Abstract.Delaunay Triangulation is the core algorithm for mesh generation. By Delaunay Triangulator you can make a general method to visualize geometry surfaces, so does OpenCascade. The paper focus on the geometry surfaces visualization, include the surfaces with holes. ...
好的三角剖分一般满足下面4个要求(摘自Delaunay Mesh Generation) First, large angles (near 180◦ ) can cause large interpolation errors. In the finite element method, these errors induce a large discretization error—the difference between the computed approximation and the true solution of the PDE...
In this chapter, the generation of triangle meshes from points is illustrated via the Delaunay triangulation. Apart from Delaunay triangulation being the most common triangulation method, the aim is also to give an overview of the typical issues of point
Shewchuk. Triangle is a small C program and its Delaunay refinement algorithm for quality mesh generation is a hybrid one. It includes divide-and-conquer and incremental insertion algorithms and sweepline Delaunay triangulation algorithm. This paper is focused on the usage of the Triangle and ...
