Lighting
•BRDF = Bidirectional Reflectance Distribution Function
–Description of how the surface interacts with incident light and emits reflected light
–Isotropic
•Independent of absolute incident and reflected angles
–Anisotropic
•Absolute angles matter
–Don’t forget the generalizations to the BRDF!
•Spatially/spectrally varying, florescence, phosphorescence, etc.
