Parallel algorithm of Delaunay triangulation dividing for scattered point set based on Quad-Edge structure
摘要
Abstract
The triangulation dividing algorithm plays an important role in computational geometry,in which the efficiency and quality of triangular mesh are inseparably linked with the follow⁃up study. In this paper,the basic principle of Delaunay tri⁃angulation dividing algorithm is analyzed and the divide⁃and⁃conquer algorithm for scattered point set is investigated based on the Quad⁃Edge structure. The popular Map⁃Reduce parallel programming model is introduced to the Delaunay triangulation divid⁃ing algorithm when dealing with scattered point set. The experiment result shows the parallel triangulation dividing parallelization can improve the efficiency of this algorithm in the case of mass data by means of Map⁃Reduce Programming Model. Further⁃more,this method has good elastic capacity and the efficiency is obviously higher than another two methods,namely the divide⁃and⁃conquer algorithm based on the Quad⁃Edge structure and the Bowyer⁃Watson triangulation dividing algorithm with triangular index.关键词
