See the thread in this newsgroup entitled "Superpatch built-in functions"
from 15 July.  Here are the relevant headers for the first article:

In case you can't look it up (but you should, because it's a useful
thread) here's the syntax that works for me for the sphere function:

isosurface {  function { "Sphere" <1> }  pigment { color red 1}}

Most of my docs were written by the people who wrote the original docs for
the patches I included, though I tried to make sure the syntax was spelled
out.  This particular case resulted from an oversight in copying R. Suzuki's
original documentation.  I'm no longer maintaining the superpatch, but if
someone wanted to write better docs for various parts of it, I'm sure Nathan 
would gladly accept them.
