Hi again! (Maybe I should move to noob forum...)
Well, I tried to do dust by adding density statement to
media/scattering. I did:
box {
<-100,-100,-100>, <100,100,100>
pigment {checker rgb 1, rgb 0}
interior {
media {
scattering {
1, rgb 0.2
}
density {
bozo
}
}
}
hollow
}
It didn't work as expected: the dust had all kinds of colors, not gray.
Manual states that bozo has a built in color map so does density also
have components for different color components (red, green blue)? What
is the proper way to have the same density for all color components? The
next worked but is there a better way to only define that bozo gives the
same value for red, green and blue?
density_map {
[0.0 rgb 0]
[1.0 rgb 1]
}
PS. Never mind the actual result, I removed all the scaling and
unimportant stuff...

IIRC you need to specify a color map for bozo - something like
density {
bozo
color_map{
[0 White]
[1 Black]
}
}
Also, iirc, one of the other patterns is identical to bozo, but doesn't have the
assoc. color map problem - spotted or leopard iirc.

Outside of a normal, bozo, bumps, and spotted are identical. Inside a
normal, bumps is a bit different, using its own method for perturbing
normals.

It does. This is what allows you to specify varying colors for the media.

The method you used, specifying a black-white density map, is the right
way to do it.
