摘要
3维管线建模与可视化是构建数字城市及实现管线管理信息系统中不可缺少的重要组成部分。本文介绍了利用初始点集构造管线衔接处3维模型的基本步骤,着重对OpenGL 3维管线复杂衔接处3维建模的关键问题进行了探讨。最后用实验对本文提出的理论进行了验证。实验表明,利用简单3维几何变换及基准面旋转的方法可以高效便捷地实现各种复杂管线衔接处的3维可视化,并在实际运用中取得了较好的效果。
3-D modeling and visualization of pipeline is an indispensable and important component that eonstructed Digital City and implementation of pipeline Management Information System. This paper describes the basic steps that eonstrueted 3-D pipeline eonneetion by using the initial points, and espeeially discusses the key issues of constructed the 3-D pipeline complexity connection using OpenGL. At last, the author proved the theory mentioned in this article by experiment, it shows that 3-D geometrie transformation and datum plane rotation can realize the visualization of 3-D pipeline eomplexity connection efficiently and conveniently, and this technology have aebieved good effect in the practical application.
