Does anyone know how to actually set up the Subdivision matrix S (local). I read that its rows are to represent the stencils being applied..however, it depends on how you define you points i.e., whether its vertex, edge pt, edge pt, edge pt, face pt, face pt, face pt. or vertex, face pt, edge pt.. etc.
I read Jos Stam's paper "exact evaluation of a Catmull Clark Surface" but I can't seem to understand. Anyone that has good literature or advice on this?
