Research On The Dynamic Interactive Technology For Virtual Scenes Based On G/S Model

With the rapid development of network technology and virtual reality software technologies become more sophisticated, it has been not satisfied with two-dimensional space interactively, and hope that experience an interactive three-dimensional space. Interactivity is a kind of experience can provide a more natural way, including telepresence, interactive, dynamic effects, continuity, and user participation in the exploration of language. Dynamic interactive technology combined with its 3D modeling technology to build the virtual system, the realization of its interactive features, can be truly object-oriented, cross-platform, distributed Web browsing. Dynamic interactive virtual reality scenes is an important feature of virtual reality technology is applied to one of the main advantages of the virtual scene. Design and Implementation of Interaction in the virtual environment plays a decisive role, will have a direct bearing on the success of the virtual system. Geo-Information Browser (Geo-Information Browser) and Distributed Spatial Data Servers (Distributed Spatial Data Servers) in the G / S mode appeared and show its unique charm, provides us with an interactive three-dimensional space, bringing virtual reality one world concept. This paper explores the new, advanced G / S mode, in this mode to better use the dynamic interaction techniques, change the traditional product model and other issues.In this paper, include:1,Implemented based on plug-in Geo-information Browser design Analysis of Digital Earth Platform, the background, structure and technology system of the G / S mode, On the popular G / S model to analyze the application and development trend of discussion;Using Google Earth API and the JavaScript by linking the browser embedded in Web, the pair of G / S mode of G-terminal form of extended, improved and enriched the G / S mode, and analysis of Geo-information Browser based on Earth plug-ins to show the advantages in the three-dimensional.2,Implemented the design of dynamic interactive platform for virtual scenes based on G/S model3D technology, a number of current research, comparing the characteristics of each technology and the advantages and disadvantages. Focuses on G / S mode, a number of dynamic interactive technology, and a specific method and existing strengths.Of the G / S mode, full use of Geo-information Browser's the following two advantages: the same spatial location and geographical coordinates, combined with vision and close-range scenes can be achieved contrast, in the virtual scene by adding dynamic interactive technology that allows users with more opportunities for exchange have a more realistic experience of community-based tours, so on the basis of the virtual roaming system goes a step further.To enhance the realism, the scene is movement of people and vehicles. System realizes the user interact with the scene, which enables participants to have a feel of the experience, through interactive way for users to experience immersion. Users can mouse, keyboard and other means to freely switch the viewpoint in the virtual scene and perspective to roam, click the button or menu, etc., for information access and operation of the scene, giving the user visual or hearing, resulting in the virtual world and interactive interactive experience. Users interact with the virtual environment is multifaceted, the user can choose both the tour route, from any angle, using a variety of exercise methods (such as walking, driving, etc.) to watch the virtual scene; also can change the scene according to their own wishes, multi- Kinds of subjectivecomparison.According to the proposed solution, and integration for "Qingbaijiang Logistics Park Information Construction Project ", the combination of digital travel, digital hotel, three-dimensional example of the logistics park system test data. Promote the use of the system will be in G / S model the way forward towards the development of meaningful step.Finally, the paper summarizes the research results, and the need to implement extensions, identify shortcomings and the next step.
