... unless you are using a sor. :)

Actually, I have had problems with sor, so actually did use a lathe for
my baseball bat.

But back to the spherical_sweep -- one of the issues with the sweep is sometimes
the spline takes non-obvious paths to connect the points, so a little care
is needed in specifying the control points.  Nevertheless, it is a wonderful
primitive, and certainly would be justified for inclusion into "standard" POV.
