The thought struck me too, but I have so little expirience with such things
you know.

There are several other things that I find odd, too. Such as: What's the
difference between:

    #declare Tooth = function { niceonehere }
    isosurface { Tooth(x, y, z) }

and

    #declare Tooth = function { niceonehere }
    isosurface { Tooth }

Another one:

isosurface {
        function {
                Tooth(x, y, z) + 0*SomeDistortion(x, y, z)
        }
}
versus:

isosurface {
        function {
                Tooth(x, y, z) //+ 0*SomeDistortion(x, y, z)
        }
}

(see my other post.)

So: I wonder if there exists some extensive documentation on Isosurfaces?
Are there bug fixes? Should we send reports to NathanKopp? Someone else?

5k.
