基于VRGIS平台的数字世园系统的设计与实现

世界园艺博览会是在我国举办的又一次国际性盛会,数字世园系统的建设成为世园会对外宣传、招展和管理的重要平台,针对世园会高精度、高密度、海量数据的特点,以VRGIS平台为基础,设计并实现了数字世园系统,结合三维建模、空间网格索引、LOD等数据管理和自适应调度技术对世园会进行三维仿真,保证了海量三维世园场景高效管理和交互流畅,在此基础上开发辅助世园会规划设计、宣传招展、设施管理等功能,为世园会管理提供了三维可视化管理平台。

Research and realization of digital expo system based on VRGIS platform

The world horticultural exposition is another international event held in Cl：＇~na. The realization of the digital world garden expo system serves as an important platform for foreign propaganda, dressing and management. According to the characteristics of the expo data which is high precision, high density and massive, and based on the VRGIS platform, this paper describes the realization of the digital world park system and simulations on the international horticultural expo combined with data management and operation techniques such as three-dimensional modeling, space grid index, LOD, which guarantees that the interaction of the massive three dimensional world garden scene is fluent. Based on the digital expo system, we have developed several functions such as auxiliary planning design, publicity expo and facilities managements. It offers a three-dimensional visualization platform for the international horticultural expo management.
