 Question 6
Which of the following statement(s) is/are incorrect ?
 A Mapping the coordinates of the points and lines that form the picture into the appropriate coordinates on the device or workstation is known as viewing transformation. B The coordinate system that corresponds to the device or workstation where the image is to be displayed is known as physical device coordinate system C The right-handed cartesian coordinates system in whose coordinates we describe the picture is known as world coordinate system. D Left - handed coordinate system in which the display area of the virtual display device corresponds to the unit (|x|) square whose lower left-hand corner is at the origin of the coordinate system, is known as normalized device coordinate system.
