## Member Function Documentation

## initialize()

template<class Mesh>

bool OpenMesh::Decimater::BaseDecimaterT< Mesh >::initialize | ( |  | ) |

Initialize decimater and decimating modules.

Return values: true ok false No ore more than one non-binary module exist. In that case the decimater is uninitialized!

## is_collapse_legal()

template<class Mesh>

bool OpenMesh::Decimater::BaseDecimaterT< Mesh >::is_collapse_legal | ( | const CollapseInfo & | _ci | ) |

protected

Is an edge collapse legal?

Performs topological test only. The method evaluates the status bit Locked, Deleted, and Feature.

Attention
  The method temporarily sets the bit Tagged. After usage the bit will be disabled!

## reset()

template<typename MeshT>

void OpenMesh::Decimater::BaseDecimaterT< MeshT >::reset | ( |  | ) |

inline protected

Reset the status of this class.

You have to call initialize again!!

## set_error_tolerance_factor()

template<class Mesh>

void OpenMesh::Decimater::BaseDecimaterT< Mesh >::set_error_tolerance_factor | ( | double | _factor | ) |

protected

This provides a function that allows the setting of a percentage of the original constraint of the modules.

Note that some modules might re-initialize in their set_error_tolerance_factor function as necessary

Parameters

  _factor | has to be in the closed interval between 0.0 and 1.0

## set_observer()

template<typename MeshT>

void OpenMesh::Decimater::BaseDecimaterT< MeshT >::set_observer | ( | Observer * | _o | ) |

inline

Add observer.

You can set an observer which is used as a callback to check the decimators progress and to abort it if necessary.

Parameters

  _o | Observer to be used
