CGAL 5.3.1  2D and 3D Linear Geometry Kernel

CGAL::do_intersect() (2D Circular Kernel)
CGAL::do_intersect() (3D Spherical Kernel)
CGAL::intersection()
See Chapter 2D and 3D Geometry Kernel for details on a linear kernel instantiation.
Functions  
bool  CGAL::do_intersect (Type1< Kernel > obj1, Type2< Kernel > obj2) 
checks whether obj1 and obj2 intersect. More...  
bool  CGAL::do_intersect (Plane_3< Kernel > obj1, Plane_3< Kernel > obj2, Plane_3< Kernel > obj3) 
checks whether obj1 , obj2 and obj3 intersect.  
#include <CGAL/intersections.h>
checks whether obj1
and obj2
intersect.
Two objects obj1
and obj2
intersect if there is a point p
that is part of both obj1
and obj2
. The intersection region of those two objects is defined as the set of all points p
that are part of both obj1
and obj2
. Note that for objects like triangles and polygons that enclose a bounded region, this region is part of the object.
The types Type1
and Type2
can be any of the following:
Point_2<Kernel>
Line_2<Kernel>
Ray_2<Kernel>
Segment_2<Kernel>
Triangle_2<Kernel>
Iso_rectangle_2<Kernel>
Also, Type1
and Type2
can be both of type
In threedimensional space, the types Type1
and Type2
can be any of the following:
