摘　　要：为了实现内嵌于三维桌面操作系统的一款3D益智小游戏,结合游戏具体的开发过程,讨论并解决了在设计中遇到的随机切割、三维鼠标拾取操作和碰撞检测关键问题。通过使用包围盒检测、相交检测和方向向量检测方法加速了游戏的碰撞检测处理,使渲染速度提升了34.8%,最终游戏能够以31 fps的速度流畅地运行。In order to realize a three-dimensional puzzle game embedded in the 3D desktop OS, this paper took the actual development of this game for example, and resolved several designed problems, which included the random cutting, the three-dimensional mouse pick-up operation and the collision detection. The algorithm based on bounding box the intersection detection and the direction vector detection, accelerates the computation speed of collision detection. The experimental result shows above method gets 34.8% performance promotion. In final, the game runs smoothly at the rendering speed of 31 frames per second.
