虚拟现实技术在都江堰三维信息系统中的应用

Application of virtual reality to Dujiangyan 3D information system

以四川都江堰虚拟现实系统的构建为例,介绍了虚拟现实技术应用于流域模拟的一些关键环节,重点探索了多比尺地形嵌套建模、水流模拟、场景漫游控制、多专题切换、工程设计仿真以及与外部数据库连接查询等问题的解决方法,为虚拟现实技术更进一步应用于流域模拟进行了有益的尝试。

As a new kind of technology, the virtual reality is more and more recognized by geographical industries in recent years. In this paper, several key points on the application of virtual reality to valley simulation are discussed based on the construction of Dujiangyan virtual-reality system, including multilevel terrain construction, fluid simulation, scene roaming controlling, multi-subject switching, project simulation and database connection, the research of all these aspects would be significant to the virtual reality application to valley simulation.
