problem1. By making use of appropriate ex, illustrate the Cohen-Sutherland line clipping algorithm.
problem2. Make a distinction between the CMY and RGB colour models.
problem3. Illustrate the concepts of ambient light and diffuse reflection in basic illumination model.
problem4. Illustrate the three conditions associated with the depth sorting technique of visible surface detection where no reordering would be necessary.
problem5. By making use of proper ex, describe how pixel masks may be used to form dashed lines?
problem6. Elucidate the issue associated with vertices when the scan line scan line polygon fill algorithm is being applied?

problem8. By making use of proper exs, illustrate the following anti-aliasing techniques:
b. Area sampling
c. Pixel phasing
problem9. When dealing with CIE chromaticity, describe how “shade” and “tint” effects may be produced to an original colour?
