Currently we have two methods for computing curvature in our library: http://vcg.cvs.sourceforge.net/vcg/vcg/vcg/complex/trimesh/update/curvature.h they have been recentely cleaned up by Fabio Ganovelli are based on the methods proposed in Discrete Differential-Geometry Operators for Triangulated 2-Manifolds Mark Meyer, Mathieu Desbrun, Peter Schroder, Alan H. Barr VisMath '02, Berlin and in Compute principal direction and magniuto of curvature as describe in the paper: @InProceedings{bb33922, author = "G. Taubin", title = "Estimating the Tensor of Curvature of a Surface from a Polyhedral Approximation", booktitle = "International Conference on Computer Vision", year = "1995", P.
