Design And Application Of Virtual Digital Campus

With the further development of digital technology and educational cause, virtual reality technology has become one of the hot issues in current research work, at the same time, the application of virtual reality technology at college are more and more widespread. The real campus image is reproduced stereoscopically in the internet via virtual reality technology, and it aims to achieve optimal management of the campus so that more people can know about the school, which has become a necessary mean for colleges and universities to improve themselves images and reputations. Virtual campus building will help to improve the reputation and optimize the management of the school, meanwhile, it is very important significant to construct the campus Digitalization, advertise themselves,as well as Recruit students.This essay primarily studies the virtual digital campus as the background in the large and medium-sized scene virtual process in the presence of elements in the scene image texture aliasing, compared to the real world, The collision detection of the objects in virtual scene is not Intelligent enough, and the rendering of the Viaual scene is less real.Study contents are summarized in three parts:firstly, the study of creating a Viaual scene modeling technology of three dimensional model, comparing various modeling methods and summarizing for the system-created method of hybrid modeling so that achive to modeling the three dimensional scene of virtual scene texture mapping, which is based on VC++and OSG; Secondly, for the promble of element images texture aliasing in the Viaual scene, this article studies and imporves the algorithm of texture mapping with fast anti-aliasing, Put forward the Improved Algorithm of Virtual Scene Fast Anti-Aliasing Texture Mip-Mapping, named IA-VSFATM,which the model in Three dimensional Viaual scene can be optimized. Finally, for these issues that compared to the real world, the collision detection of the objects in the Viaual scene is not Intelligent enough, and also the rendering of the Viaual scene is less real, this essay studies on the implementation methods of interaction walkthrough of virtual campus scene, specific effect and collision reaction functions, which based on AABB collision detection technology, modify the OAABB collision detection algorithm through multiple computing detection, not only the operating efficiency of the collision detection is guaranteed, but also the intellectualized judge accuracy of the collision detection is improved, in oreder to realize the collision intelligence reaction.To realize the essay designs and fulfills an implementation of a complete set of virtual campus roaming system, as well as the method of interactive fuction, there are the academic characteristics as below:(1) enhancing the element images texture aliasing in the Viaual Reality scene, so rendering of the Viaual Reality scene is more vivid; (2) improving the intellectualized judge accuracy during the virtual objects in the collision detection, for making the dummy activity closer to the real world.finally released to the Internet in the form of the file, so that more users who have no chance to go to school can be personally on the campus scene through INTERNET browsing to know more about the school.
