This paper presents a model for the anisotropic scattering of polarized light based upon the physics of light; which is capable of calculating both partial and complete polarization using a combination of Jones and Mueller calculus, as well as incorporating self shadowing effects.CR Categories and Subject Descriptors: I.3.3 [Computer Graphics]: Three-Dimensional Graphics and Realism - Raytracing;
