## Member Function Documentation

template<class Mesh >

size_t OpenMesh::Decimater::MixedDecimaterT< Mesh >::decimate | ( | const size_t | _n_collapses,
|  | const float | _mc_factor
| ) |  |

Decimate (perform _n_collapses collapses).

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

template<class Mesh >

size_t OpenMesh::Decimater::MixedDecimaterT< Mesh >::decimate_to_faces | ( | const size_t | _n_vertices = `0`,
|  | const size_t | _n_faces = `0`,
|  | const float | _mc_factor = `0.8`
| ) |  |

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.
