Member Function Documentation

◆ decimate()

template<class Mesh >

size_t OpenMesh::Decimater::DecimaterT< Mesh >::decimate	(	size_t	_n_collapses = `0`,
		bool	_only_selected = `false`
	)

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.
_only_selected	Only consider vertices which are selected for decimation

Returns: Number of collapses that were actually performed.

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.

Definition at line 150 of file DecimaterT_impl.hh.

◆ decimate_to()

template<typename MeshT >

size_t OpenMesh::Decimater::DecimaterT< MeshT >::decimate_to	(	size_t	_n_vertices,
		bool	_only_selected = `false`
	)

inline

Decimate the mesh to a desired target vertex complexity.

Parameters

_n_vertices	Target complexity, i.e. desired number of remaining vertices after decimation.
_only_selected	Only consider vertices which are selected for decimation

Returns: Number of collapses that were actually performed.

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.

Definition at line 121 of file DecimaterT.hh.

◆ decimate_to_faces()

template<class Mesh >

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

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.
_only_selected	Only consider vertices which are selected for decimation

Returns: Number of collapses that were actually performed.

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.

◆ heap_vertex()

template<class Mesh >
