[coming back to this earlier discussion]
Using Gilles Tran's application makedf3object.pov this is much faster in
my experience. Fifteen minutes per channel or so...

Yes, that is interesting but quite different from a media.

You can use just a single df3 with a layer of three different density
maps, each dedicated to one of the RGBs. The DF3 is the "container".
