) 
#include <CGAL/squared_distance_2.h>
computes the square of the Euclidean distance between two geometric objects.
For arbitrary geometric objects obj1
and obj2
the squared distance is defined as the minimal squared_distance(p1, p2)
, where p1
is a point of obj1
and p2
is a point of obj2
. Note that for objects that have an inside (a bounded region), this inside is part of the object. So, the squared distance from a point inside is zero, not the squared distance to the closest point on the boundary.
In 2D, the types Type1
and Type2
can be any of the following:
as well as any combination of Kernel::Point_2
and Kernel::Weighted_point_2
In 3D, the types Type1
and Type2
can be any of the following:
as well as the following combinations:
Point_3
/Triangle_3
Point_3
/Tetrahedron_3
Weighted_point_3
/Triangle_3

/Tetrahedron_3
