摘要
文章阐述了如何利用计算几何中的凸壳问题来处理测量中的DEM建模问题并推导出了TIN的建立方法。同时列举了该方法在舰艇螺旋桨 3维模拟中的应用。
The paper describes how to dea l with the modelling of DEM in surveying by using the convex shell problem in th e calculation geometry.The method of building TIN is derived.At the sam time the applications of the method to the 3D analog for warship serews are provided.
