Light in Unity 2. Intro to Blinn Phong Lighting model

WebTechnically, Blinn-Phong is considered a BRDF taking the same ω i and ω o as inputs. However, Blinn-Phong is not considered physically based as it doesn't adhere to the energy conservation principle. There are several physically based BRDFs out there to approximate the surface's reaction to light. WebThe Blinn model uses a different set of vectors for its computations, one that are less than 90 degrees in all valid cases. The Blinn model requires computing the half-angle vector.
