// Class : PhysxPlaneShape
// Description : A plane collision detection primitive. By default
// it is configured to be the y == 0 plane. You can
// then set a normal and a d to specify an arbitrary
// plane. d is the distance of the plane from the
// origin along the normal, assuming the normal is
// normalized. Thus the plane equation is:
// normal.x * X + normal.y * Y + normal.z * Z = d
//
// Note: the plane does not represent an infinitely
// thin object, but rather a completely solid
// negative half space (all points p for which
// normal.dot(p) - d < 0 are inside the solid region.)
//
// Each shape is owned by an actor that it is attached
// to.
//
// An instance can be created by calling the
// createShape() method of the PhysxActor object that
// should own it, with a PhysxPlaneShapeDesc object as
// the parameter, or by adding the shape descriptor
// into the PhysxActorDesc class before creating the
// actor.
//
// The shape is deleted by calling release() on the
// shape itself.
