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