基于Three.js的地下管线三维建模可视化研究

Research on Visualization of 3D Modeling of Underground Pipelines Based on Three.js

围绕地下管线的三维建模可视化技术进行分析探讨,针对其跨平台性的不足提出一种基于Three.js的三维管线建模可视化方法。其主要思想是:将地下管线抽象成圆柱体,使用WebGL开源框架Three.js针对从后台获取到的二维管线矢量数据进行批量建模可视化。通过实验对研究方法进行了验证,在普通的浏览器渲染三维地下管线,摆脱了插件和本地应用程序的制约,实现了二维图形窗口与三维图形窗口在同一页面中的整合与交互。

The 3 d automatic modeling visualization of underground pipeline is analyzed and discussed,and to avoid shortages of crossing platform this paper proposes a three-dimension automated modeling method of underground pipeline based on Three.js. The main idea is： The underground pipes are abstracted into cylinders,using WebGL open source framework Three.js to execute automated batch modeling visualization for two-dimensional pipeline vector data obtained from the background. The research method was validated by experiment. Rendering three-dimensional underground pipeline in the ordinary browser,which can get rid of the plug-in and local application constraints. The experiment enables two-dimensional graphic window and three-dimensional graphic window to integrate and interactive in the same page.
