摘要 对三维城市的建模方法进行了讨论,提出了一种网格环境下基于SOAP(Simple Object Access Protocol)消息包的三维空间数据表达方法,并通过动态网格服务的方式为客户端的三维可视化提供数据源,通过解析SOAP消息包便可得到三维可视化所需的矢量数据、属性数据以及纹理数据等,再通过Java和Java3D技术实现城市模型的三维显示和客户端的交互操作。最后,在Globus网格环境下给出了基于网格服务的三维城市模型可视化的实验例子。 This paper discusses the method of 3D city modeling, puts forward an expression method of 3D spatial data, it bases on simple object access protocol (SOAP) message. The client side can acquire 3D spatial data through dynamic grid service. By parsing the SOAP message, user can acquire the 2D data, attribute data, texture data. Using these data, user can implement the visualization of city model and interoperability on client side by Java and Java3D. Last, the paper presents the experiment of 3D city visualization under the Globus grid environment.
