I wouldn't say so, no.. but some crystals scattered around might look
cool (with dispersion and all that fun stuff).
Of course, you'd have to do actual modeling for that. *horror!*
I wonder what this would look like with radiosity...

Interesting stuff, these iso-mazes. Good job on the lighting, gives it depth and
sort of a mysterious feel. Will the source be de-classified?

This is not fair ! Now I wish I didn't know your
rendering time for this image. :(
I like the texture. How did you do that ?
I envy your possibilities to explore these worlds.

Looks like some kind of revolting organic microscopy... :)

I had a slow-assed P-200 until just a month ago. I feel for you.

I used pretty much the same method you used except I specified
a granite piment pattern and then used multiple colered lights
to give the actual color to the scene.
object {
Toroid_Noise
pigment { granite
color_map {
[0.0 rgb .35]
[0.5 rgb .50]
[.75 rgb .35]
[1.0 rgb .75]
}
scale .5
}
normal { granite .25 scale .35}
no_shadow
}
> I envy your possibilities to explore these worlds.
I envy your ability to understand isosurfaces and the math
behind them. I merely took your work and expanded upon it.
Have you tried feeding it a quilted pigment yet ? I have been
getting some interesting results using various slopes in the
pattern.

Thanks.
> Will the source be de-classified?
I based a good portion of this on Tor's toroidal iso-noise
source posted a while back. I then modified it to make it
my own. Unfortunately the original source for the image I
posted has since gone through serveral revisions and I doubt
I could recreate it if I wanted to. I am having way too much
fun with this stuff ! :)

Thank you Ken.

When I saw Greg M. Johnson's Cell city I thought that maybe
it was many pattern types that I hadn't seen yet.
So I browsed through the documentation and found the quilted
pattern, which I had never used before. I did a little test
with this pattern as well, but I was to tired to actual read
the documentation for this pattern. So the results that I got
wasn't what I thought they would be.
But now I'm very interested to see what images came from
your experiments with this pattern.

It was mainly designed for use in normal statements which
coincidentally makes it ideally suited for isosurface work :)

Ooops... I have been trying so many things, and not saving
them, that I really have no working examples to share with
you. Last night I started playing with patterned pigments
and isosufaces. Wheee.....
