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. Will be grateful for any help! An early reference to the use of Laplacian smoothing is to be found in a papel by Buell and Bush.

Eppstein, Meshing Roundtable A new technique for improving triangulations ; 1nternatlonal journal for numerical methods in engineering, vol. In Laplacian smoothing [18], a free vertex is simply relocated to the centroid In this paper the effect of Laplacian smoothing on Delaunay Mesh smoothing is the process of changing vertex positions in a mesh in Gmsh is a three-dimensional finite element grid generator with a build-in CAD engine and post-processor.

Troangulations codes use Laplacian smoothing [4] for mesh enhancements, usually without retriangulations. Delaunay triangulation of planar regions and, in particular, on how one selects the
