This software package creates subdivision matrices for generalized quadratic and cubic B-spline subdivision for subdivision surfaces as well as subdivision volumes. The subdivision matrices define refinement rules for arbitrary combinatorial structures. The matrices have a valid eigenstructure and a subdominant eigenvalue of 1/2.
