Detailed Description

Parameterization of the UNIFIED reflection model.

The reflection grids store the probability of each angular distribution in the UNIFIED model:

specular_spike : Reflection probability at the average surface normal.
specular_lobe : Reflection probability at the micro facet normal.
backscatter : Probability of backscattering after reflecting within a deep groove.

The sum of all three parameters must be <= 1 at every grid point, with the remainder being the probability of diffuse scattering.

Todo:: We could require these to all be on the same energy grid for improved performance and error checking.
