Sorry, what I ment was that I can use a mesh2 object with normal smoothing
to approximate a SubD surface, but with Catmul-Rom the render engine would
actualy subdivide the mesh on the fly to provide smoothing.

I think this would be useful as I often see artifacts with normal smoothing
in animations, and especialy when a normal statement is included in the
texture.  A basic implimentation dosn't _seem_ that difficult.  I don't
know if your spline functions could be of any use for this, I just though I
recognized the name of the algorithm.
