All questions are of equal weight.

• Provide a pseudo-code implementation for the three dimensional extension of the Koch curve depicted in figure 10-74 page 369 of your book.
• Implement backface detection and removal in your last graphics programming project.
• Extend the Sutherland Hodgman polygon clipping algorithm to clip three-dimensional planes against a regular parallelpiped. Provide pseudo-code.
• Create a chart describing the various methods of rendering a scene discussed in this class. Include strong points, weak points and relative time consumed.
• Set up a scene for a raytracer that includes at least a light source, a sphere, and a polygon object. Sketch this scene. Show the calculations for:
  • A ray that misses everything in the scene
  • A point on one object that is shadowed by another object.
  • A point of one object that reflects another object.
  You do not need to use a raytracer for this question. You MUST show your calculations.
