Thank you David.

I set the jpeg compression to 80% to save space
and it seems that the high frequencies in the 
"texture" suffered a bit from this.

        Thanks!  It's even cooler big.  Such detail!
Iso-surfaces are cool.

        Unfortunatly I can't do iso-surfaces: there
is no Amiga version of MegaPOV*.  Otherwise I wouldn't
have pestered you for the larger render.  Normally when
I see something cool posted here, I try to recreate it
from scratch.
        Once again, thanks for making the larger version.
(how long do these isosurface things take to render, BTW?)

* I suppose I *could* throw MegaPOV on the wintel machine
  at work, but I'de rather keep the miggy and the wintel
  on the same pov-version, for easy file & render management.

I'm happy that someone likes this.

Yes I agree.

Some people in these newsgroups have tried to 
convince me to use MegaPov since April (I think).

Two months ago the temptation had grown so great 
that I installed it.

And one month ago I "discovered" iso-surfaces. 

Now I (almost) admit that I regret that I did 
not install MegaPov earlier.  ;)

I don't remember the stats, but I see now that 
the large one with the wrinkles renders at about 
18 pixels per second (at my 100MHz Pentium).

1024 x 768 / 3600 = 218.5        218.5/18 = 12.1

(So by this calculation it takes about 12 hours 
to render.)

Eerie...like a slowly cooling mass of molten iron-containing rock being 
held in shape by strong gravity and magnetic fields. Looks like it's 
been held in this shape, with those odd floating chunks, for a couple 
millennia.

Your imagination is kind of technical, isn't it ?

But I agree with you - That's the most plausible
explanation for the creation of this stony stuff.

I guess you're right... :-)

And I didn't even go into the possibility of an asteroid/small moon 
collision in orbit around a gas giant...

	If you're interrested, the results are here:
http://www.enst.fr/~jberger/tmp

	(I'm not posting them since they're not *that* different form yours).

	I think the best would be something in between those two with some
reflection thrown in for good measure (ouch the render time though...)

Interesting to see the scene with these glossy 
textures. What are the texture settings ?

And what were the rendering times ?

	Mostly, I replaced the wrinkles with some higher-frequency noise3d and
added phong on one and specular on the other. I don't have the settings
at hand right now, I'll post them tomorrow...

	I don't remember and they wouldn't be significant anyway since I was
working simultaneously on this, my next irtc entry and my cloth
simulator (no, I don't have a cray, just a 333MHz PII...)

	Here are the settings:
* for the bumps I replaced the "wrinkles" term in the isosurface with:
-0.01*(1-2*noise3d (10*x, 10*y, 10*z))

* for the shine: phong or specular 0.5, default phong_size and roughness
