Interestingly enough I always thought something close to that level of brightness would be pretty cool when you were around the area of Mercury's orbit or an even closer asteroid, and then became a pleasant glow around Earth, and as you got out into the outer solar system the HDR would switch signs and become kind of an abyssal gloom out in the Kuiper belt.

Martin in another post explained why changing light levels based on AU is bad. Mainly due to displays and how the eye perceives light.

Cras, I desperately need a second opinion

Please check it out once again. Does this look good?

Edge of atmosphere is quite sharp. Raytraced color looks ok.

**Cras** · 06-05-2012, 03:48 PM

I am gonna look around, maybe dive into the NASA photograhy archives and see if I can find some comparable pictures and compare. there are a lot of things that are subtle, but need to be right It is sort of like you wont notice them until they are wrong, then they really stand out. Such as the heigh of the haze, how it fades on the dark side, things like that. The dark side of the earth should never show a horizon I dont think. It should transition to shadow and thus the edge be soft.

Notice how the Sun appears "under" the atmosphere.

Sunset from Earth orbit, seen from the International Space Station (ISS). The glow of the setting Sun is lighting up the atmosphere (blue) on the gently curving horizon that separates the Earth (bottom) from space (top). The atmosphere is around 100 kilometres thick, a relatively thin layer of air compared to the size of the Earth itself. Photographed on 23 November 2009 during mission STS-129 by the Space Shuttle Atlantis to the ISS.

Just a quick question: Would it be possible to disable the bloom effect on vessels? That is something that has bugged me for a while when it comes to the D3D11Client.

No, it isn't since bloom is post-processing effect. Besides, if the vessel is bright in current light conditions - it should glow.

Yes I know, but on the other hand - this is not a raytraced image, so some things will inevitably be missing, or slightly wrong. I want it to be as close to reality as possible, but I also understand that there are technological limits to what can we do to achieve that - and that will keep being the case until video card's performance envelope reaches a point where it would be possible to do a real-time raytracing...

Also please check how HDR in general feels. I've made some tunes in that area as well and would like to get some feedback on that item too.

Asmi, take a look on it, under atmosphere section:
http://evasion.inrialpes.fr/~Eric.Bruneton/

IMHO the best available publication. Also you can find other amazing things there

That's what we currently use for atmosphere model.

I personally think that looks absolutely amazing.

OK, let's wait for a word from Cras, so I can put a checkmark for that item

Then on to the standardized terrain engine?

You know. So I can finally wipe the drool off my keyboard?

Nope - I've got other things that wait to be fixed before doing that...
