Abstract:
There have been several papers on pseudo-3D representations that can represent 3D scenes without using full 3D geometry, such as polygons ([Cohen et al. 2000], [Bourguignon et al. 2001]). This paper presents a new pseudo-3D representation and its rendering algorithm for producing cartoon-like illustrations, which tolerates changes in viewpoint/viewing angle. Cartoon-like illustrations emphasize outlines, which are drawn in thick, dark lines. In our representation, the target 3D objects are represented as outlines only, not as full 3D geometries. These outlines of the illustration are located in 3D space, not on a 2D plane. We call this 3D curve the 3D outline. Our 3D outline representation is intermediate between typical 3D representations and 2D illustrations. Although this model contains limited 3D information, we can view and rotate the illustration as if there were full 3D geometry. (Figure 1)
We have implemented a prototype system, SilF, for viewing and editing 3D outlines with a 2D-like sketching interface using standard 2D input devices.
