We present a novel method for interactive retrieval of virtual 3D shapes using physical objects. Our method is based on simple physical 3D interaction with a set of tangible blocks. As the user connects blocks, the system automatically recognizes the shape of the constructed physical structure and picks similar 3D virtual shapes from a preset model database, in real time. Our system fully supports interactive retrieval of 3D virtual models in an extremely simple fashion, which is completely
