Can somebody can help me to simulate an "Atmospheric blue media" like
Terragen does (for example) this test scene following use the fog to
simulate it but I think I can does it better with medias... the fog is too
simple and the far spheres looks to be erased by the fog, I just want to
make them blue-er like when you look at far mountains at the morning...
// MEDIA test... without media so !
background {color rgb <0.1, 0.1, 0.8>}
light_source {<30, -30, 100> color rgb <1.0, 1.0, 0.9>
area_light <-10,-10,-10><10,10,10>,5,5
adaptive 2
jitter
circular
orient
}
plane {z,0 texture {pigment {color rgb <1.0, 1.0, 0.9>}}}
camera {location <0, 0, 1.7> look_at <0.0, 50.0, 1.0>}
#declare yy = 0;
#while (yy < 31)
sphere {<3, yy*8, 1>1 pigment {color rgb <0.7, 0.1, 0.2>}}
sphere {<-3, yy*8, 1>1 pigment {color rgb <0.7, 0.1, 0.2>}}
#declare yy = yy + 1;
#end
fog {
fog_type 1
distance 150
color rgb <0.5, 0.5, 0.8>
}

Have you tried filtering fog?

I try scattering media, but I can't tune it ! my blue sky become black an no
media appear...

Remember that light gets scattered more when it passes through more
media. Also, I've found extinction 0.1 to be a good value for
atmospheric media. Don't use isotropic scattering, Rayleigh seems best
fit for the purpose. Lastly, before you venture into media, I still
think the effect you're after can be achieved by adding filter or
transmit to the color of your fog, without any media whatsoever.
