This is the same type of Iso as the in my
"Spherical Splash" image:
news://news.povray.org/3AA41C10.55F23524%40hotmail.com
(Sorry, but no radiosity this time.)
Now I have rotated the pigment in the same
noisy way as the iso is rotated.
But I think that I could have achieved the
same effect for this shape if I had made
the colour of the pigment change as a
function of the distance from the sphere
centre (radially changing pigment colour ?).
Comments are welcome.

Thank you !

The shape is done in MegaPOV by first randomly
displacing the surface of an iso-sphere with the
the noise3d() function, and then using 3 other
random functions to feed a general rotation
function with random angles so that it rotates
each point on the iso-surface randomly around
each of the x, y, and z -axes.
You may look at the source code that I posted
to povray.text.scene-files 10. March this year:
news://news.povray.org/3aa9fa11%40news.povray.org
news://news.povray.org/3AAA03E6.6ECB760B%40hotmail.com
The pigment is done with a pigment function
that are fed with the same rotated coordinates.
I can post the source for if anyone is interested.

Uhhmmm... Unfortunately I only have access to my
private PC right now. And it's WAY too slow for
a radiosity version. (Maybe I'll do it on my
much faster PC at work when the easter is over.)

Until now I've resisted the urge to use megapov. But this image has
converted me :)
It's gorgeous. Can you animate it?

Hehe. This sounds a lot like me. I managed to
resist the temptation to start using MegaPOV
from March to October last year :)
> It's gorgeous. Can you animate it?
Thank you !
Yes it can be animated; e.g. by slowly shifting
the origin of the rotation functions or the
first surface-displacement function. And maybe
it would be cool if the colors were cycled in
a "pulsing" way from the inside and out at the
same time.
But now I'm dreaming... I don't have a PC to
do such stuff here at the moment :(

You did it again: very very real-looking, though i don't expect to see
it around ever! Very good :))

I don't know if you read povray.general, but I just upgraded my machine,
and want something to test it on. Fling me the source to my email, and
I'll have a go at rendering it and posty the resultant .mpg to p.b.a.
Bye for now,
Jamie.

Thank you very much for your offer Jamie.
I've been out for a couple of beers,
so I'm not able to make POV-animations
at the moment =)
Now I'll have some sleep and then I'll
see of I can find time tomorrow to
refresh my animation skills and code
some animation of my iso-mess.
