摘　　要：针对较大型桌面虚拟漫游系统在目前计算机水平和网络环境下较难实现虚拟环境的真实感、沉浸感、网络传输流畅性及运行平稳等问题;研究了三维建模、贴图处理等基本数据采集方法、利用LOD细化层次技术提高场景的绘制速度、Java和VRML交互技术增强用户与虚拟场景的交互性,并进行了相关优化处理以减少文件量。结果表明,开发的内蒙古工业大学部分校园桌面虚拟漫游系统,可实现视点切换和随机无阻碍漫游,具有较强的沉浸感和真实感。Presently,the level of computer techniques and network environment can hardly offer a sense of realism and immersion for the viewers in virtual environment and can hardly solve the problems of smooth transmission and stable running of the network.Some research work has been done,which includes the basic data collection for three-dimensional modeling and texture processing,the upgrading of LOD（level of detail） technology for improving the rendering speed,the use of Java and VRML interactive technology to enhance the user′s interaction with the virtual scene and the optimization treatment for reducing the volume of documentation.Final results indicate that the Virtual campus roam system developed on the campus of Inner Mongolia University of Technology can achieve viewpoint switching and random roam,as if the viewer is involved in real scenes,experiencing a feeling of immersion and realness.
