基于Skyline的海量3维实体模型管理与显示

Management and Display of Massive 3D Entity Model Based on Skyline

简要介绍了当前的几种3维建模方法,重点针对海量3维实体模型的管理与显示问题,基于Skyline 3维软件平台,紧密结合2维GIS中成熟的空间数据管理能力和强大的空间分析功能提出有效的解决方法。最终在上海市警用3维地理信息系统中进行展现,流畅快速地加载数以万计的海量3维实体模型,并提供新颖的琴键式展示效果。同时研究成果展示了3维GIS与2维GIS集成的可行性和优势,可应用到其他3维系统中,实现框选或圈选进行各种属性查询及其他分析功能。

Briefly summarized couples of three-dimensional modeling method,the paper,based upon skyline three-dimensional software platform,put forward effective solutions which focused on management and display issues of massive three-dimensional entity model,which closely combined sophisticated spatial data management capabilities and powerful spatial analysis function of two-dimensional geography information system.Finally,it implemented in Shanghai police three-dimensional geography information system,the method loads thousands of massive three-dimensional solid model smoothly and quickly.Research results show practicability and advantage of the integration of 2D GIS and 3D GIS which can be applied into other three-dimensional systems to inquiry various properties by box or circle check and achieve other analytical functions.
