CGAL::do_intersect() (2D Circular Kernel)

bool	CGAL::do_intersect (Type1< CircularKernel > obj1, Type2< CircularKernel > obj2)
	checks whether obj1 and obj2 intersect.

Function Documentation

do_intersect()

bool CGAL::do_intersect	(	Type1< CircularKernel >	obj1,
		Type2< CircularKernel >	obj2
	)

#include <CGAL/Circular_kernel_intersections.h>

checks whether obj1 and obj2 intersect.

See Chapter Chapter_2D_Circular_Geometry_Kernel for details on a circular kernel instantiation.

When using a circular 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_2 only the curve is considered.

Type1 and Type2 can be any of the following:

• Line_2<CircularKernel>
• Circle_2<CircularKernel>
• Line_arc_2<CircularKernel>
• Circular_arc_2<CircularKernel>

An example illustrating this is presented in Chapter Chapter_2D_Circular_Geometry_Kernel.
