Thanks Andrew, I'll look at the code and use it as a starting point
and at Mike's

I wanted to modify it to the basic Mandelbrot so I could try and find
the Buddhabrot. No luck as I can't code to save myself. I did come up
with this though and I quite like it. I think I'll call it the
Sumobrot. I used Mike's modification to create 3 df3's and played
about with emitting media. Let your eyes go slightly out of focus.

Wow.  Miss a few days, miss a lot.  I'm searching but not finding examples
of "Mike's modification" or "df3s" and I really want to figure this out!

So, please help.  Source perhaps?  Or of your less out-of-focus version
below?  I haven't puzzled out df3's yet.  Maybe this example would soak in.

Thanks

(Really cool by the way, yours and Andrew's and as always, Mike's)

Mikes Modification (sounds important like Tim's error in fractint) was
to use Andrews's formula and use it as a pigment.

Of course! It is a three step process.
I added a variable to the formula and created an animation. Then using
tga2df3 I created a df3. The less out of focus image had more tga
images. 120 in the one you asked about. Mikes Modification uses a
three colour, colour map. So I modified that and produced three
monochrome df3's, Red, Yellow and Blue. This took 4 and a half hours
on my Laptop the df3's are 84 Megs.
The POV file to generate the image was made in Moray so the coordinate
system is not the same as in POV and there are INC and INI files. I
have found that there are 4 interesting positions for the camera and
they are symmetrical about the origin. 
BTW using a sphere instead of a box produces in interesting image but
I've not found anything worth posting.

I'll post the source in Povray.biniaries.misc as a zip file shortly.

Thank you, I'm flattered.

Andrew, if you are still following this thread. Can I use your code for an
entry into the IRTC?

Sure - be my guest! ;-)

Thanks I'll credit you if you want to be associated  :-)

>(Erm... did somebody die and leave you a CRAY?)

No, I used Mike's "pigment function" idea and modified your code to
generate a series of images with different values of "C". 
I like the simple way I said "modified your code" I got the animation
OK but when I tried to change it so it rendered the "normal" quadratic
Mandelbrot I got completely lost and could not do it. My lack not
yours.

        Stephen

Ah, right. Much faster than an isosurface...

Yes especially since I am creating DF3 files with 240 "frames" times
3. It is taking between 8 and 12 hours as it is. Isosurfaces would
take forever.
