Nope not quite Gauss Maps are used by Gooch. Zhang uses something similair a normal mask as rectangular cells and clustering. I think Gauss Maps don't work correct with backface culling which was the primary target for Zhang. > Also, there are some smart seeding strategies using local coherence > for classifying silhouette edges efficiently.

But you don't get edge data itself if you need it.
