+#  Filename : multiple_parameterization.py
+#  Author   : Stephane Grabli
+#  Date     : 04/08/2005
+#  Purpose  : The thickness and the color of the strokes vary continuously 
+#             independently from occlusions although only
+#             visible lines are actually drawn. This is equivalent
+#             to assigning the thickness using a parameterization covering
+#             the complete silhouette (visible+invisible) and drawing
+#             the strokes using a second parameterization that only
+#             covers the visible portions.
