说明：  这是一本介绍实时碰撞检测算法的书籍，是一个老外写的，中国人翻译的，书中对碰撞检测算法和相关数学知识都做了详细了介绍，还贴有源码，对碰撞检测理论和代码感兴趣的可以学习到很多东西
(This is a Book Introducing real-time collision detection algorithm, which was written by a foreigner and translated by Chinese. The book gives a detailed introduction to collision detection algorithm and related mathematical knowledge. It also pastes source code. You can learn a lot from the theory and code of collision detection.)
