We wish to generate two algorithms: one which draws the outline of a circle and one which draws a filled circle.
a) describe an efficient algorithm that will draw a one-pixel wide outline of a circle of integer radius, R, centered on the origin.
b) describe the modifications needed to your algorithm to make it draw a filled circle.
Given a function drawline(x1, y1, x2, y2), describe an algorithm for drawing a Bezier cubic curve to a specified level of accuracy by using only straight lines.
Describe why display devices appear to be capable to reproduce (almost) all the colors of the spectrum by using only red, green and blue light.
Illustrate an algorithm (other than thresholding) that will convert a grayscale image (8 bits per pixel) to a bi-level black and white image (1 bit per pixel), with similar number of pixels, while retaining as much feature as possible.
Describe what specular and diffuse reflection is in the real world. State and describe equations for computing approximations to both in a computer.
