New atmospheric model
« on: October 07, 2010, 03:46:27 pm »
A few preliminary screenshots for comparison of enhanced atmospheric model.
The new model is more precise than the old one, resulting in better colors and less artifacts. With the old one the sky is usually darker than it should be, and in some conditions it failed to capture the colors.

The new model is also slightly faster but more importantly it allows additional optimizations on other parts of the pipeline.

New one on the left, the old one on the right.

I do like how the effects are more consistent now.  Well done. :)

Nicely done :)  Like Raiko said, looks a lot more consistent and realistic.

Wow. I was so busy with the newly launced ISI forums I forgot to check here.

Probably a good side effect.

Is there Groundfog integrated? That would be nice. ;)

While this part of the engine wasn't specifically meant to handle it, it can be simulated to an extent.

Here, a simple hack that boosts the aerosol density below a given height:


There are some disturbing effects on the boundary during the movement though, and it would probably have to be implemented in a different way because fog particles have slightly different properties than normal non-condensing aerosol particles in the air.

Yes, the fog does look very nice.  But as Brano said, more work will have to be done.  And welcome to the Outerra community yoonsikp. :)

The fog does look great- No flightsim i've played has ever got it 'right' (i.e. wispy, variable density etc).....but that looks fantastic!

For a quick hack that fog looks incredible.

Simply brilliant, if this is the result of a "quick hack" then I cant wait to see how the atmospheric generator part of it will look. Creating realistic atmospherics has never been done by any current flight sim, they all have settled for static balls of cotton wool and fixed backdrop imagery.
Given that weather computation can only be performed on "super computers" I would be most interested to know what approach you will take to generate a spectacular cloudscape, the dynamics of the atmosphere and "reading clouds" is fudamental to a great many aviation activities, weather effects and so on all play a part.
