Integrated pipeline soft-collision algorithm for car depot of Urban Transit
-
摘要: 本软碰撞算法在MicroStation平台下实现,首先判断管线的空间位置关系,将空间管线抽象为圆柱体,针对平行管线或垂直管线及其他非平行和非垂直管线间距采用不同算法分别计算管线间最短距离,经测试该算法满足设计规范平行或垂直不同要求,使无差设计成为可能。

Abstract: The soft collision algorithm was implemented on MicroStation platform to determine the pipeline’s spatial relationship. Spatial pipeline was abstracted as cylinder, in view of the parallel or vertical piping as well as other non-parallel and non-vertical line spacing, different algorithms were used to calculate the shortest distance of pipeline. The Algorithm could meet the different requirements of design specification for parallel or vertical.-
