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!

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

Reset the status of this class.

You have to call initialize again!!

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
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
