CGAL 5.5  2D and 3D Linear Geometry Kernel

bool  CGAL::do_intersect (Type1< SphericalKernel > obj1, Type2< SphericalKernel > obj2) 
checks whether obj1 and obj2 intersect. More...  
bool  CGAL::do_intersect (Type1< SphericalKernel > obj1, Type2< SphericalKernel > obj2, Type3< SphericalKernel > obj3) 
checks whether obj1 , obj2 and obj3 intersect. More...  
bool CGAL::do_intersect  (  Type1< SphericalKernel >  obj1, 
Type2< SphericalKernel >  obj2  
) 
#include <CGAL/Spherical_kernel_intersections.h>
checks whether obj1
and obj2
intersect.
See Chapter Chapter_3D_Spherical_Geometry_Kernel for details on a spherical kernel instantiation.
When using a spherical kernel, in addition to the function overloads documented here, the following function overloads are also available.
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 while for a polygon we consider the enclosed domain, for an object of type Circle_3
or Sphere_3
only the curve or the surface is considered.
Type1
and Type2
can be any of the following:
Line_3<SphericalKernel>
Circle_3<SphericalKernel>
Plane_3<SphericalKernel>
Sphere_3<SphericalKernel>
Line_arc_3<SphericalKernel>
Circular_arc_3<SphericalKernel>
An example illustrating this is presented in Chapter Chapter_3D_Spherical_Geometry_Kernel.
bool CGAL::do_intersect  (  Type1< SphericalKernel >  obj1, 
Type2< SphericalKernel >  obj2,  
Type3< SphericalKernel >  obj3  
) 
#include <CGAL/Spherical_kernel_intersections.h>
checks whether obj1
, obj2
and obj3
intersect.
Type1
, Type2
and Type3
can be:
