信息时代悄然而至,人们已不再将可以定量表达的信息结果局限在2维空间上,逐步向3维空间信息表达深入。利用虚拟现实技术,建立3维信息模型,对存储在数据库中的信息数据进行提取、处理,实现了3维信息的虚拟可视化以及虚拟环境中数据交互查询和交互操作的全过程,并在3维虚拟环境中实现了相应的数据空间分析。 更多还原

【Abstract】 With the information age knocking softly,people do not limit qualitative information results in two-dimensional space any longer,whereas gradually deep into 3D spatial information expression.The 3D information model has been set up by the virtual reality technology to extract and process information data stored in the database,realizing the virtual visualization of 3D information,the whole process of data interactive query and operation,and the corresponding data space analysis in 3D virtual env...
