Detailed Description

template<class MeshType>
class vcg::tri::UpdateCurvature< MeshType >

Management, updating and computation of per-vertex and per-face normals.

This class is used to compute or update the normals that can be stored in the vertex or face component of a mesh.

Member Typedef Documentation

◆ MeshGridType

template<class MeshType >
typedef vcg::GridStaticPtr<FaceType, ScalarType > vcg::tri::UpdateCurvature< MeshType >::MeshGridType

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)

Member Function Documentation

◆ MeanAndGaussian()

template<class MeshType >
static void vcg::tri::UpdateCurvature< MeshType >::MeanAndGaussian ( MeshType & m)
inlinestatic

Computes the discrete gaussian curvature.

◆ PrincipalDirections()

template<class MeshType >
static void vcg::tri::UpdateCurvature< MeshType >::PrincipalDirections ( MeshType & m)
inlinestatic

Compute principal direction and magniuto of curvature.

◆ VertexCurvature()

template<class MeshType >
static float vcg::tri::UpdateCurvature< MeshType >::VertexCurvature ( VertexPointer v,
bool norm = true )
inlinestatic

Update the mean and the gaussian curvature of a vertex.

The function uses the VF adiacency to walk around the vertex.

Returns
It will return the voronoi area around the vertex. If (norm == true) the mean and the gaussian curvature are normalized. Based on the paper "Optimizing 3d triangulations using discrete curvature analysis"
