A FRAMEWORK FOR GENERALIZATION OF 3D CITY MODELS BASED ON CITYGML AND X3D
CityGML X3D Generalization CityTree Visualization Aggregation City model Multiple representation data structure
2014/10/16
In this paper, a novel framework for generalization of 3D city models based on CityGML and X3D is proposed. In the proposed framework, the CityGML files are first parsed into a Java environment to acq...
基于X3D和GPS的立交区域车辆监控框架
X3D技术 车辆监控 框架
2009/7/31
针对立交区域的监控系统难以准确实时地对车辆进行监控的问题，该文以X3D和XML为基础，提出在真三维环境中进行车辆监控的技术框架。框架集成三维建模技术、X3D技术、差分GPS技术、数据库技术和车辆运动模型，对行驶在立交区域的车辆进行实时监控，准确定位当前车辆的具体路段。实验证明框架是可行的，可用于车辆监控及交通仿真和车辆行为的分析模拟。
基于X3D的交互式变电站信息可视化管理系统
虚拟制造 X3D 信息可视化 可视化管理
2009/4/17
针对三维信息系统并未在虚拟制造上得到广泛应用的现状，通过结合Extensible-3D(X3D)和Java程序语言，构建出一个具有人机交互效果的3D变电站信息可视化管理系统。系统的特点是可以在三维场景上直接进行信息管理操作，同时系统会将修改信息自动存入数据库中，再次运行系统时会自动重建三维场景。应用实例表明，所提出的系统架构具有交互性、可视化的管理特性，改变了过去单纯通过文字或二维文件进行信息管理...
