    <dd>compute the Voronoi diagram by computing the Delaunay
        triangulation.    Use option '<a href="qh-optq.htm#Qbb">Qbb</a>'
        to scale the paraboloid and improve numeric precision.

    <dd>compute the halfspace intersection about a point via polar
        duality.  The point is below the hyperplane that defines the halfspace.
