Can anyone give me a list of the types of density_maps that exist in POV?
(specifically for use with media)?
I know spherical, cyllindrical, and onion - what am i missing?
Thanks,
OpalPlanet

You can use any pattern as a density map. It's no different from using
patterns with color maps, pigment maps, texture maps, etc.

that's what I thought, but when I use gradient I get an error -
density{
gradient density_map{
[0 rgb 0]
[.5 rgb 1]
[1 rgb 0]
}//end map
scale 5
warp{turbulence 20}
}
???

Because gradient requires a parameter: The direction vector.

Have you tried
density{gradient y density_map{...}}?
