Abstract. A qualitative model for describing 3D objects (Q3D) using depth and different perspectives is presented in this paper. The front, right and up perspectives are considered as canonical. The Q3D model allow reasoning through logics defined to test the consistency of descriptions. The maximal volume of the object is also obtained logically using its Q3D description. Moreover, this model infers some features of the unknown perspectives of the object by defining logics based on the continuity of holes and the relative depth presented by opposite perspectives. The Q3D logics are implemented in Prolog and promising results are obtained, which can inspire approaches to solve 3D spatial problems computationally.
