Implementation
This topic is mostly independent of OpenGL - all graphics systems have to clip, render lines, etc.
Advantage of using Cohen-Sutherland:
- You always have to use the detailed clipping since sometimes the CS algotihm reports that it doesn't know.
- However often it can classify the line segment (or the box with everything inside) as either completely in or else completely out.
- In that case, the rest of the pipeline is faster.
- However you have to write more lines of code.
- You don't have to know how this works, only what its purpose is.
