Abstract: 3D graphics system is the subsystem of 3D game engine，in charge of handling the data structure and rending the 3D world from camera or player view.The most important function in it is geometry culling.The article analyzes the theory of culling and brings forward a new culling arithmetic idea and gives most VC code.
Key words: 3D graphics system, 3D pipeline, geometry culling, culling arithmetic
摘要： 三维图形系统是三维游戏引擎中的子引擎部分，负责处理三维世界的数据结构以及从玩家或相机所在的视点渲染三维世界。其中的一个重要问题就是物体剪裁问题。对物体裁剪的工作原理进行了详细的分析，提出了一个新的简便的裁剪算法，并给出了该算法的关键代码。
