摘要
道路与地形整体模型的构建是实现道路三维可视化的关键。论文基于在约束delaunay三角网中插入点和约束边的理论,提出一种道路设计面模型的构建方法以及其与地形表面模型融为一体的整体模型构建方法,使得道路设计面模型和地表模型不仅表面上是整合在一起的,并且其内部关系也是统一的。对其原理、方法及程序实现进行了介绍。
The key to realize the 3d road visualization is to establish the road-terrain 3d model. Based on the theory of insertion points and constrained bound into CDT, this Paper presents methods of constructing the road design surface model and overall model of the topography model and road design surface model, making the two models not only the surface is integrated, but their internal relations is unified. In this paper, the principles, methods and procedures to achieve were introduced.
