Research And Implement Of Scene Visualization And Roaming

Virtual reality technology (Virtual Reality) has become a new integrated information technology in the end of the 20th century. And scene visualization simulation is a form of expression of virtual reality, It's real-time performance of the three-dimensional capabilities, the interactive nature of the human-computer operating environment and the immersive experience, which will fundamentally change the status that the boring, stiff and passive between men and the computer, people can see, hear, touch and the other human habits and natural way to feel and understand computer-generated virtual world, and promote exchange of people and the environment, more in-depth develop human wisdom. This is the charming of the real-time 3D technology roaming the campus. This kind of campus planning should be the future direction of development.The definition of Digital Campus is defined under the concept of Digital City which take an important part. Virtual campus is a space of specific applications in virtual reality which technology in the digital campus building. In recent years Digital Campus has become the most significant part of study, so the virtual campus has a very important theoretical and practical value to learn.Based on the analysis of the visual visualization technology development and application, focus on the visual simulation theory of knowledge and technology generated scenes,the model database optimization technology and interactive technologies such as collision detection technology, which based on the Creator/Vega Platform. And I design and implement the optional path on computer interactive robots. My research is achieving paths optional and roaming in the virtual reality technology area,and applies it in the visualization campus scene. And for the first time unifies the man-machine engineering theory and visualization campus's roaming, causes the visualization campus to have the theory and the practical significance.Among the main contents are as follows:First of all, practical significance should be taken into account in the three-dimensional visualization of visual roaming the campus in actual situation, make the design and proposed design options, and gives the design flow. Making use of existing Google Earth software to get the size of the campus accurate data, flexibility in the use of texture mapping technology, external use technology, billboard advertising technology, database optimization model of three-dimensional modeling technology, and other key technologies, to complete the construction of three-dimensional model, and then make the three-dimensional model simulations in Vega/Lynx interface, the final application is of VC/MFC framework, and do simulation programming, the to realize of the optional path of the roaming and roaming free. This subject to a car for the protagonist of observers to track cars and finally realize the visual observation and interaction.
