| Fast Delaunay Triangulation for Converging Point Relocation Sequences (2009) | |||||||||||||||
Abstract | |||||||||||||||
| This paper considers the problem of updating efficiently a Delaunay triangulation when vertices are moving under small perturbations. Its main contribution is a set of algorithms based on the concept of vertex tolerance. Experiments show that it is able to outperform the naive rebuilding algorithm in certain conditions. For instance, when points, in two dimensions, are relocated by Lloyd's iterations, our algorithm performs several times faster than rebuilding. | |||||||||||||||
