No worries.  I tend to find myself in the deep end of the pool a lot.  :D

The trick there is that since it's a discontinuous function with an infinite
gradient, one just inserts a user-made smooth gradient to join up the 2 regions
of the function.  And then the isosurface method that you want to use works just
fine.
