The scope has shifted from understanding BRDF's to learn about material models based on the micro facet model, which are nowadays commonly employed in both games and films, what is usualy referred to as "physically based".
As mentioned before, BRDF simply denotes a function that returns reflectance based on view, and light direction, so to learn anything of substance we need to look at the models themselves. The time has come where I finally study lighting. I'm thankful for this jam giving me the incentive.
