  abstract = {Nonphotorealistic rendering (NPR) can help make comprehensible but
              simple pictures of complicated objects by employing an economy of
              line. But current nonphotorealistic rendering is primarily a batch
              process. This paper presents a real-time nonphotorealistic
              renderer that deliberately trades accuracy and detail for speed.
              Our renderer uses a method for determining visible lines and
              surfaces which is a modification of Appel's hidden-line algorithm,
              with improvements which are based on the topology of singular maps
              of a surface into the plane. The method we describe for
              determining visibility has the potential to be used in any NPR
              system that requires a description of visible lines or surfaces in
              the scene. The major contribution of this paper is thus to
              describe a tool which can significantly improve the performance of
              these systems. We demonstrate the system with several
              nonphotorealistic rendering styles, all of which operate on
              complex models at interactive frame rates.},
