After reading all of you other's's posts, I feel surely inadequate ! ...

Okay here it is:
My name:
For purely superstitious reasons I do not give my name out over the Internet
although anyone with any sleuthing could find it as it is not a secret <g>

I publish a mediocre webpage under my pseudonym at
http://members.aol.com/brockbadge/

I live in Chattanooga, Tennessee.

I have always enjoyed fractals (since I heard of them, anyway. . . see
below).

I discovered fractals on the net, um... sometime within the last 7 days, and
subscribed to fractal-art because I saw that guy's sig ( i can never remember
names ) and got Fractint 19.6 a coupla days later.  ( WOULD have gotten it
right away, but I can't seem to connect to spanky.triumf.ca in the morning :(


And i subscribed to this list because . . . well because I'd like to use
fractint for myself I guess, and to be free of having other people have to
post their .par files for me. :)

"Brock"  --who can recognize the Mandelbrot set now-- <g>

Subject: Re: (fractint) Welcome folks

    Hi Everyone,

    Following Tim's suggestion for introductions. I thought I would
wait for a few days for people to join up before posting. My Name is
Noel Giffin and I've had an interest in fractals from reading about them
in Scientific American in the late 1980's. I played around in fortran
originally creating my own fractal programs, making lots of mistakes
and getting confused at strange results for awhile, before I really
understood what I was doing. I switched to Fractint around version 15
because I couldn't resist the temptation of the formula parser. What,
I don't have to compile every time? From the alt.fractals and then
the sci.fractals newsgroups I came in contact with all these crazy
people who were interested in this subject as well. I started
an ftp archive for fractals in the early days of the internet and
later turned that into the Spanky Fractal Database and webserver.
Thanks again to everyone who has contributed and made it such a
success. I maintain the Fractint web pages as well. Sorry if
people here have emailed me and I haven't responded or not taken
up all your material and ideas. It keeps me so busy, I barely find
time to make any of my own fractals.

    I work at TRIUMF which is a 500 MeV cyclotron on the University
of British Columbia campus in Vancouver, B.C. Canada. I've been working
around computers since my college days in Ottawa, where I learned on
DEC pdp-8 and IBM 1620 machines where 4k of core memory was something
that you could hold in your hands and marvel at the maze of beads and wires.
Life was so simple then. So what if it took two days to punch your
program onto cards only to drop them on the way to the machine room.
So that's what sequence numbers were for?

    I'm really glad Tim started this list. I've never had a CIS
account and I've always felt a little like an outsider, knowing most
of all the ideas and development for fractint was done there. I hope
a little of the discussion and technical fractal topics will now
spill over here as well.

    Cheers,
    Noel

Subject: Re: (fractint) Presenting myself...

Hi Friends

My name is Ramiro Perez, and I am a fractint enthusiast since the days
on where the fractals (like lambdasines in BASIC) take long time to render
and fractint came with a fast generation of fractals (in 8088 computers!)
surprising (and helping!) all of us that tries to build programs for
generating fractals in those days!!


For me Fractint helped me to learn, discover and to explore fractals,
since the days on where fractint fits perfectly in a 360kb diskette.
The formula parser is the best invention that fractint has, and I took
some fractals challeges with it, that you can see im my web pages, such as
the escape time rendering of the IFS (the fern for example) or the Icons
fractals (using zmag to plot the attractor) coded for the formula parser.

Many thanks for making fractint, without it, the fractals don't where the
same...
By the way, my web pages are at:

Subject: (fractint) ParToBat

With all the par files that are coming in through the different
mailinglists, I put all those files including the formula's in one
par file using the 19.6 files.

I use partobat to make a batch file of these par files. The only
problem is that partobat can't recognize the 19.6 FRM: format for
including formula's.

Does anyone know of a newer version, of how to reach the author of
this little program?

<

Michael Peters ([e-mail]) is the author of this very popular
Fractint utility. Concurrent with the release of Fractint 19.6 he posted an
updated version of partobat in the CompuServe forum; his new version recognizes
that entries in parfiles beginning with "frm:", "lsys:" or "ifs:" are not image
entries, and therefore does not write batch commands to draw them.

I don't know if this latest version has been sent to Noel Giffin for inclusion
in the Spanky Fractal Database, but if not, it should be.

Hi,

My name is Nicolas Guerin. I live in Grenoble, France, close to the
French Alps. I've been a fractal enthusiast for a long time now,
beginning at the end of the 80s on my Amiga.
I am mostly interested in fractal programming: rendering techniques,
code optimization, etc.

I consider Fractint as THE fractal program, even though it is
becoming somewhat outdated: no 32 bits support, dos only (and UNIX
port), and basic user interface. I guess those issues will be
discussed in this mailing list ;-)

Hi Folks,
   Just to clear any misunderstandings, there is no 'jay perret' on this list, that just me
using someone elses copy of netscape to send mail and forgetting to fiddle with the ID!
So fear not, I'm really me, not him, and he's not me, or something.....
(though there is another Robin Bussell in England who teaches computing at the university of
Hertfordshire... he's not me either, not tall enough :-) )

meanwhile....

>>Do You know when the next release of Fractint will be? I really liked

>>Thore Berntsen

Thanks Thore! Well it's not going to be *too* soon I'm afraid but things are now emerging
from the 'quick hack' stage (well 'two year fiddle' really ) and we're dealing with issues
like stopping the evolver crashing everything when it's told to do something illogical,
stopping it eating up all available memory, allowing save/resume operations and so on... in
short all the things that make it useable by anyone without detailed inside knowlege of how
it works (which is the whole driving point behind it ). I'm not going to make any promises
as to time as that would be a foolish thing to do where software development is concerned..
just ask Bill Gates :-)


Cheers,
     Robin.

Friends,

  I'm doing some work on the memory management code in the formula parser. This
would be a good time to make known any ideas you have for the parser. As with
all wish list items, there is no guarantee that the proposed feature will be
added right away, but at least I may be able to complete the work I'm doing now
in a way that won't preclude implementation in the future.

What he said!  I'm Kerry Mitchell, currently in Phoenix, AZ.  Been doing
fractals since that same SciAm article.  Started with a Commodore 64, then
graduated to computing fractal datafiles on a mainframe and downloading
them over a 2400 baud modem to my Amiga.  Now, I use mostly Fractint and
my own codings (in QuickBASIC), along with Piclab (image processing
program by the Stone Soupers). I'm an aerospace engineer by training and
work as staff scientist at the Arizona Science Center.  I've had the
privilege of doing several museum and gallery shows, and have sold a few
images for use on bookcovers.

When I first found Fractint, v12, I thought that Stone Soup Group had
foolishly mis-typed--it was *obviously* version 1.2; no good program could
have *twelve* versions!  :-)

Greetings everyone, I am Jim Muth, fractal fanatic, graphic artist,
writer and sometimes philosopher.  I reside in a large, (too large
in fact), East Coast city of the USA, where I spend most of my
idle hours searching for those elusive great fractals.  Those of
you who are members of the Fractal-Art mailing list are already
familiar with my work.  It appears as the "Fractal of the Day",
which I've been posting to that list for several months, and will
continue doing so.

But in addition to the artistic aspect, fractals also have a math-
ematical and philosophical aspect, and it is these aspects which
I will emphasize in my posts to this list.

Like many of you, I learned about fractals from the articles which
appeared in Scientific American Magazine in the 1980's.  But it was
not until 1987 that I actually began working with them on a clunky
old 8088.  Even now, I am still using a 486, but I am ready to
purchase a new machine as soon as I determine which processor runs
Fractint the fastest.

My particular fascination with fractals lies in the fact that they
are multi-dimensional.  The assemblage of Julia sets comprises a
four-dimensional object known as the julibrot figure.  The assem-
blage of perturbed Mandelbrot sets also comprises a four-dimensional
figure, the same julibrot figure sliced from a different direction.
But in addition to these two directions, there are four other
perpendicular directions in which the julibrot may be sliced in
two-dimensional slices.  It is these other directions, as well as
the oblique and skew directions of the julibrot that I am most
interested in.

Before I go, I'd like to tell my most wished-for Fractint feature --
a simple text editor included as part of the program.  This would
eliminate the constant switching of programs when fine-tuning
formulas.

See all of you soon.  Take care.

Hi, my name is Bill Decker.

I've been using Fractint on and off since the late 80's. Fractint has
taught me lots about fractal math as it drew pretty pictures. It's good to
see that there is now a list devoted to the program. (Thanks, Tim.) I hope
to learn more as questions are asked and answers are supplied on the list.

My interest is in Iterated Function Systems. IFSs are something that
Fractint is not quite as useful for as it is with some other fractal types.
This isn't a complaint, but it explains my on and off Fractint usage.
Perhaps, as I get the time, I will propose some possible improvements to
Fractint in this area.

In the meantime, I have been working on my own software to investigate
IFSs. While this means that I don't have as much time for Fractint as I
used to, my continued interest in Fractint has at last moved me to add a
feature to my IFS software to produce 19.6 par files. This will allow me to
share my IFS creations with others.

Anyway, IFSs continue to hold my fascination and I look forward to running
into other IFS aficionados on this list who might share their IFS
experiences with us.

Subject: RE: (fractint) Welcome folks

My name is Gene Peresich.

Somewhat new to FRACTINT. Primary interest is fractal analysis
methods, with some fractal image generation work.

I'm looking for a source code - preferable C or FORTRAN - which
computes fractal dimensions of 2-dimensional images - any method(s),
but box count preferred - which I could adapt to incorporate into
another program.

Can you help? Thanks.
