Detailed Description

Implements the Shifted Gamma Distribution:

M. M. Bagher, C. Soler, and N. Holzschuch "Accurate fitting of measured reflectances using a Shifted Gamma micro-facet distribution", Computer Graphics Forum 31, 4, 2012: https://doi.org/10.1111/j.1467-8659.2012.03147.x

Includes different variants:

• sgd_base : unnormalized NDF without shadowing or masking
• sgd : NDF with fitted normalization and and approximate shadowing and masking
