Curvature calculations on triangular 3D surface

05 Aug 2009 (Updated 06 Aug 2009)

Calculate principal curvatures on a triangular mesh in 3D.

File Information
Description	Function to calculate the principal curvatures on a triangular mesh. Approximations of curvature are based on local (N=1) neighborhood elements and vertices. Note: Directions of curvatures aren't calculated appropriately. Will post an updated version once this is implemented. Note that calculations at vertices with few adjacent triangles, and hence few adjacent vertices, are expanded to a greater neighborhood.
