squared_radius ( Point_2<Kernel> p, Point_2<Kernel> q, Point_2<Kernel> r)

compute the squared radius of the circle passing through the points

q, and

Precondition:

q, and

r are not collinear.

squared_radius ( Point_2<Kernel> p, Point_2<Kernel> q)

compute the squared radius of the smallest circle passing through

p, and

q, i.e. one fourth of the squared distance between

p and

squared_radius ( Point_3<Kernel> p, Point_3<Kernel> q, Point_3<Kernel> r, Point_3<Kernel> s)

compute the squared radius of the sphere passing through the points

r and

Precondition:

r and

s are not coplanar.

squared_radius ( Point_3<Kernel> p, Point_3<Kernel> q, Point_3<Kernel> r)

compute the squared radius of the sphere passing through the points

q, and

r and whose center is in the same plane as those three points.

squared_radius ( Point_3<Kernel> p, Point_3<Kernel> q)

compute the squared radius of the smallest circle passing through

p, and

q, i.e. one fourth of the squared distance between

p and
