You don't need an algebraic function, you can use patterns as functions, 
and there is a density_file pattern. If you can translate your data to 
the .df3 file format (which is described in the documentation), you can 
put it in a pattern function and use it in an isosurface object.

The image on that page you gave would be generated using an isosurface 
and some kind of square (a very thin box, two triangles, a polygon, a 
clipped plane...whatever) with the same function used as a pattern for 
the texture.

That "equpotsurface" is just a very (VERY!) old version of the 
isosurface patch. It is quite obsolete.
