This presentation updates progress and new developments in the integrated system for storage, archiving, sketch-based query and retrieval system of three-dimensional (3D) objects developed under a NSF KDI grant at Arizona State University. The project has developed software to model surfaces of 3D objects from scanned point cloud data and to automatically extract features and identify regions of interest identified as meaningful by discipline researchers. The Web-accessible visual query interface permits users to define searches with both contextual and spatial criteria, search the databases and retrieve matching objects. The interface currently supports query input via 2D sketches, and support for full 3D interactive models is under development. The interface displays textual and metric descriptive data and interactive 2D and 3D models that permit researchers to explore and interact with object models.
Project content includes Native American ceramic vessels, bone surfaces (anthropological, and forensic applications), and cellular DNA structures. Symmetry and spatial comparison of other 3D data is in process including brain shape, facial recognition, and cloud formation. The Partnership for Research in Spatial Modeling (PRISM) team is exploring extendable models for digital libraries of 3D data that capture, model, extract meaningful features, and automatically catalogue data, and interfaces that permit researchers to search and identify similar objects, then retrieve, compare and interact with models of the complex 3D data.
