Celestial Demo
From CSP
[edit]
Celestial Demo
This was my first CSP project. Using several online references (see below), I wrote routines to accurately position the sun, moon, and stars in the sky for the next 400 years or so. I also implemented some colorspace transformations and atmospheric rendering models to produce quasi-realistic looking sky domes. The code was originally written in Python, but has since been ported to C++ and integrated with CSPSim. --Onsight
