how about some new atmosphere feature?

[Verz Veraldi]

Well, you see, Celestia have a lot of great feature like atmospheric scattering, specular, bump, and whatever you ask...
So I've been editing atmosphere with mie and rayleigh algorithm alot, so it's been very familiar editing those.. Until I discover something interesting that some of you might know....

How about in Celestia?

Back to topic, so what I'm trying to tell is, how about adding like 'atmosphere density' or 'mie density' ? I'm not complaining to what celestia have now but it looks alot more realistic than celestia now. I have one question anyway, in the ssc files, some are written 'hazedensity' which is used to add colorized haze to the planet WITH the nvidiaCombiner render path, not opengl 2.0 nor others.. is there any way to have those effect WITH the opengl 2.0 render path but still having the mie effect?

It's always a good idea to use the resident search engine (or Google) first. In this thread (Atmospheric Scattering Revisited) we have also discussed Bruneton's approach at length among Mie experts.

Further below in that thread I have also listed quite a large number of Bruneton's stunning videos about the matter. Chris has presented some new code for improved (precomputed) atmosphere rendering a la Mie/Bruneton in this thread. You can play with the code patch if you please.

With 121715 shatters net posts the chances are high that the relevant things have been discussed already.

I didn't seem to find the patch on the forum... where is it? should I pm chris?

I guess Chris sent it to me personally some time ago. So if you are able to compile Celestia yourself, you best contact him via PM. Perhaps he has meanwhile written some more code.
