Abstract:
Techniques for automated rendering of 3D models using sparse line drawing styles, for applications ranging from illustration through cartoons and games. The course introduces concepts of visual perception; defines silhouettes, contours, creases, and suggestive contours; describes efficient algorithms for finding these lines; and presents methods for artistic stylization.
