#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.
