I think there is an algorithm called "marching cubes" which might be 
sufficient. I believe it is commonly used in metaball 
modellers/renderers which don't do render directly like POV does.

I don't actually know anything about this "marching cubes" algorithm, 
but the name alone gives me some ideas...I don't think it would be an 
easy feature to implement in POV though. Maybe in 4.0...
