Content-based 3D graphic information retrieval

Supporting the content-based retrieval of 3D graphic data has been little addressed in the most current 3D graphic systems. The systems focus on visualizing 3D images. This paper presents a 3D graphic data model which models 3D scenes using domain objects and their spatial relations. The model also supports the content-based query. The user can pose a visual query involving various 3D graphic features such as an inclusion of a given object, object's shape, descriptive information, and spatial relations on the web interface. We discuss the 3D data modeling technique and content-based retrieval in detail.
