Yes...I suppose it would.
A 3df is a 3D Density File, sort of a 3D bitmap.(which I guess would 
make POV a 3D vector format) Instead of storing polygons or other 
shapes, it stores voxels, the 3D equivalent of a pixel.
POV has the ability to read these files as a pattern, so you can use 
them as input for an isosurface. It also has interpolation features 
which make lower-resolution 3df files useable.

I am currently working on a Mac modeller for 3df files...I thought this 
might be a useful feature for it. The only real problem would be the 
size of the  file...though it would at least be smoother than a height 
field, and could have things like caves.
