bqcurv

Calculates the curvature of a triangulated surface

Input:
Structure array [R] with the following fields:
R.points - Nx7 array of vertex coordinates: pt. no., x-value, y-value, z-value, norm_x, norm_y, norm_z.
norm_* are components of the unit normal of that vertex;
R.neighbours - Nx1 cell array listing the neighbours of each vertex. if no neighbour list is provided, <bqcurv.m> will calculate the neighbours using <find_neighbours.m>;
R.polygons - Mx7 array of triangles: poly. no., pt. #1, pt. #2, pt. #3, Nx, Ny, Nz.
N_* is the unit normal of that polygon;

Output
The fields R.kappa_min and R.kappa_max
