Design And Application On The Community3D Landscape Interaction Roaming System

Virtual reality technology is used to create a virtual scene of real world in the computer world and let people feel real images of real scenes through virtual screen, which mainly use artificial means, computer modeling and processing technology. Virtual reality technology has characteristics of dynamic interaction as roaming technology, which can make the person experience the scene more realistic feeling personally, also plays a decisive role in the digital construction of modern landscape architecture.Firstly, in view of the problem of low customer participation and satisfaction traditional virtual roaming system, this paper puts forward a landscape roaming system design based on virtual technology, designs the overall function structure of a kind of interactive3D Landscape roaming system. In addition, the system construction and implementation process are analyzed, optimized and designed in detail. Secondly, In order to reduce the system’s complexity of the3D model, an optimization algorithm based on spherical sky box modeling is presented in this paper, the optimization algorithm reduce the complexity of natural landscape terminal scene model and enhance the operating efficiency of the system interactive function. Thirdly, in order to tackle with the drawback of the static browsing functions cannot meet customer’s personalized interaction demand in traditional virtual roaming system, this paper introduces the virtual character model into system design, and the automatic roaming and interaction path control model are utilized for the user choice. Through the path selection algorithm, the user can manipulate virtual character model through the keyboard and mouse and other tools to communicate and interact with the virtual scene system well. Finally, we use special test software to test and analysis the running, debugging and performance of the designed system.The research of this subject has obviously practical value and will greatly promote the research and development of modern virtual scene interactive roaming system.
