## Definition

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

This traits class handles any type of 3D 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, 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, this class is also a model of AABBRayIntersectionTraits.
