New 3D engines in CS4?

I guess the new 3D functions in CS4 is more powerful than Papervision and others… so the question is, is it possible to make a new 3D engine that can import 3D models and such - only with the existing x,y,z,rotationX,rotationY,rotationZ? Would it be better than Papervision?

Maybe it’s already been done? :genius:
