We propose a method to construct practical reflectances for spectral rendering. A set of 1400 real reflectances are measured and more spectra with higher saturated colors are generated using Bouguer’s law. These spectra serve as the basis for constructing the spectra for any colors. Given a color triplet P, in the color space, we find a small local tetrahedron that contains P and the reflectances at the vertices are known. Thus the spectrum at P is constructed using trilinear interpolation. Our… Expand
Reconstruction of Spectra Using Empirical Basis Functions
TLDR
This work designs three different comparison scenarios typical for computer graphic applications to evaluate the suitability of the methods to reconstruct illumination and reflectance spectra and proposes a novel approach applying empirical mean spectra as basis functions to reconstruct spectral distributions.

Spectral Primary Decomposition for Rendering with sRGB Reflectance
TLDR
It is shown for the first time that it is possible to create any sRGB reflectance spectrum as a linear combination of three separate spectra, each directly corresponding to one of the BT.709 primaries. Expand
A tool to create illuminant and reflectance spectra for light-driven graphics and visualization
TLDR
A tool to augment a palette of given lights and material reflectances with constructed spectra, yielding specified colors or spectral properties such as metamerism or objective color constancy, which enhances the user's freedom in designing photo-realistic scenes and helps in creating expressive visualizations.

Physically Meaningful Rendering using Tristimulus Colours
TLDR
By comparing to spectral reference renderings, it is shown how rendering in tristimulus colour spaces introduces colour shifts in indirect light, violation of energy conservation, and unexpected behaviour in participating media. Expand
