  abstract = {Generating object silhouettes lies at the heart of nonphotorealism
              and is needed for many styles of rendering. This article
              describes, categorizes, discusses, and recommends algorithms for
              computing the silhouette of a polygonal model, thus guiding
              developers to the optimal approach for their specific needs.},
