我已经阅读了大部分代码，并且也知道项目大体的运行框架，但是对于计算视野可见地图格子相关算法，我看的不是很懂
但是问题其实也不在这，我遇到的问题是，在Example1场景中，到达特定的地形处，会出现战争迷雾闪烁的Bug
原因我也找到了，如果在一次计算可见性区域后进入EndUpdate状态（我称他为奇怪的状态，因为我看不懂）

这个状态下，RefreshFOWTexture方法不会更新Color缓冲区，而是直接返回true

然后当前帧可见性（color.g）与前一帧可见性（color.r）的会不断循环地从0~1插值，然后就会闪烁

我现在是加了一个trick来暂时解决这个问题的

如果可以的话，请告诉我这个问题的原因（迷雾可见性的算法），非常感谢
