Yeah, I've thought about doing something like that. I could also have good use of the sRGB texture reads and writes, though that's not exposed in OpenGL. The non-linearity of the framebuffer makes details in the background become more apparent when you add something on top of it.

OT but..

Look at the last 3 pages of this thread.

What about my understanding of how Developers deal with DX9 shaders. They dont Write the shader with a specific Percision in mind right?? they write it in Dx9 HLSL and the Driver and hardware deal with the rest.

You dont write an FP16 Shader and a Fp24 shader and a FP32 shader.. You srite a Shader and the Drivers Interpret that and deal with it internally correct??

OpenGL is of course different...

I appriciate your time.

Nice job Humus !

Thinking of any specific IHV here ? :P

Hey Humus. As always, nice demo!

I hope you don't mind some constructive criticism

One thing I noticed is that it's very dark in the corners of the room. I can just barely see them on my monitor, unless I have a light between me and a dark corner. If this were real, having a bright glaring light between me and a dark object wouldn't help me to see it...just the opposite in fact. The same atmospheric haze that's scattering the light towards the viewer will also diminish the amount of light reaching the viewer from the bakground.

I haven't looked at your shader, but I assume the final per pixel color is done something like this:

final color = backgroundColor + lightColor * lightVolumeThickness

When it should probably be more like this:

final color = (1-lightVolumeThickness) * backgroundColor + lightColor * lightVolumeThickness

Of course, a real atmosphere would probably exhibit more of an exponential decay than a linear one, but I think this would be a simple way to make it much more realistic.

Dear Humus,
can I become a Co-worker on your [H] equivalent site? Your new site, as you describe it, is a lot better than the original [H]ardocp site, so I quit at [H]ardocp and now I want to work with you.
