text: It is known that there exists a unique Delaunay triangulation for P, if P is a set of points in general position; that is, no three points are on the same line and no four are on the same circle, for a two-dimensional set of points, or no n + 1 points are on the same hyperplane and no n + 2 points are on the same hypersphere, for an n-dimensional set of points.
