...and also why can't 3D world model be just described abstractly, by presenting the intelligent agent with bunch of objects with attached properties and relations between them that preserve certain invariants? Spacial part of world model doesn't seem to be more complex than general problem of knowledge arrangement, when you have to keep track of all kinds of properties that should (and shouldn't) be derived for given scene.
