Definition

The concept FaceListGraph refines the concept FaceGraph and adds the requirement for traversal of all faces in a graph.

Associated Types
boost::graph_traits<FaceListGraph>::face_iterator

A face iterator (obtained via faces(g)) provides access to all of the faces in a graph. A face iterator type must meet the requirements of MultiPassInputIterator. The value type of the face iterator must be the same as the face descriptor of the graph.

◆ faces()

template<typename FaceListGraph >
std::pair< boost::graph_traits< FaceListGraph >::face_iterator, boost::graph_traits< FaceListGraph >::face_iterator > faces ( const FaceListGraph &  g)
related

returns an iterator range over all faces.

Examples:
BGL_polyhedron_3/copy_polyhedron.cpp, BGL_polyhedron_3/normals.cpp, BGL_surface_mesh/seam_mesh.cpp, and Polygon_mesh_processing/face_filtered_graph_example.cpp.

◆ num_faces()

template<typename FaceListGraph >
boost::graph_traits< FaceListGraph >::face_size_type num_faces ( const FaceListGraph &  g)
related

returns an upper bound of the number of faces of the graph.

Attention
num_faces() may return a number larger than std::distance(faces(g).first, faces(g).second). This is the case for implementations only marking faces deleted in the face container.
