Polygon Clipping

1. The Cohen-Sutherland Algorithm is used to clip lines against a window. How does this algorithm proceed.   
2. Outline how you would extend the algorithm in b) above to three dimensions.
3. Describe in detail the Sutherland-Hodgeman clipping algorithm for clipping one polygon against another.
