Predicted 1-D/2-D depth matches. (A–D) The disparity vector of a 2-D stimulus is represented by a magenta arrow. The disparity vector of a 1-D stimulus that produces a perceptual depth match according to the IOC construction is represented by a blue arrow. The thick line shows the orientation of the 1-D stimulus, the thin line is the perpendicular orientation, and the dashed line is the disparity constraint line. All predicted relative disparities except (D) agree with experimentally observed values. (E) Superimposed disparity vectors of the 1-D stimuli, shown scaled up, reproduce the disparity vector of the 2-D stimulus, similarly scaled, as an IOC result. The depth-matching 1-D disparities therefore would be component disparities of the 2-D stimulus.
