WebAn algorithm for quality Delaunay meshing of 2D domains with curved boundaries is presented. The algorithm uses Ruppert’s “corner lopping” heuristic [MR96b:65137]. In addition to admitting a simple termination proof, the algorithm can accept curved input without any bound on the tangent angle between adjoining curves. WebPolyhedral meshes are increasingly becoming an attractive option with particular advantages over traditional meshes for certain applications. What has been missing is a robust polyhedral meshing algorithm that can handle broad classes of domains
