SurfaceMeshTraits_3

Definition

The concept SurfaceMeshTraits_3 describes the knowledge that is required on the surface to be meshed. A model of this concept implements an oracle that is able to tell whether a segment (or a ray, or a line) intersects the surface or not and to compute some intersection points if any. The concept SurfaceMeshTraits_3 also includes a constructor able to provide a small set of initial points on the surface.

Types

SurfaceMeshTraits_3::Point_3
	The type of points. This type is required to match the point type of the three dimensional embedding triangulation C2T3::Triangulation_3.
SurfaceMeshTraits_3::Segment_3
	The type of segments.
SurfaceMeshTraits_3::Ray_3
	The type of rays.
SurfaceMeshTraits_3::Line_3
	The type of lines.
SurfaceMeshTraits_3::Surface_3
	The surface type.

SurfaceMeshTraits_3::Intersect_3
	A model of this type provides the operator CGAL::object operator()(Surface_3 surface, Type1 type1) to compute the intersection of the surface with an object of type Type1 which may be Segment_3, Ray_3 or Line_3 .

SurfaceMeshTraits_3::Construct_initial_points
	A model of this type provides the following operators to construct initial points on the surface: template <class OutputIteratorPoints> OutputIteratorPoints operator()(OutputIteratorPoints pts) which outputs a set of points on the surface, template <class OutputIteratorPoints> OutputIteratorPoints operator() (OutputIteratorPoints pts, int n) which outputs a set of n points on the surface.

Operations

The following functions give access to the construction objects:

Intersect_3	traits.intersect_3_object ()
Construct_initial_points	traits.construct_initial_points_object ()
