Member Function Documentation

template<class Mesh >
bool OpenMesh::Decimater::BaseDecimaterT< Mesh >::initialize ( void  )

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!

Definition at line 243 of file BaseDecimaterT.cc.

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!

Definition at line 107 of file BaseDecimaterT.cc.

template<typename MeshT >
void OpenMesh::Decimater::BaseDecimaterT< MeshT >::reset ( )
inlineprotected

Reset the status of this class

You have to call initialize again!!

Definition at line 253 of file BaseDecimaterT.hh.

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
_factorhas to be in the closed interval between 0.0 and 1.0

Definition at line 198 of file BaseDecimaterT.cc.

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
_oObserver to be used
