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{...}}?
