摘要
虚拟现实技术强大的三维显示和交互能力,为解决地学领域中地上地下统一建模、空间分析等科技难题提供了新的研究手段和方向。以虚拟现实系统为平台,结合三维地质建模技术构建了虚拟城市地质环境,实现了地上与地下的集成建模,并对虚拟环境中二维导航、空间查询等交互功能进行了研究,从而为城市规划、建设和管理提供三维可视化决策平台,为建设"城市地质信息管理与服务系统"打下良好的基础。
A new research method and direction for solving the technology problems in the field ofgeosciences, such as the united modeling of overground and underground entities and spatial analysis, is provided by the powerful three-dimension visualization and interactive capabilities of virtual reality technology. Virtual urban geological environment is constructed by virtual reality technology and three-dimension geological modeling technology, the integrated modeling ofoverground and underground entities is realized, and the interactive functions such as 2D-digital map navigation and spatial query in the virtual environment are researched, which provides the decisionmaking platform of three-dimension visualization for urban planning, urban construction and urban management, and is a good foundation for construction of ＂the management and service systems for urban geological information＂.
