Summary
An incremental Delaunay triangulation algorithm to generate Voronoi diagrams within the L-infinity norm is presented. The main qualities are the preservation of the simplicity of the classical L2 version and its its intrinsic robustness It is then coupled to the well known Lloyd algorithm for computing Centroidal Voronoi Tesselations of point sets. This algorithm is then used to generate well shaped quadrilateral meshes.
