Off the top of my head, POV-Ray's media would get approximated by a procedural
function that governed the rgb values based on the <x, y, z> coordinates, and so
whatever method that threejs uses, or Shadertoy ought to give decent results.

Reading in a df3 file would seem to be the only bottleneck.

Are you looking to make it faster than the examples you linked to?
Or are you looking to find a way to render 3D volumes in POV-Ray faster than
whatever methods you're currently using?
