基于J2EE和JOGL的道路网络三维可视化研究
|
摘要
针对道路网络三维可视化中的难点问题,提出了一种实现方法:利用J2EE平台作为整体框架,基于边折叠算法和分段策略分别建立数字地面网络模型和道路网络模型,并运用数据压缩、多线程、客户端缓冲区等策略对模型数据的存储、传输、缓冲等过程进行了优化。运用该方法实现了道路网络三维可视化,并将其成功运用于高速公路的设计及方案发布过程和高速公路远程建设可视化管理中,结果表明:采用J2EE,JOGL和上述优化策略能够很好地解决道路网络三维可视化中的数据调度、数据压缩、客户端实时渲染等问题;该方法对数字公路的建设和推广有重要价值。
A method of realizing the road web 3D visualization was proposed against difficult problems of Web 3D.Java 2 Enterprise Edition was applied as the overall framework.Digital terrain web model and road web model were built based on edge collapsed algorithm and subsection pdicy respectively.Several other means such as data compression,multi-threading,client cache,etc were utilized to optimize the storage,transmission,cache processes of model data.The author developed a road design proposal web 3D release system based on the way above-metioned and used it in the design and proposal release process of highway successfully.The result of this utilization indicated that problems such as data dispatch,data zip,model rendering on the client can be solved because of the adoption of J2EE and JOGL and optimization tactics metioned.The method is valuable for the construction and popularization of digitalization road.
