Here is my first post to p.b.i. I couldn't think of anything better to do
than use something I was working on related to pyramids. And, while
technically this is NOT a sphere, it is a rough approximation.

Nice! Certainely not your 1st image :)
I can hear the rumble when it rolls
Do you prefer gif to jpg?
And last question, is there normal in stone texture or is it really
irregular?

Please post the code for the sphere. I really would like to know how to
do that. Thank you.

Thanks! I have been doing CG since 1988 when I was in grad school, taking
computer graphics classes as part of my required courses for a masters
degree, specializing in artificial intelligence. (I still don't understand
the relationship.) In the second class, we wrote a "ray-caster" and added
features over the course of the semester, and I was hooked. Then I found
POV (or its predecessor) on Compuserve, and have followed its progress ever
since.

gif was just smaller, and I didn't want to get flamed for uploading a file
that was "too large", as this is my first post.

Actually, the stones are isosurfaces. The pseudo-sphere is generated by
some nested loops which determine the x,y,z coordinates of each stone, then
generates the isosurface object with the iso function altered to produce
varied effects on the stones. (Actually, this just generates half of a
shell, and I duplicated and rotated the first half to get the second
half.)

Okay, the source is posted in p.b.sf, but I have to confess that I was too
lazy to make the sphere properly, and if you look at it from the top, you
will see gaps near z = 0. I'm sure there is a relatively easy math fix,
(probably using polar coordinates, or a different set of steps) but I just
wanted to post the obligatory sphere with plane.
I was also flirting with creating the stones the appropriate distance from
the center, and then just rotate them, but I liked the way this looked
enough to not even try.

Thanks. Now to study and try it out...
