OK, I've been reading up the on the process of rigging, and I was wondering what, fundamentally, bones and such are. I understand that they are the foundations of animations, i.e. they determine how parts of the model move, bend, and rotate. But what are the bones themsevles? I.E. how are they...
Source doesn't use NURBS modelling, but the splines I was referring to are (by my own induction, which is probably wrong) used by 3-D design packages to gauge animations and such.
I was reading a short paper on the principles and general techniques of animation, and it mentioned two types of splines and the differences between them. Realizing that it was old, but also realizing that I'd never heard of Catmull-Rom splines, I was wondering if they had become outmoded, or...
