Frequency Analysis of Light Transport

Frequency analysis of light transport is a theoretical framework to enables to predict the local behaviour of light during its transport (after multiple reflexion/refraction/scattering). Because of its predictive nature, this tool can be used to predict denoising kernels for unconverged light transport simulation or to adapt the sampling budget locally.
