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.

◆ 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
_errMaximum error allowed
_binaryLet the module work in non-binary mode in spite of the enabled constraint.
