@Spaceengine : That's good news !I was expecting this for a long time !
Great !

Performance hit is beyond FPS counter accuracy, but possibilities is great. No need to create many new precumputed atmopshere models, which uses a lot of video memory: just take one and change it's color on-the-fly.

But, I never actually understood, what is the actual difference between different atmospheric models, other then in colour?

*reads update*

*dies*

God's work, SpaceEngineer! You have my applause! biggrin





All you need in life are space games and typhlosions.

There's Rayleigh scattering (all-sky scattering of light by molecules of air), Mie scattering (back-scattering of light by dust and aerosols), and extinction (dimming of certain wavelengths of light as they pass through the atmosphere). All of these things, and variables associated with them, can be adjusted independently for each atmosphere model. For example, the atmosphere models of Earth and Neptune are identical except for differing Mie extinction values, and Mie scattering is responsible for the reddish color of the atmosphere of Mars. So colorizing the atmospheres cannot replace having different atmosphere models, but it does mean you can have a large variety using only a small number of models.

So these effects are integral part of the atmosphere model, and cannot be adjusted separately?

I hope that freeing some video memory in that way will not only improve performance in the long run, but will also allow to add more different effects.

Okay so now that we have the chemical composition of the atmospheres, I guess we can imagine the shape of crystals we can found in them, import and use them in Halosim and use photoshop to simulate realistic ice halo displays on unknown planets.
My dream, but I lack knowledge. And motivation, too, seems to be a hard work.

This is sauna planet - looked like a terra with boiled out oceans. Not a far future of Earth:


Finding significant amounts of water in a desert's atmosphere looks extremely impressive to me.

The planet is spinning considerably fast by the way...

=================Some more questions about compositions================
Is the data somewhat linked to other characteristics? Like Cl2 and CH2Cl2 etc. for a Greenworld, or mandatory O2 for all organic multicellular planets.

Will the data concern type and age of host stars? For example, a hot desert near an O8 V and one orbiting a K2 III may behave totally differently in terms of atmpspheric composition (like due to various strengths of solar winds)

Sugestion: the apoapsis and periapsis values for ships orbit could be in relation to te planet surface instead of it's core. is a simple calc: <current peri/apo value> - planet's radius

chemical composition of atmospheres

For the composition of the atmospheres:

Will there always be only the abbreviation, like "CO2" or will it sometime also give the long terms, like "carbon dioxide"?





Don't forget to look here.

Updates what you guys are wanted really long time: chemical composition of atmospheres.

I will not go out home anymore. cry

Question: Does the composition influences the color of the atmosphere or it's just randomized? smile





The universe is not required to be in perfect harmony with human ambition.

CPU: Intel Core i7 4770 GPU: ASUS Radeon R9 270 RAM: 8 GBs

(still don't know why everyone is doing this...)
