通过对以随机点立体图表示的圆柱形连续曲面形状的判断，研究了视差信息在确定三维形状中的有效性。 在近距离观察时，真正的圆柱体看起来是细长的;在中等距离观察时，感觉接近真实;在远距离观察时，圆柱体看起来是扁平的。 根据这些数据计算了缩放距离的间接测量值。 结果强烈表明，所观察到的形状失真的结果缩放水平的差距与自我中心的距离不正确的措施。
The effectiveness of disparity information in defining 3-D shape was investigated by means of judgments of the shape of cylindrical continuous curved surfaces presented as random dot stereograms. At a close viewing distance, truly circular cylinders appeared elongated; at an intermediate distance, perception was close to veridical; and, at a far distance, cylinders appeared flattened. Indirect measures of scaling distance were calculated from these data. The results strongly suggest that the observed shape distortions are a consequence of scaling horizontal disparities with an incorrect measure of egocentric distance.
