Development Research On Urban Landscape Simulation System Based On Virtual Reality Technology

The virtual reality technology is one kind of computer application technology which applies widely. Urban landscape simulation based on virtual reality technology is important domain of visible research ,It have displayed the good application prospect in the planning and construction of city.The urban landscape simulation system's development needs to collect massive correlation data. So the author took the data management the initial station, introduced the urban landscape simulation foundation database, then according to the system composition structure division,some technical questions of the scene modelling and roams engine realization were elaborated, finally the author explored the project management of system performance with the practical work.The paper's significance : The research has proven the essential technology of scene modelling through the experiment, summarized the method which used for constructing model and synthesizing model, meanwhile the management of system development was explored .This thesis consists of six chapters:Chapter one is an introduction. It reviewed the present situation of research, introduced the topic origin, research method, technical route and research significance. In the second chapter, the urban landscape simulation foundation database was introduced. The author divided the data which the system needed into two categories and realized the data management with the database.In the third chaptert, the essential technology about geometry modelling of hypothesized scene was summarized. Processes for manufacturing three types models was expounded in detail. The author introduced two ways of scene synthesis and maded the comparative analysis later. In the fourth chapter, general 3D roaming engine that suits the wide range landscape simulation was designed and realized.In the fifth chapter, basing on the practical work, the author discussed the project management of system development and made a comprehensive introduction to the process of system development.In the sixth chapter, the kernel and innvation of the thesis were summarized.
