Practical Construction of Reflectances for Spectral Rendering

  title={Practical Construction of Reflectances for Spectral Rendering},
  author={Qiqi Wang and Haiying Xu and Yinlong Sun},
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
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.

A tool to create illuminant and reflectance spectra for light-driven graphics and visualization
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
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

A full architecture built around spectral light transport and a flexible implementation of multiple importance sampling is described, resulting in a system able to support a comparable amount of extensibility to what made the reyes rendering architecture successful over many decades. Expand
Making choices in multi-dimensional parameter spaces
This dissertation enables effective choices of parameter configurations for different levels of user involvement by developing a space-filling sampling method and devise a method that generates a palette of presets that globally optimize user-specified criteria and regularization. Expand
