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>. This concept is a subset of the 3d kernel traits and any Cgal kernel model can be used directly as template argument.
CopyConstructable, Assignable.
| PolyhedronTraits_3::Point_3 | |
|
point type.
| |
| PolyhedronTraits_3::Plane_3 | |
|
plane equation. Even if plane equations
are not supported with a particular polyhedral surface this
type has to be defined (some dummy type).
| |
| PolyhedronTraits_3::Construct_opposite_plane_3 | |
|
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.
| |
| PolyhedronTraits_3 traits ( traits2); | |
|
copy constructor.
| |
| PolyhedronTraits_3& | traits = traits2 | assignment. |
| Construct_opposite_plane_3 | traits.construct_opposite_plane_3_object () | |
| returns an instance of this function object. | ||
