If we know the material of a surface, we know the BRDF of it.

BRDF is measured for different materials. So in computation, we could simply use BRDF to model different materials.

It was pretty helpful to see this, because I think it made a lot of the material from the last few lectures more concrete. Previously, we had mentioned the "BRDF" at various points when talking about radiometry, global illumination, etc. but it was confusing to understand what exactly the BRDF was, especially because it got mixed in with other concepts like operator notation. After this lecture and Project 3-1, I think the BRDF makes a lot more sense — it's just a way to describe a material by encoding how incoming light gets scattered into outgoing light.
