The Research Of City Environment Simulation System Based On Creator/Vega

Nowdays, Virtual Reality technique has been a research and development hot spot in the field of the computer science and technology .The Virtual Reality City has been an important applied aspect in the Virtual Reality technique. The research in the Virtual Reality technique not only has advantages of the development and application of Virtual Reality, but also has the great impellent effects in cartology, geography information system, digital city .In this paper, through the recognition of the virtual Reality technique and the development of Simulation City, research the technique and the method in building the City Environment Simulation System, some computational algorithms in building geometric model and in real-timing display optimization are proposed.The main work of the paper are:1, The analyzation of the actuality and development trend of the Virtual Reality technique.2, The analyzation of the development actuality of the City Simulation ,comparing with the development tools in City Environment Simulation system, this system chooses Vega as the auxiliary developing environment.3, Proposeding the principal data structure of the City Sence DataBase.4, The analyzation of the key technique in City EnvironmentSimulation System accomplishing. 5, Accomplishing the design of the System' s wander engine.
