摘要
针对道路或地形数据量大,动画可能产生停顿、空洞等失真现象,文章介绍了用OpenGL技术实现沿路线分段显示,进行动画处理的方法,以期得到良好的视觉效果。通过编程验证,证明了这种处理技术的可行性。文章还给出了部分Delphi编程的源代码。
OpenCL technique is one of the main methods for creating the real-time road animation. In this paper, the basic conceptions of Digital Terrain Model and 3D Highway Modeling are introduced. And the methods of making 3D road animation are also presented. Then,aiming at the phenomena of halts,interspaces and so on, the paper works out the staged display technology to get better visual effect when data are tremendous. It proves the feasibility and rationality by programming. At last, some source codes are given by using Delphi.
