Five experiments demonstrated that adults can identify certain novel views of 3-dimensional model objects on the basis of knowledge of a single perspective. Geometrically irregular contour (wire) and surface (clay) objects and geometrically regular surface (pipe) objects were accurately recognized when rotated 180 about the vertical (y) axis. However, recognition accuracy was poor for all types of objects when rotated around the y-axis by 90. Likewise, more subtle rotations in depth (ie, 30 and 60) induced decreases in recognition of both contour and surface objects. These results suggest that accurate recognition of objects rotated in depth by 180 may be achieved through use of information in objects'2-dimensional bounding contours, the shapes of which remain invariant over flips in depth. Consistent with this interpretation, a final study showed that even slight rotations away from 180 cause precipitous drops in recognition accuracy.
