Well, I did my duty and entered the room about 8:00pm Eastern time
but I was all alone :(
I've never tried a chat room before so perhaps I did something
wrong. Different rooms kept appearing and vanishing from the
left side list. Tried ringing the bell and was informed that
"Jax rang the bell". Yipee. Waited about 5 mins and then tried another
room just to find out if I was doing things properly but then the
Fractal room disappeared. Didn't know how one properly leaves
such environs so I just split to another url. Frankly, the thing seems
like a rather inefficient and frustrating way to communicate.
Probably just me... fractals confused me the first time too
(still do, actually :)

Where did you hear the Factal music? Was it a downloadable midi, wav or some other file?

Subject: (fractint) Fractal music?
I just had a chance to hear some fractal-generated music. The stuff sounds
really cool. Kind of mystical. You probably won't hear any CDs of it, but it's
cool. Does anyone know if there's any chance that Fractint is going to be able
to generate fractal music in the near future? For that matter, does anyone
know HOW to generate fractal music?

Hi;
I saw in an earlier posting that you were loading colormaps from "E" + "L"
instead of the "C" + "L".
As I recall I got some leftover garbage on the screen from using "E" + "L".
I hope that helps...Jim

I've got some super fractal music at my site at http://www.dorsai.org/~arch.
It is written in the shareware program Art Song in MIDI format, then
sequenced in Orchestrator Plus and/or Cakewalk. It is wholly based on
fractal data (RGB values) derived from fractals drawn in Fractint.

Subject: Re: (fractint) blakes fractal chat room
Jack...
Actually it's a pretty good way to communicate with the right
software.......I prefer mirc or pirch to a browser. If you have irc
software...you can be notified when someone you want to talk to shows up
rather than having to hang in a room....it's great for real-time help with
programs that run under windows and transferring large files back and forth.
The down-side is the one you ran into....people have to be on the net at
the same time.....when we get Fractint that runs under win95 and NT, we can
run a chat program as an ap while we wait for our fractals to materialize.
I noticed from the Fractint wish list that the thing most folks want is a
fully featured Fractint which is stable under NT.
SHORT TERM WISH LIST ITEM .....a way to compare color maps, overwrite
existing color map names, comment the maps (similar to the comments in the
pars) and select them for deletion.

F.O.T.N. (Fractal of the Night) 19 Jan 1998 (Potatoe)
Tonight's fractal, discovered near last night's Elephant, looks a
lot like a potato. It is from the MSet, corresponding to the map of
the Julia sets computed from a formula by Michael G. Wareman. This
comes from one of the branches on the period 5 bud on the MSet
butt. Nearby midgets are more normal looking, but not all. I found
a second potato on another branch. You never know what you will
find, digging around in fractal land! The formula is
z = p1*(z2 + c)2/((z2 + c) + p2) + c
with p1 and p2 equal to 100.
Here are the Fractint parameter files.
Enjoy

Since I have joined this group, I have had mixed feelings about it.
Bad: there's a lot of traffic (on- and off-topic).
Good: there's *so* much free data!
Bad: I'm developing a case of fractal time compression like you
wouldn't believe (then again, maybe you would).
Good: I'm cranking out lots of (IMHO) good images from other peoples'
formulae!
Bad: my life's disappearing into a fractal black hole.
OT1 (off-topic #1): Howdy Don, didn't know you were on!
Thanks to Morgan L. Owens for his 1/16 astrophysical formula post.
Although I know the meaning of the formulae are seriously perverted
by plugging in complex numbers, I can't complain about the results.
Here are two .pars, one for the OT, the other purely gratuitous. Both
of these are done at critical points; for ap-102 (which reminds me of
"magnet" fractals I have seen/done) there are a whole lot of these

Subject: (fractint) Monday - From Paul Carlson
Paul asked me to post.....
*******************************
I think Kerry's extensions to the bubble method are very
ingenious, especially the swirls. Seeing her formulas
finally got me to translate my bubble method into a
Fractint formula. If anybody's interested in how I came
to develop the bubble method about 2 1/2 years ago, my
paper, "PSEUDO-3D RENDERING METHODS FOR FRACTALS IN THE
COMPLEX PLANE" which was published in the journal
_Computers & Graphics_, Vol. 20, No. 5, pp. 751-758, 1996
gives all the details.
Anyhow, here's the formula and 4 par files to try it with.
The par file bubsmnd2 is the same as bubsmnd1 except for the
value of real(p2) which was increased so that the bubbles,
instead of being tangent to each other, are squished together
(this also required some minor editing of the colormap).
I tried to make the formula as clear as possible. I'll be
glad to answer any questions about it.

Four years ago this week, I purchased a combination PhotoJet Printer
Board for my LaserJet 4 and a PhotoJet Circuit Board for my computer. It
was manufactured by XLI Corp of North Billerica, Mass. It cost $895
before the added freight charge. The software I use is Picture
Publisher.
I still use PhotoJet today. It prints out in gray scale at 2400 dpi on
8.5 x 11 inch paper. The results of the output are stupendous. My
fractal images have a photolike quality to them in the printouts.
I don't know if the company is still around, since I haven't found the
need to contact them since I purchased the circuits boards.

Maybe! But the music doesn't come easy or fast. Thanks.

I downloaded the par files without difficulty and there was
no =3D problem. It gives an error message for the colors
and then runs it in the Fractint default palette with an odd sort
of dithering, which I assumed is how the Truecolor is rendered
in the 256 color palette. I have had some trouble with getting
pars into Fractint in general, so if anyone is getting something
different, please let me know. Thanks, they are truly great
images.

Here's another coloring method that I've used.

Ghost
In the ghost coloring scheme, you can make the fractal appear or disappear
against a gradient background. It is based on the iteration smoothing
routine of Linas Vepstas, and uses an adjustable parameter to determine
how prevalent the fractal appears.
The iteration smoothing technique works by letting the iterate go much
beyond the required escape radius of 4, and converting its geometric
growth into a real number. When combined with the original iteration
number, the result is a real number that can be plotted continuously
with the decomposition (or outside=real) methods. Here, the smoothed
iteration count is scaled and made the polar angle for the decomposition
coloring.
The backgrounds for these images are gradients (using smooth color maps),
running horizontally, vertically, or in rays from the origin (point 0+0i).
In the latter case, the background is simply the polar angle of the pixel,
which may or may not be centered on the screen, depending on the zoom of
the image. In the former two cases, the gradients are dynamically set to
use the full color range irrespective of the pixel coordinates. In any
case, the background is represented by an angle, for use with decomposition.
Given angles for both the iteration count and the background image, they
are combined using the "ghost" parameter. The iteration angle is scaled
by "ghost" and added to the background angle. When the ghost level is
set to zero, then only the background angle remains, and that is what is
shown in the image. Increasing the ghost level results in the background
being subtly, then significantly, perturbed by the fractal. The disturbance
starts with the highest iteration levels first (except that interior points
are assigned 0 iteration, to clarify the boundary), and propagates to the
lower iterations as the ghostliness is increased. The effect on the image
is to see the background gradient smoothly displaced by the fractal, but
to not see the fractal directly.
The best uses of this scheme seems to be on Julia dust (non-connected)
fractals, in which there is lots of "empty" space for the background to
show through.
