Abstract
The Web3D system has been widely used in the internet. It can show the 3D objects easily and friendly. On our "Web3D collaboration system", the Web3D is used as the interface of the visualization tool. The 3D objects have been transferred from the server using HTTP with the "Viewpoint", one of the commercialized Web3D. The multi-client system enables the visualization of the real-time simulation results with remote site. All clients can see the same results, simultaneously. This means that we can hold the remote collaboration with the real-time simulation. Also, the system has the feedback system, which controls the simulation parameter remotely. The transferred simulation data are displayed on the web, in real-time. In this paper, we install "Flash", very popular rich media software, on our system to improve its generallity.
