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.
|
|
|
|
The simulation is based on E. Bruneton's "Precomputed Atmospheric
|
|
Scattering" paper and the updated implementation of the demo. This in
|
|
particular limits the atmosphere to spherical symmetry (which means
|
|
localized clouds are not supported, and ground albedo is the same all
|
|
around the globe).
|
|
|
|
An additional capability is simulation of solar eclipses, which is
|
|
currently limited to two scattering orders, while the non-eclipsed
|
|
atmosphere can be simulated to arbitrary order.
