Detailed explanation-1: -Correct choice is (a) True Easiest 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-2: -Window to Viewport Transformation is the process of transforming 2D world-coordinate objects to device coordinates. Objects inside the world or clipping window are mapped to the viewport which is the area on the screen where world coordinates are mapped to be displayed.
Detailed explanation-3: -Viewing Transformation is the mapping of coordinates of points and lines that form the picture into appropriate coordinates on the display device. World coordinate system (WCS) is the right handed cartesian co-ordinate system where we define the picture to be displayed.
Detailed explanation-4: -In general, the mapping of a part of a world-coordinate scene to device coordinates is referred to as a viewing transformation. Sometimes the two-dimensional viewing transformation is simply referred to as the window-to-viewport transformation or the windowing transformation.
