is there anyone can tell me how to use that cohen-sutherland algorithm??i want to make a simple line clipping program…xcly i don’t really understand this algorithm… 
Hello,
do you understand german?
In this case i could send you a fine paper from my University that explains this algorithm very well.
If not, post your Problem, why you don´t understand this algo, i and sure others would explain it here - so i think.
Best regards

It’s rather straight-forward. What is it that you don’t understand?
there’s tons of info on this if you google it.
EDIT: i found this: it’s an applet that takes you thru the algorithm…it should help you out:
