Topics for the Week of Sept 7, 2010
CS 445: Computer Graphics

• Lab 1: Building a Ray Tracer (3 weeks)
  • Tues: Look at student work for part 1. Begin part 2.
• Ray Tracing:
  • Continue discussion of Notes (pdf)
  • Review point and vector arithmetic, e.g. dot products, cross products, parameterization along a line/ray/segment.
  • Calculating intersections of rays and objects. For this, we need the equations of
    • Spheres
    • Plane
    • Cylinder
    • Cones
    • Algebraic Surfaces
    • Steiner Surfaces
• Phong Lighting - Note, we will need normals for all of the above shapes.
• For an entertaining lecture on lighting, see Knoll's Computer Class, episode 1
