摘要
管线是主要的城市基础设施之一,管线三维建模与可视化是构建"数字城市"的重要内容。采用断面与体面三角剖分拟合方法构建弯曲管线、三连通管线的三维模型,给出建模的方法和步骤,以OpenGL作为三维图形应用程序接口,实现管线三维建模及可视化。
Pipeline is one of the main urban infrastructures. important contents to build a ＂digital city＂. In this paper, 3D modeling and visualization of pipelines are 3D models of bending pipeline and triconnected pipeline are reconstructed by the method of section and surface triangulation fitting, and modeling method and steps were presented. Based on 3D graphics adapter OpenGL, 3D modeling and visualization of pipelines have realized.
