Member Function Documentation

template<class Mesh >

size_t OpenMesh::Decimater::DecimaterT< Mesh >::decimate ( size_t _n_collapses = 0 )

Perform a number of collapses on the mesh.

Parameters

_n_collapses Desired number of collapses. If zero (default), attempt to do as many collapses as possible.

Note: This operation only marks the removed mesh elements for deletion. In order to actually remove the decimated elements from the mesh, a subsequent call to ArrayKernel::garbage_collection() is required.

template<typename MeshT >

size_t OpenMesh::Decimater::DecimaterT< MeshT >::decimate_to ( size_t _n_vertices )

inline

Decimate the mesh to a desired target vertex complexity.

Parameters

_n_vertices Target complexity, i.e. desired number of remaining vertices after decimation.

Note: This operation only marks the removed mesh elements for deletion. In order to actually remove the decimated elements from the mesh, a subsequent call to ArrayKernel::garbage_collection() is required.

template<class Mesh >

size_t OpenMesh::Decimater::DecimaterT< Mesh >::decimate_to_faces	(	size_t	_n_vertices = `0`,
		size_t	_n_faces = `0`
	)

Attempts to decimate the mesh until a desired vertex or face complexity is achieved.

Parameters

_n_vertices	Target vertex complexity.
_n_faces	Target face complexity.

Note: Decimation stops as soon as either one of the two complexity bounds is satisfied.; This operation only marks the removed mesh elements for deletion. In order to actually remove the decimated elements from the mesh, a subsequent call to ArrayKernel::garbage_collection() is required.
