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
