| Urban Environment Simulation is the important achievement that the virtual reality technology is applied to the urban vision simulation. Virtual world own complexity and request for calculation real-time have extremely high expectations for equipment and the development of the software system lacks certain standard, which is not close enough with the combination of different trades. Therefore it has some characteristic, such as the great investment, the high degree of difficulty to studying and the research range widely etc. Now some domestic universities and colleges and R&D institution, have launched the research of urban environment simulation successively, and have made certain achievement. A lot of urban environment simulation system, based on special-purpose computer network, has been set up which support the distributed fictitious environment. In Ningbo, the digital urban Simulation centre becomes the first specialized digital urban Simulation centre in urban planning field of China and even Asia.Many solutions developed by business enterprises often support specific applications, which are not very competent for urban simulation environment applications.Under existing software and hardware terms, the following questions exist mainly in the construction of the urban simulation environment:In the respect of the model, because the domestic Urban Simulation project is just started, the specialized guidance and actual experience in making and management is lack, experience which can be referred have not ripe enough in managing and making procedure.In the respect of the establishment of reality, because of the limitations of high cost of manufacture and cycle , make them unable to have relatively better picture quality.In the respect of interaction, there is relevant less research now. In roaming actually, it is not comfortable for user to use. Though existing solutions are offering more interaction ways, but they have not considered people's interaction impression to the virtual scene.Taking consideration of the characteristics of urban simulation environment and the summary about the managerial procedure of simulation environment, a framework for urban simulation environment applications is proposed with the combination of modeling, which can effectively make up the shortcomings of conventional solutions. And from people's cognitive angle, the author makes an introduction in the interaction ways of people and environment. Finally, the author makes a preliminary research of how to make a realist environment through the way of the interaction ways and people's cognitive angle. |
