| Abstract: | According to the complexity problem of the collision detection of virtual plant visualization simulation,the paper put forward the key point’s save and access method.This method first analyzed the plant growth characteristics,then extracted and compared the biological point of the virtual plant.After that,these key points were stored by adjacency list,and used by depth-first traversal algorithm.This method could decrease the comparative quantity and improve the collision detection speed. |
