Controlled capture of real‐world material appearance yields tabulated sets of highly realistic reflectance data. In practice, however, its high memory footprint requires compressing into a representation that can be used efficiently in rendering while remaining faithful to the original. Previous works in appearance encoding often prioritized one of these requirements at the expense of the other, by either applying high‐fidelity array compression strategies not suited for efficient queries… 

Metappearance: Meta-Learning for Visual Appearance Reproduction

This work suggests to combine both techniques end-to-end using meta-learning: over-fit onto a single problem instance in an inner loop, while also learning how to do so efficiently in an outer-loop that builds intuition over many optimization runs.

Neural BTF Compression and Interpolation

A neural network‐based BTF representation inspired by autoencoders is proposed: the encoder compresses each texel to a small set of latent coefficients, while the decoder additionally takes in a light and view direction and outputs a single RGB vector at a time, eliminating the need for linear interpolation between discrete samples.
