Our previous insights regarding the Smith model and the masking-shadowing function.; We briefly discussed the connection between the normalization coefficient of microflake phase functions and the Smith masking function in our SGGX paper.; The explicit Beckmann surfaces used to validate our model’s predictions were … Websurface they want to model for their BSDF derivation. In Sec-tion4.1, we show that the first non-classical aspect of their model is that the anisotropic cross-sections of this matter density are non-symmetric to direction—the interaction probability when passing through a given location in the medium is not identical to the case

We omit any reflecting and refracting interfaces between the layers. The first advantage of this formulation is that an exact and analytic solution for single scattering, regardless of ...
