It's really pretty simple, I don't mind sharing the code now because this is
very early WIP stuff. Here's the bit that does the atmosphere, I've
simplified it a little but it should look about the same:
//planet
sphere { 0, 6000 }
//atmos
difference {
sphere { 0, 6050 }
sphere { 0, 6000 }
hollow on
pigment { rgbt 1 }
interior {
media {
scattering {
1, rgb <.05,.17,1>
extinction 1
}
density {
function { exp( -(sqrt(x*x+y*y+z*z)-6000)/4 ) }
density_map {
[0 rgb 0]
[1 rgb .1]
}
}
}
