Abstract: There is provided a system and method for artist friendly control of three-dimensional object shading, particularly hair. A methodology is disclosed for deriving a pseudo scattering function over a domain of Artist Friendly Controls (AFCs) from a physically based scattering function over a domain of Physically Based Controls (PBCs). The pseudo scattering function can provide intuitive decoupled adjustments of specific important visual characteristics while still providing a convincing and aesthetically pleasing result. An end user such as an artist may thus control the values, or AFCs, to implement specific aesthetic features for the shading of objects as seen on a display. The pseudo scattering function may be utilized for single scattering and multiple scattering models of hair shading.
