摘　　要：基于光线跟踪原理,将光线跟踪算法中光线与物体求交的运算方法运用到虚拟现实的碰撞检测技术中,介绍了光线与平面、球面、二次曲面的碰撞求交及碰撞响应,在VC平台和OpenGL下精确地实现了模型小球的碰撞检测。Based on ray tracing principle, the algorithm of how rays intersect with objects was applied to the technology of collision detection in Virtual Reality system. The intersection of the rays with the plane, spherical surface and conicoid was introduced respectively and the fast and high quality real-time collision detection of representative sphere model was accomplished using OpenGL and Visual C++.
