If the camera moves so that there is enough parallax between the views, then the 3D shape of the surface can be recovered. Using a dense set of matched points from the correspondence optimizer, a structure from motion algorithm recovers the camera position as well as an accurate estimate of the location of close to a million different points on the surface. These points are used with one of the views to produce a 3D texture mapped model which can be viewed in the appropriate visualization tools.
