## CGAL::circumcenter

Point_2<Kernel> circumcenter ( Point_2<Kernel> p, Point_2<Kernel> q)
compute the center of the smallest circle passing through the points p and q. Note: this is the same as CGAL::midpoint(p, q) but is provided for homogeneity.

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)
compute the center of the smallest sphere passing through the points p and q. Note: this is the same as CGAL::midpoint(p, q) but is provided for homogeneity.

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.
