Cohen Sutherland Line Clippings Algorithm
Illustrate the term Cohen Sutherland Line Clippings Algorithm in brief.
Expert
In Cohen Sutherland Line Clipping, the clipping problem is made simpler by dividing the region surrounding the window region into the four segments: up, down, left, right, (UDLR) and assignment of number 1 and 0 to the respective segments helps in positioning the region surrounding the window. However the limitation of Cohen Sutherland Line Clippings is that this algorithm is just applicable to the rectangular windows and not to any other convex shaped window.
