The story:
I decided to do something *without* isosurfaces and *without* radiosity and
therefore played with some superquadric ellipsoids. But of course i could not
resist trying out how it looks with radiosity - and it really was much better,
so ... :-)
concerning isosurfaces - rendering time was already 4h30min ...
The textures were made using displace warps, I do not like the gray/blue one
right now, so it will probably be changed.
Comments, etc. welcome
Christoph

Just in case you didn't know, which it seems you don't, isosurface
superellipsoids render faster than the real superellipsoid object in
POV-Ray... Nice image.

Neat, I like it. Don't like the blue and grey one though. I wonder how it
would look with a chrome texture.

I know, and just checked it for this scene, it's about 25% faster here (without
radiosity), but I originally meant using isosurfaces with some pigment function
instead of the normal statement and that would be much slower anyway.

Thank You.

Thanks, i thought of something metallic too, but i first have to build up
something behind the camera to have a nice reflection.

That's a good thought, maybe try throwing something unexpected into the
reflection.

Nice image, very different but attractive. I like the positioning and
apparent random nature of the SEs.
I would love to see the source for this.

Thanks, but different form what ? :-)

The positioning/randomizing is really not that difficult:
#macro Var_SQ()
superellipsoid {
<rand(RX)*0.99 + 0.01, rand(RY)*0.99 + 0.01>
material {
M_warped
translate <rand(RX), rand(RY), rand(RZ)>*10
}
}
#end
union {
#declare CnY=0;
#while (CnY<60)
#declare CnX=0;
#while (CnX<60)
object { Var_SQ() translate <CnX, -CnY-2, -1> }
#declare CnX=CnX+2;
#end
#declare CnY=CnY+2;
#end
}

That's a funny idea, but i thought about sticking to superellipsoids.
