一种基于光线跟踪的碰撞检测算法的研究与实现

his paper respectively from the collision detection among spheriods with planes,cylinders analyzed the ray tracing principle and realized the algorithm. Real-time,accuracy and integrity are the key targets of the collision detection in virtual reality system, but the ray tracing principle has limited application for 3D complex scene beacause of massive computations for intersection of rays with erery object. However,in the view of the simple scence, this algorithm meets real-time and precise for people\\\??s requirement. Based on ray tracing principle using Win32 platform and OpenGL,the experimental results indicate that this approach is both effective and realistic.
