describe the A-buffer polygon scan conversion algorithm by using 44 sub-pixels in all pixels.
It is possible to signify continuous tone grayscale images by using just black ink on white paper as of limitations in the human visual system. Describe how and why.
describe an algorithm which, given a grayscale image, will generate a black and white (bi-level) image of four times the resolution in each dimension which gives a good approximation to the grayscale image.
describe an algorithm which draws a Bezier cubic curve to a specified tolerance by using straight lines.
Illustrate an algorithm for clipping a line against a rectangle.
A Bezier cubic curve could be clipped and drawn by using the algorithm in (1) to produce straight lines and the algorithm in (b) to do the clipping. Illustrate a more efficient algorithm that draws a Bezier cubic curve clipped against the rectangle.
