Smooth Triangulated Mesh

Accurate smoothing of triangulated patch / mesh

This function smooths a triangulated Mesh / Patch.

Supports accurate curvature flow smoothing. Which smooths in the direction of the normal keeping the edge ratio's the same.
Also supports Laplacian smoothing with inverse vertice-distance based umbrella weights, making the edge lengths more uniform.

Can be used to smooth iso-surface meshes, for scale space and simplification of patches.

Code:
The code is written in Matlab and partly in c-code for speed up reasons.
