A circular cylinder defined by binocular disparity appears flattened at a far distance. It is assumed that the subject estimates the 3D shape using a distorted perception of the physical viewing distance. If the inaccurate distance causes the shape distortion, the estimated lengths for both height and depth would be shorter than the actual lengths. Here, we investigated whether the inaccurate distance could completely account for the flattened perception, estimating the depth and height of the cylinder separately. The results proved that the inaccurate distance does not account for the flattened perception. Instead, the viewing distance affects only the depth perception. Moreover, the following experiment indicated that adding texture and shading cues to the binocular cues does not change the characteristics of the binocular cues only.
