    Nah, have some phun. Do a similar image, post it and mention that it was 
done with one of the top guns - that'll keep'em talking for ages... ;)

Splines & macros.  He did say hundreds of thousands afterall....

Shay, you DID use a few #while loops right? ;-)

Disappointed? Nah, delighted! Just shows how little I know about textures ;)

Ah, you got me thinking. If you won't tell us, you'll have to live with
me guessing how it works :) As you mentioned splines: It *looks* like
the straight segments would be the control polygon for a bezier spline
which would be the curved segments. Any good?


Regards,
Florian

That's insane man. I'd say that equals a lot of the work in the POV hall of
fame. Welcome back, too

Nice to see you back.

Amazing!
Bathsheba Grossman-esque.

seriously, if you use "polyhedral symmetry" in a sentence, you just might be
a geek :)

Very good, but that's not the entire answer. The control points for the
final spline were derived from the straight segment corners with Bezier
type math. The curve of the line connecting them was, however, traced by
a new spline formula I invented. The curve had to have a very specific
behavior in order to arch in what I felt was an attractive manner around
the other segments. Here's a comparison image to POV's cubic and natural
spline types.

The work, no. The concept, yes. I did not have access to a computer for
two months, but the elaborate nature of this image is due to the idea's
growing unchecked in mind over that time.

Thank you.
