It's unfortunate transition time when they cannot be updated separately, not at least without some ugly patching. Make Stellarium use static release tarball instead of the generated by GitHub one. While currently it does not win us much, next version will be additionally offering smaller .tar.xz distfile which we'll switch to more easily. Enforce Qt5 build for now. While Stellarium and its dependencies are Qt6-ready, providing correct and coherent flavors for all of them is too much work for little gain. Everyone should be using Qt5 anyways. PR: 266915

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.
