Abstract:Content-based 3D model retrieval is becoming the hotspot. The diversity of the way in which the 3D model is described makes it very difficult to retrieve 3D model in Internet. Describing the 3D model in XML can solve the difficulty effectively. The content-based retrieval technology o.f 3D model described in XML is discussed. After introducing the principle and the system framework of the 3D mode retrieval, the primary key techniques of content-based 3D model retrieval are analyzed, including the data structure, the way of describing the 3D model in XML, the normalization by preprocessing, the feature extraction, the building of index, the similarity measurement and the design of user interface.
Keywords:XML  content-based 3D model retrieval  preprocessing  feature extraction  index
