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

Subject: (fractint) Two Fractint questions

Hi folks,

I have two questions.

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

frm:Colorit1234   (XAXIS){


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

the par file

  outside=summ symmetry=xaxis periodicity=0

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

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

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

  }


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

Should it be in a later release?

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

Subject: (fractint) Carlson-Gallet formula

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

Subject: (fractint) anybody try simplgif?

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

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

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

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

Subject: (fractint) Fractint crashes Windows Explorer

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

Tim,

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

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

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

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

Subject: (fractint) Exploring newl fractals

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

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


Happy hunting, Bud

Subject: (fractint) Fractint as prototype society

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

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

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

It looks like Fractint is far from dead after all.


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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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