problem 1:
describe the A-buffer polygon scan conversion algorithm by using 44 sub-pixels in all pixels.
problem 2:
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.
problem 3:
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.
problem 4:
describe an algorithm which draws a Bezier cubic curve to a specified tolerance by using straight lines.
problem 5:
Illustrate an algorithm for clipping a line against a rectangle.
problem 6:
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.
