摘要 根据Voronoi单胞的定义,在已知Voronoi单胞顶点的前提下,利用Delaunay三角网将Voronoi单胞划分成若干四面体,通过求解四面体的体积得到Voronoi单胞的体积,最后应用算例验证了该方法的可行性。 According to the definition of the Vomnoi cell, we used the Delaunay triangulation to divide the Vomnoi cell into several tetrahedrons based on the Voronoi cell vertices, and obtained the volume of the Voronoi cell by calculating the volume of this tetrahedron. The results of a sample calculation verified the applicability of the algorithm.
