Research and Application of Collision Detection on Steel Structure in Virtual Pre-Assembly Environment

In order to detect the possible collision of steel structural in virtual pre-assembly environment, a collision detection program based on the bounding box algorithm and the spatial triangle intersection detection algorithm was developed. And the feasibility and effectiveness of the collision detection program in virtual pre-assembly were verified by an example. The results showed that: according to this method, the collision detection in virtual pre-assembly has good feasibility and is suitable to practical projects.
