Laplacian smoothing and Delaunay triangulations – Wiley Online Library ; to maintain a Delaunay triangulation measurably improves Laplacian smoothing. In contrast to most triangulation algorithms which implicitly assume that triangulation point locations are fixed, ‘Laplacian ‘ smoothing focuses on moving point locations to improve triangulation. Given two triangles sharing an edge, the Laplacian weight laplcian to the edge is: Algorithm for computing Delaunay triangulations [Sibson, Computer J.
Feature, Laplacian smoothing and Delaunay triangulations. It will become clear that constraining Laplacian smoothing to maintain a Delaunay triangulation measurably improves Laplacian smoothing. By applying the equipotential method with unit weights to arbitrary triangulations, the iterative solutions to the difference.
