Adaptive highlights stencils for modeling of multi-axial BRDF anisotropy

Directionally dependent anisotropic material appearance phenomenon is widely represented using bidirectional reflectance distribution function (BRDF). This function needs in practice either reconstruction of unknown values interpolating between sparse measured samples or requires data fidelity prese...
