基于MapX二次开发生成Delaunay三角网

The creation of delaunay triangulation network based on second Development of MapX

Delaunay三角网作为诸多不规则三角网中结构最优的三角网,被广泛应用于GIS、地学分析、有限元分析等领域。基于三角形生长算法,提出了一种适合于在MapX二次开发环境下生成Delaunay三角网的数据组织方法并给出程序。实现流程及实例,证明了该数据组织方法的可行性,为Delaunay三角网在基于MapX的二次开发应用和研究提供了有益的参考。

As a kind of the most excellent irregular triangulation network (ITN ), Delaunay triangulation network (D-ITN) is widely used in the fields of GIS, geography analysis and finite element analysis ect. In this paper, a kind of data structure is presented to generate D-ITN in the second development environment of MapX based on triangle generation algorithm, and the program process and an example are given. It has proved the feasibility of this data structure, which provides a useful reference mode for the application and research of D-ITN based on MapX.
