TauBench is a dynamic graphics rendering benchmark dataset, targeted especially towards rendering methods relying on the reuse of temporal data. The dataset is available at https://doi.org/10.5281/zenodo.5729573, and this upload provides path traced reference frames for it in PNG format. The images are rendered with Tauray at 16384 samples per pixel (spp), at both 1080p and 2160p resolutions. Frame indices start from 0 and are not padded with leading zeroes.
