| 摘 要： | 城市管网是城市建设的重要组成部分。本文讨论了基于OpenGL的大规模城市管网三维建模技术,从介绍世界坐标系和局部坐标系的转换关系出发,重点介绍了管网的直线部分建模和管网衔接处的建模,提出了一种基于顶点混合技术来绘制管网衔接处的新算法,该算法方便高效,能产生逼真的效果,并给出了加快三维显示速度的方法,实现了城市管网的大规模实时建模。

| Abstract: | Pipeline is an important part of urban constructions. In this paper, 3D modeling of urban pipelines based on OpenGL is studied. Beginning with the relationship between the world coordinate system and the local coordinate system, the modeling of beeline and crack parts are emphatically described. A novel algorithm for modeling of pipeline cracks based on vertex blending technology has been proposed. Experimental results have shown the effectiveness of the proposal scheme. Pipeline is modeled livingly, which can speed up the 3D display at the same time, then large-scale of urban pipelines can be modeled in real-time. |
