Which among the following is best suited for a realistic shaded image drawing on the screen?

A. Random Scan Display Algorithm

B. Raster Scan Display Algorithm

C. Both a. and b.

D. None of the above

Correct Answer :

B. Raster Scan Display Algorithm


The Raster scan display algorithm is best suited for realistic shaded drawing because it is works upon the intensity of the pixels. Hence, the value of every pixel is assigned from the starting pixel to the ending one. Hence, a shaded realistic image can be best drawn using this technique.
