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 )

virtual

compute Hausdorff error for one-ring

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

Parameters

_ci	Collapse info data

Returns

Binary return, if collapse is legal or illegal

Reimplemented from OpenMesh::Decimater::ModBaseT< MeshT >.
