◆ do_intersect()

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

#include <CGAL/intersections.h>

checks whether obj1 and obj2 intersect.

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 for objects like triangles and polygons that enclose a bounded region, this region is part of the object.

The types Type1 and Type2 can be any of the following:

Also, Type1 and Type2 can be both of type

In three-dimensional space, the types Type1 and Type2 can be any of the following:
