I found this utility for creating and viewing df3s. It uses OpenGl to 
view it.
It can create df3s from pngs and mesh-ify df3s. It calls it Isosurface 
and exports a mesh.
It was written with PovRay in mind and for medical use. So we are 
talking animations. It creates df3s from one colour channel of a series 
of images. So they can be separated.
All in all it is worth a look if you are working on df3s.

Not all is rosy, the help file is in Japanese but there is an English 
document on the download site. The Iso-Mesh has a couple of problems. It 
exports the decimal separator as ÷ and has trailing commas in lists. 
Easily fixed. (Latest Windows version.)

Hey!  This looks like fun.   I will give it a look in the near future.
The Dragon is looking much better - I like the colors.

The fun part is using a help file in Japanese. ;)
I've updated the last dragon image with a higher resolution df3.
I will write a "how to" when I work out how I created a colour map.
The program is quite intuitive but there are some things that are hidden.
