I don't know what you mean by 'feeding' but it looks interesting.

This one would fit in the X-Files series.

Nice one and somewhat scary

Thank you for your compliments.


To Christoph Hormann:

By feeding I meant that I gave the values 
that were returned from 3 different calls 
to the noise3d function as inputs for the 
x, y and z parameters in a call to a torus 
function.

For some reason, just as I was drifting off to sleep last night, this image
popped into my head, along with the thought..

Very cool.

Could you render a larger version?

I have enclosed a 1027x768 version.
(This time with "wrinkles")


If you want another size or an image without 
the "wrinkles", then I can post the source 
so that you can render it the way you like.

Hehe 

=)

Or maybe it is a lava lamp graveyard ?

(Note that the lava isn't moving.)

Did you notice the bug-eyed-monster in the center of the image
about 2/3 down ?

I have been staring at the image for some 
time now, trying to see your monster, but I 
can't spot it.

Please show me.

It's not *my* monster :)

Ok. See attached and use your imagination. Reminds me of a famous

I have now posted the code to povray.text.scene-files:

news://news.povray.org/3A08883F.ECDFB741%40online.no


If your idea results in something nice or interesting,
I would be glad to see the result.

Oh yes - I can see him now. 

Strange that he is in there...

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'm happy that someone likes this.


> Iso-surfaces are cool.

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.  ;)


>...
> (how long do these isosurface things take to render, BTW?)

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...)

Thank you for showing me these Jérôme !

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
