[Papervision3D] Procedurally generated models

[John Grden]

dood that's cool!  LOL, what a great idea

as for the materials thought - that's very interesting.  Jake was just
telling me how to some shade spoofing with 8 different versions of the xwing
map I did.  Based on rotation, one of the 8 would be used on the model.

My thought is, I like having the materials for an object stored WITH the
object
