DESCRIPTION

Cohen-Sutherland Line Clipping Algorithm 1.End points are checked to for trivial acceptance – If both endpoints are inside the clip rectangle boundary 2.If not trivially accepted, region check is done for trivial rejection Both endpoints have x co-ordinate less than x min  region to the left edge of clip rectangle Both endpoints have x co-ordinate greater than x max  region to the right edge of clip rectangle Both endpoints have y co-ordinate less than y min  region below the bottom edge of clip rectangle Both endpoints have y co-ordinate greater than y max  region above the top edge of clip rectangle
