Q17. P3,j15. Which of the following statements are incorrect?

1.       Mapping the coordinates of the points and lines that form the pictures into the appropriate coordinates on the devices or workstations  is known as viewing transformation.

2.       The right handed Cartesian coordinate  system in whose coordinate we describe the picture is known as world coordinate system.

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

4.       Left hand coordinate system In which the displayed area of the virtual device corresponds to unit |x| square whose left hand corner is at the origin of the coordinate system, is known as normalized device coordinate system.

Codes

A)     I only.   B)1 and 2.     C) 3 only      D) 4 only.

Answer D.

Explanation.

In normalized device coordinate system lower left corner corresponds to (0,0) and upper right corner corresponds to (1,1).
