Clipping human face in 3D world

Inspired by GANTZ from Japanese animation.

Background

In my previous post, I mention to create stencil seal on the object. In that, invisible planes crop the object off. You can see the example in this site quickly as I referred to the code. This means something inside the content come out by slashing it. While learning Three.js from the example, I figured out that the resulting image looked like Japanese animation called GANTZ. You can see my inspired vision in the following official tweet.
