Hey guys, I'm looking for a function or pigment function that creates a single
bump when added to an isosurface.  I've been tinkering with the spherical
pigment but of course that adds or subtracts a full hemisphere of a sphere onto
the surface.  Is there a way to modify this pigment or is there another function
that creates a more bump like feature where the protrusion smoothly blends into
the underlying surface?  I'd like a single occurence of the pattern because I'd
like to control the placement of it, and I've been trying to avoid multiplying
sphere functions together to create a blob like effect because it kills the
rendering time and alters my surface in too many ways.  Any suggestions would
be appreciated.
