一种基于等距线的碰撞检测算法

Isometric-line-based Collision Detection Algorithm

碰撞检测是虚拟现实场景模拟中的关键技术之一。文中试图在投影包围盒交集内通过判断等距线与投影线交点个数及位置的方法来构建一种高效优化的碰撞检测算法。该算法在适应虚拟环境的实时性要求的同时,减少了误判的产生。

Collision is a key technique in virtual scenes simulation. A highly efficient collision detection algorithm is obtained by computing the number and position of point （s） of intersection which is between isomet- ric-line and projection line in the field of the projection between bounding boxes. The algorithm is well adapted to the realtimeness of virtual reality with less error.
