Dear all users and core developers,
Several potential end-users mention that the current name of the library makes people think that hpp-fcl is nothing more than a simple fork of the original FCL. …

最近在看box2d的源码,看得好累。发现box2d的碰撞检测不止用到了SAT(分离轴)算法,还有**GJK算法**和V-clip算法(连google都找不到的冷门算法,不知道具体原理)。box2d貌似把3种算法糅合起来了,根本看不懂。
不过看到GJK时,我上网了解了一下,感觉眼前一亮,因为看到一种跟分离轴思路完全不同的碰撞检测算法还是很开心的。和SAT一样,GJK算法也只对凸多边形有…
