Hello all, Does anyone know where I might be able to find a (free) library that can estimate the curvature tensor on the vertices of a triangular mesh. I'd like to avoid something as complicated as CGAL if at all possible. I can find a ton of literature describing different method... but as is too often the case in graphics... no code. Any help would be greatly appreciated. Cheers, Rob

Check out trimesh2. It's GPL, and does a bunch of useful mesh operations including curvature estimation.
