| The PolyhedronItems_3 concept refines the HalfedgeDSItems concept. In addition to the requirements stated there, a model for this concept must fulfill the following requirements for the local PolyhedronItems_3::Vertex_wrapper<Refs,Traits>::Vertex type and PolyhedronItems_3::Face_wrapper<Refs,Traits>::Face type in order to support the point for vertices and the optional plane equation for facets. Note that the items class uses face instead of facet. Only the polyhedral surface renames faces to facets. More...
