I'm playing around with rearranging them myself now, if it
doesn't turn out well I'll try your variation...or I could
do both. ;)
> Is the the wheel of constant depth and are the media of uniform densities?
Yes. The wheel is a cylinder with radius of 4 height 1 at 0,0,0,
the media having only the properties of scattering, emission, and/or
absorption with rgb values -0.5, 0.0, or 0.5.
> How is the light located?
The scattered light is located at 0,0,0.5 with fade distance of 1.0
and fade power of 2.0. There is an additional non-scattering light
at 0,0,20 to provide ambient illumination, with fade distance of 0
and fade power of 1.
> Is the wheel in front of (over) the spheres?
The dot/lines are located 0.5 units over the origin at a distance
of 3.5 units. The coloured spheres lie at z=0.
> Where do the glows come?
The scattering light is the only light source affected by media,
all glows are properties of the media through which the light is
travelling.
> Is there media outside the wheel?
No.
