摘要
探讨了基于FLASH的湛江虚拟旅游网上导航与全景漫游系统的构建以及各项关键技术,设计并实现了基于PV3D的全景浏览器,提出了基于Flash的旅游交通导航机制,对经典的A*算法作了改进,能够在网页上快速地计算出任意两个景点之间的最短路径,从而为自架车游客提供了最短路径导航服务;开发了管理维护性后台,对全景漫游、自驾车导航和公交车导航模块提供有效的增加、修改,删除信息。实际应用表明,该系统具有很好的跨平台、免插件、高效、扩展性和维护性。
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.
