Note: Attempt any FIVE questions.All questions carry equal marks.The students can use only non programmable and non-storage type calculator.
1.(a) What is meant by aspect ratio?
(b) Explain the difference between a general graphics system designed for a programmer and one designed for a specific application, such as architectural design.
(c) Explain the working of plasma panel display.
2. (a) compute the intermediate points on the line drawn from (0,0)to (5,10) using bresenhams
algorithm.
(b) What are the refreshing display devices? Describe the working principle of CRT display with
the help of suitable diagram. Differentiate between random and raster scan display devices.
