◆ 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:

An example illustrating this is presented in Chapter Chapter_2D_Circular_Geometry_Kernel.
