You really can't put an isosurface to a wireframe.  You could create
approximations using an algorithm such as the marching cubes algorithm, but
it wouldn't be perfect.

I was once working on a macro that approximated an isosurface using a slight
variant of the marching cubes algorithm, but never quite finished it.
Parsing would take an extremely long time, especially if you wanted it to be
really accurate.  But the result would render very quickly compared to the
original isosurface.
