Nope, your wrong about this one. It has been posted by the artist
himself at abpf, and I believe he posted his other two pics also. I'll
let you try to guess again. I don't want to spoil your surprise.  :)

Subject: (fractint) Suggestion for formula writers

I've been wander though a lot of the formulas that orgform has, and
trying them out. For quite some time now, something has been bothering
me about the formulas. After reading one of Jim Muth's explanations for
his FOTD's, it suddenly hit me. I don't know where to start with a lot
of the formulas.

Let me explain what I mean. You choose a formula, then hit 'Z' to add
some parameters. Most formulas let you select real and imag parts of a
few points and maybe choose some functions. But the formula gives no
hint as to a good place to start. When I choose the multirot-XY-ZW
formula, I have no clue what the range is supposed to be for the various
points. Everything starts at zero. I have been playing around with this
formula on my own, and I have never figured out where a good range is.
Finally, after a post recently by Jim Muth, I know what some of the
points are supposed to represent.

I know I can try to sort through the math in the formulas and try to
guess, but would it be possible for people to put in the comments
something like "try this at .5/0/1/-.5/sin". After all, the creator of a
formula should know a good place to start, and maybe even give a hint as
to what the parameters really mean. Some formulas come up with
parameters other than zero's. Is it possible to save a formula with
parameters already set? I don't know about everybody else, but I sure
would appreciate a few more hints in the comments of a formula.

no way - I'm sure one of these must be wrong, although I don't have a clue
about the artist: entries 97,98,99 all seem to be fairly similar (in their
'shapes' not colours). Tthey are all in the 'non-fractint' category if you
want to compare easily.  Given that they were submitted consecutively they
must surely be the same artist.

You're probably right!  I'm sure not batting 100.  Just getting battier! ;)

Subject: (fractint) Weird fractals

Hi there.
    I made a program that generates images related to the M-Set but I am
not sure if they are actually fractals. I believe they are though, and
that they are kind of new. They are certainly new for me cause I haven't
seen any program that can generate these, including Fractint. Anyway, I
have posted some of these images at
http://www.geocities.com/CapeCanaveral/Lab/8660/4fractid.html and I
would like to hear opinions of people with more knowledge about this.
    I will be explaining how I did these if it turns out that the images
are of some interest other than visual.
    Anyway, if you can spare some time, just take a look and let me know
what you think. Even if you think it┤s junk, I'd like to know.
    Thanks.

Yes - I'd second that.  I have tried to do this with my own formulae (which
are mainly colouring methods applied to Mandelbrot/Julia/Julibrot) and I find
the comments useful myself, as I can easily forget what parameter does what!
I invariably find that I can produce much better results with someone else's
formula/colouring method after I understand it, and I get good results so much
quicker if I have some default parameters.

Part of the problem is explaining your formula to someone else - it's very
easy to follow a particular idea so far down the line that when you come to
explain it you've probably forgotten how you got there in the first place.
Trying to explain your idea in comment blocks is also difficult - often you
would double the length of every formula, which could make the formula *more*
difficult to understand.

I must admit, I am finding these guesses as to who created what fractal
most amusing.  Sometimes the guesses are right on; most of the time they're
not. :-)  Linda's guesses were surprising in where she was correct, and
where she was not.

It's a little unfair in my case, though: my entries were among the first
batch I made with Ultra Fractal, so they are different from most of the
work I've done in the past. :)

Here are some wild guesses of who did the Fractint images,

Kathy Roth, Invasion of the Killer Gumballs, because of the name
Linda Allison, Lace, because of the name
Sylvie Gallet, Maelstrom, just because
Paul Lee, Holly, because of the green

The most interesting thing for me has been to try to figure out which ones
Linda Allison did. I have it narrowed down to about 15, which I think is a
tribute to her redoubtable skills and influence. Or my obtuseness?

But I _really_ want to know who did the Beheading of Anne Boleyn; that
one's wicked.

If I have mistakenly associated you w/ any images you don't like, pls. take
no offense.

OK, I like the idea. Here's a few of my guesses:

Alice Kelley - My latest favourite
Sylvie Gallet - Mallorca & The Fly
Earl Hinrichs - Alien Blood
Brian E. Jones - Orange Julius
Jim Muth - We Control
Damien M. Jones - Horta Bones
Linda Allison - Butterflies in Flight

Well, they certainly are different, but I don't know if they can't be done
in Fractint.  Just about anything, except 24bit gradients, can be done in
Fractint.  I couldn't determine the exact nature of them, but they seem to
involve an extreme amount of shearing distortion.

If you did last year's contest the second one looks quite familiar.  =
Not
like contest images but more like what you got to start with.

My guess is that these are done with generalized polynomials like ax^=
4 +
bx^3 + cx^2 + dx + e, with some stretching and/or shearing done.

If you included the formulas in a par file, make sure you preface the
forumla name with "frm:".  Otherwise, the formulas need to be in a .frm
file.

Fractint *can* generate such images.  I've been generating such
images with Fractint for years.

I have checked the site.  The images are indeed related to the
M-set, and they are also related to the Julia sets.  They are in
fact hybrids, with both Julia and Mandelbrot characteristics.

All the Julia sets can be combined into a single four-dimen-
sional object.  All the perturbed Mandelbrot sets can also be
combined into a single four-dimensional object, and these 4-D
objects are the same object sliced in a completely perpendicular
direction.  Your fractals are slices in different directions
through this 4-D object, which I call the Julibrot.

>I will be explaining how I did these if it turns out that the
>images are of some interest other than visual.

The images are quite interesting.  They are a window into the
fourth dimension.

>       Thanks.

I have attached a formula and parameter file that runs in
Fractint and duplicates several of the images at your site.  The
formula also draws many oblique slices through the Julibrot
figure.  Check the Fractal Art list, where I post my "Fractal of
the Day" every day.  I often discuss the 4-D Julibrot figure in
my daily discussion.
