Figure 10.

Relative depth of 1-D and 2-D stimuli. (A) 1-D stimulus pairs (Gabors), shown with disparity vectors. The disparity constraint line of one stimulus appears on the left and that of the other stimulus appears on the right. Each constraint line exceeds the disparity magnitude of the other stimulus, indicating that IOC provides an inconsistent relative disparity. (B) A 1-D stimulus (Gabor) and a 2-D stimulus (plaid) with constraint and projection lines giving consistent relative disparity measures. (C) A pair of 2-D stimuli (plaids) with unequal horizontal disparities (left) and with the same disparity amplitudes after rotation of one disparity (center) has reversed the relative horizontal disparities. The same non-parallel disparities from plaids with differing orientations can be compared along the RDA, restoring the original relative disparity ordering (right).
