CS-419 Production Computer Graphics

• be able to render at least one sphere and at least one plane (you do not need to build complex primitive reading software)
• render refraction, diffuse reflection and specular reflection
• produce an image

Use this program to produce two images that illustrate errors produced by pruning the ray tree at fixed depth no less than two. One should show (about!) the right answer, the second the error that results when one uses such pruning. I am looking for a good illustration, so spend more time thinking about the composition of the scene and little time thinking about efficiency, reading primitives, and the like.

You should do this exercise individually. Images are due 7 Sep. Email them to me at daf@uiuc.edu, with "CS419" in the header
