Paper Abstract

We have conducted experiments in which subjects are asked to make judgments about the shape of graphically rendered, rotating convex objects. As compared with monoscopic display, stereographic display enhances the subjective clarity of object shape. There are two obvious candidates for the source of this enhancement. One possibility is that the occluding contour is seen as a rotating 3D outline, providing greater object stability, and therefore better cues to the overall shape. Another possibility is that patches of the shaded surface may be perceived in depth, providing a clearer perception of the local surface curvature, and therefore a better sense of the overall shape. In this paper we present an empirical examination of the effects of including stereopsis in the task of shape understanding, and we isolate and compare these two possible explanations.
