Detailed Description

template<class MeshT>
class OpenMesh::Decimater::ModHausdorffT< MeshT >

Use Hausdorff distance to control decimation.

This module computes the aspect ratio.

In binary mode, the collapse is legal if:

  • The distance after the collapse is lower than the given tolerance

No continuous mode

Member Function Documentation

template<class MeshT >
float OpenMesh::Decimater::ModHausdorffT< MeshT >::collapse_priority ( const CollapseInfo _ci)

compute Hausdorff error for one-ring

This mod only allows collapses if the Hausdorff distance after a collapse is lower than the given tolerance.

_ciCollapse info data
Binary return, if collapse is legal or illegal
