Summary
In this course note, we introduced a new physically based shading model, and we used this single, general-purpose BRDF on all materials (except hair). This model, which has come to be known as the Disney BRDF, is able to reproduce a wide range of materials with only a few parameters. For our next film, Frozen, we continued to use this BRDF unmodified, but effects like refraction and subsurface scattering were computed separately from the BRDF, and indirect illumination was approximated using point clouds
