43 
44             This 3D grouping primitive is used to define a shadow for
45             3d geometry by embedding it. The shadow of 3D objects are
46             2D polygons, so the shadow transformation is a 2D transformation.
47 
48             If the Shadow3D flag is set, the shadow definition has to be
49             combined with the scene and camera definition to create the correct
50             projected shadow 2D-Polygons.
