## Detailed Description

### template<class MeshT>
class OpenMesh::Decimater::ModQuadricT< MeshT >

Mesh decimation module computing collapse priority based on error quadrics.

This module can be used as a binary and non-binary module.

## Constructor & Destructor Documentation

template<class MeshT>

OpenMesh::Decimater::ModQuadricT< MeshT >::ModQuadricT | ( | MeshT & | _mesh | ) |
| inline

Constructor.

## Member Function Documentation

template<class MeshT>

virtual float OpenMesh::Decimater::ModQuadricT< MeshT >::collapse_priority | ( | const CollapseInfo & | _ci | ) |
| inline virtual

Compute collapse priority based on error quadrics.

See Also
  ModBaseT::collapse_priority() for return values
  set_max_err()

template<class MeshT>

void OpenMesh::Decimater::ModQuadricT< MeshT >::set_max_err | ( | double | _err,
|  | bool | _binary = `true`
| ) |  |
| inline

Set maximum quadric error constraint and enable binary mode.

Parameters

  _err | Maximum error allowed
  _binary | Let the module work in non-binary mode in spite of the enabled constraint.
