Design And Development Of Flash 3D Virtual Science Museum

Flash3D technology based on multimedia technology, combined the technology of panorama, stereo display technology, the script editor and interactive technology and other high and new technology, building a realistic virtual environment?Users with the aid of the mouse, keyboard and other computer external terminal equipment, personally experience interactive roaming virtual functions of virtual environment and the dynamic interaction function of the object in virtual environment. Based on the implementation of the above functions, giving users an immersive sense of reality?In recent years, with the rapid development of Flash3 D technology, its application field is more and more wide. Among them, the Flash3 D technology in the application of the virtual display system gradually has become a hot research field. As an important part of virtual display system, virtual science museum,s location is indispensable. Nowadays, some universities have begun to research the design and implementation of virtual science museum. In order to facilitate the rapid spread of popular science knowledge of the public, as the virtualization environment of the science museum, science museum create an immersive sense of reality. Through the interactive roaming in the virtual science museum, the public can break the limitation external conditions.Based on Shandong province science and technology museum, this study builds a system of virtual vagile science and technology museum on the Away3 D platform configured with Adobe Flash Professional CS6 software environment. Virtual science museum implement the interactive display of each exhibition hall and the exhibits of science and technology museum system. Users understand detailed information of exhibits and arrangement and layout of exhibits by the operation of the external device. The content of this research mainly includes the following several aspects:1. This research expounds research significance of the virtual science museum and introduces the research status of Flash3 D technology and science museums at home and abroad and the knowledge of Flash3 D technology and virtual science museum. This research expounds the development platform and the key technology used by virtual science museum.2. Based on detailed exposition of the development of virtual museum system environment and principle of virtual science museum system, the study analyses requirements and education function of the system. On this basis, the paper expounds development plan of the virtual science museum system.3. The truth extent of virtual science museum depends on selections of models in virtual science museum and the quality of the image synthesis. This study used different methods of Shooting of scenes and exhibits. In the display part of the scenes, in order to ensure Altitude simulation of the virtual science museum, the paper based on the method of scene construction, choose the appropriate image synthesis method and projection model. In the exhibition part of the exhibits, In order to ensure consistency of location and tonality of the exhibits from different angles, the paper should pay attention to the aspects of the lighting, the background and the center of location, etc.4. The sense of immersion of virtual science museum depends on the interactivity of virtual science museum. To strengthen the sense of reality of virtual science museum and the participation of system users, this study based on Away3 D platform focuses on the settings of interaction, including the mouse interaction, keyboard interaction, the creating of a camera controller, etc. At the same time, the paper expounds the running effect of the virtual museum system and the aspects needing to test in the process of running.This study introduces the overall structure of the virtual science museum and the technical realization methods, providing a development plan which can satisfy the basic requirement of science and technology museum of educational virtual museum system. The paper deeply Research and explore several techniques of constructing virtual museum system, completing functions which a virtual museum scene should have such as automatic navigation, autonomous browsing and functions that presenting detailed information of the exhibits. Users can independently roaming in the virtual science museum, and can experience a series of realistic interactive operations.
