【摘要】 三维地形虚拟现实技术是当前计算机图形学、地理信息系统和数字摄影测量技术研究的热点问题。本文研究了以Client/Server结构模式为基础进行的三维地形虚拟现实系统的设计与实现。从数据服务器对地形三维数据的组织和管理方式、客户端三维地形可视化的应用程序以及客户端与服务器的连接及数据传递技术三个方面进行了研究,并进行了系统的测试。试验结果表明,本文的设计方案是可行的,可为地形三维可视化的进一步发展提供一种思路。更多还原

【Abstract】 The study on 3 D Terrain VR is a hot topic in Computer Graphic,Geographic Information System and Digital Photogrammetry. The design and implementation of 3 D Terrain VR System is discussed based on Client/Server architecture. The article primarily discussed three problems about 3 D Terrain Data being organized and managed in the database server,3 D Visualized Terrain application in the client,the connection and data transfer between client and server. After 3 D terrain VR System tested,trial result showed that the design project is available, can provide a kind of way for the further development of 3 D visualized terrain.更多还原
