Figure 2.

Anaglyph versions of the stimuli used in the experiment. Horizontal/vertical corrugations. The left anaglyph presents a vertical sinusoidal corrugation. The right anaglyph corresponds to a horizontal sinusoidal corrugation (for correct viewing, place the red filter in front of the left eye). The spatial frequency at the correct distance is 0.1 cycles/deg. The panels with the lines represent the disparities shown in the anaglyphs. The corresponding 3D representations are shown in the top right part of the figure. Note that this figure is for illustration purpose only, for example, the dot density is lower than the stimuli used in the experiments. Figure adapted from.¹³
