Abstract:
Line drawings can convey shape using remarkably minimal visual content. Suggestive contours, which are lines drawn at certain types of view-dependent surface inflections, were proposed recently as a way of improving the effectiveness of computer-generated line drawings. This paper extends previous work on static suggestive contours to dynamic and real-time settings. We analyze movement of suggestive contours with respect to changes in viewpoint, and offer techniques for improving the quality of strokes rendered for a moving camera. We describe practical algorithms for rendering drawings with contours and suggestive contours at interactive rates. Finally, we discuss techniques for improving the visual appearance of suggestive contours, in both the static and dynamic cases.
