3D model retrieval with point-sampled representation using functional and geometrical aspects

We describe a novel system that achieves intuitive retrieval of 3D meshes from a database of 3D models based on the shape geometry and its functionality. By using a point-sampled representation of a 3D shape both for a query and models, our system allows user to physically and interactively express a geometrical and content-based query by simply assembling a set of ActiveCubes. The user can retrieve 3D models from the database based on their shape and can physically integrate functional annotated blocks in the query. The user intuitively defines an interactive spatial query that has geometrical and functional aspects.
