摘要:

In order to propagandize the fruits of the plan in the rural communities vividly and provide visual tools for the management of the layout information in the rural communities, this paper puts forward a new method to realize the interactive Virtual Wandering System in the Rural Community based on VRML (Virtual Reality Modeling Language). In this method, the establishment of the virtual scenes of the rural community includes two processes: One is the process of modeling the layout of the rural community, the other is the process of representing the texture data and leveled DEM (Digital Elevation Model) data based on VRML. The interactive operations of the virtual scenes, such as positioning in the scenes and spatial distance analysis, were also implemented based on the two processes. The first process is to set up the entities (for instance buildings, trees) in the community as the anchors with coordinates and attributes in the scenes. The other is to operate the anchors by Java and VRML. The method was applied to the virtual wandering system of Bashimudi village in Fangshan District of Beijing. The practical effect demonstrates that the system can glibly run at the network with the bandwidth of 100 kB and can respond to all kinds of requests from users in time. The system is suitable for the villages around the metropolis.
