摘要
在地铁施工过程中,经常出现不同管道发生交叉碰撞的现象,导致工程上的大量返工,增加了建设成本。利用VRML(虚拟现实建模语言)对地铁管线进行三维建模,然后结合碰撞检测算法,设计出地铁管线三维建模与碰撞分析软件系统。该系统首先将地铁二维图纸进行三维建模,然后通过基于包围盒的碰撞检测算法,分析出存在交叉碰撞的部分,并提供二维、三维的显示和详细的碰撞坐标,供设计人员修改图纸。
In subway engineering,there are many crossing collisions between different pipelines,which often led to large number of reworks and thus increased the cost.By using VRML（virtual reality modeling language）,a3 D model of subway pipelines is established,then combined with collision detection algorithm,the analytic software of 3D modeling and collision is designed.This system establishes a3 D model based on the 2D drawings for the first time,and based on the collision algorithm of bounding volume boxes to analyze the collision parts of subway pipelines,so as to provide 2D and 3D displays and detailed collision coordinates for the designers.
