Research On Awareness Model And Its Key Techniques In Multi-user Virtual Environment

Multi-user Virtual Environment(MVE) with the development of virtual reality technology and network technology has been applied in many other fields. The paper analyzed the key features of the existent MVE and the characteristics of it's awareness mechanism, summarized the main issues facing MVE, and pointed out the important position of awareness management techniques in MVE.In connection with the current development needs of MVE, the paper analyzed the characteristics and limitations of the past awareness scheme and designed a kind of awareness management scheme which adapt to the new development needs. The scheme combined the features of space interactive awareness and user dynamic interactive awareness. So the scheme can better meet the development trend of MVE. Then, the paper researched several of key techniques involved in the process of awareness management realization in MVE. The paper focused on the work of the research and realization of avatar, BSP-Tree scene segmentation algorithm and LOD model.Finally, the paper was summarized and pointed out some problems to be resolved.
