tricurv.tar
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.

This code makes use of routines: buildInverseTriangualtion.m & removeDO.m
