Basic consideration of 3D digital traditional Japanese crafting system

In contrast to the modernization of the industrial structure the traditional Japanese crafting industries have not always introduced advanced technology. So, in order to activate those industries as local industries, it is required to promote their activities, train up their successors and improve their productivity. We propose a user-friendly three-dimensional CG presentation system for typical Japanese crafting industries. Using our proposed system, a user can retrieve fittings from a distributed database based on the user´s perception, see fittings without spoiling the natural beauty and design and present a interior/exterior rooms using a high speed network. In order to realize the presentation space from many three-dimensional fitting data stored in a distributed database system on the Internet, we classified the presentation space model and implement our system using VRML and Java
