        /** ShadowPrimitive3D class

            This 3D grouping primitive is used to define a shadow for
            3d geometry by embedding it. The shadow of 3D objects are
            2D polygons, so the shadow transformation is a 2D transformation.

            If the Shadow3D flag is set, the shadow definition has to be
            combined with the scene and camera definition to create the correct
            projected shadow 2D-Polygons.
