摘要
TIN是由三角形构成的一种有限元网格,它主要用来表示地形或地物表面。本文从几种不同建TIN的算法(三角网生长算法、凸壳算法、前沿边推进算法和贪心算法)来比较和分析各算法的优缺点。
TIN is constituted by the triangle a finite element mesh, which is mainly used to express topography or terrain surface. This paper from several different TIN algorithm （ triangulation network growth algorithm, convex hull algorithm, front edge push algorithm and greedy algorithm ） to compare and analyze the advantages and shortcomings of different algorithms.
