We examined applicability of the generic-view principle to the extraction of structure from motion. In particular we manipulated the angle between the line of sight and the rotation axis of the spherical surface that was defined by moving paired or unpaired random dots. The image motions of the sphere were categorized using an aspect graph and assigned values of genericness/accidentalness. The generic image motions elicited clearer/more depth than the accidental ones in the paired-dot stimuli, being mostly consistent with the predictions of the generic-view principle. The effect of the generic image motion was less in the unpaired-dot stimuli than in the paired-dot stimuli. It is suggested that the combination of the generic-view principle and the relative-motion hypothesis could better explain perception of the rotating sphere in general. Thus, both of them seem to contribute to the processing of structure from motion.
