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.
