CGAL::AABB_traits_2< GeomTraits, AABBPrimitive, BboxMap > Class Template Reference

#include <CGAL/AABB_traits_2.h>

Definition

template<typename GeomTraits, typename AABBPrimitive, typename BboxMap = Default>
class CGAL::AABB_traits_2< GeomTraits, AABBPrimitive, BboxMap >

This traits class handles any type of 2D geometric primitives provided that the proper intersection tests and constructions are implemented.

It handles points, rays, lines and segments as query types for intersection detection and computations, and it handles points as query type for distance queries.

Is model of

AABBTraits

AABBRayIntersectionTraits

Template Parameters

GeomTraits	must be a model of the concept AABBGeomTraits_2, and provide the geometric types as well as the intersection tests and computations.
Primitive	provide the type of primitives stored in the AABB_tree. It is a model of the concept AABBPrimitive or AABBPrimitiveWithSharedData.
BboxMap	must be a model of ReadablePropertyMap that has as key type a primitive id, and as value type a Bounding_box. If the type is Default the Datum must have the member function bbox() that returns the bounding box of the primitive.

If the argument GeomTraits is a model of the concept AABBRayIntersectionGeomTraits_2, this class is also a model of AABBRayIntersectionTraits.
