Design And Implementation Of Virtual Campus Roaming System Based On OSG

Since the late20th century, Virtual reality has been the field of information technology research, development and application of one of the hot direction. It is constructed using the computer a very realistic virtual reality environment, but the skills to support users to experience it naturally. Now has been widely used in military, scientific visualization, education and training, design, and planning, virtual testing, virtual tours, shopping, interactive entertainment, engineering technology, such as many areas of science and technology exploration.This paper introduces the concept of scene graph theory related, OpenSceneGraph architecture. Presents a custom particle systems, successfully simulated the effect of rain. In addition, according to the actual situation of GuangXi Normal University campus, intense competition, the integrated application of virtual reality technology, using3D modeling software-3DS MAX2009software, integrated development environment, Visual C++2005and the open source OpenSceneGraph3D rendering engine, designed and implemented the virtual campus roaming system of GXNU. This system could provide users with friendly, realistic virtual environment, giving the feeling.Finally, this article summarizes the work done, pointed out the areas to be improved, and the future study are pointed out.
