Abstract:

In order to establish a simulation system of the urban water supply network based on virtual reality, the running conditions of the network are simulated in a 3 D scene. In the simulation, first, an engineering database of the water supply network is built to ensure the accuracy of the 3D simulation model. Next, a 3D model of the urban water supply network is established based on the 3 D models of the valves and pipes constructed via MultiGen Crea- tor, and is then driven by Vega to implement the scene simulation of the running conditions using VC ＋ ＋ MFC and EPANET software package. The results indicate that the established simulation system based on the virtual reality directly displays the information of the urban water supply system, and that it well simulates the topology linkage as well as the running conditions, overcomes the limitation of the traditional geographic information system and is of higher precision and greater reliability.

Key words: urban water supply system, water supply network, scene simulation, virtual reality
