This paper proposes two novel contributions for real-time rendering of diffraction in surface reflectance, including practical measurement of diffraction irradiance for data-driven rendering and novel measurement of diffraction gratings using bokeh photography.

Introducing an extension to microfacet theory for rendering iridescent effects caused by thin films of varying thickness on top of an arbitrarily rough base layer. The material model is the first to produce a consistent appearance between tristimulus (RGB) and spectral rendering engines.

Measured material reflectance contains complex effects. Micro-facet material models (Cook-Torrance) have difficulties representing these effects. This paper explains the differences between measured reflectance and material models by taking into account diffraction effects in a two-scale model.

This work derives a compact BCSDF model for fur reflectance with only 5 lobes.
The model unifies hair and fur rendering, and enables a multi-scale rendering scheme that transitions between near- and far-field rendering smoothly for the first time, leading to 6-8x acceleration over previous work.
