Member Function Documentation

◆ decimate()

template<class Mesh >
size_t OpenMesh::Decimater::McDecimaterT< Mesh >::decimate ( size_t  _n_collapses)

Decimate (perform _n_collapses collapses).

Return number of performed collapses. If _n_collapses is not given reduce as much as possible

◆ decimate_to_faces()

template<class Mesh >
size_t OpenMesh::Decimater::McDecimaterT< 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.
