If a three D transformation squishes face onto a plane, there's also a full line of vectors that land on the origin.

如果一个三维变换把一个面压在一个平面上 也会有一整条向量落在原点上。

If, let's say, Moana is falling through the sky and her hair's really stretched, well, how much of her hair is going to be a full straight line versus how much curl is going to be there?

Nadim：比方说， 如果莫阿娜从天而降， 她的头发真的被拉长了，那么，她的头发中有多少会是一条完整的直线， 有多少会是卷曲的？
