| Abstract: | Some key techniques on constructing a panorama roaming and navigating system of Zhanjiang virtual tourism environment on Web with Flash platform and technologies were explored. Firstly,a panorama viewer was designed and implemented based on PaperVision3D. Secondly,a tourism navigation system was devised by simplifying A* algorithm to implement it with ActionScript and Flex programming for the purpose of computing the nearest distance between two locations. Finally,a maintenance management subsystem was developed to allow users to insert,delete and update panoramic images,texts,routs and so on at rear-end. Numerous practical applications show that this system possesses cross-platform,free Plug-in installation,Web high-efficiency and easy maintainability. |
