+            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.
