Paper Abstract

Brunelleschi (1413) was the first to demonstrate that a 3D scene can be represented by a 2D perspective picture in such a way that retinal images produced by the scene and the picture are identical (subsequently, Leonardo pointed out that this is true only when the observer's eye is placed at the center of perspectivity that was used to produce this picture). It follows that in the absence of depth cues, the percepts are identical as well. A question arises as to the effect on the percept of viewing the picture from a point different from the center of perspectivity. According to Pirenne's (1970) theory, the percept involves taking the cues to the orientation and position of the picture relative to the observer into account, in order to compensate for the incorrect viewing point; when these cues are available, the percept is accurate. We will demonstrate a new visual phenomenon called `cuboid illusion' which contradicts Pirenne's theory. Our experimental results show that the percept of a 3D object from its picture systematically depends on the orientation and position of the picture relative to the observer even in the presence of many cues.
