Abstract

This paper presents an XML-based graphic database system for 3D graphic data. We describe a 3D database system supporting semantics of 3D objects and content-based retrievals. The data model underlying the 3D graphic database system represents 3D scenes using domain objects and their spatial relations. An XML-based data modeling language called 3DGML has been designed to support the data model. It offers an object-oriented 3D image modeling mechanism that separates low-level implementation details of 3D objects from their semantic roles in a 3D scene. The user can pose a visual query based on the contents of 3D images including 3D shapes and spatial relations. The query based on the shapes of 3D objects retrieves 3D images containing objects of similar shapes to a given object. The similarity of objects is determined by comparing their contours. We believe our work is one of the earliest efforts to support content-based retrieval for 3D graphic images.
