Member Function Documentation

template<class Mesh >

size_t OpenMesh::Decimater::DecimaterT< Mesh >::decimate

(

size_t

_n_collapses = 0

)

Decimate (perform _n_collapses collapses). Return number of performed collapses. If _n_collapses is not given reduce as much as possible

Definition at line 156 of file DecimaterT.cc.

template<class Mesh >

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

Decimate to target complexity (vertices and faces). Stops when the number of vertices or the number of faces is reached. Returns number of performed collapses.
