CGAL::Polyhedron_items_with_id_3

Definition

The class Polyhedron_items_with_id_3 is a model of the PolyhedronItems_3 concept. It provides definitions for vertices with points, halfedges, and faces with plane equations, all of them with an additional integer field which can be used to index the items in a Bgl algorithm. The polyhedron traits class must provide the respective types for the point and the plane equation. Vertices and facets both contain a halfedge handle to an incident halfedge.
