Surfaces reflect. Glass, water, and similar materials both reflect and refract. The reflection and refraction formulas are at the heart of ray tracing. These are not easy to find in the literature in the vector forms needed for generating rays. This chapter is a reference for determining outgoing ray directions under simplified, ideal conditions.
