Abstract
In previous chapters, we have used variables in the state struct to calculate the color of the surface. We’ve also used a few of the mental ray library functions, like the mi-eval functions for parameters, and some utility functions, like mi_vector_dot. In this chapter, we use a function that examines the rendering environment through ray tracing.
