CGAL 6.0 - 3D Polyhedral Surface
|
The PolyhedronItems_3::Face concept refines the HalfedgeDSItems::Face concept. This concept adds the requirement for the support of the geometry.
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 | |
| typedef unspecified_type | Plane |
| plane type stored in faces. | |
| 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 type stored in faces.
A HalfedgeDS has no dimension, so this type is named Plane and not Plane_3.
