+            Baseclass for all grouping 3D primitives
+
+            The description/functionality is identical with the 2D case in groupprimitive2d.hxx,
+            please see there for detailed information.
+
+            Current Basic 3D StatePrimitives are:
+
+            - ModifiedColorPrimitive3D (for a stack of color modifications)
+            - ShadowPrimitive3D (for 3D objects with shadow; this is a special case
+              since the shadow of a 3D primitive is a 2D primitive set)
+            - TexturePrimitive3D (with the following variations)
+                - GradientTexturePrimitive3D (for 3D gradient fill)
+                - BitmapTexturePrimitive3D (for 3D Bitmap fill)
+                - TransparenceTexturePrimitive3D (for 3D transparence)
+                - HatchTexturePrimitive3D (for 3D hatch fill)
+            - TransformPrimitive3D (for a transformation stack)
