Circumcircle: a unique circlethat passes through each of the triangles three vertices Delaunay Edges Voronoi Edges 11. VORONOI AND DELAUNAY TRIANGULATION For a set S of points in the Euclidean plane, the unique triangulation DT(S) of S such that no point in S is inside the circumcircle of any triangle in DT(S).The Voronoi grid is formed by the perpendicular-bisectors of the edges of the Delaunay triangles. alhad also shown that the kind of grid is able to reduce grid orientation effect (2004)ġ0.
