VRML-based Virtual Roaming System For Interactive Research Community

With the rapid development of information technology in today’s world, virtual reality technology is changing our lives. Virtual reality technology in the industrial, architectural design, education and training, culture and entertainment so widely used. Virtual reality technology and computer network technology has become a computer software research and application of hot spots. Virtual communities are in Digital City is a very important application of virtual technology, community environment virtualization and digitization, but also convenient for community workers to community environmental planning and management, but also allow visitors through a network of community A quick browse, to save time.Virtual reality interactive virtual environment enables more realistic, gives rise to the immersive feel. Collision detection is a three-dimensional virtual environment the user to interact with the virtual world an important means of both accuracy and authenticity of the system need to be controlled by the collision detection algorithm. The contemporary virtual reality system still exist collision detection accuracy is not high, slow response and other shortcomings, this article in the realization of the basic system on a virtual community of collision detection algorithms are analyzed and presented an improved collision detection algorithm.The main work of this paper are:(1) through access to information and knowledge to learn the theory and technology of virtual reality technology, the use of3D MAX tools to build a virtual community, and use VRML to optimized the model of virtual community.(2) a theoretical analysis of collision detection algorithm and the algorithm was improved.(3) describes the virtual reality interactive technology and the use of interactive technology in the process of implementing a virtual community system, and compare the advantages and disadvantages of various interactive virtual reality technology, and the use of human-computer interaction mechanism of three-dimensional scene entities basic manipulation. The use of interactive technology to enhance the virtual community roaming system.
