Plane-at-a-Time Clipping

The results of Sutherland-Hodgeman clipping can get complicated very quickly once multiple clip-planes are considered. However, the algorithm is still very simple. Each clip plane is treated independently, and each triangle is treated by one of the four cases mentioned previously.

It is straightforward to extend this algorithm to 3D.
