Hi Tony,
I enjoyed making the program because I like a challenge, if you (or any-one
else) have an idea I 'd be happy to hear it.
I was also wondering how many duplicates you found, I only found jewels2.map
and wizzle18.map, these are both in fracxtr6.zip (I don't make my own colour
maps because I am no good at it at all)
From,
Rupert

Subject: (fractint) Fractint 20.0.6 now public
Date: 01 Feb 2000 23:20:15 -0600
Fractint 20.0.6, the developer version 20.0 patch 6, is now available
via anonymous ftp at ftp.fractint.org/fradev.zip. We intend to release
most, if not all, of the developer versions from now on.
This file has only the executable, a PAR/FRM file by Sylvie Gallet,
and a read.me. It's not a complete distribution - you still need the
version 20.0 files.
Please don't upload this anywhere unless you are willing to keep it
current. These developer versions can change very fast! Also, this
is not an official release, but a bleeding edge version, so be careful.
On the other hand, it has bug fixes, so maybe it is more stable
than a release version :-) Our official position is that there is some
risk in using a developer version for serious art, because we may
make changes that are not forward compatible. Of course we try to
avoid this.
The fractint.org ftp site also has the developer diff files and the
version 20.0 release package and source. This web site is not
intended to replace Noel Giffin's wonderful spanky.triumf.ca; I
expect Noel will have the developer's executable up there soon also.
This version is mostly bug fixes (see the what's new). However
Sylvie Gallet asked us to add the center/mag parameters as
formula parser constants. We accomodated her without exactly
understanding why she wanted this. An example file is included in
fradev.zip. It looks for all the world like a fractal reflected in a lake.
Ms. Gallet never ceases to amaze me :-)
As we get more organized we'll get Xfractint and an integer-free
version posted also.
Enjoy!

Subject: (fractint) FOTD, 02-02-00 (Mathematical Gills) (c)
Date: 02 Feb 2000 01:35:49 -0500 (EST)
FOTD -- February 02, 2000
Fractal enthusiasts and visionaries:
I've seen no signs of life from the philofractal list in over 24
hours. My own test messages are bouncing back. Since this is
the start of a new month, I suspect that the list went extinct
as January ended -- and just when I was ready to reveal the
secrets of the universe. If so, may philofractal rest in peace.
Hopefully the fractal-art and Fractint lists won't go the same
route.
Today's fractal takes the whimsical formula 100(Z^100)-(1/Z)+C
and does something interesting with it -- interesting and fishy.
The pattern around the central midget reminds me of a shark's
gills, so I named the picture "Mathematical Gills". To achieve
the effect of gills, I set the outside to summ and made a slight
adjustment to the color palette.
The image is another one that should be rendered at a resolution
of at least 1024x768. This should be no problem, since the
parameter file runs in 2-1/2 minutes on a p200 Pentium. But if
this is still too slow, the image has been posted to:
<alt.binaries.pictures.fractals>
and to:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
from where it may be downloaded in a minute or so.
The fractal weather today was partly cloudy and breezy, with a
temperature of 34F (1C) which kept the fractal cats safely
indoors.
Our friend Percy is still in his strange room, decorating the
walls with pictures of hypersolid geometric figures. On the
east wall he has painted a 3-dimensional picture of the next in
the series of the six regular four-dimensional polytopes.
I call this one the hexadecahedroid. (Perhaps hexadecatope
would be more accurate.) It is the reciprocal of the hypercube
and consists of 16 tetrahedral cells, 32 triangular faces, 24
edges and 8 vertices. Its analog in three-dimensional space is
the octahedron.
To form the hexadecahedroid a given distance is laid off in both
directions on each of four mutually perpendicular lines
intersecting at a single point. The eight points so obtained
mark the vertices of the figure.
The three-dimensional projection of the hexadecahedroid is a
tetrahedron with a smaller tetrahedron within it. The smaller
tetrahedron is rotated so that its four faces face the vertices
of the outer tetrahedron, and three lines are drawn from each
vertex of the outer tetrahedron, connecting to the three corners
of the facing face of the inner tetrahedron. A set of
tinkertoys is a great help in actually constructing and thereby
visualizing these projections.
Tomorrow, Percy will decorate the west wall of his hyper-room.
He will do it with a 4-D figure that has no analogous figure in
3-space. Lots of luck to our Percy in his abstract endeavor.
I see it's time to shut down. Until then, take care, and rest
easy.

Subject: (fractint) Fractal Fracture
Date: 02 Feb 2000 13:10:35 GMT
If you draw the fractal resulting from Z^2 + C, you get the standard
Mandelbrot image. If you draw Z^3 + C, you get the cubic Mandelbrot. But if
you draw Z^2.5 + C, you get an image with a multitude of fractures in it.
The reason is fairly straight forward. The function Z^2.5 has multiple
solutions, so FractInt must arbitarily pick just one answer. It is not
possible to do this so that the resulting "function" is continus; there are
so-called "branch cuts", and these create the fractures in the image (which,
being a factal, propogates them everywhere!).
What I would like to do it change the way FractInt selects the solutions,
i.e. move the branch cuts around. Of course, to do this requires fiddling
with the source code... or fancy formula work. And that's why I'm typing
this: I was wondering wether anyone can show me a formula with a parameter
to move the branch cuts.

I'm not sure if you can call it the same formula, but the expression
(-Z)^2.5+C draws an entirely different figure. With exponents between
1 and 2 this formula creates an entirely new type of Mandeloids. Try
the attached formula.

Jim,
The philofractal list isn't dead, yet. My previous employer asked me to
remove the list from his server, so Monday I did that. Since then I've
managed to spend more than twelve hours in the hospital over two days, so
my ability to test the functioning of the new list (at
philofractal@lists.fractalus.com) has been limited.

Date: 02 Feb 2000 19:50:24 -0800
Hello folks..
I used to have a quirkly little program that produced
batch files to render animated sequences using fractint-produced
gif files as input. Theoretically, anyway.. In practice, you
usually have to manually tweak the .PAR file produced in order to
get satisfactory results.
It's idiosyncrasies aside, I have a keen desire to find this
little utility again, and I'm embarrassed to admit that I can't
find it anywhere. Can anybody offer me some assistance in this
regard? Or point me in the direction of a similar utility?
(Barring the loathsome "FILMER", of course-- a pox on it's
microencephalic author!)
Thanks,
LT

Date: 03 Feb 2000 01:29:25 -0500 (EST)
FOTD -- February 03, 2000
Fractal enthusiasts and visionaries:
Every now and then a fractal comes along that is simply
dazzling. Since today's fractal is one of those dazzlers, I
named the picture "Dazzling Midget".
The picture gives the impression of multiple layers. This
impression is a total illusion. The fractal is a purist one,
with the outside colored by the flat equal-iteration-band method.
The formula behind the picture is the M-Mix4 calculating
2*(Z+Z^(-100))+C. The parameter file is relatively slow, taking
15 minutes on a Pentium 200mhz. A far more efficient way of
viewing the dazzling image is to download it from:
<alt.binaries.pictures.fractals>
or from:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather was sunny today, but breezy and quite cold.
The fractal cats didn't even think of going outside into the
temperature of 27F (-3C).
Our friend Percy Smedley is still busy painting a picture of the
next regular four-dimensional figure into the volume of the west
wall of his hyper-room. Unfortunately, after a hectic day I'm a
bit too mentally congested to think in four dimensions. But I
will say that the name of the next figure is the
icosatetrahedroid, or the icosatetratope, and it consists of 24
vertices with 6 octahedra and 8 edges at each vertex, 96 edges
with 3 octahedra at each edge, 96 triangular faces with 2
octahedra at each face, and 24 octahedral cells. It corresponds
to nothing in 3-D space.
If I regain my mental prowess, I'll further describe this figure
in tomorrow's FOTD. If I don't regain my prowess, no one will
notice the difference. Until then, take care, and be faithful
to your fractals.

Would this be Par2bat? The FracXtra distribution contains 3.1 - maybe
there's a later version (if there is: <luser>ME TOO!</luser>.

The name of the program that I'm scrambling after is FA.EXE,
although ANIFRA would rate a close second.
Everything thing after this sentence is redundant and repetitative...
Hello folks..
I used to have a quirkly little program that produced
batch files to render animated sequences using fractint-produced
gif files as input. Theoretically, anyway.. In practice, you
usually have to manually tweak the .PAR file produced in order to
get satisfactory results.
It's idiosyncrasies aside, I have a keen desire to find this
little utility again, and I'm embarrassed to admit that I can't
find it anywhere. Can anybody offer me some assistance in this
regard? Or point me in the direction of a similar utility?
(Barring the loathsome "FILMER", of course-- a pox on it's
microencephalic author!)
Thanks,
LT

Hello,
I would like to create my own formula that is based on the algorithm
newtbasin for finding the roots of z^3 - z. The pixels should be
coloured according to which root the iterates converge to.
How do I code this colouring of the pixels?

Larry,
- I used to have a quirkly little program that produced
- batch files to render animated sequences using fractint-produced
- gif files as input.
I believe I have this program, but I can't locate all the included files
for it. However, Spanky appears to have a later version, called FAE:

This should be what you're looking for.

Date: 04 Feb 2000 01:10:11 -0500 (EST)
FOTD -- February 04, 2000
Fractal enthusiasts and visionaries:
When I saw today's fractal midget, I thought how crazy the
coloring is. Right then and there I named the picture "Lente
Loco".
The image results from adding a tiny bit of Z^3 to Z^2 then
adding C. The parameter file is rather slow, making a download
of the image the better choice. That image can be found at:
<alt.binaries.pictures.fractals>
and also at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather was cloudy and cold today, with a few
flurries of snow and a temperature of 30F (-1C) that kept the
fractal cats Thomas and Tippy indoors.
Yours truly, the fractalist, had good intentions about
describing in today's FOTD the fourth of the six regular 4-D
hypersolids. But due to a virus bug of some sort that has left
me with almost no energy, I'll have to put it off until
tomorrow, and humbly seek forgiveness for my tardiness.
Until then, take care, and never give up fractaling.

The image was simply beautiful. More than makes up for a lot of mediocre

Date: 04 Feb 2000 16:17:42 -0200
Hi. I deicided to try writing some formulas, and did two very silly ones.
Nothing specila, but I zoomed in a bit in one of them. The strange thing was
that I couldn┤t cycle the colors anymore. Is it a problem with fractint or
does it have anything to do with my formula (although I cna┤t imagine why).
I saved the parameters and the formula and restarted fractint, calculated
the image again, and the problem is still there. I┤m sending the pars to see
if anybody can reproduce the problem. I didn┤t try with version 20.0 (it┤s
zipped somewhere in the dark places of my pc), only with version 20.0.6.
Yes, that was it.

Here is the Sylvie Gallet's par/frm file included with the developer's version of fractint.
This won't work with version 20.0, you need 20.0.6.
The images are quite different than anything fractint has done before. Note the
variables center, magxmag, and rotskew. These are new predefined constants that
hold the center/mag zoom coordinates.

Date: 05 Feb 2000 01:39:52 -0500 (EST)
FOTD -- February 05, 2000
Fractal enthusiasts and visionaries:
I named today's fractal picture "Art Nouveau Midget" because it
reminds me of the curvilinear art style that was popular around
the turn of the last century. It is the third in the present
series of spectacular midgets.
How long can I keep the streak going? I haven't the slightest
idea, since the quality of the FOTD images is largely a matter
of good luck in searching. The formula behind the image is
Z^(-1.05)-Z^(1.05)+C, an expression that I entered on a whim and
examined with more intuition than logic.
The parameter file runs in under four minutes -- still slow
enough to make the download preferable. That download can be
found at:
<alt.binaries.pictures.fractals>
and at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
Happy downloading . . .
The fractal weather today was cloudy with off and on flurries of
snow, amounting to about 1cm. The temperature of 36F kept the
cats indoors.
Our friend Percy Smedley is still puzzling over that four-dimen-
sional figure painted into the surface volume of his west wall.
The object, if that word can be applied to a 4-D thing, is the
fourth of the six regular 4-D polytopes. The monstrous thing
consists of 24 octahedral cells, 96 triangular faces, 96 edges
and 24 vertices.
The three dimensional projection, which resembles an octahedron
filled with a network of distorted octahedra, is too complex to
describe in detail. To form the figure, a hypercube must be
inscribed in a hypersphere, and then the centers of the eight
cubical cells of the hypercube must be projected onto the
hypersphere. The 16 vertices of the hypercube plus the
projections of the centers of the eight cells of the hypercube
form a network of 24 points on the hypersphere. These 24 points
are the vertices of the 24-tope, the icosatetratope, the fourth
of the six regular 4-D hypersolid polytopes.
Curiously, this method also produces a regular figure in two-
dimensional space, where it results in an octagon, but in three-
dimensional space as well as all spaces higher than four the
figure that results is not regular.
Having decorated four walls of his room, Percy is still not yet
finished, for he has two more walls to decorate -- the in wall
and the out wall. He will decorate his in wall with a picture
of a hecatonicosatope, which I will make a brave but futile
effort to describe next time.
Until that next time, take care, and don't try to visualize the
fourth dimension -- it's not a visual thing.

Here is a formula that will work for any (z-p1)*(z-p2)*(z-p3) =3D 0

In your case, the roots are 0, 1, and -1. I've added the par for the
"standard" z^3-1 =3D 0 equation (the roots are 1, -0.5 + i*sqrt(3)/2, and=
-0.5 - i*sqrt(3)/2), along with the par using the built-in newtbasin type=

Date: 06 Feb 2000 01:53:26 -0500 (EST)
FOTD -- February 06, 2000 -- Rating (6)
Fractal enthusiasts and visionaries:
Starting today I will rate my Fractal of the Day efforts on a
zero-to-ten scale, and include the rating in the FOTD header.
By doing this I will give the fractalists who are pressed for
time a chance to decide if in my opinion the image is worth the
effort it will take to view it. It will also give the FOTD
readers a chance to see how my opinion of my own work compares
with their opinion of my work. Most fractals will rate some-
where in the center of the scale. It's unlikely that I'll ever
achieve a rating of 10, and hopefully I'll never deserve a zero.
Today's fractal, for example, I will rate a six, which means I
consider today's image to be just a little above average.
The scale is roughly as follows:
0 -- Totally worthless
1 -- Very poor
2 -- Much below average
3 -- Below average
4 -- A little below average
5 -- Average
6 -- A little above average
7 -- Above average
8 -- Much above average
9 -- Outstanding
10 -- The best of all time
Today's midget fairly sizzles with energy, so I named the
picture "The Midget Sizzles". The formula combines portions of
Z^(-2.3) and Z^(-4.5). The negative exponents of the formula
are apparent in the spotty nature of the features of the image,
which lies at the tip of the negative tail of a far larger
midget in the parent fractal.
The seven minutes required to render the scene from the
parameter file make a download the wiser choice. And that
download can be found as always at:
<alt.binaries.pictures.fractals>
and at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather was settled, with bright sun and a
temperature of 34F (1C) that was too cold for the fractal cats,
who have a serious case of cabin fever.
Our 4-D friend P. Smedley has already decorated the north,
south, east and west walls of his room. The ceiling overhead
needs no decoration, and the floor beneath him is covered with
wall-to-wall-to-wall carpet, but he still has two blank walls
yet to decorate -- the in wall and the out wall. After much
thought, he decides to decorate the in wall with a picture of
the fifth of the six regular four-dimensional polytopes, a
hecatonicosatope.
The hecatonicosatope is a regular four-dimensional figure
bounded by 120 dodecahedra, 4 at each vertex, 3 at each edge, 2
at each face. Its 3-D projection is a dodecahedron with a
smaller dodecahedron at the center. In the exceedingly complex
network between the two dodecahedra are found 118 deformed
dodecahedra, as well as icosidodecahedra and the soccer-ball
figures composed of hexagons and pentagons.
At this point words fail me, but there is still one wall of
Percy's room that needs decorating and one 4-D regular
hypersolid yet to go. In tomorrow's FOTD I'll try to describe
the hexacosioitope.
I see it's time to shut down the fractal shoppe until tomorrow.
Until then, take care, and be carefree.

Date: 07 Feb 2000 00:50:21 -0500 (EST)
FOTD -- February 07, 2000 (Rating 5)
Fractal enthusiasts and visionaries:
Today's lush green fractal reminds me of a hypothetical scene on
the Emerald Isle. I named it "Erin" accordingly. The midget is
part of the fractal that results when the formula
-1*(0.1Z^2)+Z^(-3.2))+C is iterated. The blocky elements reveal
that a negative power of Z appears in the formula.
This fractal rates an honest 5 on my own rating scale, a small
comedown from the recent days' efforts. But then this is not
Lake Wobegon, and only half the images can be above average.
However, tomorrow is only 24 hours away, and the number of
fractals is transfinite, and the odds are 50 percent that
tomorrow's FOTD will be above average.
The parameter file runs in under 2 minutes, about the same
length of time it will take to get connected and download the
image from:
<alt.binaries.pictures.fractals>
or from:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather was much improved today, as a bright sun and
temperature of 35F (1.5C) knocked a few centimeters off the
depth of the snow pack. But it was still too chilly for the
fractal cats to venture out of doors.
When I last checked with our friend P. Smedley, he was still
working on the in-wall of his four-dimensional room, which is
directly opposite the out-wall. On the out-wall he painted a
picture of a hecatonicosatope, a regular four-dimensional
hypersolid bounded by 120 dodecahedron cells, 720 pentagonal
faces, 1200 edges, and 600 vertices.
Mr. Smedley became curious when he noticed that the sixth and
last of the four-dimensional figures, the hexacosioitope, is
bounded by 600 tetrahedron cells, 1200 triangular faces, 720
edges, and 120 vertices. The numbers of elements are in exactly
the opposite order of those of the figure on the opposite wall.
Then it struck him -- the two polytopes are reciprocal to each
other, just as are the cube and octahedron, and the dodecahedron
and icosahedron of our familiar 3-space. The centers of the 120
cells of the hecatonicosatope mark the 120 vertices of the
hexacosioitope, and the reciprocal relation is also true.
I'll further describe the last 4-D figure tomorrow, when Smedley
finishes his illustration; but for now, the fractal cats, who
have not the slightest interest in the fourth dimension, are
worrying me for their evening snack.
Until next time, take care, and if the fourth dimension is
impossible to visualize, why does the math work so well?

Subject: (fractint) Loading Formulae
Date: 07 Feb 2000 14:20:55 EST
I am using Fractint in Windows 98 and have very few problems struggling
along as a beginner/not-so-newbie. However I cannot seem to load any formula
other than those in fractint.frm.
When I use "t" to Load Formulae, the default is the fractint.frm Fractals
with no ability to access the *.frm Ihave loaded in the Frm directory. There
is no F6 toggle available. I have loaded sstools.ini properly and made the
modifications necessary to it to be able to access all the other features I
have tried.
Does anyone have any ideas, or am I overlooking something really simple?
Thanks,
Mitch Berger

Yes, very simple, indeed. press F6 when viewing the fractint.frm formulae.
BTW, I got a tremendously egoistic desire to send a nice RTFM message, but,
since Mitchell asked so politely, and we don┤t seem to have band-with
problems on this list (sofew posts lately), that I decided on being polite
again.
Jim, how do you color your FOTD? Do you use prefab maps or do you hit the
Enter key while in colorcycling? You got me inspired and now I┤m searching
for midgets all around. And your nice (is it really yours?) MandelbrotMix4
is so flexible, it┤s nice to use. Speaking of this formula, how do you
decide wich multipliers and exponents to use? I tried integers, square
roots, Pi, etc, and hoope to be in the right path. can you confirm that?
Just something els:
Where are you from, Mitchell?

While viewing fractint.frm my F6 key unfortunately does not do anything. The
legend reads "Use cursor keys or type value to make a selection. Press F2
for a description of the highlighted type". No call for the F6 key?
BTW I did look in the manual before writing. Just cause I don't want to
waste band width either.

Yor're trying to strike the F6 key while the 'select a fractal type' screen
is displayed. The F6 key does not work until you highlight fractal
type=formula, strike enter, and have the list of formulae in fractint.frm
actually on the screen.

and my previous one (19.6) work that way and _do_ have a call for F6, like
the one for F2. What┤s your verison??

I have no set means of coloring. To color the FOTD I sometimes use=20
every means available in the fractint program. On occasion I even go=20
so far as to post-process the image in a graphics program. At other=20
times I simply strike <enter> once or twice, and a great color=20
palette appears almost by magic.
Yes, I wrote the MandelbrotMix4 program, though the idea for a formula=20
that would automatically initialize Z to a critical point came from=20
Jay Hill of 'Fractoon of the Night' fame.
You're picking the multipliers and exponents exactly as I do. Many of=20
my choices are entirely whimsical. With a little experience, you'll=20
discover which values give the best results. BTW, when you get a blank=20
screen, don't give up. If it's a blank blue screen, back off an=20
outzoom or two. With this formula, the interesting part of the image=20
often lies far from the origin. If it's a blank black screen of=20
trapped points, raise real(p3) until something appears. Bracketing is=20
often necessary to find the optimal value here.

Subject: (fractint) FOTD, 08-02-00 (Liftoff [6]) (c)
Date: 08 Feb 2000 01:28:02 -0500 (EST)
FOTD -- February 08, 2000 (Rating 6)
Fractal enthusiasts and visionaries:
Today's fractal is a fractal. I make that rather redundant
statement because today's FOTD could be mistaken for a flight of
balloons that has just been released to celebrate some festive
event. Or it could be mistaken for a scene in the sub-atomic
world of quantum uncertainty. But it is none of these things;
it is in fact a fractal -- it is the Fractal of the Day for
today. I rated it a 6, which equals a little above average.
The image resembles swirling, twisting chains of rust-colored
spheroids floating before a pale yellowish-green background. I
named it "Liftoff". The formula behind the picture is number
six in my series of 12 MandNewt formulas, which once were
mysteries, but which I recently discovered are actually
variations of the Ikenaga function.
The six minutes it takes the parameter file to run is enough to
make a download the wise choice. The download may be found at:
<alt.binaries.pictures.fractals>
and at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today sent the melting of the ice pack into
high gear. The afternoon temperature of 50F (10C) cleared away
a few centimeters of the dead old snow, but there's still many
centimeters left to be eliminated.
Now that Percy Smedley has finished the decoration of his four-
dimensional room, there's little more to be said about his
efforts. I had intended on more thoroughly describing the
600-tetrahedral-celled figure he painted into his out wall, but
I had gone only a little way into the description when I
realized that a complete description would be inordinately
lengthy and nearly incomprehensible. I'll wrap up this current
multi-dimensional indulgence with some final words tomorrow.
Until then, take care, and see you in 24 hours.

Subject: (fractint) FOTD, 09-02-00 (Horns of Nimon [5]) (c)
Date: 09 Feb 2000 01:15:48 -0500 (EST)
FOTD -- February 09, 2000 (Rating 5)
Fractal enthusiasts and visionaries:
I recently missed a numeric curiosity that fell on February 2.
The numeric representation of that date is 2-2-2000 -- the first
day without an odd digit since 8-28-888. That's almost 1112
years.
Not being a numerologist, I have no idea of the importance of
this event, though I believe that in the occult world of
numerology the even digits are considered feminine and the odd
digits masculine. If you missed the big event, don't worry. It
was repeated on the 4th, 6th and 8th of this month, and will be
repeated on the 20th, 22nd, 24th, 26th and 28th, as well as on
many more days in April, June and August of this year.
Today's fractal however will not be repeated. If you miss it
today, there will never be another opportunity to see it. I
have named the picture "Horns of Nimon" after one of my favorite
Dr. Who episodes. It is a simple, symmetrical picture, with
little of the intricacy usually associated with fractals -- a
rather solemn, almost mystical image, created by number 11 in my
series of 12 MandNewt formulas.
The parameter file is rather slow, making the few minutes it
will take to download the image well worth the effort. That
image has been posted to:
<alt.binaries.pictures.fractals>
and to:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today was sunny but cold, with a temperature
of 32F (0C) that kept the fractal cats snug by their heaters.
After seeing the wondrous images our friend P. Smedley painted
into the six walls of his four-dimensional room, one might
wonder what figures Mr. Smedley's five-dimensional cousin, Q.
Smedley might paint into the eight hypercubic walls of his five-
dimensional room. In 3-D space there are five regular poly-
hedrons, and in 4-D space there are six regular polytopes.
Surely 5-D space must hold regular polytopes by the dozens.
But alas, only disappointment awaits in the dimensions higher
than four. Instead of increasing beyond limit, the number of
regular polytopes in all the higher dimensions is limited to
three. These are the analogs of the tetrahedron, the cube and
the octahedron. All is not lost however, for the sheer variety
of figures in these high dimensions more than makes up for the
lack of regular figures.
And now I must make up for a busy day by taking it easy for a
few moments. Until tomorrow, take care, and if you could live
in a space of any number of dimensions you wished, what number
of dimensions would you choose?

I have two questions for now:
why is default.map the default map? I mean, somedody must have seen in it
some quality that made it a good choice for a starting map. What quality is
it?
About the diffusion drawing method, it┤s kind of strage to me. If I
understood it right, it should give a precision equal to one pass linear
method, while still giving a good preview possibility (I mean you don┤t have
to wait the image to be complete to guess what┤s there and continue
zoomign). But sometimes it seems to calculate forever... When should I use
it (or don┤t use it)? I couldn┤t get anything different using the fill color
doodad, it says it works under t, be and d, and I only got interesting
results with tesseral method (and I love it!). Humberto, the diffusion
method developer, happens to be the person who introduced me to fractals,
and it┤s nice to have something more real in this virtual world that
fractint and the list seem to be...
Ok, that was it for today, I┤m making so many questions lately because I┤m
in vacations, and have time to further explore fractint. It won┤t last long,
unfortunately (only till 21st...)
Awaiting answers,
Fernando

The critical point of a formula is the initial value of Z that draws=20
Mandeloid fractals without perturbation. These are the Mandeloids with=20
the midgets. The expression Z^2+C has a critical point of 0,0. When=20
Z is initialized to 0,0, the true, unperturbed Mandelbrot set is drawn. =20
Other expressions, such as those determined by the parameters entered=20
into the MandelbrotMix4 formula, have non-zero critical points, which=20
must be calculated and applied to initial Z before the unperturbed=20
Mandeloid can be drawn. The M-Mix4 formula determines these non-zero=20
critical points and initializes Z to them automatically.

By bracketing I simply mean narrowing the search. For example if 100=20
is too small and 200 is too large, I try 150. If 150 is too large, I=20
try 125. If 125 is too small, I try 138. I continue narrowing the=20
search in this manner until I find the optimal value.

I believe it is the default because long ago in the misty past that

Thanks, Jim, now I know why the middle part of the formula exists, and
learnt a bit of English too.
Another question:
As mentioned before, hitting enter while color cycling brings up a new map,
I would say a rnadom one. but sometimes it seems that this map generation
follows some rules. Is this correct? What rules are those?

Fractal enthusiasts and visionaries:
Today's fractal is just good enough to rate a marginal 7 on my
totally arbitrary scale of fractal ratings. It was created by
the MandelbrotMix4 formula calculating the expression
Z^(-3)-Z+C. It's one of those combinations of parameters that
appears too simple to create a worthwhile fractal, but as with
so many combinations it packs a surprise.
I named the picture "Waking Up" because the black patches
surrounded by glowing rings remind me of the things I see when a
pleasant dream is beginning to break down and awakening is
approaching. The parameter file runs in about three minutes.
If this is too slow, the GIF image has been JPEG'd and posted
without its data to:
<alt.binaries.pictures.fractals>
from where it may be downloaded with a minimum of hassle.
The image is also available at Paul Lee's web site at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The all-unimportant fractal weather was quite pleasant today,
though shirtsleeve temperatures in the high 40'sF (9C) seemed a
bit out of place with snow still piled 2 meters deep at the
sides of the roads. The mildness did bring the fractal cats
onto the porch to enjoy a few minutes sunshine however.
Before we leave our friend Percy Smedley and his fourth
dimension, there is one more hyper-feature to be discussed --
the regular tilings of hyperspace. In two-dimensional space
there are three regular tilings. These are with equilateral
triangles six at a point, squares four at a point, and hexagons
three at a point. In three-dimensional space only one regular
tiling (perhaps better called a honeycomb) is possible. This is
with cubes eight at a point.
In four-dimensional space three regular honeycomb tilings are
once again possible. These are with 8-celled hypercubes 16 at a
point, 16-celled hexadecatopes 24 at a point, and 24-celled
icosatetratopes 8 at a point.
Just as is the case with the regular polytopes, the regular
honeycombs grow scarce in spaces of more than four dimensions.
The only regular honeycomb possible in these higher dimensions
is the 2n-celled hypercubical one, with 2^n hypercubes at a
point.
And now, before I work myself into a state of hyper activity,
it's time to shut down the fractal shoppe and call it an
evening. Until tomorrow, take care, and if I had my choice, I'd
choose space of four-dimensions to live in.

You can set your own favorite default palette by adding
the line

to your sstools.ini file (substitute your own mapname).

I think you missed the point there... Clustor is a clustering server, for
using multiple computers for any and all calculations. The fractal movie
was just an example.

Oh, I got the point all right--only after moving to other pages at the site and
reading about Clustor. But when you went to the site clicking on the URL I
provided, what was the first thing that hit your eyes boldly? It was this:
Computer Movies: Generating a Movie with Fractint.
Whoever wrote that page made it seem as if what was being advertised was an
accessory for FractInt. It did not say, "Computer Movies: Generating Fractal
Movies using Clustor 2.0."
I was drawn to the page because of the word, "Fractint," and not by the word,
"Clustor." Hence my assertion that if I wanted a FractInt movie maker, it would
be a joke for me to spend $1,995 to have one, when there are already several
good ones out there that cost very little money or are free.
Caveat emptor.

Could someone point me in the right direction. Running MAKEFCFG.EXE that

Load error : no DPMI - Get csdpmi*b.zip
I could guess that DPMI stands for Display Parameters Master Index and that
it is in the zip file. However the wild card in the file name can't be
correct and I can't get any results from a search for part of the name. No

Date: 11 Feb 2000 01:03:19 -0500 (EST)
FOTD -- February 11, 2000 (Rating 8)
Fractal enthusiasts and visionaries:
I really like today's fractal image. That's why I gave it a
rating of 8, which is much above average. The scene is part of
the fractal that results when Z is subtracted from Z^(-5) and
the difference multiplied by 1.1.
The midget in today's FOTD almost found itself, appearing almost
by magic at the end of my first random dive into the parent
fractal.
The brazen pattern around the central Minibrot reminds me of a
medallion. I therefore named the picture "Fractal Medallion".
The color palette is another fine example of serendipity. It
appeared with just two strikes of the <enter> key. I manually
adjusted only a few registers to fine tune the colors.
The parameter file is a slow one, which takes 20 minutes on a
Pentium. But salvation is at hand in the form of the JPEG file
of the image, which has been posted to Usenet at:
<alt.binaries.pictures.fractals>
and to the Web at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today was unusually mild. The warm sunshine
and temperature of 54F (12C) lured the fractal cats onto the
porch, where they spent nearly an hour enjoying the outdoors.
However, I was too busy with fractals and work to enjoy the
false spring, and spent the afternoon in front of my computers.
I'll likely do the same again tomorrow. The result can be only
another FOTD, which may not rate another [8], but will be a fine
image nevertheless.
It's also time to get a bit of excitement stirred up on the
languishing philofractal list. If I find the time in tomorrow's
FOTD, I'll take off my mask of rational thought, put on my mask
of magical thought, and post some wisdom. If I fail to find the
time for wisdom, I'll still find time for a fractal.
Until 24 hours from now, take care, and I've yet to read a
mystery novel where the fractal was the culprit.

Some predefined variables are reset to the appropriate value at the
beginning of each pixel (such as pixel, whitesq, etc.) Other variables
are given a specific value at pixel one (such as pi), or if not, the valu=
e
(0,0). These values are not reset each pixel, so going into the
initialization section of pixel 2 and thereafter, these variables will
still have the value which they had when the previous pixel was
completed. Thus it is important to use care in initializing variables in
a Fractint formula.
Using your example:
z=3D1/pixel, c=3Dc1^2+c2^2, c2=3Dpixel/z-(1.099,0)
c1=3Dconj(imag(pixel))+c2:
the second statement will have c1 and c2 equal to (0,0) at the first
pixel, but at the second pixel and thereafter c1 and c2 will carry over
their values from the previous pixel. This is not good formula writing
technique, since different drawing options (tesseral, boundary tracing,
solid guessing) will compute the pixels in different orders and therefore=
give different results.
This formula was rewritten by someone else to eliminate the problem; the
revised formula is also in _rc1.frm. In this formula each initialization
statement uses only those values which have been previously initialized i=
n
the initialization section, so the problem of carryover values is
eliminated. This is the preferred way to write formulas.

I suspected that the values of c1/c2 would carry over from the previous
pixel - thanks for confirming that. I saw the other version of 1313, and
that's when I realized the differences. However, the images created using
the two different formulas are different, are they not?

You might try going through several days worth of the FOTDs at the
following URL:
http://home.att.net/~Paul.N.Lee/FotD/FotD.html
There are links to specific key words (such as "4D") which will lead you
to further information on that topic.
Sincerely,

FOTD -- February 12, 2000 (Rating 4)
Fractal enthusiasts and visionaries:
Today's fractal is a result of adding Z^(-3) to 2Z^2 and then
adding C to 1/10 of the sum, and repeating the process until a
fractal appears. For some reason I was reminded of a thistle
plant when I saw the image. As a result I named the picture
"Thistles".
The parameter file is a three-minute one. I leave it up to the
potential viewer whether the slightly-below-average image is
worth the effort of running the file or of downloading the image
from:
<alt.binaries.pictures.fractals>
or from:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today was once again spring-like in the
middle of winter, with warm sun and a temperature of 56F (13C)
that lured the fractal cats onto the recently appeared patch of
snow-free ground at the corner of the porch.
The hastiness of the fractal and shortness of the discussion are
a result of an unexpectedly busy day, which causes me to
postpone my philosophical wisdom until tomorrow. But be
patient; when the philosophy finally appears, it will have been
worth the wait. Until tomorrow, take care and see you soon.

Subject: (fractint) If you somehow get unsubscribed ...
Date: 12 Feb 2000 11:13:17 -0600
This is a common enough question about the list that I thought I'd
post this to everyone. I really don't want to start a discussion about
list administration here (though if you have comments feel free to
email me) but occasionally this reminder is useful for list
,members, so here goes:
A list member wrote:
> I subscribed to the Fractint list last year, and for some reason, I haven't
> received any messages since January third. I resubscribed, and sent a test
> message, and have not received a reply. Did I do something wrong?
You certainly haven't done anything wrong. I moderate this list with
a very light hand, and if you had really done something wrong (very
rare), I would let you know by email. Even if you had done
something wrong (e.g. upload a binary to the list) in most cases
you'd get an "oops please don't that" email and would not be
summarily unsubscribed.
What probably happened is this. On a daily basis I see messages
bouncing from list members whose email addresses are not
working for some reason. Usually after waiting a day to see if the
problem fixes itself, I unsubscribe the list member's email address.
I don't bother to send an email explaining because most of the time
the problem is that indeed the email address is not working, so
sending an email would be futile.
The problem with this is that there can be internet problems that
cause email to bounce that aren't really due to your email not
working right. I can't always tell. So your email address could get
unsubscribed even though your email account is OK. So if a few
days go by with no list messages, try resubscribing.
Tim

Yes, because at each pixel "c" will be given a different value.

I'll keep it handy. What I would like to find is something that will
translate the fractint map into RGB values.
I would like to take something like the below segment and turn it into
hex code, but I don't understand how the color maps in PAR files are
generated. If anyone knows how to do that, or has a link, I would
appreciate it.

I understand what you're saying and remember there was discussion about that
very topic here a long time ago. I never heard from that discussion whether
anyone every took the color segment of the parameter file and converted it to
RGB values. I suspect no one hasn't. Maybe you could ask Tim whether this feat
has been accomplished or not. I suspect it hasn't.
The RGB values list I posted today will help those who have learned how to edit
FractInt's color palette within the program to punch in the numbers on the
chart for each color name they want to have in their images.

Xylen,
- I'll keep it handy. What I would like to find is something that will
- translate the fractint map into RGB values.
The encoding for this is straightforward, albeit cryptic. Each red, green,
and blue value is encoded as a value from 0-63, represented by a character
extracted from this string:
0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ_`abcdefghijklmnopqrstuvwxyz
Where colors can be linearly interpolated, they are condensed; a < means
begin interpolating, followed by a number of colors to interpolate,
followed by a >. As many maps produced by FractInt contain such linearly
interpolated segments, some space savings can be achieved by this.
Of course, \ indicates the color string should be continued on the next
line, and leading spaces do not matter.

Thank you very much. That is exactly what I was looking for. It should
be fairly simple to write a script that will convert the strings into
RGB values. I had guessed the part about the alphanumeric part, but was
unsure of the exact sequence, and the <#> part was just plain confusing.
Now I can proceed with a pet project I have been thinking about for a
year. As soon as I get it working, I'll post my results.

Subject: (fractint) FOTD, 13-02-00 (Ylem [5]) (c)
Date: 12 Feb 2000 22:41:21 -0500 (EST)
FOTD -- February 13, 2000 (Rating 5)
Fractal enthusiasts and visionaries:
I named today's fractal "Ylem", a strange name indeed. The word
looks like someone's name spelled backwards. Actually it's the
name sometimes gave to the primordial substance from which all
the elements were formed. It existed for only a tiny fraction
of a second after the "Big Bang", which, according to most astro-
physicists, started our universe going.
I got thinking of ylem when I picked up the local newspaper this
morning and saw an article stating that some physicists have
recreated ylem in the high-energy laboratory. Of course, no one
can hold a blob of ylem in their hand, or even preserve it in a
bottle, but the signs are there that for an instant, the primor-
dial ylem soup actually existed.
Today's fractal may not resemble actual ylem, but when I saw it,
I was reminded of vast energies in the realm of the sub-atomic.
It's a rather simple scene, with bubbles surrounded by chains of
satellite bubbles, while other bubbles are caught in the act of
fissioning.
The image was generated by the 12th and last in my series of
MandNewt formulas, which are variations of the Ikenaga function.
At almost 13 minutes, the parameter file is slow enough to make
a download the better choice. That download may be obtained by
going to the Usenet group:
<alt.binaries.pictures.fractals>
or to Paul Lee's web page at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
and picking up the image from there.
The fractal weather today was cloudy and cold, with one or two
flakes of snow. The temperature of 28F (-2C) was far too chilly
for the fractal cats, who hugged the nearest radiator for most
of the day.
I had honestly intended on starting a new round of fractal
philosophy in today's FOTD, but I just haven't been able to find
the on-switch. I'll try again tomorrow. Until then, take care,
and three-dimensional space isn't too bad after all.

Morgan,

you
- could use Fractint _itself_ to make the conversion via the colour map
- editor :)
Yep, this works for a couple, but if you're writing a program that you want
to parse dozens of parameters (or perhaps pre-build parameters for
animation or browsing) then you need to have the software be able to handle
it automatically. I think that's what Xylen wanted.

Oh, of course that was hardly a production solution :). I only mentioned it
as a stopgap measure to obtain _something_ to work with (and as a way to
help test scripts).
But even so, it just occurred to me that Fractint _does_ have scripting --
at least to get from colour map parsnips to RGB .map files.

Actually what I want to do is create a string of characters that have
some meaning, and then see what happens when they are turned into a
color map. I wanted the RGB values because I can use them with a
Mesa/GL program I am writing. Just think, what would a fractal look like
with the Gettesburg Address or a Shakespeare sonnet.

This is just the list of color names from Mathematica, isn't it?

I don't know. I just copied and pasted it from the URL I found it at into the

Date: 13 Feb 2000 23:42:36 -0500 (EST)
FOTD -- February 14, 2000 (Rating 6)
Fractal enthusiasts and visionaries:
Today's fractal is named "Sundial", not because it actually
resembles a sundial, but rather because I thought of a sundial
while trying to find a name for this striking image.
The parent fractal is based on the M-Mix4 formula calculating
1.055*(120Z^(120)+Z)+C, which is very near the point where the
fractal flips inside-out. The image blends the high-order
thistle features with the quadratic features of the central
midget. The midget lies in the East Valley area of a larger
midget, and that larger midget lies on the negative tail of its
parent fractal.
At over 16 minutes on a Pentium, the parameter file demands
patience. A far more convenient way to view the image is to
download it from the Usenet binary group:
<alt.binaries.pictures.fractals>
or from Paul Lee's web site at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather was cold, cloudy and raw today, with drizzle
beginning at nightfall. The temperature of 32F (0C) kept the
fractal cats hugging the radiators.
The enlightening fractal philosophy is brewing, but not yet
finished. Tomorrow may be the day it is ready. Until then,
take care, and is a fractal an animal, a vegetable or a mineral?

Well, a Fractint autokey script that will get the colour map for Foo out of
bar.par and save it as foo.map would go something like this:
"@"
F6
"bar"
ENTER
"foo"
ENTER
WAIT 0.5
"e"
ENTER
"s"
"foo"
ENTER
ESC
And this could be repeated within the .key file. Two things that may make
this slightly more than trivial are the WAIT instruction (if this is too
short, Fractint may not have time to find the formula), and the repeated
concentrated switching of video modes, if your monitor uses relay switching.

The short answer is nope...it's actually better. I'm running winders98 with a
MilleniumII graphics card. Just remember to disable all your screen savers, power
savers, life savers before you start a long fractal session under winders.

FOTD -- February 15, 2000 (Rating 5)
Fractal enthusiasts and visionaries:
When I remember the 1970's, I shake my head in wonder. Whatever
happened to the CB radio craze? I guess the cellular telephone
craze replaced it. Cellular telephones are convenient, but I
miss the CB days. Gone are the days when calls of, "What's your
10-20 good buddy?", filled the airwaves. How many today even
know what that call means?
Well, my 10-20 is fractal central, and the name of today's
fractal is "Ten-Twenty". I did not give it that name because I
wanted to know where it was located; I gave it the name because
the formula combines 5 portions of Z^10 with 15 parts of Z^20.
Unlike yesterday's "Sundial" image, today's fractal is a rather
unassuming one with subdued colors, which looks better from a
distance than from close up. It resembles nothing as much as a
lumpy spinning square surrounding a prominent central midget.
The parameter file requires 7 minutes to render. This is slow
enough to make a download of the finished image the better
choice. The image file may be found on Usenet at:
<alt.binaries.pictures.fractals>
and on the web at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today was partly cloudy and quite mild, with
a temperature of 60F (15.5C) that lured the fractal cats into
the yard for a half-hour romp in the sun. Of course, they were
careful to avoid the remaining piles of snow.
The next outburst of philosophy is about ready to go, the only
hold-up being that I have not yet thought of a way to connect it
to fractals. But fear not, the connection will come, and then
so will the philosophy. All this might even begin as soon as
tomorrow, so stay tuned with bated (not abated) breath for the
coming enlightenment.
Until tomorrow, take care, and keep watching for those signs and
wonders.

Wish I had thought of that earlier (referring to rgb.txt). I plugged "rgb.txt"
into AltaVista and it came back with 4,680 hits. The fourth on AV's "hit list"
was at
http://cvs.labs.redhat.com/lxr/source/sart/scheme-core/rgb.txt .
It had an even lengthier RGB values list than the one I sent out on the 12th,
but it didn't sort out the colors into whites, greys, blacks, red, etc., as did
the other list. So, if someone wants to find a better listing of RGB values,
just go to your favorite search engine and do a search on rgb.txt and look for
one that you will like better than was posted here.

Patch 8
Fixed a bug causing a lock up with lsystem and ifs fractal types
when using a disk video mode with an X or Y resolution greater
than 2048.
I would appreciate anyone who can verify this bug with 20.0.7 and
verify that it is fixed in 20.0.8. My understanding is that you don't
need to go much over 2048 to see the bug. To save time you could
probably make an oddball disk video mode like 2100x 210.

Subject: (fractint) FOTD, 16-02-00 (Highest Mandelbrot [7]) (c)
Date: 15 Feb 2000 22:34:26 -0500 (EST)
FOTD -- February 16, 2000 (Rating 7)
Fractal enthusiasts and visionaries:
Today's gorgeous midget with its sinuous neon-blue curves must
certainly be calculated with the M-Mix4 formula. Right? But
it's not. Today's FOTD is a scene in the classic Mandelbrot
set, which lies not even at arbitrary precision depth.
It is an unusual image however. The logmap value of 91500 and
maxiter of one-million are not mistakes. In fact, most of the
image has an iteration count well in excess of 100,000, which
makes it the highest iterated image in FOTD history and inspires
the name "Highest Mandelbrot".
The location of the never-before-seen midget is deep in Seahorse
Valley, down where the features have periods measured in the
hundreds and thousands. In this area the 'stars' at the ends of
the radical tails are twisted into triple spirals. Today's
midget lies deep in one of these star-spiral arms.
Unfortunately, I lacked the time to give this scene the coloring
it deserves, but the palette I settled on is not too bad. Being
so deep in Seahorse Valley, where the iteration count is so
high, the scene takes near 1-1/2 hours to render from the
parameter file. Therefore the image download is the way to go.
The parameter file is attached as a reference for those few who
might wish to further explore this area. The image file has
been posted to the binary newsgroup:
<alt.binaries.pictures.fractals>
and to the web at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather was an average uneventful midwinter day,
with bright sunshine, chilly breezes, and a temperature of 44F
(6.5C) that was just a bit too cold for the fractal cats.
The fractosophy is not quite ready as of post time this evening,
but I have a lot of it accumulated, some of which is certain to
be controversial. So until next time, take care, and how would
one prove scientifically to a person who never remembers their
dreams that it is possible to fly in dreams?

Tony, I thought your question would be of general interest, so I am postin=
g
the question and answer to the list.
Tony Hanmer asked:

The file
ftp://ftp.fractint.org/fradev.zip
contains just the fractint executable with changes from 20.0 made by the
developers in the first 8 post-version-20.0 patches. This replaces the
fractint.exe in the version 20.0 distribution. You should rename or otherw=
ise
save the old fractint.exe in case there is a problem with the developer ve=
rsion.
We have put all kinds of dire warnings about being on the "bleeding edge" =
in
the developer version. We just want to make sure everyone understands that=
the developer version changes very rapidly (sometimes daily) and that new
problems can be introduced. On the other hand, the developer version also
has bug fixes, so in most respects at this point is probably more stable a=
nd
reliable than version 20.0.
It is a new policy for us to make every incrementable developer version
public. There is no reason to keep up with each version unless a particula=
r
bug fix or new feature is of interest. Tony, since you want to make IFS an=
d
Lsystems fractals larger than 2048 wide or high, you need 20.0.8. Don't wa=
it
for a "release" which could be a long way off.
The bottom of this message contains the "What's New" since version 20.0.
You will see that the total amount of change is not too great yet, but som=

you may see changes that are important to you. If you want to try Sylvie
Gallet's mandel Lake PAR, for example, you will need a version that at le=

Patch 8
Fixed a bug causing a lock up with lsystem and ifs fractal types when usin=
g
a disk video mode with an X or Y resolution greater than 2048.
Patch 7
Updated Xfractint, copyright notice.
Patch 6
Fixed fractint.cfg problems with extra commas or long lines. This allows t=
he
output of makefcfg from certain video boards to be used without editing.
Added center, magxmag, and rotskew constants to parser. See
Center-Mag Predefined Variables
Patch 5
Added new command truemode=3Diter, which is used to switch the ouput to
the truecolor Targa file to the number of iterates for each pixel.
Made selecting the evolver feature turn off truecolor=3Dyes. Each subimag=
e
was being generated as a separate blank Targa file.
Patch 4
Fixed the type=3Dtest bug.
Removed Tim's compuserve email address.
Patch 3
Fixed a bug in the pentium mandelbrot code that affected periodicity
checking. Fixed a problem with skewed zoom boxes leaving dots on the
screen. This also fixed browser boxes with the same problem. Fixed the
zoom box so it is visible in 2-color modes.
Patch 2
Fixed a bug in the formula parser. Updated Tim Wegner's email address.
Patch 1
Fixed the 2 and 16 color disk-video modes. Using truecolor=3Dyes now resu=
lts
in writing a fractxxx.tga file instead of iterates.tga. This is not the s=

Date: 17 Feb 2000 00:40:19 -0500 (EST)
FOTD -- February 17, 2000 (Rating 4)
Fractal enthusiasts and visionaries:
After staring at today's fractal for a few minutes, trying to
find a name, I got the feeling that I was being drawn into it,
about to begin an endless journey. I immediately named the
picture "Fractal Journey".
The formula is once again the warhorse MandelbrotMix4, this time
calculating 1.6*(0.3Z^(-3)+3Z^(0.3))+C. The fractal that
results from this unlikely combination is hardly more than a
broken outline of dots, which in a few places form the vague
shape of a Mandeloid section. I have learned that when this
outline effect appears, the complete figure often lies like an
invisible phantom in the blank area of inside points, and can be
revealed by setting the inside coloring option to a non-flat
palette, such as the bof60 used in today's image.
The parameter file takes 12 minutes on a Pentium -- slow enough
to make a download of the image worth the small effort. That
image is available on Usenet at:
<alt.binaries.pictures.fractals>
The image is also to be found on the Web at Paul Lee's web site:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today made the cats very happy. The bright
sunshine and temperature of 68F (20C) were perfect for romping
in the yard, though there was a moment's distraction when a
stray tomcat on an important mission passed by.
And now I have some good news and some bad news. The good news
is that I'll return in 24 hours with much to say; the bad news
is that we've come to the end of today's FOTD. Until tomorrow,
take care, and brace yourselves for what is coming.

It's interesting for all of us. Fractint is an ongoing, ever-improving
volunteer project. No one gets paid for developing it.
If you don't want to discover 'new bugs', stay with the tried-and-true
versions. You'll be just as happy.<S>

Hi,
I am using the X11 version of fractint that I just picked up today.
The display that I'm on is at 16 bits per pixel and the fractals (mandelbrot set so far)
I get out of fractint are all in just one color (red)
How do I get to generate fractals in more colors?
Thanks!

Hi there,
Some time ago I downloaded GIF files created by fractint,
and loaded them into fractint and explored a bit from there.
Now, of course, most fractint pics are in PNG format...
Fractint won't let me load them, and converting them to a gif doesn't help
either.
I note that the fractint page says that all their files will be in PNG
format in future, but the program still only saves and loads GIF
(as far as I can tell... PNG does not seem to appear in the docco)
Is there any way to get fractint to load PNG? Or to convert a PNG
to a fractint-compatible gif? Or to extract the parameters from the PNG?
Thanks!

As far as the "still bleeding" part, I have to confess that I'm
responsible for that metaphor, but it is really a pretty big
exaggeration <g!> As far as 20.0.8 is concerned, it has a number
of bugs fixed, so it "bleeds" less than version 20.0. When we add
major new features the situation will be a bit different.

That is exactly the idea. We changed our policy precisely because
we think more rapid interaction between users and developers as
changes are made and users give feedback will be helpful for
everyone concerned.

FOTD -- February 18, 2000 (Rating 6)
Fractal enthusiasts and visionaries:
Though I'm always telling of the activities, or rather the lack
of activities of the fractal cats, I never expected to see one
of them appear in a fractal. But as all fractalisis know,
fractals always do the unexpected. Today's fractal is only a
single example of the unexpected.
Directly in the center of the pop-art stlye image, near the top,
appears the outline of the head of Tippy, the lean mean fractal
tabby. There are also other cat-like features all through the
image, from the staring eyes to the cheshire grin. I named the
picture "Fractal Cat" when I noticed the cat's head in the image.
The formula that drew Tippy is one I rarely use, named Mystic2.
With the inside set to a flat color, this formula draws
virtually nothing but empty circles, but with one of the fancy
inside= options, the variety of fractal patterns within the
circle is unlimited.
Today's image consists solely of bof61 inside fil. This can be
demonstrated by setting the inside to 0 and observing the black
screen that results. Curiously enough, bof61 appears to be the
only inside fill that works with this particular image.
The parameter file runs in 3-1/2 minutes on a modest Pentium,
faster on a faster machine. The JPEG-format image file is
posted to:
<alt.binaries.pictures.fractals>
and to:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
for convenient retrieval.
Though the day was sunny, the temperature of 36F (2C) was too
cold for the fractal cats' ears. They decided to spend the day
chasing sunbeams and seeking the warmest radiator when the
sunbeams failed.
That's it for this evening. Until tomorrow, take care, and be
an optimist who sees the doughnut, not a pessimist who sees the
hole.

Steve asked:

No, no, and no. Wish I had a better answer <g!> Once a fractint
GIF is converted to PNG the parameters are gone. The best you
can do is save them to a PAR file before converting to PNG.
Yours truly is one other original authors (albeit a minor one) of the
PNG spec. I have even reserved a PNG chunk name for fractal
parameters (fRAc). I am commited to ditching GIF in favor of PNG.
I don't necessarily speak for all of The Stone Soup team, but I
haven't heard any opposition to the goal of replacing GIF with PNG
either.
The problem is that Fractint uses an obsolete development
platform, and is tied to the DOS medium memory model, in which
data segments can be no larger than 64K, and there is still a 640K
limit of conventional memory. I was able to get fractint to link with
the the Libpng, but it would run because of PNG memory
requirements. I can see ways to make PNG work with Fractint but
they are ugly, and the time is better spent moving Fractint into a
future development platform than shoe-horning a feature that
doesn't fit onto the old legacy platform version.
PNG support is a complete non-issue under Window 9X or Linux,
or even under DOS with the djgpp compiler. The reason it has
taken this long and PNG is still not integrated is mostly that your
humble team is mostly made up of older folks with older skills, and
the code too is "old" and has gotten very complex. It's a catch 22
because we don't attract new programmers with fractint on an old
development environment. There was a time when fractint's SVGA
graphics and integer math were state of the art, and young
programmers were interested in contributing.
This may sound like I'm discouraged, but I'm not. I am personally
on a binge of learning new things. I am even a card carrying
student right now (taking a graduate level course on Kalman filters).
We are rehosting our team from CompuServe to fractint.org, and
working on ramping up our Linux skills. I am personally researching
platforms and techniques for a new platform.
Fractint's transformation will take some time because the main
work will probably have to be done initially by members of the
current team. However, I expect that once we have workable
versions out from under the medium memory model, there will be
an acceleration of growth and a new team. I don't expect Fractint to
ever again dominate the fractal scene the way it has for most of the
last decade (nor do I mind that it won't) but I do expect it to have a
new life and to continue to change and grow.
The new Fractint will run the same (or nearly the same) under
Linux, Windows, the Mac, BEOS, and maybe even under DOS.
Fractint will be officially open source using one of the current open
source licenses. (Believe it or not despite being a pioneer of a
program with published source, Fractint is technically not "open
source" under the current definitions because our license doesn't
allow you to take our source and use it for your own commercial
fractal program.) There will be no more integer math. PNG will be
the main graphics format. Parameters will be stored inside the
PNG in a largely application-independent way. Fractint will support
truecolor via both super palettes and a formula-like procedures
based on something like the parser. The built-in types will be gone;
everything will use formulas. 2D, 3D and 4D fractal types will be
supported with some compatibility to POV-Ray for 3D and 4D.
My crystal ball may not be 100% accurate, but that's the way it
looks to me. There are probably a whole lot of new things I haven't
mentioned, like built in support for distributed processing across
the internet. I mostly listed ideas I've had for a while - we're not
limited to those ideas.
Don't ask me how soon all this will be done. :-) It won't be in the
next few months, but neither will it be years away. There is more
movement toward this future now than there has been for the last
few years.

Hmmmm... What language is it written in?
I'd have thought that maybe going over to gcc (which is available for both
windows/dos and unix...) might be a good plan?
It would certainly remove the memory model constraints... I guess...

Both of these questions are related. Yes, PNG and truecolour support is
expected (nay, demanded) in a future release of Fractint; it's not here
yet, though. The 16bpp video mode is really there for the developers'
benefit, and doesn't serve much of a function yet.
Fractint is still a 256-colour GIF generator with no idea what to do with
PNG, sorry. But stay tuned...

Sooo... apart from starting my X server in 8 bpp and apart from using 'disk video'
there is no way I can use xfractint in X windows to generate fractals in 256 colors?

Has there been any discussion on what sort of architecture a future
Fractint might have? I've been kicking a few ideas around myself and would
like to know what others are thinking, in case they've thought similar
ideas through in less ignorant detail.

This is nice to hear. And the occasion to thank you and the fractint
developers for hundreds (if not thousands) of hours of fun and amazement
I've had with fractint.

There has been tons of discussion and even some work from yours truly
before my free time evaporated ;-).
The best thing to do if you're thinking of contributing is to join the
fractint developer's mailing list: send mail to majordomo@xmission.com
with 'subscribe fractdev' in the message body. You can also peruse
the archives of what's been said before on that list at
<ftp://ftp.xmission.com/pub/lists/fractdev/>.
I'd like to humbly suggest that all development threads continue on
the fractdev list and not the fractint list, so as to not bore users
with long threads full of programming details.
I can summarize what's transpired before:
1) fractint needs a 'driver model' in its source code to isolate the
main body of code from things that are platform specific. 'Platform'
here refers to a combination of compiler support, operating system
support, keyboard/mouse input support and of course screen output.
2) Designing this support for fractint's existing code base requires
someone who has a 'high level' view of the code so as to make sure
that nothing major is missing in the design.
3) fractint has a LARGE code base. Printing out the source code in
a double-sided listing results in a stack that is literally 6 inches
thick. Getting the 'high level' view is time consuming!
4) The 'driver model' should be introduced into the code in such a
fashion that it doesn't require an entire rewrite.
5) Modern platform environments are event-driven (X11, Win32, MacOS,
BeOS), and don't use a polling I/O model like DOS. Fractint currently
uses a polling I/O mechanism but xfractint snuck in a way to treat
this through events. It has some warts, but it does work. The better
long term solution is to reorganize the code into an event-driven
paradigm, but that can wait until after item 4.
I've done 1-3 and part of 4. Once I got the 'big picture', the job
wasn't as hard as I thought it would be at first. I think my approach
will unify ports to X11, Win32 and MacOS. DOS may still work, but it
is a low priority for me ;-).
However, while doing item 4 I ran out of spare cycles to work on
fractint. I have a code base that is partially completed and still
compiles/limps along on X11, but it needs more work.

Subject: (fractint) FOTD, 19-02-00 (FMOD Test Number One [3]) (c)
Date: 19 Feb 2000 00:32:24 -0500 (EST)
FOTD -- February 19, 2000 (Rating 3)
Fractal enthusiasts and visionaries:
Today's FOTD features the little phantom midget that isn't
there. It isn't there, that is, if the scene is calculated in
the standard manner, with the inside set to 0 and the outside
set to iter. Nothing appears in today's image but trapped
inside points, yet even though they are trapped, these points do
different things in their confinement -- things that when
brought out by an inside=fmod fill, could almost be mistaken for
a real midget and its surrounding 2,4,8...pattern. I could rate
it no higher than a three, because it is only a test.
I have named the picture "FMOD Test Number One" because today,
following a suggestion from Iain Stirling, I began experimenting
with the fmod inside fill and discovered that it has great
potential when applied to these phantom midgets. I'll be
posting a lot of these non-existent midgets in the weeks ahead.
They're easy to find with the M-Mix4 formula, and will produce
some unique images with the various inside fill options
available.
The parameter file of today's image is a rather slow one, all
the more reason to download the image file from:
<alt.binaries.pictures.fractals>
or from:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today was interesting. The day started with
snow, which accumulated about 2 inches (5cm) before changing to
ice pellets, then to freezing rain, and finally to just plain
old rain. The rain was followed by dense fog in the evening and
a threat of thunder-storms. The fractal cats took one sniff of
the outside air this afternoon and turned back into the kitchen.
They got into a little spat a few minutes later, probably
because of their anger over being unable to go outdoors. But
they soon made up and all is now well.
All is also well here in Fractal Central, except for the problem
that it's time to shut the place down. The philofractal version
of today's FOTD will appear in about 12 hours, when I have a
chance to compose the philosophy. Until tomorrow, take care,
and make friends with a fractal.

Jim,
I am very taken by this FOTD. The colouring is magic - I find that
getting good contrast on the bubbles without the colours looking garish
is very difficult, but your FOTD today shows that a balance can be
found.
I eagerly await further inside=fmod offerings...
Iain Stirling.

Having decided recently to re-discover Linux, and try to learn a
little about it, I installed RedHat 5.2 in an *old* machine. With
surprisingly little trouble, considering the depths of my ignorance
of this platform, Xwindow was up and running. I then decided to
install Xfractint, which was *not* quite as easy, as this 486-25 SX
box had no connectivity to the rest of the world. I used the
package assembled by Scott Boyd and available at Spanky. This was
downloaded to my WIN95 machine and transferred to the Linux box via
a floppy. After considerable hair-pulling, Xfractint came to life,
in a manner of speaking. I clocked the demo Mandel at just over an
hour for a 640 by 480 display! Still, I think this says a lot for
the basic Fractint code, which survived porting to a foreign OS, and
operated quite well with a chip sans a math co-processor!

This is cool! I have plans to build a parallel computer out of dozens of
such machines... each one will work on one 'pixel' at a time...
and when its decided whether that 'pixel' is in the set it returns its result
to the root node, and gets assigned another 'pixel'.
This way all the machines are operating at full capacity 100% of the time...
:-)
one day... ONE DAY!

Date: 19 Feb 2000 22:49:37 -0500 (EST)
FOTD -- February 20, 2000 (Rating 4)
Fractal enthusiasts and visionaries:
Today's FOTD is a zoom into yesterday's image, with a slightly
different color palette applied. As was yesterday's scene, the
entire scene is phantom, being made visible only by the use of
inside=fmod fill.
I'm still in the very early stages of discovering the things
this fill can do, but one thing I already know for sure is that,
as today's image shows, it can produce very 3-D looking images
in areas where nothing was thought to exist. I'll post FOTD
examples of my discoveries as I discover them.
Today's picture impresses me as an image of well-weathered
rocks. Or it could be a picture of a flower made of stone -- a
petrified flower. I named the picture "Petrified Flower"
accordingly. It's a more poetic title than "Weathered Rocks".
The color palette is the built-in Fractint S-F1, with only a few
minor adjustments to give the sepia tone of a faded photograph
and a slight blueish tint to the highlights.
Consisting solely of trapped points, the image is unusually slow
to render from the attached parameter file. A far better choice
is to download the image file from either:
<alt.binaries.pictures.fractals>
or from:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather was far more reasonable today, with
occasional sunny breaks and a temperature of 50F (10C) that was
just mild enough for the fractal cats to venture onto the porch
for a half hour or so. That short outing must have worked,
since they got into no squabbles the rest of the day.
Unfortunately, I have no further philosophy at this time. The
reason is not that I have nothing to say, but rather that I
exhausted my philosophical energy earlier today, writing
yesterday's philofractal version of the FOTD. For some reason,
writing about metaphysical philosophy drains my energy faster
than any other topic. I guess I'll need a few day's break
between outbursts of wisdom.
And now it's time to shutter the fractal shoppe and call it a
night. It's Saturday evening -- the evening I reserve for doing
nothing but watching old sci-fi movies. (They're not good
enough to be called films.) If I fall asleep in the middle, so
much the better.
Until next time, take care, and if you discovered the secret of
the universe, would you keep the secret?

Subject: (fractint) Just a FEW more L-systems... 1/6
Date: 20 Feb 2000 10:36:02 GET
It┤s amazing how living in a place where the electricity exists for about 6
hours a day, and where one doesn┤t have instant computer access, can be
conducive to "thought experiments".
The sets of l-systems (adh119-123) which I am sending separately are all
derived from only one original formula, upon which I stumbled on Feb. 13,
and then thought about extensively when the power was off. I varied the
angles from the original 4 (90 degrees) to 3, 5, 6 and 8, and played with
the formula each time until the results were satisfactory, and deleted the
failures. Most of the pieces have n-fold or n/2-fold rotational symmetry (n
being the Angle), but a number of them also change this symmetry from order
to order.
I certainly wouldn┤t say that I have mastered l-systems yet - I┤m still
playing, and rarely can I actually produce a formula which does what I WANT.
The alternative - spewing out experiments and deleting the unsuccessful
ones - is enough for now.
Each of the following sets of l-systems (including the one below, a
miscellaneous collection, to be called Hanmer03.l) should be saved in a
text editor as a text file named *.l (the * being names adh119, 120, 121,
122, 123). Then Fractint can read them.
Enjoy - simpler than other formula types but capable of surprising richness
nonetheless.

FOTD -- February 21, 2000 (Rating 7)
Fractal enthusiasts and visionaries:
Today's spectacular fractal features another midget that isn't
there. Nothing appears in the image but bof61 inside fill. A
real midget originally was at the location, but when I raised
the bailout to the ridiculous value of 10^150 all the real
fractal material evaporated, leaving only a ghostly remnant of
the midget lurking invisibly in the solid sea of trapped points.
But sometimes, given just the right conditions, ghosts can be
made visible. The ghost revealer in today's case is the
inside=bof61 option, which colors the inside according to which
iteration comes the closest to the origin. When this is done,
we see a delicate, lacy filigree with the ghost of the now
deceased midget once again visible in the center. I have named
the picture "Eroded Minibrot" because of the disintegrating
appearance of the entire scene. The rating of 7 is largely due
to the extra time I devoted to adjusting the palette of colors.
The formula behind the image is Z^(0.75)+Z^(-24)+C. The
negative-24 exponent is the reason that the fractal is so
sensitive to bailout changes. When negative exponents are part
of the generating formula, the resulting fractal is always
sensitive to bailout changes. The greater the bailout value,
the more broken and fragmentary the fractal becomes, until
finally at a value such as today's, the dot-like fragments
shrink and vanish completely.
With a formula such as Z^(-4)+C this is of little consequence,
since the fractals created by such formulae hold no midgets.
But when two negative exponents are added together, or a
negative and positive exponent are added, and Z is initialized
to a critical point of the formula, the resulting fractal is
filled with quadratic midgets. These are the formulae that
produce the ghost midgets when the bailout is increased.
Producing a ghost midget is simple -- merely find a midget and
increase the bailout until the midget vanishes. Don't be
frightened off by the blank screen. The ghost of the midget
will still be there, and can be revealed by an active inside
fill such as bof60, bof61, or fmod.
In the case of today's midget, all three of these inside-fill
options draw interesting images. The bof60 version is a
scattering of tinted circles. The fmod version, which is almost
as good as the bof61 version, gives a 3-D space filled with
spheres, which can be varied in size by adjusting the proximity
value.
The parameter file of today's FOTD requires 7+ minutes to render
on a modest Pentium. This is not too bad, though the JPEG file
of the finished image may be downloaded from:
<alt.binaries.pictures.fractals>
or from:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
in less than half the time.
The day's weather, (fractal weather that is), was uneventful,
with mostly sun, but a few clouds, and a temperature in the mid
40's (around 7C) that was a bit chilly for the cats (fractal
cats that is), but not chilly enough to keep them indoors.
Well, looking at the wall clock, I see it's well past the time
to give the fractal cats their evening meal and shut both the
fractal shoppe and my mouth for another day. Until next time,
take care, and rest easy.

Subject: (fractint) anti aliasing
Date: 20 Feb 2000 23:39:55 -0300
Hi, everybody!
After you finish an image, you want to post it to some site on the web,
right?? How do you treat your fractint images?
I┤m using paintshop pro 5.01, and ultra-fractal. I save the parameters, open
them in Ultra-f and render them to disk, the size I want to use in my site
(640x480). I use the png format I don┤t know exactly why. I open it in PSP,
and save as jpg. Now, can I open the gif image in PSP and do the
antialiasing there? I haven┤t found out how with psp┤s documentation, I
guess they use another name for it. What settings do you use when
compressing with jpg?? I understand that depends on the image, but is there
a general rule? What is an acceptable size for the pictures? I have a
thumbnail page, you click on the thumbnail, you get a page with the bigger
iamge. I┤m talking all the time about this picture. I imagine that if the
visitor has clicked on the thumbnail, he/she/it also is willing to wait a
little longer for the image to appear, so I don┤t tend to make the picture
too small. I usually got pictures about 50-70k big. Is that ok? May I let
them be even bigger and therefore better?
So, that┤s a lot of questions for today, and I hope you can help me out.
Tanks,

Fernando,
- Now, can I open the gif image in PSP and do the antialiasing
- there?
Yes. Render larger than you need--at least 2x, so if you need a 640x480
image, render at 1280x960 or larger. Open the image in PSP. Convert it to a
24-bit image. Resize to 640x480. If the result is too soft, apply a slight
(slight!) sharpen effect. Save as a JPEG. All the FractInt images in my
galleries were done with this technique (although not with PSP).
- What settings do you use when compressing with jpg??
You'll have to experiment to see which ones work best. Generally, use as
much compression as you can that doesn't mangle the image. Once you find
the "sweet spot" you won't have to move too far to one side or the other
when saving your pictures; most fractals will use about the same settings.
- What is an acceptable size for the pictures?
For a 640x480 image, somewhere between 50K and 150K seems reasonable. A few
very "busy" images will need to be larger than that to prevent JPEG from
mushing them up.

Subject: (fractint) FOTD, 22-02-00 (Midget With Cherries [6]) (c)
Date: 21 Feb 2000 22:59:17 -0500 (EST)
FOTD -- February 22, 2000 (Rating 6)
Fractal enthusiasts and visionaries:
It is sometimes said that life is a bowl of cherries. I don't
know about life being a bowl of cherries, but today's fractal
midget certainly is in a bowl of cherries. At least 16 cherries
surround the midget, and the smaller eight cherries still have
their cherry-stems attached. It's no surprise that I named the
picture "Midget With Cherries".
The formula behind the cherry bowl is 1.15*(-(Z)-(1/Z))+1/C,
another unlikely candidate for a respectable fractal. One would
never think that combining Z and 1/Z could create a worthwhile
fractal, but sometimes in the world of fractals the simplest
formulas create the most complex images.
This midget is surprisingly healthy. I tried to kill it by
raising the bailout value, so I could examine its ghost with
various inside fills, but it refused to die, even with the
bailout set to an apocalyptic 10^250. It does change its colors
however at such an extreme bailout value. It also takes about
seven times as long to render, and the logmap must be reset from
283 to 2308. I have attached both the bailout=200 and the
bailout=10^250 parameter files, though only the image with the
bailout of 200 has been posted to the usual sites.
At 15 minutes and 104 minutes, the parameter files try one's
patience. To avoid impatience, I recommend downloading the
image with the bailout of 200 from:
<alt.binaries.pictures.fractals>
or from:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
If you wish to see the image with the bailout of 10^250, you'll
need to run the second parameter file, and be extra patient.
The difference is striking.
The fractal weather, (Is there any other kind?), was boringly
average today here at Fractal central, with partly cloudy skies
and a temperature of 48F (9C) that was just warm enough to
enable the fractal cats to enjoy an hour or so outdoors in the
yard.
I hate to disappoint the fractosophy fans, but the fractal
philosophy never got off the ground today. There was simply too
much paying work and too many problems for my philosophical mood
to reach full stride. But I've got much to say, and I'll be
saying it in my typical outspoken manner in the not-too-distant
future.
For now, it's time to close the fractal shoppe, feed the cats
and call it a night. Until next time, take care, and remember
that patience is rewarded.

Date: 22 Feb 2000 21:26:57 -0500 (EST)
FOTD -- February 23, 2000 (Rating 4)
Fractal enthusiasts and visionaries:
Today's fractal is a quickie that deserves no more than it's
rating of four. The image is all red and green color. There is
nothing new in the underlying forms, which have appeared in
several previous FOTD's. The formula behind the image subtracts
Z^(-3) from 1/10 part of Z^3 before adding C. I could rate this
effort only a 4, because I put very little work into it. Most
of my spare time today was spent searching for and formatting
the little philosophical story I wrote a few years back, which
will be posted to the philofractal list in a couple hours.
After a moment's thought, I named today's FOTD "Old Red-eye".
The midget at the center does give somewhat of an impression of
a staring eye, and the surroundings certainly are red enough to
warrant the title.
The parameter file is fast enough to make running it a bit less
work than going for the download. But for those who would
rather download the JPEG file of the image, it can be found
posted to:
<alt.binaries.pictures.fractals>
and also to:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today was a non-event. Warm sun and a
temperature of 56F (13C) kept the fractal cats happy.
Though the philosophy is cooking nicely, it is not quite ready.
But the little story I will post shortly to the philofractal
list will more than make up for the delay.
Now I see it's time to shut down the fractal shoppe and call it
a night. Until tomorrow, take care, and whatever happened to
the Murphy who wrote Murphy's law?

Subject: (fractint) Xfractint 3.11 binary available
Date: 22 Feb 2000 00:26:53 -0600
To all Linux/fractint fans out there:
A binary package of Xfractint 3.11, based on fractint 20.0.7 is now avaible at:
http://www.fastlane.net/~sdboyd/xfractint.html .
(The link to download the .tar.gz file is available on that page.)
This binary was compiled and is running great on Linux-Mandrake 6.1, kernel
2.2.13, xfree86 3.3.5 and KDE 1.1.2. (That setup is running on an AMD K6-2 -
450Mhz box.) It should run OK on most any 2.2.x kernel, and GNOME or KDE 1.1.x.
Will it run on older kernels and older distributions? Install it and find out,
let me know...

Damien,
Your answer is a little confusing. I use PSP4 and there are 2 options to
change the size of the image. If you resize, you suppress only unused pixels
and the result is very bad. To antialias you must choose Resample (I think
it is the word used in the English version, because I use the French one).
Indeed this option can only be selected if the image uses 24 bits for colors
(if not -i.e. GIF images- go to the bottom of the menu Colors). I think that
things are not too different in PSP 5.

Jean-Pierre,

- antialias you must choose Resample (I think it is the word used

Then shame on PSP for setting things up this way (in my opinion). There is
so seldom any reason to "resize" without resampling that to present such an
option when a better one is available is, I think, very confusing to the
user. Other graphics apps don't generally do this.
So, your point is well taken: in PSP, this option is called "Resample", not
"Resize".

Date: 24 Feb 2000 01:28:01 -0500 (EST)
FOTD -- February 24, 2000 (Rating 6)
Fractal enthusiasts and visionaries:
I was distracted from my normal fractal pursuits today by the
discovery of a web page which features images of the three-
dimensional slices of the 600-celled four-dimensional polytope
known as the hexacosioitope. I can't say that after viewing the
slices I'm any closer to visualizing the entire 4-D monstrosity,
but the slices are fascinating indeed. For any who might be
interested, the URL of the page is:
http://www.graphics.cornell.edu/~gordon/peek/600slice/index.html
I was told of the page by Andrew Coppin.
Today's FOTD is one of the most unusual scenes I have yet found
by using nothing more than the everyday equal-iteration bands.
It is a scene in the fractal that results when Z^0.78 is
subtracted from Z^0.5 before adding C.
I named the picture "Fire Midget" in recognition of its
liveliness rather than as an attempt to describe the scene. It
is an unusually easy fractal to color, working wonders with
almost any color scheme. I could easily have chosen any of a
dozen alternate color palettes and still had a respectable image.
While searching through the parent fractal for today's image, I
found several more interesting scenes. I may post some of these
as FOTD's in the near future. The 4-1/2 minutes it takes to run
the parameter file is just long enough to make a download of the
image file the better choice.
That image may be found in JPEG format ready for downloading on
Usenet at:
<alt.binaries.pictures.fractals>
and on the Web at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today once again turned out boringly
average. The temperature was 56F (13C), but the lack of
sunshine kept the cats indoors.
The latest eruption of fractal philosophy has not yet matured,
but I've still got it cooking. Keep posted for the big event in
the near future, maybe even tomorrow. Until then, take care and
when the world gets you down, restore hope with a fractal.

Date: 24 Feb 2000 21:44:09 -0500 (EST)
FOTD -- February 25, 2000 (Rating 9)
Fractal enthusiasts and visionaries:
Today's fractal, with its rating of 9, is the highest rated FOTD
image since I began rating images about one month ago. It earns
that superior rating because of its extraordinarily realistic
representation of an actual 3-D scene in the world of fractals,
wherever that may be. The formula is a slight variation on the
formula of yesterday's image. This time Z^0.65 is subtracted
from Z^0.55 and the difference multiplied by a factor of 9.
Though most of the image was a matter of luck, I did spend a bit
more time than usual fine-tuning the color palette. I named the
picture "Jungle of Fractals". The name is well-earned,
considering the jungle of lush tropical growth surrounding the
central midget, which glows with a bronze aura.
At a running time of over 17 minutes on a modest Pentium 200mhz,
the parameter file demands a bit of patience. For the
impatient, the JPEG'd image file has been posted to the binary
Usenet newsgroup:
<alt.binaries.pictures.fractals>
and to Paul Lee's web page at the URL:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today was spring like -- warm enough in fact
for the fractal cats to spend several hours sitting in the sun
on the porch, which faces SSW. The temperature of 68F (20C)
kept them stretched out most of the afternoon. Unfortunately,
the sun finally went down, and the cats came indoors, where they
assumed their customary positions for the rest of the day.
For today, that's it, but we'll have more tomorrow. Until then,
take care, and when fractals call, heed the call.

FOTD -- February 26, 2000 (Rating 6)
Fractal enthusiasts and visionaries:
This afternoon I began thinking. (Now that's a novelty in
itself.) The topic of my musings was the fourth dimension, (No,
I'm not an egg-head.) and in particular the hypersolid figures
of 4-D space known as polytopes, whose boundaries are 3-D solids.
In 3-D space there are semi-regular polyhedrons whose faces
consist of two or more different regular 2-D polygons. The
truncated icosahedron or soccer-ball figure, a semi-regular
polyhedron which consists of 20 hexagons and 12 pentagons, is
one of these. This afternoon, I wondered how many semi-regular
4-D polytopes are possible, whose cells consist of two or more
varieties of the five regular polyhedrons.
It is immediately apparent that cubes and dodecahedrons cannot
function as cells of a semi-regular 4-D polytope, since these
are the only regular 3-D polyhedrons with squares and pentagons
as faces, and as part of a 4-D polytope, in which the cells are
joined at their faces, there would be nothing to join them with.
This leaves us with four possible combinations of the three
polyhedrons with equilateral triangles as faces: tetrahedron-
octahedron, tetrahedron-icosahedron, octahedron-icosahedron, and
tetrahedron-octahedron-icosahedron. Semi-regular 4-D polytopes
might be possible with any of these four combinations of
polyhedrons comprising its cells.
I was just starting to figure the number of possible
configurations of these four combinations, when the phone rang
and my reverie ended. But although I never did solve the
problem I had invented, I did later find a fractal.
Today's fractal is another in my series of plant-like images.
It reminds me of a scene in an imaginary fractal forest, with
lush, exotic alien plants springing into the air, while in the
background the Minibrots dive for cover.
Since the parameter file takes a somewhat unreasonable 13
minutes to render, it would be more reasonable to download the
JPEG'd image file from:
<alt.binaries.pictures.fractals>
or from:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today was a foretaste of Spring, complete
with a temperature of 79F (26C) and the obligatory late-
afternoon thunder-shower. The fractal cats took full advantage
of the warmth, spending nearly all afternoon lying on the porch,
absorbing the sun.
The fractosophy, however, made little progress today. I'll work
at it again tomorrow. Until then, take care and be good, but
not so good that it stops being fun.

Dear fractal friends,
I have the following problem:
When I want to generate a picture with video mode,
the video mode obviously ignores my setting floatingpoint=3Dno,
and uses floatingpoint calculation for the image.
Is this a known bug and how can I avoid it?
Please send any answers to my email address.
Thanks for any advice on this,

FOTD -- February 27, 2000
Fractal enthusiasts and visionaries:
Today's fractal has no midget. This is because there are no
midgets in the Mandeloid fractals formed by exponents of Z
between zero and one. In fact, there are almost no fractals in
this range. Z^0.7 gives an empty circle; (-Z)^0.7 adds a few
flat bands inside the circle. It is only when Z^0.7 and
(-Z)^0.7 are added together that an adequate fractal appears.
No midgets exist in the entire parent fractal of today's FOTD.
The number of lobes on a Mandeloid midget is one less than the
exponent of Z in the generating formula. Z^3 produces a
Mandeloid with 2 lobes, while Z^2 gives one lobe. Following
this sequence, an exponent of 0.7, such as in today's formula,
should produce midgets with -0.3 lobes. Since such midgets are
impossible, no midgets are in these fractals.
But midget or not, today's picture is an interesting one,
displaying as it does just one of the infinite patterns possible
in the world of fractals. After studying the picture for
several minutes, I got the impression that I was looking at an
emulsion of order and chaos. I therefore named the picture
"Emulsion".
I could just as easily have named it something like "Amoebae" or
"Ice Floes", but the first name that comes to mind is usually
the one I stick with.
At over 4 minutes, the parameter file is just slow enough to
make a download the better choice. That download may be found
at:
<alt.binaries.pictures.fractals>
and at:

The fractal weather today was the antithesis of yesterday's
glorious day, as a mass of cold, damp air came in off the North
Atlantic, and with its low clouds and mist, drove away the
sunshine. The temperature of 45F (7C) was just too chilly for
the fractal cats, who still remember the day in the sun they
enjoyed yesterday.
With the fractal cats worrying me for their late snack, it's
time to shutter the fractal shoppe and call it a night. Until
next time, take care, and perhaps a fractal is as close to the
spiritual as one can reach through the senses alone.

FOTD -- February 28, 2000 (Rating 5)
Fractal enthusiasts and visionaries:
When I saw today's FOTD, I was astounded, for there in front of
me were eight hairpins arranged in a perfect circle around the
quadratic Mandelbrot midget at the center. I had no trouble
deciding on a name for the picture. For purely descriptive
reasons, I named it "Eight Hairpins". It's a rather somber
scene, with a puce, (What color is that?), background framing
the central midget and its eight hairpins. The formula behind
the image combines Z^(-9999) with Z^2 before adding 1/C.
The midgets in the fractal that this formula creates are
unusually hard to find. I had searched for nearly an hour, and
was on the verge of giving up, when I stumbled upon the
combination of parameters that resulted in a fractal with
midgets.
Actually, I found an even more interesting midget earlier in my
exploration, but the midget proved to be beyond the limit of
resolution. We really need someone to build arbitrary precision
math capability into type=formula fractals. And yes, I realize
that this is easier said than done.
Requiring only two minutes to run, the parameter file is
probably the better way of viewing the image. For those who
prefer their fractals precooked, the image file is availably on
Usenet at:
<alt.binaries.pictures.fractals>
and on the web at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today was changeable. The day started
foggy, then broke into warm sunshine in the early afternoon.
But the enjoyable conditions were ended at nightfall by a heavy
thunder-shower. The temperature of 61F (16C) was just right for
the fractal cats, who spent the afternoon on the porch.
The fractosophy of the day appears in a separate letter posted
to the philofractal list. More will likely appear tomorrow.
Until then, take care and have a fractally good time.

FOTD -- February 29, 2000 (Rating 4)
Fractal enthusiasts and visionaries:
Today is leap day in a double-zero year, an event that occurs
but once every 400 years. In recognition of the momentous
event, I have produced a fractal. It's another in my
interminable series of midgets created by the MandelbrotMix4
formula.
I've named the picture "Shredded Minibrot" for no particular
reason. The expression being calculated is (1/Z)-(Z^1.04)+C, a
combination that at first glance appears to offer little hope,
but when iterated exceeds itself in the variety of detail it
creates.
The parameter file runs in 6 minutes. The download of the image
file takes far less time -- only a minute or two. That image
can be found at:
<alt.binaries.pictures.fractals>
and at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today was very average, though the
temperature of 55F (13C) was a bit above average. A brisk wind
kept the fractal cats holed up inside.
I was too busy today to get much accomplished in the way of
philosophy. But tomorrow is another day, and hopefully I'll
find more time than I did today. Until then, take care, and
never rush a fractal.

I have been getting into fractals and fractal shapes and have been leaning
that artists were influenced by and had used fractals shapes in their art
work even before the word fractals was coined. Do any of you have ideas as
to which artists these might be (like Escher maybe), ancient Indian artists,
etc.

Your assumption is confirmed. Those blocky, square and rectangular
shapes you run into at very large magnitudes are not a bug. They
are a sign that the limit of mathematical precision has been
exceeded. Since I have relatively little experience with Ultra-
Fractal, I cannot confirm that it has deeper zooming capacity. But
I have seen several reports that UF can zoom one or two orders of
magnitude deeper than Fractint.

When I search for midgets, I do it in the simplest way possible --
with outside=iter and inside=0. I never use outside=atan to track
down midgets. I find them instead by searching the fractals
created by the MandelbrotMix4 formula for the critical areas, which
appear as shapes that resemble Mandelbrot buds. When I have found
the proper part of the overall fractal, I search for places where
two similar features come together symmetrically. Then it is a
simple matter of zooming in until a midget appears or the symmetry
bottoms out. I keep the inside set to 0 because when this is
done, it causes tiny holes in the fractal to blink when the color-
cycling mode is toggled. This is another way of finding midgets.

FOTD -- March 01, 2000 (Rating 4)
Fractal enthusiasts and visionaries:
Today's fractal has been named "Fractal Shapes". This is
probably the most generic, all-purpose name I have yet given
a FOTD. But it is a proper name for the scene that appears
as today's fractal.
The formula that was iterated to produce today's fractal is
(Z^1.1)-(Z^(-0.9))+C -- another of those expressions that
wouldn't be expected to produce anything of value.
But fractals often fail to do what is expected of them, and
today's fractal fails in a glorious manner. Instead of the
empty circle that might be expected, we have an interesting
distorted M-set that contains a mass of -- what can one call
them but shapes.
The shapes are visible on Usenet at:
<alt.binaries.pictures.fractals>
and on the web at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
If you decide to take the long route by running the parameter
file, be prepared to wait 1/2 hour.
The weather was sunny and 59F (15C), which brought out the
fractal cats for an afternoon in the sun.
There is no fractal philosophy today, since I exhausted my
philosophical energy replying to several letters. But I may be
recovered by tomorrow, so check in then. Until then, take care,
and if fractals are the answer, what is the question?

I don't believe this to be true. UF doesn't currently support
arbitrary precision. That is coming in the next version. About the
max you can zoom is on the order of 1e17.

Check out Paul Klee's paintings (Swiss painter [1879-1940]).
A web search will find many of his works.
M.C. Escher is, of course, the quintessential example :-)

This confirms what I said. The maximum magnitude Fractint can reach
without switching to arbitrary precision is around 1e13. If UF can
zoom to 1e17, then it exceeds the zoom limit of Fractint by a factor
of around 10,000.
