CGAL 5.1.2 - 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.
CGAL::Polyhedron_traits_3<Kernel>
CGAL::Polyhedron_traits_with_normals_3<Kernel>
All models of the CGAL::Kernel
concept, e.g., CGAL::Simple_cartesian<FieldNumberType>
CGAL::Polyhedron_3<Traits>

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).
