suitable permanent container for
   them," she says. "When I questioned my husband as to where 'Barb' was, his
   eyes widened and with a grief-stricken look on his face, he exclaimed, 'You
   are not going to believe what I did! I put her in the bread!!' In a
state of
   shock, I asked, 'All of her?' 'No,' he cried, 'Just two tablespoons!' "

   Unsure whether to laugh or cry, they finally began to laugh, knowing that
   Barb would enjoy the humor of this incredible story.

   "We thought of many humorous sayings at that point, such as 'Well, Barb
   always wanted to be rolling in the dough!' or 'Barb was so well-bred!' or
   'Barb has truly risen!' "

Have you looked at the GNU gmp library? It's free with source and
documentation and includes at least simple transcendental functions (I
think). It is written in C and includes assembler code for many
processors. There's also a C++ wrapper ("cln") for it that is, of
course, much nicer to use because you have overloaded operators
(really nice to write "z = z * z + c; when z is a 200-digit complex
number :-).

I thought about implementing a deep zoom fractal engine with it
recently, because it includes algorithms for multiplication that are
better than O(n^2) like fractint (O(n log n) and O(n) even, I think).
Probably that would be useful only with *really* deep zooms, though...

Dear List Readers-

This is my first post to the list.  I'm a relative fractalint newbie.

Can someone please enlighten me on the following:

Our local PBS station out of LA (KCET) recently aired
 a program on Fractals, hosted by Arthur C. Clark.
I believe some of you saw it, as it was mentioned some posts past.

In it, the developer/owner of Iterated Systems was interviewed.  During his
interview there was a demonstration of a software filter which was
used on a severely data reduced (pixelated) image of a part of a
parrots eye.

By passing the data set through the filter one obtained a substantially
enhanced image at seemingly higher resolution than the original low resolution
image.

Could some of you out there in the "know" on these sorts or subjects
please comment on this.

Historically, we have never been able to obtain high rez output from
low rez input, regardless of the processing applied.  You can't create
"information" out of nowhere.

But I suspect, due to the observed self-similarity exhibited in fractal images,
using a "reverse fractal filter" (for lack of a better name), based on
fractal mathematics, would result in output which probably resembles the original,

rather than an exact recreation of it.

Does anyone know if these processing techniques have ever been applied to
astronomical observations, say image data from the Hubble Space Telescope?

If one can recreate the parrots eye from a hand full of pixels, wouldn't it be
possible to fractal process an image taken at the limits of an instruments
capabilities and effectively multiply the power of that instrument
10's or 100's of times maybe 1000's of times?

I apologize if I've posted this to the wrong newsgroup, but it seemed
like a good first approximation.  Please advise me of an alternate if one
is aware that such exists.


Dying to know (the ramifications are astounding)
Richard

Well, that too (these days I only bother jumping on Make Money Fast!
scams); but I was thinking more of such wanton running of software of such
dubious pedigree....




I dunno, Tim turns his back for five minutes and look what happens...

Michael Barnsely (the developer/owner) has written a book called "Fractals
Everywhere" that covers the ground you're interested in. Iterated Systems
has since bought algorithms for other extremely high data compression
methods (weighted finite automata, etc.).

Certainly, if you over-enlarge a portion of someone's skin in a portrait,
you just see more skin - you do not start seeing skin cells!

No doubt someone has applied them for their own use, but the data itself is
stored in a lossless (noncompressed) FITS format. Even JPEG and GIF
compression (one lossless, the other with a restricted palette) are too
damaging to the data to be used for recording purposes. In fact, FITS files
are not limited to two-dimensional images (one- and three-dimensional
images are also common), and its headers can contain massive amounts of
data - not just a description of how many images there are in the file, and
the number of dimensions and bits per pixel each image has, but notes on
what telescope took the photo, what instruments were attached, what
wavelengths were gathered, what part of the sky is in view, catalogue
numbers of any objects in the view, UTC timestamp...

One reason for the aversion to compression in FITS images is the age of the
format (it was designed to be conveniently stored on punched cards). FITS
files are no doubt tarred and gzipped for archival purposes (perhaps with a
summary of the header stored separately for indexing), but that is not
strictly an image-compression issue.

The other reason is that in astronomical photographs _every_ bit is
considered significant data - considering the amount of effort that has
gone into obtaining it, this is not surprising!

The extra "information" would still be fake. The results might look good,
but they would be useless for research purposes.

Hi,
Three pars generated from two of Paul Derbyshire's Quartz formulas. For some
really good ones download the par file on his web page. If you hate these,
please tell me--I don't know what I'm doing and appreciate tips. Peter

OK gurus,

See if you can explain this.  Here is another case where just changing
the  magnification a little changes the image a lot.  The first one is in the
transition  between the next two.  Use 800x600x256 setting since it image is
sensitive to scale.

Subject: (fractint) some more variations
Date: 26 Dec 1997 22:49:08 -0800

I've been playing around with palettes and have gotten
some interesting effects when color cycling on the very
nice Christmas ornament from Wizzle and Jill Lawson.
(It's not Christmas anymore!)  The main effect of this is
in the cycling and something disturbing is happening at the
edges.  I think some of the house guests watching this
were on the verge of a seizure like those children  in
Japan watching animations.
   I also took the lovely elegant variation of Jacco's contest
entry by Wizzle and turned it into sort of an art deco neon
sign.  This also needs to be cycled.  (Now I  will try to stop

(Now I  will try to stop

I loved all your color variations and spend a lot of time playing with
color myself.  When I'm looking at fractals on the web, I so often wish the
artists had taken a little more time experimenting with the "perfect" color
map.

The precise control Fractint provides over color mapping is one of its most
wonderful features.  I hope.....if we go to true color....there is some way
to produce something like a palette....or turn certain areas of the fractal
black like we can do in Fractint.

Compare the two versions of Paul Carlson's contest entry.....one with a two
color map I made after seeing how wonderfully bold that makes certain
fractals....and one with my taupes3.map which uses the more conventional
gradiated bands of color.

2colors            { ; Paul Carlson's contest entry

  params=0/0 float=y maxiter=256 inside=0 outside=atan
  invert=0.01/-1.6/0 decomp=256 biomorph=0 colors=@2tealvio.map
  }

taupes3             { ; Paul Carlson's contest entry

  params=0/0 float=y maxiter=256 inside=0 outside=atan
  invert=0.01/-1.6/0 decomp=256 biomorph=0 colors=@taupes3.map
  }

I just counted .....I produced 8 variations of Paul's 2-color map!!!! all
in the pastels I like so much. Thanks so much Paul...I've learned oodles
from seeing your images and maps.

I didn't realize colors weren't always saved......<<sigh>> so much to
learn!!! Here are the two takes on Paul Carlson's contest entry (both are
my color maps) which I think really demonstrate dramatically just how
important a color map can be.  I think the first image is great (my map was
a variation on the one Paul used in the contest).  The second image is
definetly so so.........sooooooooooooooooooooooooooooooooo

BTW....I have a friend doing fractals now.....and she makes great web

She just sent me an email saying she is going back to Fractint because the

I was looking at Paul Carlson's homepage and got to wondering if we had the
formula he used......

Clifford Pickover's quartic variation of Ushikis's "Phoenix" Julia set
equations: Z = Z*Z - .5Z + C, X = Z*Z - .5Y + C, Y = Z, Z = X

I haven't learned how to write formulas myself yet (may be beyond me entirely).

Howdy all, hope your holidays were as bloody as mine!  (I
got Quake II... ;)

    I've been attending the list sporadically lately, but
am now set up at home and will be getting more involved in
the fractal fracas, I promise!

    News:  I've managed to produce some C++ code (a.k.a the
DEEPER prototype) which compiles under GNU's g++ compiler
(with a couple of warnings) that can be used to zoom
randomly into the M-set, and probably other escape-time
fractals.  And unlike my previous attempt, this one doesn't
seem to fragment the hard disk.  Anyway, I'm at the stage
now where I'm trying to decide whether to try to add my
algorithms into Fractint, or instead set it up as an
add-on, similar to the way the FILMER program functions...
if that's possible - I'd need to read up on the abilities
of a DOS batch file... right now, I've got a DOS batch file
running the DEEPER proto and FRACTINT in an infinite loop.
I should have this prototype and information on how to try
to use it set up on my web page before the evening is out.
Comments, suggestions oh so welcome!

Happy New Year, and remember, Think and Thrive, Don't Drink

Hiya Jason.....

Congrats on getting set up....were you the one crashing the net yesterday
with your new Christmas toy?? (you and 18zillion others)????

I don't want anything that fragments my hard disk.....it's in two pieces
(partitions) and I would prefer that it stay that way.

My holidays were fine...I downloaded Iterations, Flarium24 and TieraZon from

http://home1.gte.net/itriazon/

The programs make nice fractals but I find the color control baffling.  Can
anyone help me?

I use MS Internet Explorer 3 and its Internet Mail.  Anyone on this list use
these products and know how to set the <reply to> field?  BTW, I found
a parameter setting for the number of characters to allow before line wrap.
I set that to 80.

Try Trumand (the Windows 3.1 version). It uses Fractint color maps and has
several options for generating truecolor fractals, including animations as AVI

I'd like to try TruMand (assuming it is politically correct....and doesn't
make any sexist fractals)....does it run under win95??

P.S.  I've been pondering all day....just what IS a sexist fractal??

Richard,

    Welcome to the list!  Glad to hear that you caught that
PBS special... I missed it myself.  I think your question
is a fine one for this list... and here's my unprofessional
opinion, especially since I haven't seen the film.  You are
on the right track when you say:

> But I suspect, due to the observed self-similarity
exhibited in fractal images,
> using a "reverse fractal filter" (for lack of a better
name), based on

probably resembles the original,
> rather than an exact recreation of it.

    The parrot's eye produced by the fractal algorithm will
be similar to, but not identical to, the actual parrot's
eye photographed.  The same 'restoration' technique can be
used to recreate any self-similar object when a bare
minimum of information is available; easy examples are
pictures of clouds, wood and stone surfaces - add a little
randomness and your computer can produce pictures which
look like the real thing.

    Unfortunately, these approximations cease to match the
real world if we magnify or change the scale very much.
The approximations tend to look exactly the same no matter
how much you magnify, whereas things in the real world
reveal new features (cells, organelles, molecules, atoms,
etc.) as you magnify... this is linked to the fact that
different forces in our universe act over different
distance scales.  So we couldn't use a fractal algorithm to
improve our data; we could only make our data simulate a
standard, but any new, 'true' information would appear
strictly by chance.

    Ok, that's my brain.  Two more things: 1) The
Mandelbrot set is a fractal that exhibits the phenomenon of
novel geometry at all scales (well/poorly phrased?), and
thus is fun to explore, and 2) keep asking questions, even
this one again, if I butchered my explanation and no-one
else responds.  Others here can provide a much more
technical answer than I can.  Again, welcome, and Happy New
Year!        Jason

From the menu MAIL | OPTIONS , go to the SERVER tab and make sure the
"Email Address" field has your full address:  [e-mail]

Then hit the "Advanced Settings..." button from that same tab, where you

Well, sexism may be defined as an attitude or behavior based on
traditional stereotypes of sexual roles. When you consider the
essential zooming nature of fractal explorations a little thought
must lead to the conclusion that all fractals are derived from
essentially masculine behaviour.
After all... we do it deeper.

Running, ducking and swerving...

Subject: (fractint) DEEPER Program update
Date: 28 Dec 1997 11:17:12 -0500

All,
    Ok, I've got a zipfile on my web page - the link from
my main page is a little obscure, on purpose... it's below
where I mention that I've moved to Vermont.  Anyone who
wants to download the stuff and mess with it is welcome to,
at their own risk, but the disclaimers make that point
clear (prob'ly scare folks off, actually... hmmm).
    I've got a little more updating to do to the readme.1st
file this morning to describe what the code does...
basically the program chooses a pixel at random, but the
liklihood that a pixel will be chosen depends on its
'color' (iteration value) so that 'deeper' pixels have a
higher chance of being chosen.  The winning pixel 's (x,y)
location is used to center a zoom box on...  but this'll be
in the readme.1st file if you want the whole story.
Basically, the zoom algortihm is random.  I'm working on a
smarter algorithm...
    I've also decided to develop this as a standalone
add-on (like the Filmer program is) because I think I know
how to proceed with that.  Ideas and suggestions still
welcome!
HNY, Jason

Hi Paul,

Thank you Paul and Lee!



                  Care and Feeding of 3D_Balls_Mset

You're going to need those parameters and colors to make your own 3D Ball
images, boys
and girls. So if you try to bake these at home, you may want to load
3dballs.par after you
have located an interesting MSet region using standard formula.  The initial
un-zoomed
MSet shows up mostly black without detail using Paul's formula.  So locate a
midget or
Misiurwicz point, and note the coordinates and magnification. Then load
3dballs, enter your
coordinates and you are set.

3dballs  { ; Copyright (c) Paul W. Carlson, 1997
  type=formula formulafile=3dballs.frm
  formulaname=3D_Balls_Mset passes=t
  params=0.0065/150/8/30
  float=y maxiter=3000 inside=253 outside=summ
  colors=000c40<28>zW0aG0<28>zz00C4<28>0zR0CC<28>0zz00O<27>FFxGGzI0K<28>fO\
  zO08<28>z0fO00<28>z88000<13>000
  }

Now there must be a better way. The above method should be easier: Find region
using
standard formula, load Paul's formula and colors without loosing the
coordinates. How do
we do that?


Here is one I made. It has some very overlapped balls.

Jack was so kind as to answer my question about sexist fractals with

((P.S.  I've been pondering all day....just what IS a sexist fractal??
>(pondering brought on by Beth's earlier comment)

Well, sexism may be defined as an attitude or behavior based on
traditional stereotypes of sexual roles. When you consider the
essential zooming nature of fractal explorations a little thought
must lead to the conclusion that all fractals are derived from
essentially masculine behaviour.
After all... we do it deeper.

Regards - Jack

and when I visit Jason's page I see he does "unmanned
deepzooming"........can that be quadratic equations as 4 play?? (nice
background Jason....but I can't find the exploding hams except here.)

Date: 28 Dec 1997 11:22:05 -0800

Thanks for the encouragement, Wizzle.
     When you are using Flarium, under "view" there
is a choice "color parameters" that gives you a screen
"Flarium 24 color controls"  You can specify a number
for R G B that will change the palette.  There is also a
choice for color cycling under view and also in the color
controls.  I don't think you can change the colors by
choosing or importing a palette like you can in Fractint.
    I have been spending endless hours on the "Inkblot-
Kaos" program from Iterations et Flarium.  It is simpler
than Flarium.  It makes incredibly nice images-some of
the Julia sets are luminescent and mandala-like and most
people who don't know about fractals are very impressed.
Quite a few could be book covers.  You don't have the
sense that you are making an image "from scratch" or
using math like you do in Fractint but it's fun and easy.
      I think these programs are from Stephen C. Ferguson
and you are imposing the "stalks" and "bubbles" which
are Paul Carlson's method (tell me if I have this wrong!)
I think it is great that people have made these as freeware,
(like fracint itself and truemand etc.), not that I would mind
paying money for them but it makes me feel like someone
has done something creative that they care about.

Hi Jason,

Not happy with DEEPZOOM I wrote several years ago?
So you wrote DEEPER?  :-)   Well fine!


In your documentation you ask if there is a good way to
control your batch file. Here is a batch file which exits
when you press 'A' for abort.  Copy the following into
NONSTOP.BAT.  Replace 'dir' with whatever programs
you wish to run.

ECHO OFF
:TOP
ECHO Press the 'A' key to stop
dir
TEST4A
IF NOT ERRORLEVEL 255 GOTO TOP

To create TEST4A.COM (from PC Magazine about 10 years
ago) copy the following debug script into the clipboard.

Then Open a DOS Window window (a DOS window
with the tool bar showing). Click the past button and the
text will be blasted into debug and create the COM file.

debug
E 100 B8 00 06 B2 FF CD 21 74 0C 0C 20 3C
E 10C 61 75 06 B0 FF B4 4C CD 21 C3
RCX
16
N TEST4A.COM
W
Q


Now type NONSTOP and the 'dir' command will run repeatedly
until you press A or a.

Jay

Date: 28 Dec 1997 13:31:36 -0800

Here are a couple of new pars I came up with....they took a rather long
time to generate with my 100mhz pent...but may be useful for the color maps
which I think are particularly elegant (if you can't wait for the images).

      |z| <= 100
}

I've included the formulas for those that don't have them. Also....I think
elegance2 is a good example of the stripe-y-ness of gifs-sans-anti-aliasing
adding to the quality of the image.....I think this one has a very deco,
painterly quality.  Without the stripes in the background I believe this
would be a rather flat looking composition.  Sooooooooooo....once
again.....a plea to leave us with "the color palette" if Fractint moves on
to true color.

Jay....

I had a really hard time deciding exactly where to stop rotating the
colors. ...and I agree...that is a wonderful image as well.  I usually end
up with at least 4 color variations that I save when I find a good
image.....had to buy a zip drive to keep all the fractals from overloading
my itty bitty 2.6 gig hard drive. <<sigh>> I remember when 800 megs seemed
like more space than I could ever possibly use.  I just finished loading up
the third (!!!!!) 100 meg zip disk with fractals. My next puter is gonna
have an internal zip drive...I just love it. At $129 it was a great
buy........highly recommended....mine just plugs into the parallel port but
has a nifty interface so I can still print thru that port as well.

Handy, indeed, if we only could...............please read.  :-)

Hello Fractintiers and DeepZoomers,

For your enjoyment and WARNING - a little history.........

DEEPZOOM(tm) was introduced to the world back in '93.  It has since
been stored in a vault at Spanky, but now that it has been rendered
harmless, it is lately available at my page (you will understand):
http://www.geocities.com/CapeCanaveral/Lab/3825/Software.htm

Someone in Alaska had bragged of zooming to 44 digits using BASIC.
Another complained of a deep zooming program that set you back
$90 (a lot in those days).  $90, and 44 digits!  I could not stand it, so
that very evening I wrote DEEPZOOM. The next day I released it upon
the world.  Oh, if only I had known....

Arthur Clarke had warned us.

A lively discussion followed as 13 versions were announced.  I
quote here a few postings from that time in the distant past which
included repeated warnings and even an example 70 digit zoom. In
those days of 486/66 machines, there was little hope for any who
caught Zoom Fever.  Machines and eyes were locked up for days
as the little white dot slowly crossed the screen.

The fever was speading.  Those who could not get it, wanted it.  I tried
to control the technology, only releasing executables and hints of how
it was coded.  But it was unstoppable!  It was only a matter of time...

Finally, extended math was added to Fractint, dooming my DeepZoom
and all (about 270) who had a copy of DeepZoom. DeepZoom's grasp was
replaced by an even tighter grip, Fractint's, which even the fastest Pentiums
have not broken.   And now, with Deeper.exe, our fate is sealed.  We
are caught in the trap where not even a twitch of the finger is required
as the lock is now automatically maintained through ever deeper zooms.
It only takes the pressing of a single key to release us, but not one of us
can make the slightest move.  The body becomes totally frozen as
the eyes search the depths for the tinniest midget....

Oh, if only I had known....

OK, listen up all you lerkers and quiet observers of the chaos and orbiting
articles on sci.fractals.  Are we just going to sit and complain about not
enough bits?  --  No!  You want more bits - for free?  YES!  Just send me
email and I'll send you version 0.01 MSDOS executable of a 70 digit zoomer
I wrote last night.  It comes with only one guarantee: it will take up even
more of you 486/66 CPU time than ever before ;-)   It runs at about 300
iterations of z := z^2 + c per second, requires SVGA and patience.  Send
me email and I'll hit you with 2 uuencoded files of total 79K.  It is a
zip file (pkzip1.1).  You get to choose the picture size from 1x1   :-)
up to 1024x768.  I adjust SVGA mode, jumping from 320x200 to 320x400 to
460x480 to 800x600 to 1024x768 as needed.

Now remember, it is one day old and free, so be kind.

       A warning to DEEPZOOM users.

Few can forecast the effects of technology on our futures as well
as Arthur C. Clarke.  Since he has written of at least one who
zoomed too deep once too often, we might want to be careful.  In
his 1990 novel _The Ghost from the Grand Banks_, he describes one
Edith Craig at the Torrington Clinic for psychological disorders,
who is mentally locked in a 40 digit deep zoom into the Mandelbrot
Set.

Hmmmm.  There are now about 70 who have gotten my DEEPZOOM program.
In the novel Clarke notes that "there are no less than sixty-three
examples of Mandelmania now in the data banks."

Warmly,
Jay "Not tonight honey, just another factor of ten, just..." Hill

In an email I was asked:
> A naive question at a late date: what's Mandelmania?

In the novel, MSet pictures were everywhere by the turn of the
century.  Some people just couldn't handle the infinite detail
and beauty.  They had to see it all, experience it all.  Some
let it get to the point of an incurable Mandelmania.  No cure.
Well, about 80% make an 'adjustment' back to normality by use
of medications and for some, as Clarke indicated, implants - duuh.


The real line portion of the Mandelbrot Set provides an exhibit
of several types of iteration behavior.  Outside of the interval
(-2..0.25) iteration diverges.  An example of a Misiurewicz point
is -2.  Then inside the buds and cardioids the iterations become
periodic.  On the edge of a bud or cardioid iteration convergence
is very slow since the Lyapunov exponent is 0.  Other points are
chaotic with Lyapunov exponents greater than 0.  But the Lyapunov
exponent is defined in the limit of infinitely many iterations.
Without carrying the calculation to infinity, can we determine if
an arbitrary point is chaotic?  I doubt it.  Aha!  An excuse to ZOOM!

The Lyapunov exponent for c=-1.8 is approximately 0.4046 which
certainly looks chaotic.  I wondered what the MSet looks like if I
repeatedly zoom in on such a chaotic point.  So I used DEEPZOOM to
do just that.  With -1.8 in the center, each increase in magnification
shows the point -1.8 missing midgets repeatedly, with small ones
near -1.8 always moving just out of reach.  Finally, at 10^68
magnification I moved the focus over a pixel or so to a midget
right next to -1.8.  The final view at 10^70 magnification is shown
in 18000000.gif which I just posted to alt.binaries.pictures.fractals.
The gif took more than two days to compute on my 486/33.  The deepzoom
parameters were

maxiter = 3200076
x =
-1.79999999999999999999999999999999999999999999999999999999999999999941756
y  =  962e-72
dx = 1280e-72
dy =  960e-72

My warning post (see above) got a few interesting replies.  Alas, it
looks like it's too late.  One reply was, in part, "...seeing as how my
brain is already warped and locked into a permanent ZOOM state...".

And this. "You can add me to the 'mentally locked up Mandelbrot Zoomers
Set'.  I have recently downloaded DEEPZOOM, and have started playing
with it.  It's great.  This program is just another great reason to
leave my computer on all night."

The current version, 0.10, has an improved color scheme using 108
rainbow colors before repeating.  Also, I have added a sleep mode
which aids TSR screen grabbers.  In four days, DEEPZOOM will be two
months old and is still FREE.  ;-)  Maybe by then (Real Soon Now) I
will add gif-ability.  Then automatic generation of a gif sequence
which can be used for an mpeg ought to really jam my machine.  If we
magnify by a factor of two, there are obvious reuse of calculations
from the last view.  There should be information reuse even if the
magnification jump is 15%.  Any ideas?

Warmly,

That equation is not part of Fractint, but I just translated it into

If anyone wants to set up a fractal homepage.....I highly recommend

www.simplenet.com

For a piddly $10 per month you get unlimited...that's right...space for a
homepage.  With fractal gifs taking up the space they do.... one can use
all the space available.

I have two other providers who dole out 5 and 2 megs.....<<<hurmpf>>> for
homepages.

The $10 is just for homepage space...no email or connect time.  But if you
already have a competitive way to connect.... this can be a bargain. I
think I have about 30 megs of junk at simplenet and they haven't made any
waves.  Note that the files there must be connected to the web...they can't
just be for storage. And for the most part the server is fast and stable.

Subject: (fractint) Fractal encryption
Date: 28 Dec 1997 19:54:49 PST

Greetings fellow fractal addicts...

I don't know if this topic has been discussed on this list before, but
here is my question.

Could it be possible to use fractals as a way to encrypt information?
How strong the encryption would be?

I have thought of very simple method. For simplicity's sake lets use the
regular mandelbrot formula. The password (or the passphrase) would be
the initial parameters for an iteration.
Then take the first part of plain text, make first iteration of the
formula, run the result through some convenient hash algorithm and xor
the result with the plain text. Repeat the above steps for the rest of
the plaintext.

I don't know if it would work (due to the fact that  the floating point
calculations would have to be converted to integers and this could cause
inaccuracies in results).

I realize that this is not exactly a topic about Fractint itself, but I
think there are many knowledgable people on this list that have
potential to contribute to this discourse.

It has not appeared here, but has been discussed on sci.crypt. Usually
getting a general brush off.

I have thought about this at length. Here are some specific ideas.
You are suggesting a stream cipher using the MSet as a pseudo-random
number generator.  The key you use is, as you say, the coordinates,
c, in the equation z[n+1]=z[n]*z[n]+c, z[0]=0.

> I don't know if it would work (due to the fact that  the floating point

Floating point must be done with plenty of precision, double (64 bit)
is a minimum.

The main weakness is that the values z[n] are not uniformly distributed.
Although this may be offset by a hash function, it can limit the search
space of the attacker.  Even worse, key values not carefully chosen
lead quickly to divergence to infinity or to a periodic attractor. Only
chaotic c are acceptable. While marginally chaotic c are known
on the boundaries of the components, the only really chaotic values
can be found accurately on the real line.  This greatly limits your key
space - to one dimension.

A possibility of a two dimensional key space might be to include the
initial z[0] as part of the key rather than using z[0]=0.  Care must be
taken that c is in fact not in a bud or cardioid (a component).

For every point that is truly chaotic, a periodic point (in a component)
is only an infinitesimal distance away.  If c is in a component, then
the z[n] sequence is doomed to periodicity.

The Lyapunov exponent is a measure the chaos. But it can only be
estimated by following the sequence to great lengths.  The Lyapunov
exponent will indicate chaotic behavior right up to the point where the
first period is reached. It will then drop in one iteration into non-chaos
values - a disaster if it occurs in your message! Since, at that point
your sequence may start repeating.

A large Lyapunov exponent indicates chaos, which is desirable in the
sequence. However, it also indicates divergence when a very small
perturbation (one bit) occurs incorrectly in the arithmetic. Therefore, the
message sender and receiver must use exactly identical arithmetic
processing. This can be a problem across platforms.

Funnily enough I did once come across a fractal using one of my own formuas
that had a certain - shall we say - gynecalogical look to it.
(Un)fortunately, I didn't save the parameters, and you know what THAT means...
I have a few leads on where I might find it, and if I find it I'll post it up.

Wizzle (as far as I recall, you are a wimmin, handle Angela ?)

I subscribed to your list just before Christmas, and have
been inundated with stuff I have no time to read, as well
as rather inappropriate for your focus, exploding ham
(maybe we could apply that to Spam).

Since I have to separate IETF stuff from yours, how do
I go about changing my mailbox for fractint related to
: [e-mail]  (sorting wheat from the chaff ?).

I like your group, from what I've seen, but using raptop
platform, albeit 2GB disks, I don't space for exploding
ham (Spam might be a different proposition) ...


Thanks, regards,

Subject: (fractint) FPGAs
Date: 29 Dec 1997 09:36:34 -0500 (EST)

    Anyone catch the article in January's Computer Shopper (p. 626) about
'field-programmable gate arrays'? Apparently there are chip designs which
include a sort of static RAM controller for each logic block, thus
allowing the actual function of the chip to be altered at any time. What
this means, in effect, is that one could create a fractal hardware engine
that, when you select a formula in fractint (say Mandelbrot) is literally
rewired to compute a pixel of the set in a single operation (possibly
running this op in parallel as well)... and when you switch over to the
contest formula, the thing re-'programs' itself for that...

   Apparently, while FPGAs that rewrite their logic in realtime are still
somewhat in development, there are commercial versions availible. I'm
going to go see if I can come up with prices for a development kit now...

   Altera, for instance, is offering a research version of an FPGA that

proposal... see the URL, http://www.altera.com/html/programs/phd.html

   Anyone interested? I find myself fascinated by this. I lack the
hardcore knowledge of how fractint formula types work to know how to
write an extension that would use an external computing device, however.
If I can come up with some help on that and round up one of my EE
friends, I'm game, though...

Don't do it. The SparQ drive goes for $199 and holds 1 gig, and the new

I'm a hopelessly non-technical person and new to this list myself.  What is
a raptop? I believe Tim is the great list guru and can be contacted via the
Fractint homepage for email questions.

Hopefully we will stop exploding hams after the holiday season is over.
Myself...I'm cooking a turkey today and looking for Fractals with a New

the puter explode. Nice to have you with us Vince...

Re:

That equation is not part of Fractint, but I just translated it into
a Fractint formula, along with a par file to try it out.  Here it is:

3D_Phoenix_Spirals {; Copyright (c) Paul W. Carlson, 1997

<<snip>>
Paul et al....

I tried opening the par...and it woudln't work.  Neither would the
formula.....muttered something about not being defined.  Did I do something
wrong?  I pasted everything from 3D_Phoenix_Spirals .....to } into a file
and named it properly, I believe....since Fractint found the file. Can you
help??? I'm really anxious to try my hand at the spirals.....one of the
best things I did was a phoenix based on the Fractint standard formula and
pars.

Also...I looked at Paul's homepage at
http://fractal.mta.ca/fractals/carlson/ and want to do flexballs and
bubbles!!!! So perfect for New Years.......any chance of that??? <<<on
bended knees>>>

Paul's images are fantastic!!! And it's great to see how endless the
variations with fractals can be.......so inspiring for a newbie like me.
Makes me think I would have paid attention in math class if I'd known about
fractals all those many many many years ago.

The definitive source for all GNU software is
<URL: ftp://prep.ai.mit.edu/pub/gnu>; the MP package is
<URL: ftp://prep.ai.mit.edu/pub/gnu/gmp-2.0.tar.gz>

I can send you the documentation as postscript by email if you like
(not everyone has the texinfo environment needed to build the
postscript from source).  GMP supports: integers (mpz), rationals (mpq)
and floating-point (mpf) formats.  However, there aren't any trig
operations defined on the floating-point format.  The mpf operations
defined by the package are:

    mpf_add
    mpf_sub
    mpf_mul
    mpf_sqrt
    mpf_pow
    mpf_neg
    mpf_abs

So, you could implement Taylor series expansion versions of the trig
functions using this base of functions.

I asked around a little more and looked in my own books regarding the
convergence of Taylor series expansions for transcendental functions.
My "Numerical Recipes in C" book had some stuff on evaluating trig
functions by continued fraction expansions.  There is also something
called an "asymptotic series" expansion that purportedly converges
faster than the Taylor series, but I haven't found a reference for the
details on that yet.  I don't own any Numerical Analysis books, but
all my other books (Calculus, Numerical Recipes, Ordinary Differential
Equations) are pointing in that direction for detail on evaluating
trig functions by series.  The asymptotic series thing bears looking
into.  Digging around on the web for "asymptotic series" turned up:

<URL: http://www.lassp.cornell.edu/sethna/Cracks/Stirling.html>
    Asymptotic expansion for Stirling's formula for N!

<URL: http://www.astro.virginia.edu/~eww6n/TreasureTroves.html>
    "Eric's Treasure Trove of Mathematics" ... I haven't investigated
    this fully, but I'm bookmarking it myself for later.  This appears
    to have lots of stuff about series, trig functions, etc.  The
    references could yield something useful.

I had no problems.  I use screen capture and then some mild editing
(commenting out the explanatory stuff) in Programmer's File Editor (PFE)
an excellent, free and easily findable text editor and save the frm and par
parts separately.  As I have about as primitive a mail utility as I suspect

Iterated Systems was formed by Michael Barnsley to commercialize
"fractal image compression".  However, their approach has been largely
made irrelevant because of the widespread availability of quality source
code implementing JPEG compression.  "Fractal" image compression and
JPEG are both lossy compression algorithms, but ISI's license
requirements are onerous, their file format is proprietary and
unpublished and their developer libraries are not robust and limited
in their platform support, based on my own experience with their code.
Barnsley has obtained one (or more) patents on the basics of "fractal
image compression" and has essentially curtailed all competing efforts
in the field by litigious pressure.

Since JPEG was adopted as an open standard with patent-free algorithms
(as long as you avoid arithmetic encoding on the quantized FFT
coefficients, which is generally the case since noone wants to license
the patent from IBM unless they have to) with high quality freely
available source code, it has pretty much killed any market potential
for ISI's algorithms except for special purpose niche applications.
The only commercial use of ISI's technology to my knowledge is
Microsoft's Encarta CD-ROM.

Contrast the success of JPEG with the market failure of "FIF" (ISI's
name for their file format).  JPEG is an open standard; FIF is a
closed, propietary "standard", subject to change anytime ISI feels like
changing it.  JFIF files and JPEG embedded in TIFF are published file
formats allowing independent developers to write encoders/decoders; FIF
is a proprietary, unpublished file format and the compression and
decompression algorithms are not only unpublished but patented and must
be licensed.  JPEG is supported in every major image manipulation
program on the planet since its availability; FIF is only supported by
proprietary programs from ISI and a few niche applications.  ISI's code
continues to exhibit a lack of robustness in my experience -- a friend
had downloaded the FIF plug-in for netscape which crashed her browser
and her Win95 when she tried to show it to me.

The "parrot" demo is about 5-6 years old now.  Since starting their
venture with much hype, the Encarta CD-ROM "design win" is the only
one of which I'm aware and that was several years ago.  Beyond
"fractal image compression" I don't know what else ISI has to offer.

Its a snake-oil kind of demo, if that's what you were led to believe.
The basis of ISI's technique is to compute a function F such that its
fixed-point is the image you wish to transmit.  So you start with any
image and iterate it through the function... after a few iterations
the start image converges to the fixed-point, the desired output
image.

Actually, it doesn't.  That's another annoying thing about Barnsley.
Several times I myself have seen him croon that he would "tell you how
to do image compression with fractals", but it always falls short.
Fractals Everywhere manages to lead you down every single blind alley
that Barnsley encountered on his way towards the marketed approach
without telling you the marketed approach.

He published two more books after that one, each with "Fractal Image
Compression" in the title, but they weren't any more substantively
closer to the fundamentals of the algorithm than "Fractals Everywhere".
After receiving shipment on the first book, I cancelled my outstanding
order on the second book based on my evaluation of the first.  The
publisher (I had ordered directly from the publisher) confided in me
that I wasn't the first person to cancel my outstanding order for the
2nd book based on my evaluation of the 1st and that others had come to
a similar conclusion regarding their contents.

Consult the online bibliography of fractal image compression at <URL:
http://liinwww.ira.uka.de/bibliography/index.html> for details on the
algorithm.  Consult the paper by Arnaud Jacquin in Proceedings of the
IEEE (I think, this is from memory) for the real details on fractal
image compression.  Ignore pretty much anything with Barnsley's name on
it if you want real, practical information about the technique.

The book on fractal image compression edited by Yuval Fisher is a good
collection of papers on the subject that covers some of the basic
ground.  Despite the patent problems, work in this area has proceeded
at a flood's pace since the paper by Arnaud Jacquin.  The upshot of it
all is that "fractal image compression" (I use "'s because there is
even doubt that the adjective fractal should be used for this
technique.) can achieve compression ratios comparable to vector
quantization methods.

Thanks Rich......

Interesting articles. I've looked at ISI's stuff and they certainly seem to
be heading down the wrong path with respect to licensing.  Somehow the gif
license seems to be about the right  balance between public domain and
copyright.  I do a considerable amount of graphics for the web...and jpg
has its probs.....so I'm glad gif is available.  The fractal compression
from ISI was impressive....especially since it is non destructive...unlike
jpg. What with fiber optics and getting away from modems in the
future...not to mention how cheap storage space is these days....I'm not
sure we really need to be as concerned with bandwidth as formerly. ISI may
be suffering from bad timing along with restrictive licensing.

It can be done.  You face several hurdles.  Essentially you have to
design "ahead" to make it worth your while.  You have to figure in the
advancing pace of generci CPUs (and DSPs) such that by the time you're
done building the hardware it is STILL faster than the currently
available off-the-shel CPUs.  Of course if you build a hardware
pipeline for computing complex arithmetic or even hard-code the z' := z^2
+ c formula directly into the hardware, then you're going to be able
to beat off-the-shelf generic CPUs.  Don't underestimate the
difficulty of building hardware fast enough such that your efforts
aren't outpaced by the several hundred man years that go into each
of the next generation Intel chips, for instance...

Check for this:
   If every equal sign is followed by the characters 3D, do a global
   replace of =3D with =. Then remove every =\n (equal sign followed
   by a new line\carriage return).

These are artifacts of some Mac based mailers. I see them in everything

The obvious replacement for GIF (and even TIFF in my opinion) is PNG.
PNG is lossless and achieves better compression than either GIF or
TIFF for either palette-based or truecolor image files.  PNG does lack
the "animated GIF" feature, but since I pretty much detest that sort
of thing on the web myself I'm not sad to see it unsupported in PNG
:).  However, for those of you who "must have" this "feature", there
is a working group attempting to define a "multi image" equivalent of
PNG.

I don't know where you got this idea.  ISI's techniques are ALL lossy,
i.e. destructive, like JPEG.  (There is also a variant of JPEG called
"lossless JPEG", but it isn't widely supported or implemented; PNG can
probably achieve smaller file sizes than lossless JPEG for most
source matter.)

> ....I'm not
> sure we really need to be as concerned with bandwidth as formerly.

Just as the "death of the net" has been predicted ever since it was
first made available to a wider audience than academia, I think it
will always be the case that more bandwidth will be needed.  As more
bandwidth becomes available to each user, their appetite for bandwidth
is increased, resulting in a feedback that always demands more
bandwidth.  This is why such statements as "I think the total
worldwide market for computers is about 4." (from memory, attributed
to Thomas J. Watson of IBM in the very early days of computers) and
"Noone will need more than 640K of memory" (Bill Gates in the early
days of MS-DOS) seem so utterly ridiculous now.

> ISI may
> be suffering from bad timing along with restrictive licensing.

My personal experience (and this involved talking with them on the
phone, ordering their development environment for the PC and engaging
in discussions about support on other platforms for their algorithms)
is that they are a greedy, arrogant lot.  Talking with others in the
computer graphics field has affirmed my subjective opinion.  Sometimes
people succeed in the marketplace despite their attitude, and
sometimes the marketplace punishes a firm for its attitude.  I can't
say which is the case with ISI, but their way of dealing with business
opportunities definately made a negative impression upon me and
afterwards I found that I wasn't alone in this experience.

FYI, its not just "Mac based mailers"; its any mailer that sends out
messages with the "Content-Transfer-Encoding" of "printed-quotable".
We've gone through this before when discussing the heretical subject
of PAR/FRM/etc. files as "attachments".  While '=3D' => '=' works for
the = sign, there may be other encoded characters in the message.
Printed quotable uses '=' as its quote character.  The ='s at the end
of lines are indicating that the person didn't include a hard line
break in their original message and a soft line break was inserted
with the = inserted at the end to indicate this.  '=3D' is an '='
because the ASCII character code for '=' is 3D in hexadecimal.  If
there are other quoted characters (namely accent characters for
European languages which aren't present in 7-bit ASCII), they will be
present as '=xx', where xx is the hexadecimal code for the character.

   True. Very true. But if you assume that once a technique is found,
upgrading the hardware of an FPGA (perhaps by simply doubling it and
computing in parallel) is relatively simple, then you at least have a
solution that should be, in the prices I've seen quoted, a much cheaper
and more expandable alternative for the poor fractint user who can't always
swap out his P166 motherboard for a PII-300...
   I mean, if I'm understanding the various things I've read aright, I
don't really need to construct hardware; I need to take the programmable
hardware that's mass-produced and plugs into a PCI interface, and write a
fractal-program-to-card interface that tells the thing how to configure
itself. Right?

Its always more complicated than it seems :).

You will unless you buy someone else's box.  If you're interested in
that route, you can look at companies that let you buy "reconfigurable
computing" peripherals that work as you suggest.  They cost about $4K.
At that price, its more cost effective to buy used 486s (or at this
point, even used P90s!) and gang them up in parallel.

There is no "programmable hardware that's mass-produced and plugs into
a PCI interface".  FPGAs are mass-produced, but not the high density
ones with the fancy logic and PCI interfaces that you've been reading
about.  Those parts are the highest end of the FPGA vendor's product
line and aren't produced in volume yet.  So prices are higher.  Also,
don't underestimate the complexity of the simplest things we take for
granted in software.... have you ever looked at how much hardware it
takes to do a single 32-bit multiply?

Oh...no wiggle....squiggle.....to drive me nuts along with music I don't

mush with a new web toy. I was recently at a professionally designed site
where the product was alloted 1/4 of the page..the rest was devoted to
frames....gak....tiff was waaaaaaaaaaaaaaaaay too big. About as bad as bmp.
Fractint's choice of the gif format was excellent given the probs of
compression versus bandwidth.

Hey, now that's a rather odd answer to my question on doing a Marvin
Martian fractal; must be some sort of cultural differences at work here.

Subject: (fractint) Multiple part files
Date: 29 Dec 1997 18:01:46 EST

Hi folks.  I've been trying to create large size, high rez fractals with
fractint using the Makemig and Simplgif utilities.  I know I've read on this
newsletter before about problems with this.  However, on my old 486DX33 it
worked pretty well.  Now on my new Pentium II 266 I have frequent problems.

Things go wrong at the very first step,  when I press B and create the par
file and enter the number of X and Y pieces I want.  I use Shift-2 to invoke
the par and look at each piece separately.  The last column of pieces is where
things go wrong.  The pieces get put out of order and even get rotated 90
degrees sometimes which is really wierd.

Has anyone else noticed this?  Any solutions?

Bill

How hard and how expensive is a matter of debate :), but probably
off-topic for this list.  Email me if you wish to talk more about it.

Silicon vendors always give away what they call "engineering samples".
Using a few engineering samples one could put together a system for a
modest price that would do something interesting.  How interesting and
at what price/performance are questions that are difficult to answer
without a working implementation though.

I don't think fractint can deil with Klein bottles or other
hyperdimensional objects, but I don't claim to be an expert at the
limits of fractint.

You might try the Geometry Center at the University of Minnesota for a
source of software that might help you out in your hyperdimensional
pursuits though.

I've used the 'b' command to render 3x3 tiles of a single image,
render all the tiles, then make a "MIG" and then use simplgif to get
out a single large image.  It all worked OK on my P90.

I have not had the problem your having but I sometimes find that
occasionaly the Simplgif program
fails to work properly.  It fails to compress the file properly.  When I
attempt to open
the image in Paint Shop Pro I get a bad LZW compression message.

Reducing the number of peices seems to help.


      Any solutions?


I have only ever worked with "Square" images eg the same number of X & Y
pieces.

Yep. Good advice for purely personal storage. However, if you have to
move large files between various commercial parties, a zip disk may
as well be considered the standard- everyone has one.

Subject: (fractint) Raytracing Fractals
Date: 27 Dec 1997 22:46:33 -0500

Ok... I downloaded POVRay 3.0 for Windows, just to be able to project my
plasma-landscapes onto globes (Fractint's globally-projecting capability is
severely limited, as you know). Can someone give me some tips on this?

Also, I was looking at some formulae, and was wondering, especially about
Sylvie Gallet's, do you have some higher inspiration into math, or are you
more like those of us [me] who just sit and punch in things like Z =
cos(x)^r + n * z^2?

Subject: (fractint) Phoenix Formula
Date: 29 Dec 1997 20:20:12 -0800

No matter what I do I can't seem to get Paul's phoenix spiral formula to
work.  He sent me another copy via email which I MOST carefully pasted into
notepad. Both version 19.6 and winfract 18.21 insist that there is a
problem.  In fractint I get error (5), undefined function and in winfract I
get error(4)undefined operator and error (5) undefined function. I've
re-done the file several times using (alternately) the information posted
here as well as the information Paul sent me by email.  Screwy.

Could someone who got the formula to work using Notepad please send me the
file as an attachement to an email?  My email is

[e-mail]

Thanks....I've spent hours on this.....<<sigh>>

Angela,

Instead of spending time on Notepad, get yourself a copy of PFE!

It will take less time than futzing about with Notepad.

Date: 30 Dec 1997 02:59:00 -0600

Greetings,

Seeing how this is the last of one year and soon to be a new one, and it
is also the time of a New Moon, I've decided to end my old Fractal
Page.  The new fractal webpages have expanded by a factor of four, and
may be found at the following URL:

   http://home.att.net/~Paul.N.Lee/PNL_Fractals.html

Some of these images have previously been posted to
news:alt.fractals.pictures and/or to news:alt.binaries.pictures.fractals
.

A heed of caution for those viewing:  "It's under construction."  (But
what website is not.)  Also, if you choose to view the larger size
images of the thumbnails, then expect some download time (they are all
1024x768 GIFs).

Comments (negative or positive) and suggestions may be sent via any
means or address applicable.

Thanks and Later,
P.N.L.

Well Angela (and the rest of the gang at "Fractint") try this!!

Actually, the original par is by  Jan Maarten van der Valk who wrote the
Fractext program (used for the formula).
I just added the color map for the New Year fireworks!!

This par will draw an almost blank screen (showdot and the beep should le=
t
you know when it's finished). Then cycle the colours using the minus key
(the direction of rotation is important!)

I've sent the par file as a plain text attachment since Compuserve has
usually scrambled previous pars that I've posted in messages.

cheers, Les

Oh, dear, here goes a rank amateur trying to give advice. And my images
really aren't very good, trust me. But I think your problem might be that
you haven't added the formulas. The Quartz formulas don't come with
Fractint. They're Paul Derbyshire's. To see my pars, you have to also copy
the formulas into Fractint, as I have them named in my pars. For example in
one par it reads, formulafile=quartz.frm formulaname=QuartzM1A. That means
you have to save the formula QuartzM1A in Fracatint into a file named
quartz.frm. When you run the par, it looks for the formula; if it doesn't
find it, you get an error message. I included the necessary formulas with
the par files I sent in, but, really, the best thing to do is to to go to
Paul's gallery (http://www3.sympatico.ca/bob.beland/fractgal.html). There,
you can copy the whole lot of his Quartzes, as well as his Nova formulas,
into your copy of Fractint. Just make sure you save the formulas with their
extension .frm. (Windows sometimes adds a .txt extension to mess things
up.) Also make sure you get his pars, too, saving them with the extension
.par. His are REALLY GOOD.

I hope I am not being too confusing. Also, if you're interested in learning
about fractals, I would highly recommend going to Paul's pages. Besides
being the best gallery on the net (IMHO), he has a lot of really good
information on learning about fractals and looking for fractals with
Fractint.

If you're having trouble, just send in more questions; I will try to answer
them, but there are people on this list who are a lot better than me at
answering them in a comprehensible manner, giving specific instructions,
etc. Peter

About 5 minutes ago I heard a news bit that IBM has made another advance in
storage capacity for hd ~ 11 gig per sq inch (or ~ 11 gig/inch). This will
be available around 2001.
So...what can be done using fractals with this much storage space?
Nothing per se, but but but - certainly beats 640K.
Just passing this on...

Hi fractinters,

Got some problems with sexuality? I hope not..

One nice (my opinion) animated fractal, for man_only!!. Woman may find it
boring, boring...
Let it run with Fractint and DTA (Dave's Targa Animator)..

Have fun..

Beth....

Here is what I do and it works most of the time.  I run under win95 so ole
works for me and I can cut and paste.....

1.  Highlight the par portion of the information.  It usually starts with a
name, some information and then the word "reset."  It ends with a }
character. Make sure you have the whole thing highlighted.

2.  Copy what is highlighted.....different programs put the copy function
in different places.....in my Eudora I go to "edit" and get a drop down
menu that shows the word "copy".....click on copy.

3.  Open a vanilla flavored text editor like notepad (I know, I know, use
PFD).....one which doesn't add word processing characters......find the
paste utility (usually in a drop down menu either under "file" or "edit" at
the top of the screen) .......click on paste.....the whole par should now
be pasted. Make sure there are no spaces between lines or any extraneous
characters from your mail program. Save the file as anyfilename.par....make
sure you use the three letter extension.  The par file can be put
anywhere......I have a separate folder under my fractint folder for pars.

4.  The formula for the par must be saved separately, if it is not one of
the fractint standard formulas using the three letter extension .frm.
Copy and paste it, as above, into a separate file.  Then name the formula
file whatever (exactly) it says in the par file.....take a look below and
you will see that the par I sent "looks" for the formula

formulafile=contest4.frm
formulaname=contest4

Put the formula file (in this case contest4.frm) into the same directory
(folder) as fractint...NOT with the par if the par is in a different folder.

The par portion of the pars can be put into a single file, one par after
another. I suppose the formulas could be put into a single file too, but
then you would have to go to the trouble of editing the par to "find" the
formula properly.

To make a par to send to others......that's easy

1.  While you are in Fractint....and looking at that dynamite image you
want to share.....hit the "b" key.  You will get a screen you can change.

2.  Up on the very first line figure out a filename .....I use angela.par
or examples.par or something like that....don't forget the .par part

3. On the second line...enter some sort of name for your image....pretty
much anything appears to work........then on the 3rd line you can enter a
short explanatory note, if you like...but that's optional....hit enter.

4.  Exit Fractint and get to wherever your editor is....mine is in win95 so
I return to that.....open your editor (notepad for me). Open the file you
just made.....say angela.par.  You will see the par information
there....just copy it and paste it into an email for us!!!! Taaaaaaaa
Daaaaaahhhhh!!!!

It's a lot easier to do than explain. Hope this helps.....

Angela

Beth....

It occurred to me that maybe you didn't have the contest4.frm....so here it is

contest4  {; Kerry Mitchell
      ; slightly optimized version of Contest formula
         z=p1, c=pixel:
         z2=sqr(z), z=z*z2+c*(1+z-z2), |z| <= 4
         }

You will need that for some of my pars.

An alternative, is to use a more powerful image manipulation toolkit
like netpbm.  However, the power of netpbm comes at the cost of some
complexity.  Here's an example of how you would stitch together a 4x4
tile set:

    # assemble column 0
    giftopnm frmig_00.gif > tile0.pnm
    giftopnm frmig_01.gif > tile1.pnm
    giftopnm frmig_02.gif > tile2.pnm
    giftopnm frmig_03.gif > tile3.pnm
    pnmcat -tb tile0.pnm tile1.pnm tile2.pnm tile3.pnm > column0.pnm

    # assemble column 1
    giftopnm frmig_10.gif > tile0.pnm
    giftopnm frmig_11.gif > tile1.pnm
    giftopnm frmig_12.gif > tile2.pnm
    giftopnm frmig_13.gif > tile3.pnm
    pnmcat -tb tile0.pnm tile1.pnm tile2.pnm tile3.pnm > column1.pnm

    # assemble column 2
    giftopnm frmig_00.gif > tile0.pnm
    giftopnm frmig_01.gif > tile1.pnm
    giftopnm frmig_02.gif > tile2.pnm
    giftopnm frmig_03.gif > tile3.pnm
    pnmcat -tb tile0.pnm tile1.pnm tile2.pnm tile3.pnm > column2.pnm

    # assemble column 3
    giftopnm frmig_00.gif > tile0.pnm
    giftopnm frmig_01.gif > tile1.pnm
    giftopnm frmig_02.gif > tile2.pnm
    giftopnm frmig_03.gif > tile3.pnm
    pnmcat -tb tile0.pnm tile1.pnm tile2.pnm tile3.pnm > column3.pnm

    # assemble final image
    pnmcat -lr column0.pnm column1.pnm column2.pnm column3.pnm \
    | ppmquant 256 | ppmtogif > huge.gif

As you can see, the command sequence is lengthy and tedious, which
makes it a great candidate for a batch file.  Since fractint's b
command always puts the savename frmig_NM in the written par file
the only variation on this for different images is the name of the
output file which can be made a parameter in the batch file.

Hi Fractintiers,

Here is a sample using Paul Carlson's 3D Balls formula.
I thought I'd just take a simple pan down to elephant row
and see what the balls would look like in one of the spirals.

Well...

One should be cautious when using this formula, as this
example shows. You can get some images that should
not be viewed by humans.  I'm holding the copyright tightly
on this one, since it should not be shown to non-fractal
types***. They just won't understand and might call the
guys in white coats.  ;-)

*** For a discussion of fractals and personality types,
see recent Fractal art list postings.

This might be a time to ask Tim what his view would be on posting
uuencoded gifs to the list.  I am thinking of very small ones, with
viewwindows at about 10.  Depending on the complexity of the image, these
would be around 10K or less.  In cases like Peter's Turnz and Coilz, this
might be the only way to show what was aimed at, and indeed, if Peter can
re-generate Turnz and Coilz in the small size, it may help others to
figure out what is going wrong.

Unless and until Tim says, we should not post any such gifs to the list,
but it is something to consider.

Peter,

If you can generate Turnz and Coilz in very small size, I'd like to see
them and you could send them directly to me.

For various reasons, the consensus was in past discussions to put the
image on a web page and post a URL rather than sending the image directly.

We should put these on a web page.  It would be an extra step, email
an attachment to me or someone else with room on a page. Then in
a day or so it would be up and referenceable.

I recommend no gifs to the list... there are about 25% on this list that
would be upset.

I have little room now with the contest but if I redirect the three winner
images
to Paul Lee's page, there is about 1 Meg at my geocities site.

I have been thinking of posting some of the hard to transfer par and frm
files from this list on my site in zip form, so that some who have even
more difficulty getting them to work than I can get them easily.  The
digest does not help in this, since the difficulties often mean editing the
files as posted.

Geocities is free, so if any of you 'out there' want to get a page....
It is rather easy if you have a PC, Win95, and Netscape (not Explorer!!).
Dunno about other platforms.

Jay,

                                                            ^^^^^^^^^^^^^^
I'd like to comment on this, although it's only peripherally on-topic.  I
assume what you're referring to here is GeoCities' EZ-upload facility,
where they state that it doesn't work with Internet Explorer.  (For you who
have never used GeoCities, the "EZ" here definitely applies: it makes
uploading files for your GeoCities web pages *very* easy.)

Although Internet Explorer 3 does not work with this utility, version 4
*does*.  So if you're using MSIE4, don't let that "Netscape only" bit scare
you away from using GeoCities.  They'll give you 3M of space for free, but
they'll insist on ads in your pages.  If you pay them $5/month, they'll
give you 15M of space and allow you to dispense with the ads.

Another peripheral comment

I have two sites at Geocities myself.....<<sigh>>.  You can get a site for
every email place you have...I have two providers (god forbid I should be
off the net for ONE second!!!)

I use ws_ftp95.exe to upload to Geocities and my other 3 sites (I know...I
know...I'm wierd) which is a great program and extremely easy to learn and
set up. It's available for free at www.nonags.com...THE place to find cool
freebies. One warning......Microsoft Front Page and Geocities don't
mix....so use another html editor.  If you've never done a homepage I have
a page devoted to the absolute basics of homepage making at

Well, I, at any rate, have got some problems with some of the sexual
innuendo, etc., posted to this list recently. I believe there are plenty of
chat groups on the net to satisfy this sort of need. And if by chance you
want the real thing -- why don't you check out

My sympathies......innuendo can be disconcerting.....but I'm sure you can
avoid all this stuff by merely deleting the emails with biological topics.
No need at all to sully yourself. Innuendo...like beauty...is in the eye of

I hacked a little M-set program to do this and the results are fairly
interesting from this first experiment... the possibilities are

Rich,

 - Here's a quickie idea... use the last iterate of each pixel to generate
 - texture coordinates (u,v) and then color the pixel by texture lookup.

Kai's Fractal Explorer (part of Kai's Power Tools) has an option to do this
sort of thing.  It uses the potential for one axis and field line angle for
the other.  Very interesting, but not as spiffy as one might expect.  My
main complaint is its field line resolution is limited, and becomes pretty
much worthless after a few zooms.

Hi Rich,

If you could explain to this forum how to specify the color of a pixel,
given most any other information about the point in question, it would
be a first. I have asked several times. I have some neato schemes
I code in C++ for my clunky Borland C++ 3.1 with slight graphics
support. (See DEEPZOOM for example, on my Geocities web page)
So I know c, z, iter and some other info which is special. Now how do
we specify color.  Remember, I still want to use Fractint's other support
such as period checking, escape detection etc.

Sorry, but you can't (yet) do it in fractint.  However, the topic of
using information from the iteration to give extra inputs to 24-bit
coloring algorithms has been discussed here at length.  I've proposed
replacing fractint's current "color = iteration" paradigm with the
idea of being able to write formulas to generate the color at each
pixel.  I think this is doable, but I don't really have any
environment in which I can compile 16-bit DOS apps to be able to add
this kind of support to fractint myself.  I think it will have to wait
until fractint is 32-bit app friendly or until I do more work on
hacking xfractint to work (stymied at every turn! :) properly in the
environments available to me.

Suffice to say that this particular kind of coloring is something
like:

    u = 1.0 + real(z)/|z|;
    v = 1.0 + imag(z)/|z|;
    color = texture[u][v];

To give you an idea of how it looks, take a peek at

Jay,

 - If you could explain to this forum how to specify the color of a pixel,
 - given most any other information about the point in question, it would
 - be a first. I have asked several times. I have some neato schemes
 - I code in C++ for my clunky Borland C++ 3.1 with slight graphics
 - support.

If you only want to specify a color index, you can see the example FRMs
posted here by Kerry Mitchell, Paul Carlson, and myself.  These show how to
write FRMs that use ordinary fractal types with new coloring techniques.
The one I posted has over 100 formulae  Since you can do this with FRMs,
you get to use periodicity checking, solid guessing, or whatever.

Of course, this only gets you as far as specifying the color index; you
can't hard-code the palette into the FRM, and right now FractInt is still a
256-color beast.  I have had good results rendering the same point with
different coloring methods, using entirely different palettes, and merging
them together with a graphics package.

I have looked at Paul's lately, since he has comments. Still not much help.
He uses z as a color index which is still unclear how that works.  I thought
z is a complex number which is used for periodicity checking, and in the
atan, summ, etc options.  If I use z for color index what are the rules. This
seem not to be written up in Fractint docs or frm tutor.

Where was this posted?  I have over 1000 posts to this list, most on a
server I can't get to at the moment. Even if I could, I need a reference.

Really, all these with color index?????  Unclear!!

That is not a problem to me, I have made very nice effects with 16 colors when
I have control of the color index.

Can you tell me what atan() does in Fractint?  In an equation frm, we can say

x = atan(z),

z complex and x complex. Is this a true complex atan?  If so and we can set
color index plus have periodicity checking, solid guessing, or whatever, then
I could make a true field line following image. Unlike the kludge I posted
earlier.

Thanks for replying,

Jay

Press "g".  Type "periodicity=0" and press RETURN.  Not easy to figure out,
it took me a while (a couple of years ago) to find this.

How big is it?
Also, not everyone has Linux and can handle tarred and gzipped files.
Where can these be obtained as plain zip files?
(Actually, zlib/libpng compiled into not just the libraries but also a

I haven't really used it myself yet, but Pov-Ray 3.0 allows one to use
image maps as texture maps in much the same way. In fact, you can muck
around with textures in the same way as pure colours, including gradations
from one to another. Actually, as soon as I've finished checking my mail, I
might just do that - use a fractal to specify a texture map that blends
between two other textures.

Okay, I did find it after all, and I might as well do what I said (the
colours are not the original palette). Even if you're not keen on these
fractals (and there are some types that leave me cold as well) you can

Hi Blake,

Good start, Blake. The bailout of 4 is modeled after the Mandelbrot set, no
doubt.
Don't be afraid to try larger values with new formula, lacking theoretical
analysis.
Also, if you increase the iteration limit you can get more detail around the
solid
part. Just a scientist view, not an artists.

Here is something I found lurking nearby.  As usual, a lot of my fractals blow
up,
catch fire or look like they are about to explode.  Hope this is not too hot
for
this list.  :-)

All three have "reset=0" which is damned strange. Have you tried changing
it to "reset=1960"? Are you even using the latest Fractint, 19.6?

Ah. Once again, someone has whet our collective appetite and tantalized us

no pointers even for more information.....

Subject: (fractint) Binary decomp...256 decomp...*continuous decomp?*
Date: 31 Dec 1997 03:34:36 -0500 (EST)




Continuous decomp: For every iteration, save a bool for whether it was
above or below the X-axis (i.e. imaginary part was positive or negative)
at that iteration. At the end, use the most recent bool thusly: set q =
0.5 if it is true (was negative), 0 otherwise. For the second last bool,
add 0.25 if true. For the next, 0.125, Continue to desired precision.

This results in a number between 0 and 1 that oughta be the external angle
passing through that point, or for set members, internal angle. Use it as
you wish, perhaps to index into a color map.

The list went down, was working again, then I got permission denied
tonight before midnight. But I'd sent a whole batch, and all the ones
AFTER midnight made it. Is it some kind of hour limitation? They've made
it off-limits during some sort of peak usage hours that end at midnight?

I think such a thing is bloody ridiculous, and that failing to inform
people about it is even more ridiculous. If there are going to be hours
when the list is open and hours when it is closed, please post them in
public on the list so that we KNOW about it instead of having to guess
based on when it lets us post and when it tells us we're not allowed...

I've had the same problem with accented a's.... I *think* the DOS editor
that is in windows will allow you to edit the a's, open a dos session, type
"edit" and you will be able to load the notepad file edit and save it out
again.

*If* you have MS word then just paste the par into it and save out with a
text only option and the a's will be gone! Other WP may have the same result
if saved as text only...... but *not* notepad :(

STOP PRESS: Just had another though & it checks out ok... Wordpad  will do
if saved as text, should be in your 95 accessories folder :)

Yup, you are absolutely right... The pars are regenerating miles away from
the area I captured, they were sections within the area you spotted :)

Can't think why they go screwy though, first time this has ever happened to
me :(


I am using 19.6, the image I started with was one of mine from the FC2E CD,
can't remember which version although all three were generated from it...

<URL: ftp://ftp.cs.washington.edu/pub/ntemacs/latest/i386/utilities/win95/>
contains EXEs for Win95 and WinNT for: gunzip 1.2.4, gzip 1.2.4, and
tar 1.11.2.  Navigate two directories up from that URL and you'll be
pointed at gzipped tar files for emacs on 95.  If you like using emacs
as an editor, but you've got a win95/NT machine, then you'd probably
like that distribution.

If you are already familiar with how these tools work, then that should
be enough.  If not, then they are similar to zip (not winzip) in that
they are command-line oriented tools.  Since they are GNU tools, you
can give them '--help' as a command line argument to see what arguments
they take and their command-line syntax.

You can also get gzip directly from prep:
<URL: ftp://prep.ai.mit.edu/pub/gnu/gzip-1.2.4.msdos.exe> (gzip can
compress as well as uncompress; gunzip is just a convenience).

prep is the master source location for all GNU and Free Software
Foundation source distributions.  In fact, I have wondered why
fractint didn't use the gmp library for its arbitrary precision
support, but I can't complain about the feature :).

One need but ask...
an archie <URL: http://www.amdahl.com/internet/archieplex/form.html>
search for "netpbm" zip files turned up:
<URL: ftp://ftp.uni-mannheim.de/systems/windows/win32/winnt-local/>
Which contains "netpbm-e.zip" for the executables and "netpbm-s.zip"
for the source.

The definitive netpbm distribution is at
<URL: http://wuarchive.wustl.edu/graphics/graphics/packages/NetPBM/>,
but netpbm as a collective distribution hasn't been updated since 94.
There are various places around that have archived additional patches
and updates.  For instance, the png home page <URL:h
ttp://www.cdrom.com/pub/png/> has pngtopnm and pnmtopng utilities for
converting to and from pnm files to png files.

I think the trick is to get the index you want into z, since that's
something you can assign to (and you can't assign to iter), and then
use the appropriate coloring method to get the z value used as the
index.  For instance, you can assign something to z and then use
outside=real to use the real component of z as the index.  Similarly,
you can use outside=imag outside=mult outside=summ outside=atan, etc.
For the inside you can use inside=zmag.

for the New Year, I think I suceeeded.  They are posted at

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

There are several new color maps that go along with the images
themselves....and a pair of rose colored glasses especially for Jay!!!!!
Grand Pooh Bahs definetly need fractalspecs!!!! (dontcha love double

Can we have a quicky contest to see who finds the first decent fractal
football???  Seems appropriate for the day ahead.....

Anyway...may you and yours have the best year ever

Here is my Fractint wish list for 1998....

1.  Another fun contest
2.  Winfract that runs under NT with all the groovey DOS features (I'm
stuck with NT at w*rk)
3.  A better understanding of math so I can do some formulas or at least
appreciate the ones you all make
4.  Continued fun on the email list and maybe an IRC fractint chat forum
.....let me know if anyone is interested

<<hugs>> to all...and a wonderful new year

Subject: Re: (fractint) Binary decomp...256 decomp...*continuous
Date: 31 Dec 1997 10:37:56 -0600

Paul,

 - Continuous decomp: For every iteration, save a bool for whether it was
 - above or below the X-axis (i.e. imaginary part was positive or negative)
 - at that iteration. At the end, use the most recent bool thusly: set q =
 - 0.5 if it is true (was negative), 0 otherwise. For the second last bool,
 - add 0.25 if true. For the next, 0.125, Continue to desired precision.

Y'know, I tried exactly this, based on the description of it in Peitgen et.
al.'s _Chaos and Fractals: New Frontiers of Science_.  And do you know
what?  I couldn't get it to work for the M-set.

So I tried it with Julia sets.  And what I discovered is that it works as
long as the imaginary component of C is zero.  Then it works spectacularly
well.  But as soon as the imaginary component becomes non-zero (as it does
for most points in the M-set!) then it stops working and you start seeing
all kinds of weird hyperbolic-like errors.  Interesting, but not right!

If you have successfully made this work, even in custom code, I'd love to
see it.

Subject: Re: (fractint) another 24-bit coloring idea
Date: 31 Dec 1997 15:23:28 -0600

Jay,

 - I have looked at Paul's lately, since he has comments. Still not much help.
 - He uses z as a color index which is still unclear how that works.  I
thought
 - z is a complex number which is used for periodicity checking, and in the
 - atan, summ, etc options.  If I use z for color index what are the rules.
   ^^^^^^^^^^^

This is the key.  If you set your outside coloring to "real", you can write
the formula so that, at some point, you stuff a new value into z.  I do it
on the last iteration, so I can still reap the benefits of periodicity
checking on z.  Other possibilities are to use decomp=256, and then put a
new value into z before bailing out; this is the easiest way to get an
"angle", rather than try to use atan() in the formula itself.

 - This seem not to be written up in Fractint docs or frm tutor.

No, this seems to be something of a secret. :)

 - Where was this posted?  I have over 1000 posts to this list, most on a
 - server I can't get to at the moment. Even if I could, I need a reference.

For the next few days, you should be able to retrieve my collection from
this URL:

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

I say for the next few days, because very soon that entire site will be
moved to fractalus.com.  The ZIP file contains a FRM with all the coloring
algorithms.  Most of these are my own variation on the orbit-trap type.
All are extensively commented.  There's also a PAR file with a "starter"
PAR for each formula, which will automatically set the outside coloring
options and force floating-point math.

 - > you get to use periodicity checking, solid guessing, or whatever.
 -
 - Really, all these with color index?????  Unclear!!

Meaning that all these still work, even when you're writing a FRM which
specifies a color index.  If you use w instead of z as your iterating
value, as some have done, you lose periodicity checking--and unless you
continually change z so it is non-periodic, forgetting to turn periodicity
checking off will make all points appear "periodic".  So I always use z as
my iterating value.

 - That is not a problem to me, I have made very nice effects with 16 colors
 - when I have control of the color index.

Yes, well, it depends on the effect. :)

 - Can you tell me what atan() does in Fractint?  In an equation frm, we can
 - say
 -
 - x = atan(z),
 -
 - z complex and x complex. Is this a true complex atan?

The definitions for how FractInt computes complex trig functions are listed
in the help, linked from the help for type "formula".

 - If so and we can set color index plus have periodicity checking, solid
 - guessing, or whatever, then I could make a true field line following image.

I would very much like to know how this is done, I've been trying for quite
some time.  I have some ideas for fractals which require access to field
line data, and I can't seem to make it work.

Blake,

 -   Ok... i missed it for Christmas, but my birthday is coming up soon and
 - I'm hoping... Would it be better to get a Pentium 200 MHz motherboard
 - and leave myself with this old crappy monitor, or a Cyrix 166+ and get a
 - 4mb vram card/monitor?

Depends. :)  A 200MHz Pentium, with properly optimized code, will outrun
the Cyrix 6x86 PR166+ by a factor of... oh, about 9:1.  As in, nine times
faster at certain FPU-based FRACTAL calculations.  For everything else,
especially 95% of other apps, the Cyrix will perform comparably with a
166MHz Pentium.  So there's something to be said for having a 17" monitor
with a card that will crank out a 1600x1200 display mode.

The choice is yours, but personally I'd go for the speed.

For your end, its best to ask compuserve technical support since its
their software you're using and their software that's putting
everything in printed-quotable.

I don't know of anything that can be done at the list end of things.

I'd recommend upgrading your monitor/video card, since that
technology becomes obsolete at a slightly slower rate than
the chipset technology does.  Just my two-cents worth;
other factors may outweigh this one!  Cheers, New Years!!!

Friends,

A new exhibit at MOCA: Museum of Computer Art features some
30 fractals by Sylvie Gallet at http://www.dorsai.org/~moca.

Also included are fractals by don lebow, Caren Park and Lee Skinner.

Commentary and biogaphical notes provided. Lots of non-fractal
computer art as well, including raytraces, enhanced photography, etc.

Enjoy and Happy New Year!

Date: 29 Dec 1997 19:24:09 -0500

    I've noticed that fractals take up a lot of $pace in their default
format, gif, coming from fractint. I have found a shareware utility, Graphic
Workshop (get it from C|NET's www.download.com), to convert from gif to
jpeg. It's very little trouble and reduces the $ize from 10-50%. I changed
my fractals to jpeg and had enough $pace saved to make real thumbnails...
and still keep the size below the old gif size. (Of course, the thumbnails
look awful, but they're small... <10k apiece.) This will probably appeal
most to those $pace hogs out there who use multiple homepages... you know
who you are. :) -Blake

Make that color = white if real(z)>0 else color = black.

I think the code should look like the following, but there
is something wrong.  You should see MSet in black,
and binary decomp in yellow and blue.

Well, my ISP has been unreliable today but I was just able to get thru.
Any browser should do the trick. They tell me that Bell Atlantic is
putting in new fiber optic lines to them but who knows. Give it another try.
Thanks.

    I just got finished redoing my fractal web pages at
www.connectu.net/bhyde/fractal.htm. The changes were mostly aesthetic, like
adding a background and some links. Which is why I'm writing this wonderful
fifth letter in three days (the lurker rises! :) I would very much like to
link to everybody else's pages... I have one for Wizzle, Jay, and Sylvie.
Must have more! More! Please send them to my email, [e-mail],
instead of the list. Spam, you know. Or send 'em to the list. I take no
responsibility. :)

We have subscribers all over the world, some of whom have expensive
internet access. For this reason, binaries should not be posted to
the list, and messages should be kept short, with no more quoting
than is needed to provide context for a response. List posters should
also be careful about posting personal chatter that might better be
sent directly than via the list. The goal is to minimize off topic
bandwidth and maximize useful on-topic information. Generally folks
have done well in this regard.

Even though thumbnail GIFs are small, allowing GIFs attached to
messages is a Pandora's box I don't want to open <g!>

The clicks are, I think, the monitor switching between text and graphic
modes. It's annoying and ugly, but that's what it is.

Also, can anyone tell me how to make it so I can _really_ reply in Outlook
Express? I have to do this stupid new message, and then it plugs in another
(fractint).... *mutter*

Oh, Bill, thanks for the link. :) I haven't added it yet, but I'm getting
there.

    I added your link, Bill. Now I'm going to sink back into Lurkerdom until
1) someone gives me an url, or 2) I have a decent par. Of course, I might be
tempted to answer questions that I know the answer to. :) I started to get
worried when I noticed that my posts are about equal to Wizzle's, but I
really got scared when they outnumbered Jay's. :) C u when I next post (in
another coupla months, probably). -Blake

ps. Can anyone tell me how to set a sig in Outlook Express?

Subject: (fractint) Formula Question
Date: 30 Dec 1997 17:04:40 -0500

    When I write formulas, I usually come up with things that can't possibly
have decent images buried in them. I have, at last count, 20 "duds" that are
just straight bars or dots around the screen. Is there a good tutorial on
formula writing, or can somebody give me some tips? (Not _the_ tutorial, I
understand the workings of the parser, I just can't seem to get the
aesthetic results I want.) I know at least five people here whose formulas I
very much envy, but I'm not naming names. :) Is it a geometry thing? Or
Trig? *sigh*

I don't think that's enough links, Paul. I mean, what's 500 or so? <notes

Reading this, I noticed that it came across all wrong... it sounds "mean."
it was supposed to be humor. *mutters about needing sleep*
