describe the z-buffer polygon scan conversion algorithm.
Describe how the A-buffer enhances on the z-buffer.
Describe what a form factor is (in radiosity). Outline an implementable method of computing form factors.
describe an algorithm to draw a straight line by using only integer arithmetic. You might suppose that the line is in the first octant that the line begins and ends at integer coordinates, and that the function setpixel(x; y) turns on the pixel at location (x; y).
Describe how straight lines can be employed to draw the Bezier cubic curves.
