DelaunayTriangulationQ

DelaunayTriangulationQ[{{x1, y1}, {x2, y2}, ...}, val]
gives True if the triangulation of the points {{x1, y1}, ...} represented by the vertex adjacency list val is a Delaunay triangulation and False otherwise.
DelaunayTriangulationQ[{{x1, y1}, {x2, y2}, ...}, val, hull]
takes hull to be the convex hull index list.
  • The convex hull index list hull and the elements of the vertex adjacency list val must both list vertices in counterclockwise order.
