Volume perception, that is, perception of a partially enclosed space filled with a medium, can be assessed not only from binocular viewing but also from motion. We studied the volume perception of a cylindrical object in motion. The motion (rotation, translation, or rolling) of the cylindrical object was simulated with and without appearing and disappearing parts (ADPs). We found that volume perception could be assessed easily with ADPs but was difficult without ADPs. These experimental results indicate that ADPs are an essential factor for volume perception from motion, which is correspond to binocularly unpaired regions for volume perception in binocular viewing.
