Anisotropic Phong shader is based on the Renderman shader by Peter Stuart Also from the research paper An Anisotropic Phong Light Reflection Model by Michael Ashikhmin and Peter Shirley. The paper presents a BRDF model that combines several advantages of the various empirical models…

Brdf Scatter shader is based on the research paper “A Practical Model for Subsurface Light Transport” by Henrik Wann Jensen. The shader implements a BRDF approximation of a bssrdf as described in the research paper. It can handle materials that look more like wax, jade,…

DT3D skin shader is an oren nayar based shader with at the moment 54 controllable attributes that control the subsurface scattering and the many specular layers. It has 4 functions contributing to the subsurface scattering, that range in different effects that happen when light…

Car Paint shader is based on the Renderman shader by Peter Stuart Also from the research paper A Simple Layered RGB BRDF Model by Xavier Granier and Wolfgang Heidrich. The model simulates the interaction (interference) of light with itself due to a thin substrate. To completely…

Single Scatter shader is based on the research paper “Analytic Approximations for Light Transport in Volumetric Materials”. The shader is based on single scattering approximations to mimic scattering of light within a material. This shader gives the user artistic control…
