After the paper sufficiently considered creation algorithmic of triangulated irregular network in time and space and analyzed three creation algorithms of tin - divide - conquer, triangulation growth, incremental insertion, the paper adopts to a new algorithm that takes advantages of divide - conquer and triangulation growth. it can create tin quickly. the paper also uses break lines, terrain feature lines, building borderlines to be restriction condition and creates triangulated irregular network based on restriction
綜合考慮不規則三角網生成演算法的時間和空間性能,分析了常用的三種tin生成演算法:分割-歸並法、三角網生長法和逐點插入法,筆者採用分割-歸並法與三角網生長法相結合的演算法,快速生成了tin ,並以斷裂線、地性線、建築物邊界為約束條件,最終生成具有約束的不規則三角網。
