marr's 2.5d sketch assumes that a depth map is constructed, and that this map is the basis of 3d shape perception. however, both stereoscopic and pictorial perception, as well as monocular viewing, make clear that the perception of 3d shape precedes, and does not rely on, the perception of the depth of points. it is not clear how a preliminary depth map could, in principle, be constructed, nor how this would address the question of figure-ground organization, or grouping. the role of perceptual organizing constraints, overlooked by marr, in the production of 3d shape percepts from binocularly-viewed 3d objects has been demonstrated empirically for the case of 3d wire objects, e.g. for a more detailed discussion, see pizlo (2008).
