| 摘 要： | 提出了一种基于碰撞检测的触觉渲染优化方法，根据触觉设备的运动状态，在主线程中动态构造一个包围盒，使用方向包围盒（OBB）碰撞检测方法裁减掉大量的不可能“触摸？’到的三角面片集，只渲染可能“触摸’，到的三角面片来。实例分析表明优化后的触觉渲染算法占用时间基本不受场景中三角面片数量的影响，适合虚拟装配场景的触觉渲染。

| Abstract: | An optimization method based on collision detection was proposed. According to the movement states of haptic device, a bounding box was constructed dynamically in the main process, then an improved oriented bounding box (OBB) collision detection method was used to prune a large number of untouchable triangle collections, and the remnants were rendered separately in haptic process. The results of practical instances depict that the runtime of the improved method is stable with little influence by the number of triangle in scene, which verifies that this optimization method for rendering is suitable for haptic rendering of virtual assembly scene. |
