CalcMySky is a software package that simulates scattering of light by the
atmosphere to render daytime and twilight skies (without stars). Its primary
purpose is to enable realistic view of the sky in applications such as
planetaria. Secondary objective is to make it possible to explore atmospheric
effects such as glories, fogbows etc., as well as simulate unusual environments
such as on Mars or an exoplanet orbiting a star with a non-solar spectrum of
radiation.
