Curvature estimation. Scheme of the curvature estimation computation. The original mesh (black disks and links) is smoothed by a Laplacian operator to give a smoothed mesh (gray circles and links). The displacement vectors between both meshes are depicted with thick dotted arrows. The dot products between these vectors and the normal vectors of the original mesh (thin arrows) are calculated. The signs of the results are shown next to the original mesh vertices.
