| 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. |
