Moment-based Constrained Spectral Uplifting
(The Eurographics Association, 2021)
Spectral rendering is increasingly used in appearance-critical rendering workflows due to its ability to predict colour values under varying illuminants. However, directly modelling assets via input of spectral data is a ...
A Compact Representation for Fluorescent Spectral Data
(The Eurographics Association, 2021)
We propose a technique to efficiently importance sample and store fluorescent spectral data. Fluorescence behaviour is properly represented as a re-radiation matrix: for a given input wavelength, this matrix indicates how ...
