I've looked at Kevin Loney's approximation macro and Jaap Frank's go-
faster version for my Isosurface tutorial. Note that for many
isosurfaces it is faster to render the isosurface than it is to use the
approximation.

For parametric isosurfaces, there's Ingo Janssen's param.inc, which has
the advantage of being considerably faster than the original isosurface.

See my <http://www.econym.demon.co.uk/isotut/> for details.
