Vertical-disparity gradients are processed independently in different depth planes

By P. A. Duke and I. P. Howard

Abstract

We examined the effects of vertical-disparity gradients on apparent depth curvature of textured surfaces. In Experiment 1, vertical disparities induced expected curvatures when the surface had a horizontal disparity of < ±40.34′. A central row of elements, lacking vertical disparities, ceased to have the same apparent curvature as the surface when the horizontal disparity between row and surface exceeded ±5′. In Experiment 2, vertical disparities were not pooled between superimposed surfaces separated by horizontal disparities > ±10′. Thus, vertical-disparity gradients are not pooled over depth for curvature perception. Our results suggest that vertical disparities are used to determine distances to surfaces directly, rather than to estimate vergence
