I Distributed Virtual Reality System is a graphic system that supports the multi-people real-time interactive through working. In a virtual environment, every user can interact with other users through puter on . The research work of DVR started in 80's 19th century, and rapid development working technology further boost the research and development of DVR. "Networking puter" has gone deep into everybody's mind. makes people on the earth contact one another. People stride over the geographic gulf and share resource, exchange information, or discuss specifically problem through working. This paper introduces a systemic research of a new DVR application development environment, and uses the technology to build a simple mono system of simulation of dam. We can build the client and server on different Operation System. Using the special client, user can access to the simulation server through working. The main works of this paper are as follows: 1. Building the 3D scene through the working-based interactive 3D modeling software standard —X3D. 2. Developing the browser which can explain, execute, presentation X3D files using in-line the open source provided by the pany and Web3D
