//
//	The Imath::Plane3<> class represents a half space, so the
//	normal may point either towards or away from origin.  The
//	plane P can be represented by Imath::Plane3 as either p or -p
//	corresponding to the two half-spaces on either side of the
//	plane. Any function which computes a distance will return
//	either negative or positive values for the distance indicating
//	which half-space the point is in. Note that reflection, and
//	intersection functions will operate as expected.
