Isn't it beautiful ? ;)
Thats a 33%-version of the final image.
I traced it in 1152x864 with AA0.0 (about 12h)
It gives a nice desktopwallpaper.
If there is interest, I can post it fullsize and less JPEGgy...
(probably PNG)
So far ...
Comments welcome... (don't ask for the black thing ;)

The smooth circumference doesn't go well with the rough surface. It
needs a "displacement_mapped" isosurface.

it was my intention with the first versions of the pic, to understand
the working of normal-maps with radiosity...
Now it is ment to make the image interesting! ;)

Awesome. How can I get the larger (full) version?
Congrats,

Or, how portable is the source? What mega version?
Nice abstract work, BTW

You only need the Radiosity of Mega ... (I use 0.7)
I don't know what changed to this in the latest versions of Mega...
AFAIK not to much, so it should go with MP0.1

have you considered making this an isosurface instead? the isosurface
shadow and profile would both show the crackle detail and also might
make for an interesting radiosity comparison. unless i'm mistaken, in
order to get a ball the same size, you start with a smaller sphere and
then add the crackle function to it.

Yes: I considered this option ...
then I looked to the bottom right corner, where the tracetime
is: it started with 12h.
BTW:Of course PPS was >1; this would be an argument FOR isosurface ...
