Detailed explanation-4: -5. The process of mapping a world window in World Coordinates to the Viewport is called Viewing transformation. Explanation: The viewing transformation is the operation of computer graphics in which the maps are the perspective view of an object in world coordinates into a physical device’s display space.

Detailed explanation-5: -The process of selecting and viewing the picture with different views is called Windowing, and a Process which divides each element of the picture into its visible and invisible portions, allowing the invisible portion to be discarded is called Clipping.
