i am trying to create an atmosphere around my planet.
Currently its just a transparent Sphere which is a bit bigger than my earth. But it dosen’t look really good.
I want somehting like the following:
How can i do that?
Can i create fog around the planet or maybe a strong bloomeffect only for the earth ?
I am sure this question has come up before, but i couldn’t find anything in the forum.
Not that much help, but I think you’re the first actually 
We do have a bloom effect… there’s some tests in the jmetest package for it (just search for bloom). Not sure you should “bloom” your earth itself though, since you’ll probably want a more uniform color for your “blooming” than something based on the earth texture.
i knew it, how could i possibly miss that post

Id suggest going the Rayleigh and Mie scattering GLSL (shader) way for optimal effect. I've read a couple of papers on these scattering methods and they blew my head away. So be careful.
it looks really nice with shaders and stuff, but i am afraid thats a bit too advanced for me right now.
i have to fix some more basic things first
but i will look into it if i have some spare time.
