## 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.
