So, last time, we had set up these things with a slanted plane that was cutting things diagonally.

上次我们，是用斜平面来切割的。

So, as an example, remember at the end of the last lecture, I tried to set up an example where we were looking at a sphere sliced by a slanted plane.

举个例子，大家记得在上次课末尾，我举了个例子,有一个被斜切的球体。
