TU Wien Rendering #3 - BRDF models, The Rendering Equation

There are many materials in the world that we’d like to model in our program: mirrors, walls, car paint and so on. How do we characterize these different material properties mathematically? We use BRDFs (Bidirectional reflectance distribution functions) as a vehicle to accomplish this, and also discuss how to use it to formulate the holy grail of computer graphics, the rendering equation, the most fundamental equation of light transport. About the course: This course aims to give an overview of basic and s
