Detailed Description

Parameterization of the UNIFIED reflection model.

Parameters:

• specular_spike : Reflection probability at the average surface normal.
• specular_lobe : Reflection probability at the micro facet normal.
• backscatter : Probability of back scattering 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.
