Hosek–Wilkie sky model
The Physical sky is a JavaScript port of the spectral Hosek–Wilkie sky model (ArHosekSkyModel 1.4a), with its coefficient tables taken from the copy bundled with pbrt-v4. It's described in L. Hosek and A. Wilkie, "An Analytic Model for Full Spectral Sky-Dome Radiance", ACM Transactions on Graphics 31(4), 2012, and "Adding a Solar-Radiance Function to the Hosek–Wilkie Skylight Model", IEEE Computer Graphics and Applications 33(3), 2013.

Color data and pbrt-v4
Auddomate's color science uses the CIE 1931 2° standard observer and the CIE standard illuminant D65, standard data published by the International Commission on Illumination (ISO/CIE 11664-1 and 11664-2). Our copy was taken from pbrt-v4, copyright Matt Pharr, Wenzel Jakob and Greg Humphreys, which is licensed under the Apache License 2.0.
pbrt-v4 is also the independent reference renderer Auddomate checks itself against. Auddomate is not affiliated with, endorsed by or certified by pbrt-v4 or its authors.
Published research
These methods are implemented independently in Auddomate from their published descriptions:
- Spectral upsampling, turning colors into spectra: W. Jakob and J. Hanika, "A Low-Dimensional Function Space for Efficient Spectral Upsampling", Computer Graphics Forum 38(2), 2019.
- Choosing wavelengths, and many of the conventions that keep Auddomate comparable to its reference: M. Pharr, W. Jakob and G. Humphreys, Physically Based Rendering: From Theory to Implementation, 4th edition, MIT Press, 2023.
Lucid UI
The studio's interface, from its panels and sliders to its menus, dialogs and command menu, is built with Lucid UI, an open-source interface library for people and agents alike. It's used under the MIT licence.
