The BresenhamAlgorithm creates exactly the same result as the simple DDA, but suffices using only integer arithmetic. Thus it is faster, easier to implement in firm or hardware, and The CohenSutherland LineClipping Algorithm. The more efficient CohenSutherland Algorithm performs initial tests on a line to determine whether intersection calculations can be avoided.
