Fast Image Interaction Technology Based on Virtual Reality

Collision detection is mainly used to determine whether two (or more) objects intersect in the virtual environment. A new method of spatial triangle intersection detection based on hierarchical bounding box is proposed, which uses the idea of projection feedback segmentation and surface cell extraction to quickly eliminate most of the patch elements that do not participate in accurate collision detection, and reduces the amount of memory space by using model cache technology. The experimental results show that the intersection detection process reduces the number of accurately detected triangles and improves the efficiency of the algorithm.
