摘要
X3D是新一代的互联网3D图形规范,为构建基于Web的虚拟三维场景及其人机交互提供了一种新的途径。提出了基于X3D的虚拟三维场景的建模方案,采用了地理信息系统的图层化方法将虚拟三维场景数据划分为独立地物、植被、交通、建筑物和数字地形等数据层,介绍了各数据层的三维建模及实现方法,并以一个典型的城市小区为例阐述了虚拟三维场景的优化与整合技术。
X3D is the next generation of lnternet 3 D graphics standard. It provides a new way to build a Web- based virtual 3D scene and human-computer interaction. The modeling solution of virtual 3D scene based on X3D was proposed. Using layers method of geographic information system, a virtual 3D scene was divided into a series of data layers including individual feature, vegetation, transportation, building, and digital terrain. And then 3D modeling and implementing methods of every layer is presented. Finally, optimization and technologies for virtual 3D scenes was stated for a case study of a City district.
