    The LightJet system is still available from:

    Cymbolic Sciences who build them.

    From their website it looks like there are about 400 machines

Subject: Re: (fractint) Tracing l-systems - clarification

Its relatively straightforward to write L-system code in postscript
directly.  Of course, you have to be a programmer to do this.

In article <[e-mail]>,

I think what keeps throwing other people off is your use of
terminology.  Traditional use of the word "render" means to turn it
into pixels on the screen.  So once you render a vector file, its
turned into pixels and there will always be jaggies on your pixel
rendering unless you used a nice anti-aliased line implementation.

I wouldn't use the word "render" for this.  Rendering produces pixels.
Generally people talk about this process as "output", i.e. "output the
L-system as a vector file".

There are a variety of L-system programs out there.  Writing an
L-system expansion in PostScript is rather trivial, as I say, if you
already know PostScript.  I've done it myself and its only half a page
of PostScript code.  Of course it takes forever for the printer to
rasterize it at high expansion levels because of the nature of
L-systems to produce huge amounts of geometry.

Funny you should say that but I've got a search going on tracerlock
(www.tracerlock.com) which reports all new occurances of the word
fractint on altavista, it's great for keeping tabs on new galleries and
such. Anyway it recently threw up this address:

http://perso.club-internet.fr/gravert/galvech/tinting.htm

Where someone has independantly coined the word to describe a
printing
technique which uses naturally generated fractal patterns.

Cheers,
          Robin.

Subject: (fractint) deepzoom animation

Hello all,

(my first post)

I'm generating a complete zoom from the full mandelbrot down to a deep
zoom.

Using an image from the 'Deepzooming with Fractint' web page as a
starting point, (the one by Dewey Odhner called 390m586) mag
8.166x10^58, I started zooming out step by step. I've generated a par
file with 3872 pars (split into 4 since Fractint limits to 2000 pars -
incidentally Fractint will give an error when loading a par file of
exactly 2000 pars, even though it does give all 2000 - a minor bug, I
ain't complaining about such a wonderful product! Also, the 'int'
definitely stood for integer when I first started back in the days of
386s.)

I generated every 100th frame to get an estimate of total generation
time which came to about 1600 hours.

I started generating each image a 640x480 (on a PII 400) Quite
straightforward with simple repetitive autokey files.

Over the past month I've generated the outermost 2700 frames. I estimate
another 1000 hours to completion.
To add interest my zoom rotates 1 step, colour-rotates 1 step and
increases the maxiter by one each frame. The resulting animation so far
makes a very nice avi.

If there's interest here I'll post more details, including the basic
'anatomy' of this deepzoom.

If anyone wants to help I'll post them pars.

I'll be adding details of this (and other less deep zooms that I made
last year) on my website and will let you all know when I upload them.
My other zooms (3 barnsleys, a lyapunov, a julia and 2 mandels) were all
under 1000 frames and took only a few hours to generate as they go as
deep as or much deeper than the point at which arbitrary precision is
needed.

Incidentally, to add to a point of discussion that was ongoing recently:
I found that in my current deepzoom, 8.139x10^12 wasn't arb-precision
(taking a few seconds) while the next frame 8.444x10^12 went arbitrary
and took several minutes.

Last month I had the fortune to be performing my video art at a club
that had a 360 degree video screen consisting of 16 LCD video
projectors. These fractal zooms (among other stuff) looked fantastic!
(more details of such stuff in on my web-site, look for Optic Alchemy)

Subject: Re: (fractint) Speed and precision in UF compared to Fractint

David,

 - Windows9x is still basically 16-bit with some 32-bit
 - elements. You need a real 32-bit OS like Linux or NT for
 - 32-bit-optimized processors.

Please do not spew biased misinformation on this list. If you had asked any
programmer who has actually WORKED with Windows 95 they will be quite happy
to tell you it is primarily a 32-bit OS. There are portions which still use
16-bit code, but they aren't nearly as huge as your comments would
indicate. Programs do run in protected, isolated memory spaces, using
32-bit memory management. 16-bit segments are for all practical purposes
gone. Core processes are run as 32-bit, it is mainly portions of the GUI
which are still 16-bit, plus some compatibility code which lets you run
more DOS stuff than you can in NT.

Your platform advocacy probably belongs in an advocacy newsgroup, not on
the FractInt mailing list, IMO.

My opinion is that the name will be Fractint forever, even long after we have
removed integer math :-) The reason is not that I invested $75 is
the domain name, it's just that that's the name of the program.

Then again, who knows, anything can happen!

It does occur to me that Bert Tyler named the Windows version
"Winfract",  but even then we understood that this was the windows
port of Fractint. So who knows? :-) But I'm not inclined to change
the name of the program just because integer math is gone.

One of the great things about about a group project is that we can
decide stuff like this together!

Subject: (fractint) FOTD, 15-03-00 (FOTD for March 15 [5]) (c)

FOTD -- March 15, 2000  (Rating 5)

Fractal enthusiasts and visionaries:

I see that the FracTint vs UltraFractal debate has heated up
again.  Of course, it's no secret that I'm a Fractint user, and
have been since version 2.1.  I still have that early version
stashed away in a remote directory of my old 8mhz 80286 machine.
The executable file of that ancient version is named
fract386.exe.  The file size is a whopping 32,541 bytes, and the
date is 10-23-88 -- 9:06p.  Things have come a long way since
then.

Actually, I feel that the big debate is a bit overwrought.  I
see Fractint and UF as complementing each other rather than
competing, with Fractint emphasizing the mathematical aspect of
fractals, and UF with its multiple layers emphasizing the
artistic aspect.  My view is pretty near the middle in this
debate, but if asked to choose a side, I would side with the
Stone-Soupers, since I am more interested in the math than the
art.

Today's fractal comes from the formula 4Z^(-2)-5Z^(-1)+C.  The
area in which the scene lies consists of features that resemble
elephants with heads on both ends.  The parent fractal is rather
interesting, with a train of Mandeloid fragments shrinking to
infinity.  This fractal definitely deserves the further investi-
gation that I will give it tomorrow.

I was unable to think of a name for today's picture, and finally
settled on the technical description "FOTD for March 15" as the
name.  The image, which originally was a bit drab, was given
post-processing in a graphics program to liven it.

The parameter file takes about 10 minutes to fill the screen
with pixels.  The image file, which already has its pixels
calculated, is available for download at the Usenet site:

          <alt.binaries.pictures.fractals>

and at the Web site:

          <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>

The fractal weather was notably dull today.  The partly cloudy
skies and temperature of 57F (14C) were perfect for the fractal
cats, who passed the afternoon on the porch.

I was too busy today to philosophize, but I'll try again
tomorrow.  I certainly have a lot more to say, if only I can
find the time to say it.  Until next time, take care, and put
your best fractal forward.

PS  I think I've found a serious bug in the float-only version
of Fractint patch level 9, which I'm testing.  The bug involves
writing to the parameter file.  I'll check it further tomorrow
and report on what I find.

Thanks Phil,
I stand corrected on my use of "render" for "output".  I suppose that does
explain a lot of the confusion.  Thanks also for your advice on Postsctipt
programming - never been there or done that, but it sounds helpful.
... Of course I had to ask for the lazy way out first, which was why the
questions about taking an actual L-system programme (the few lines of code
in each named entry of any Fractint .l file, not the .gifs or other bitmaps
one can produce from it), and outputting THAT to a vector file, aside from
programming it oneself in Postscript...  The silence means either my
question wasn't understood until now, or there's just nothing out there
which can do this.

If you do decide to have a crack at this, I'd be interested in what you
come up with.

If you recall the Lparser program I sent you, I recalled (and just
confirmed) that running it with an -l command switch you cause it to spit
out the final (fully expanded) string from which the drawing commands are
derived. You might find this useful in a Postscript project because it
would allow you to try converting real lsystem strings into Postscript
commands without having to write a Fractint lsystem entry parser first. I
suspect the trickiest part of the job would be fitting it to the page (or
at least scaling it in some useful fashion).

Of course, like Phil said, these things have a _lot_ of geometry, so you
might rather want some standalone program that would do all the lsystem
parsing and iteration stuff, and just write the final results (say, a list
of line segments) to the file, rather than hope that whatever's
interpreting your Postscript is up to the task.

Also in passing, I thought you might also like to be made aware of
http://www.wotsit.org/ - a file format archive, including things like
Illustrator, EPS, DXF and other vector image formats.

Also also in passing, I note that Phils says the word is "output" instead
of "render" and then later goes ahead and says "rasterize" anyway :-)

I have used the current version of partobat on a Win95 system in a DOS
window.  I presume it would work on Win98.  I think I found it or a link
to it on Jo Weber's web site.

http://www.joweber.de/

If you don't find it there, email me off list and I'll send you the ZIP
file.

Jon,

You mention the divide and conquer methodology using Fractint. There is n=
o
longer a need for that, as Fractint v.20 (+) has the ability to generate
very large fractals without dividing. I realize there may be other reason=
s
to divide - such as using many machines (as I recall you used to do). I
just wanted to point out this new capability with Fractint20, in case you=

aren't aware of it.

I have generated images of 16000x12000 during the testing of the feature.=

The latest version of 3.3 (October 10, 1999) is the only one that I am
aware of at this time:

    Yes, it has worked fine on both releases of Windows-98.

Subject: (fractint) Float-only version par-file broken

There is a serious bug in the just-released float-only version
of Fractint, which causes the center coordinate data to be written
incorrectly to the parameter file.  This bug affects images with a
magnitude greater than 1e006, where the center coordinate data is
rounded and truncated to 6 decimal places as it is written.  The
corresponding version (20.0.9) with integer math appears to be
working correctly.

Guy,

There was a problem with earlier versions of partobat - it wouldn't run on
computers faster than 200Mhz because of a bug in the Pascal compiler. I don't
think this had anything to do with Windows. This was fixed in a later version. I
see Ken has already responded to you but if you can't find the latest version,
email me and I'll try to dig it up for you. I think the version I have is 3.5.

Nick

The version of Partobat at Spanky did not run on my PIII.  Jo Weber's site
has two more recent versions at:

and the latter of these ran fine on my machine under W98.

Anyone who finds bugs specific to the float-only version can email
the details to me. It's best to give me specific details (as simple as
possible) for duplicating the bug - usually a PAR - and tell me
exactly what to look for. The float-only  version probably has bugs,
but probably wouldn't be too hard to straighten out. I appreciate
efforts by users to look into this.

An easy way to test would be to run a bunch a PARs using
something like PAR2BAT. The results obtained with the two
versions (regular and float only) should be the same.

Jim, in the case of the problem you found, I could probably figure
out the problem from what you said, but I'd prefer a PAR and a
detailed set of instructions.

Thanks!

Tim

Yes, integer math is still in the regular 20.0.9 version. I lobbied to
take out integer math earlier, but the team didn't go along with me
<grin!> My guess is that the DOS medium memory model version
will always support integer math, but integer math will die when we
abandon the medium memory model. I don't expect the traditional
fractint to develop much further. Change to a better platform is
already long overdue. (Xfractint has never supported integer math.
Winfract did, but that is because Windows 3.1 applications could
be compiled with the medium memory model. Windows 95-
specirfic applications can't.

I hope that the integer math option will still be there somewhere...
Those poor old 386's and486sx's need something to do to keep them
feeling like they are needed!!!!

Theres nothing they like better than sitting in the corner calculating
fractals all day every day... they (virtually) purr...
