This blog covers research and practice of the PBR rendering style in computer graphics. It includes mathematical formulas (such as BRDF integrals, rendering equations, and bidirectional reflection distribution functions), major methodological models (Lambertian, Phong, and Blinn-Phong), and a record of the production process in the Unity shader graph.
