I'm back from Thailand.  Just did a quicky anim. this Xmas eve morning with 
my glass marbles and SimBalls.  I really like that simple clean Povray 
glass look.  It kind of looks "Christmassy" with the all the colors.  
Camera should perhaps be pointed a little lower, but I'm lazy.

Nice work on the SSS stuff in p.b.i., and I love that anim. Tek!

BTW, I posted the source for my SimBalls Povray SDL code in p.b.s-f about a 
month ago if anyone is interested.  Same basic code was used for this anim.

Extremely cool-- but they are bath oil beads, not marbles, based on how they
bounce.

Thanks.

Oil beads, Perhaps? It may be the fact that the animation is in slow 
motion that it gives that impression. Total simulation time is only one 
second, in real time, it's fast. But the animation (using high-speed film 
;-) runs over four seconds, so it's super slo-mo. Bath oil beads should 
also deform somewhat on collision.

Then again, you may be referring to how high they bounce? The marbles 
have a very high coefficient of restitution, the floor, a medium one. I 
think also, because they "crumble" together, their drop isn't so sudden.

Then again, I know little about simulating real life, it could definitely 
be all wrong.

Well until someone can get marbles to balance in a cube formation, we'll never
know...

LOL, yeah, only a computer can line up marbles with such precision.
