Hi J.D. I think the Zhang et al. paper that you're referring to is the one that is based on Gauss Maps. I was planning on doing something with too.
Also, there are some smart seeding strategies using local coherence for classifying silhouette edges efficiently. But as I said, silhouettes are beasts compared to crease edges, boundary edges etc., and the software approach can sometimes produce wrong effects, for example, if the polygonal edges are not exactly aligned. This is the reason why I sounded a wee bit hesitant about suggesting a solution for the curved surface of the cylinder.
