线条画可以用非常少的视觉内容来传达形状。暗示性轮廓是在某些类型的与视图相关的表面拐点处绘制的线条，最近被提出作为提高计算机生成线条画有效性的一种方法。本文扩展了以前的工作静态暗示轮廓动态和实时设置。我们分析运动的提示轮廓的变化，在视点，并提供技术，提高质量的中风呈现为一个移动的相机。我们描述了实用的算法，绘制的轮廓和暗示性的轮廓在互动的速度。最后，我们讨论了在静态和动态的情况下，用于改善暗示性轮廓的视觉外观的技术。
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.
