CGAL::circumcenter

Point_2<Kernel>
circumcenter ( Point_2<Kernel> p,
Point_2<Kernel> q,
Point_2<Kernel> r)
compute the center of the circle passing through the points p, q, and r.
Precondition: p, q, and r are not collinear.

Point_2<Kernel> circumcenter ( Triangle_2<Kernel> t)
compute the center of the circle passing through the vertices of t.
Precondition: t is not degenerate.

Point_3<Kernel>
circumcenter ( Point_3<Kernel> p,
Point_3<Kernel> q,
Point_3<Kernel> r)
compute the center of the circle passing through the points p, q, and r.
Precondition: p, q, and r are not collinear.

Point_3<Kernel> circumcenter ( Triangle_3<Kernel> t)
compute the center of the circle passing through the vertices of t.
Precondition: t is not degenerate.

Point_3<Kernel>
circumcenter ( Point_3<Kernel> p,
Point_3<Kernel> q,
Point_3<Kernel> r,
Point_3<Kernel> s)
compute the center of the sphere passing through the points p, q, r, and s.
Precondition: p, q, r, and s are not coplanar.

Point_3<Kernel> circumcenter ( Tetrahedron_3<Kernel> t)
compute the center of the sphere passing through the vertices of t.
Precondition: t is not degenerate.
