摘要
虚拟现实技术在许多领域有着广泛的应用,但是由于传统的二维GIS的数据模型的限制,对于城市三维景观实时漫游,它的应用开发还比较困难。本文探讨了三维城市景观实时漫游的设计方案,给出了模型的建立、显示优化及数据调度的方法。
Virtual Reality VR technology has been widely used in recent years but it is difficult to develop a real-time walkthrough in3D Dimension city-sight because of being limited by the spatial data model of traditional2DGIS.This paper discusses a method about a real-time walkthrough in3D city-sight.The methods of constraction optimized display and usage is also given.
