Core to our method is a principled reduction technique that encodes the reradiation into a low-dimensional matrix working in the space of the renderer's Color Matching Functions (CMFs). Our process is independent of a specific CMF set and allows for the addition of a non-visible ultraviolet band during light transport. Our representation visually matches full spectral light transport for measured fluorescent materials even for challenging illuminants.Attribution 4.0 International License10.1111/cgf.151509 pages
