Define window, viewport and viewing transformation. Let ABCD be the regular window with A(20, 20), B(90, 20), C(90, 70), and D(20, 70). Find the region codes for end points and use Cohen Sutherland algorithm to clip the lines P(10, 30) Q(80, 90).

Window: A rectangular region defined in the world coordinate system that selects the portion of a scene to be displayed. Only objects lying inside the window are shown. Viewport: A rectangular region on the display device (screen, in device/normalized coordinates) onto which the contents of the w...
