Constrained delaunay tessellation

WebDescription. voronoi (x,y) plots the bounded cells of the Voronoi diagram for the 2-D points in vectors x and y. voronoi (x,y,T) uses the Delaunay triangulation T to plot the Voronoi diagram. voronoi (TO) uses the delaunayTriangulation object TO to plot the Voronoi diagram. [vx,vy] = voronoi ( ___) returns the 2-D vertices of the Voronoi edges.

WebDec 1, 2009 · I need to find the Delaunay tessellation of a polygon in Python, and the only libraries I could find (Delny, scikits) triangulate point clouds, not polygons. Any suggestions? ... A polygon does not necessarily have a Delaunay triangulation. You need constrained Delaunay. – sje397. Dec 11, 2010 at 14:39. WebA new algorithm is presented that uses a local transformation procedure to construct a triangulation of a set of n three-dimensional points that is pseudo-locally optimal with respect to the sphere criterion. It is conjectured that this algorithm always constructs a Delaunay triangulation, and this conjecture is supported with experimental results. The empirical …

Web2. TESSELLATION OF SPACE The atomic strain requires a precise way to divide the volume allotted to an atom and an unambiguous way to identify the interstices in a system. The Voronoi and Delaunay tessellation are methods that meet this requirement. Our development builds on the work of Tanemura et al. [1983]. WebTriangle generates exact Delaunay triangulations, constrained Delaunay triangulations, conforming Delaunay triangulations, Voronoi diagrams, and high-quality triangular meshes. The latter can be generated with no small or large angles, and are thus suitable for finite element analysis.
