【摘要】 介绍了TIN进行面模型构造的方法,对面模型构造过程中的三角剖分和模型优化问题进行了分析。以广泛采用的Delaunay三角网为例,设计了三维曲面模型的构造方法,并基于C++结合OPENGL开发了三维曲面构造软件。最终将软件应用于三维地形构造,对丘陵山地和盆地或高原边缘进行了模型构造,取得了较好的构造效果。更多还原

【Abstract】 The method of surface model construction of TIN is introduced,and the triangulation and model optimization problems in the construction process of the opposite model are analyzed. Taking the widely used Delaunay triangulation network as an example,the construction method of 3 D surface model is designed,and the 3 D surface construction software is developed based on the combination of C + + and OPENGL. Finally,the software is applied to the three-dimensional topographic structure,and the model structure of the hilly and plateau edges is constructed,and a better structural effect has been obtained.更多还原
