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.
astro/calcmysky: the port had been updated to version 0.3.4
This release includes some small fixes that accumulated over
the last half a year.

astro/calcmysky: the port had been updated to version 0.3.2
GLM_ENABLE_EXPERIMENTAL is now defined at the source level,
so we can drop CXXFLAGS+= from the Makefile.

math/glm: update 0.9.9.8 → 1.0.1
Some parts of glm were retroactively marked as experimental, and using
now leads to a compile error - added override for this error to consumers
which need it.
astro/calcmysky: the port had been updated to version 0.3.1
This release fixes some rendering issues:
- On GPUs that compute mipmaps of non-power-of-two textures
poorly eclipsed atmosphere rendering now works as expected
- Atmosphere model examples now don't include Rayleigh phase
function in the texture -- this change fixes a "round cap
around zenith" artifact

astro/{calcmysky,stellarium}: update both ports to the latest versions
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.

astro/calcmysky: new port had been added (+)
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 draw realistic sky in applications such as
planetaria, e.g. `astro/stellarium'.
