Operations
A model of this concept must provide:
Kernel::FT	operator() (const Kernel::Sphere_3 &s)
	returns the squared radius of s.
Kernel::FT	operator() (const Kernel::Circle_3 &c)
	returns the squared radius of c.
Kernel::FT	operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q, const Kernel::Point_3 &r, const Kernel::Point_3 &s)
	returns the squared radius of the sphere passing through p, q, r and s. More...
Kernel::FT	operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q, const Kernel::Point_3 &r)
	returns the squared radius of the sphere passing through p, q and r, and whose center is in the plane defined by these three points.
Kernel::FT	operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q)
	returns the squared radius of the smallest circle passing through p, and q, i.e. one fourth of the squared distance between p and q.
Kernel::FT	operator() (const Kernel::Point_3 &p)
	returns the squared radius of the smallest circle passing through p, i.e. \( 0\).
