PolyhedronItems_3::Face Concept Reference

Definition

The PolyhedronItems_3::Face concept refines the HalfedgeDSItems::Face concept. This concept adds the requirement for the support of the geometry.

Refines:

HalfedgeDSItems::Face

Types in PolyhedronItems_3::Vertex_wrapper<Refs,Traits>::Face
Types for (optionally) associated geometry in faces. If it is not supported the respective type has to be defined, although it can be an arbitrary dummy type, such as void* or Tag_false.
typedef unspecified_type	Plane
	plane type stored in faces. More...
typedef unspecified_type	Supports_face_plane
	either CGAL::Tag_true or CGAL::Tag_false.

Only required when Supports_face_plane == Tag_true
Plane &	plane ()
const Plane &	plane () const

Plane

typedef unspecified_type PolyhedronItems_3::Face::Plane

plane type stored in faces.

A HalfedgeDS has no dimension, so this type is named Plane and not Plane_3.
