A -surface half-space is the region whose points satisfy a positive of negative +surface half-space is the region whose points satisfy a positive or negative inequality of the surface equation. For example, for a sphere of radius one centered at the origin, the surface equation is :math:`f(x,y,z) = x^2 + y^2 + z^2 - 1 = 0`. Thus, we say that the negative half-space of the sphere, is
