  abstract = {We present a new algorithm for rendering silhouette outlines of 3D
              polygonal meshes with stylized strokes. Rather than use silhouette
              edges of the model directly as the basis for drawing strokes, we
              first process the edges in image space to create long, connected
              paths corresponding to visible portions of silhouettes. The
              resulting paths have the precision of object-space edges, but
              avoid the unwanted zig-zagging and inconsistent visibility of raw
              silhouette edges. Our hybrid screen/object space approach thus
              allows us to apply stylizations to strokes that follow the visual
              silhouettes of an object. We describe details of our OpenGL-based
              stylized strokes that can resemble natural media, but render at
              interactive rates. We demonstrate our technique with the
              accompanying still images and animations rendered with our
              technique.},
