A single colorAs we saw in Chapter 3, a shader calculates some output value based on a standard set of input data and the parameters chosen for the shader. Now we’ll see how these concepts are implemented in C.

The transparency of a surfaceIn 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.

Light on a surfaceIn our discussion of light shaders in the last chapter, we used a simple material shader that took the light into account to define the color of the surface. In this chapter, we’ll use our light shader with a variety of material shaders that approximate the affect of diffuse and mirror-like reflections from a surface.
