Abstract | dc.description.abstract | We introduce a new Lepp-Delaunay algorithm for quality
triangulation. For every bad triangle t with smallest angle less than a
threshold angle θ, a Lepp-search is used to find an associated convex terminal
quadrilateral formed by the union of two terminal triangles which
share a local longest edge (terminal edge) in the mesh. The centroid of
this terminal quad is computed and Delaunay inserted in the mesh. The
algorithm improves the behavior of a previous Lepp-Delaunay terminal
edge midpoint algorithm. The centroid method computes significantly
smaller triangulation than the terminal edge midpoint variant, produces
globally better triangulations, and terminates for higher threshold angle
θ (up to 36◦). We present geometrical results which explain the better
performance of the centroid method. Also the centroid method behaves
better than the off-center algorithm for θ bigger than 25◦. | en_US |
