CGAL 5.3  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 Kernel
concept, e.g., CGAL::Simple_cartesian<FieldNumberType>
CGAL::Polyhedron_3<Traits>
Types  
typedef unspecified_type  Point_3 
point type.  
typedef unspecified_type  Plane_3 
plane equation. More...  
typedef unspecified_type  Construct_opposite_plane_3 
is an unary function object that reverses the plane orientation. More...  
Creation  
PolyhedronTraits_3 (const PolyhedronTraits_3 &traits2)  
copy constructor.  
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).
