摘要
虚拟校园是可视化技术需求最为迫切的领域之一,虚拟现实技术可以广泛应用在虚拟校园的各个方面,并带来切实的效益.以第2炮兵士官学校虚拟校园的建设为例,对虚拟校园实时漫游系统的建模技术、实时显示技术、渲染技术的优化方法进行了分析,给出了模型优化、场景调度、渲染加速、实时驱动的计算方法,并对可见性判定和消隐技术、细节层次模型、纹理映射技术等进行了初步研究.
Virtual campus is one of the research fields that are mostly urgently needed in the visualization technology. The technology of virtual reality can be widely used in all aspects of virtual campus and it can bring along much benefit. In this paper, taking the Second Artillery Sergeant School as an example, the authors analyzed the technologies of modeling, real-time displaying and rendering of the virtual campus＇ s real-time roam system, gave calculation methods for model optimizing, scene updating, render accelerating, and real time driving, and made a preliminary research on the technologies of visibility judgment, removing and hiding, detail hierarchical model and texture mapping.
