Abstract
A method and computing system for rendering subsurface scattering are provided. An optical property and a thickness are received for each of a plurality of material layers. A latent space is trained for each of the plurality of material layers. A global transfer matrix is generated for at least one multi-layer material, each of the at least one multi-layer material including an ordered set of material layers selected from the plurality of material layers, by determining a transfer matrix for each adjacent pair of material layers in the ordered set of material layers using the latent space for each material layer in the adjacent pair of material layers, the transfer matrix describing angular and azimuthal reflectance and angular and azimuthal transmittance, and determining the global transfer matrix as a product of the transfer matrices of each adjacent pair of material layers.
