Due Nov 8 in lab.

- What is the difference between Gouraud and Phong shading?
- Can Gouraud shading produce a highlight in the interior of a face?
- Can Phong shading produce a highlight in the interior of a face?
- Is Gouraud shading faster than Phong?
- Can the standard OpenGL pipeline easily handle light scattering from object to object?
- How did Phong model surfaces of different shininess? I.e., what changed in his equation?
- Why does OpenGL requires you explicitly to enable shading, instead of having it on all the time?
- Draw or describe a set of 3 polygons that the painters algorithm cannot handle, w/o cutting one of the polygons into two pieces.
- What's the big advantage of the binary space partitioning algorithm?
- Draw a polygon that will be cut into two parts when clipped.
- How many stages of the pipeline are used for 3D clipping in the SGI Geometry Engine?
- What's different about a spot light (compared to a nonspot light)?
- Do the Bresenham line algorithm for a line from (0,0) to (11,7).
- Do the Bresenham circle algorithm for a circle of radius 20.
- Hand in a progress report on the term project.
