| bool | CGAL::do_intersect (Type1< SphericalKernel > obj1, Type2< SphericalKernel > obj2) |
checks whether obj1 and obj2 intersect. | |
| bool | CGAL::do_intersect (Type1< SphericalKernel > obj1, Type2< SphericalKernel > obj2, Type3< SphericalKernel > obj3) |
checks whether obj1, obj2 and obj3 intersect. | |
| bool CGAL::do_intersect | ( | Type1< SphericalKernel > | obj1, |

#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.
