A Framework for Multi-Dimensional WebGIS Based Interactive Online Virtual Community
Multi-Dimensional (MD) web geographic information system (WebGIS) based 3D interactive online virtual community is a virtual real-time 3D communication systems and web systems development platform, fitted in running on a variety of browsers, achieved based on WebGIS technology and web VR technology. Four key issues are studied: (1) Multi-source MD geographical data fusion of the WebGIS, (2) scene combination with 3D avatar, (3) massive data network dispatch, (4) multi-user avatar real-time interactive. System is divided into three modules: data preprocessing, background management and front interaction. Core of the front interaction module is packaged in the MD map expression engine 3G WebMapper and the free plug-in network 3D rendering engine WebFlashVR. The test takes three campus of Ocean University of China (OUC) as an example. The result proves that our system is of high efficiency, usage and robustness.
