No, just the opposite. What it's really saying is that <0,0,0> has no
density at all, equivalent to rgbf <1,1,1,1> in a halo. And so rgb 1 is
actually a unit of media density, or saturation, although any real number
can be used.
The main difference being that filtered or transmitted color is null and
void when tried in media.
I looked at your scene again and found that the ior and caustics when used
the 3.1 way, in a interior statement, all is fine with the glass and shadow.
#declare Glass =
material {
texture {
pigment { color rgbf <0.98, 0.98, 0.98, 0.9> }
finish {
ambient 0.1
diffuse 0.1
reflection 0.1
specular 0.8
roughness 0.003
phong 1
phong_size 400
}
}
interior {
ior 1.45
caustics 1.0
}
}
Then apply it as material {Glass} instead of only texture {Glass}.
I also tried adding absorption <0,0,1>*.25 in the media as well as lowering
both the emission and density D variable. It's all a matter of tweaks, I
don't know of any straight conversion.
Oh, and to get rid of the faint artifact crossing left to right on the back
wall put the keyword sturm into your quartic.
