Zusammenfassung
Perceived three-dimensional shape can be systematically distorted by altering viewing conditions. Here we investigate whether such distortions are inconsistent or congruent among different surface properties (relative depth, orientation, and curvature). Participants matched two surfaces defined by different types of visual information (motion parallax, texture, or shading). Judgments of different surface properties elicited qualitatively different patterns of distortions. Adding multiple sources of information did not eliminate inconsistencies. This result indicates that 3D shape perception is not based on Euclidean representation. Moreover, models of cue integration that assume interpretation of information prior to fusion cannot account for such findings.
