Recent advancements in digital archiving technologies have enabled us to store greater amounts of priceless digital data related to cultural properties. However, accessing this information by using conventional database systems is too difficult for general users. To solve this, this paper proposes an associating, retrieval and display system for archeological information using huge 3D models of cultural heritage as interfaces to access information. To define target regions on 3D models, users can quickly select specific regions from huge models by using an interface that combines a splitting method by graph-cut and a lasso tool. In the display process, we achieved highly interactive rendering of huge 3D models by using an efficient 3D rendering algorithm on the basis of multi-resolution meshes.
