Today we will talk about this paper that was presented at EUROGRAPHICS 2022, by Basile Fraboni, Antoine Webanck, Nicolas Bonneel, and Jean-Claude Iehl, from INSA Lyon and Univ Lyon. In it, they propose a new method for efficiently rendering volumetric effects like clouds or smoke in cases where sequences of frames (or multiple camera views) are needed, in which they reuse light paths across different frames, and propose a Multiple Weighted Importance Sampling estimator to handle these contributions from the shared paths.Read full paper:
