基于DXF文件快速构建OpenFlight模型
onstruct OpenFlight based on the DXF Rapidly
多源空间数据共享一直是VR应用系统开发中需要解决的重要问题。DXF作为CAD图形数据的标准交换格式，对于VR软件来说，实现DXF到OpenFlight（VR空间数据格式）的数据转换具有重要意义。本文在分析了OpenFlight和DXF的数据组织结构的基础上，设计了DXF到OpenFlight数据转换方案，并用程序实现。经测试，数据转换完整，结果可靠。
Sharing between various spatial data has always been a main problem to the development of VR application systems. DXF is a kind of the standard exchange format of CAD graphic data, so it is significative for VR software to realize the data conversion from DXF to OpenFlight, a spatial data standard format for VR. In the paper, the data model of OpenFlight and DXF spatial data were studied, a scheme of transformation from DXF to OpenFlight is put forward, and the algorithm is also implemented. Tests prove that the spatial data are transformed completely and the results are reliable.
