Spectral Rendering with the Bounded MESE and sRGB Data
(The Eurographics Association, 2019)
In a recent journal paper, we introduced a technique to represent reflectance spectra by an arbitrary number of Fourier coefficients. As a special case, we converted tristimulus data to three Fourier coefficients. After ...
A Simple Diffuse Fluorescent BBRRDF Model
(The Eurographics Association, 2018)
Fluorescence - the effect of a photon being absorbed at one wavelength and re-emitted at another - is present in many common materials such as clothes and paper. Yet there has been little research in rendering or modeling ...
Improving Spectral Upsampling with Fluorescence
(The Eurographics Association, 2020)
Modern photorealistic rendering simulates spectral behaviour of light. Since many assets are still created in different RGB color spaces, spectral upsampling of the RGB colors to a spectral representation is required to ...
