CGAL 6.0 - 3D Polyhedral Surface
|
Required types and member functions for the PolyhedronTraits_3 concept. This geometric traits concept is used in the polyhedral surface data structure CGAL::Polyhedron_3<Traits>. Any CGAL kernel is a model of this concept and can be used directly as template argument.
CopyConstructible Assignable Kernel concept, e.g. CGAL::Simple_cartesian<FieldNumberType> CGAL::Polyhedron_traits_3<Kernel> CGAL::Polyhedron_traits_with_normals_3<Kernel> CGAL::Polyhedron_3<Traits> Types | |
| typedef unspecified_type | Point_3 |
| point type. | |
| typedef unspecified_type | Plane_3 |
| plane equation. | |
| typedef unspecified_type | Construct_opposite_plane_3 |
| is an unary function object that reverses the plane orientation. | |
Creation | |

| PolyhedronTraits_3 & | operator= (const PolyhedronTraits_3 &traits2) |
| assignment. | |
Operations | |
| Construct_opposite_plane_3 | construct_opposite_plane_3_object () |
| returns an instance of this function object. | |
is an unary function object that reverses the plane orientation.
Must provide Plane_3 operator()(Plane_3 plane) that returns the reversed plane. Required only if plane equations are supported and the inside_out() method is used to reverse the polyhedral surface orientation.
plane equation.
Even if plane equations are not supported with a particular polyhedral surface this type has to be defined (some dummy type).
