Collaborative virtual traditional Japanese crafting system over the Japan gigabit network II

Virtual Reality technology performs very important role to design and construct desired buildings houses In this paper we introduce an extended virtual Japanese traditional crafting system to collaborate by many users such as end consumers, craftsmen coordinator and salesperson each other The high immersive system in consideration of the collaboration support over the next-generation network (JGNII) is proposed We av building the presentation system which takes sensitivity into consideration to virtual reality environment It has so fa mounted by proposing three systems of an Internet version (Java+ VRML and Java+Java3D) and a CAVE version We think that collaboration support in share space is required of remote users Multiple CAVE systems in diferent locations a,v interconnected to organize a collaborative virtual reality environment over Japan Gigabit Network (JGN II) which is a testbed network in Japan with several ten Gigabit/sec A larger number of traditional Japanese fittings in several local cities am redesigned by 3DCG computes into CAD data and stored in 3D database systems over JGN II Users can share the virtual space, interactively collaborate, retrieve form the distributed DBs to realize the desired interior space in the house for consumers We implemented a 3D presentation system by OpenGL and IRIS Performer in CAVE environment on JGN 11 and built a prototype system. As a result, we could verify the usefulness of the suggested system sure it provided not only higher potential on deign capability and productive efficiency bid also made user satisfaction much better on build a new house.
