Computer Graphics is the research field that tries to replicate the world around us using Computer Science. It is concerned with modelling reality and image synthesis from virtual 3D scenes. It can be seen as the opposite of Computer Vision.
A standalone C++ 17 implementation of the sky radiance models described in the papers "A Wide Spectral Range Sky Radiance Model" and "A Fitted Radiance and Attenuation Model for Realistic Atmospheres". It contains the model library together with a simple example renderer and a GUI frontend to illustrate how to use it.
