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.
