Design and realization of 3D game based on 3D desktop OS
基于三维桌面操作系统的3D游戏设计与实现*

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.
