## 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

## ◆ collapse_priority()

template<class MeshT >

float OpenMesh::Decimater::ModHausdorffT< MeshT >::collapse_priority | ( | const CollapseInfo & | _ci | ) |
| override 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
