Describe the A-buffer polygon scan conversion algorithm by using 44 sub-pixels for each pixel.
It is possible to symbolize continuous tone grayscale images by using just black ink on white paper because of the limitations in the human visual system. Describe how and why.
describe an algorithm that, 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 that draws a Bezier cubic curve to a specified tolerance by using straight lines.
describe an algorithm for clipping the line against a rectangle.
A Bezier cubic curve could be clipped and drawn by using the algorithm in part (a) to generate straight lines and the algorithm in part (b) to do the clipping. describe a more efficient algorithm which draws a Bezier cubic curve clipped against a rectangle.
