Curvature meseaure as described in the paper: Robust principal curvatures on Multiple Scales, Yong-Liang Yang, Yu-Kun Lai, Shi-Min Hu Helmut Pottmann SGP 2004 If pointVSfaceInt==true the covariance is computed by montecarlo sampling on the mesh (faster) If pointVSfaceInt==false the covariance is computed by (analytic)integration over the surface (slower)

| static float vcg::tri::UpdateCurvature< MeshType >::ComputeSingleVertexCurvature | ( | VertexPointer | v, |
| bool | norm = true |
||
| ) | [inline, static] |
Update the mean and the gaussian curvature of a vertex.
The function uses the VF adiacency to walk around the vertex.

| static void vcg::tri::UpdateCurvature< MeshType >::MeanAndGaussian | ( | MeshType & | m | ) | [inline, static] |
Computes the discrete mean gaussian curvature.
The algorithm used is the one Desbrun et al. that is based on a discrete analysis of the angles of the faces around a vertex.
It requires FaceFace Adjacency;
