道路设计的三维可视化

实时三维交互式仿真技术是实现道路线路三维可视化设计的关键,本文应用约束Delaunay三角剖分原理建立道路三维整体模型,在此基础上,提出并实现了有效的道路三维模型的视相关简化方法,并结合真实感图形绘制技术开发了道路三维场景的实时动态浏览平台。最后将该平台与线路CAD系统集成,实现了线路设计过程和设计成果的可视化。

Three-Dimensional Visualization of Road Design

Real time three dimensional interactive imitating technology is the key for achieving three dimensional visualization design of road routes. The paper establishes road three dimensional integral model by the principle of restraining Delaunay delta section. On this base it puts forward and realizes the vision relative simplified method of road three dimensional model. It also develops the real time dynamic browsing platform of road three dimensional scene in combination with real sense figure drawing technology. At last, the platform will be integrated with CAD system to realize the route design course and the visualization of the design result.
