Question 7556 – UGC NET CS 2015 June Paper-3

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.

The coordinate system that corresponds to the device or workstation where the image is to be displayed is known as physical device coordinate system

The right-handed cartesian coordinates system in whose coordinates we describe the picture is known as world coordinate system.

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.
