| 摘 要： | 针对虚拟城市仿真系统应用中OpenFlight模型缺乏、建模方式单一,难以构建复杂模型的情况,本文提出基于CAD文件来构建Opeflght模型的方法,在详细分析OpenFlight和DXF的数据组织结构的基础上,设计了基于DXF的OpenFlight数据创建方案并编程实现。通过实例测试证明该方案能快速、完整地进行数据转换,为虚拟城市系统的三维仿真模型构建提供了一条行之有效的途径。 |

| Abstract: | There are several problems such as lack of the OpenFlight models,singleness and difficulty of the modeling way in present urban application of the virtual simulation system.A new method for creating the OpenFlight model based on the DXF format is put forward in this paper,and after detailed analysis on the organization of above two data formats,the program has been developed to achieve the above function.It has been proved by experiments that the test data can be converted quickly and completely by this method,and this scheme will be applied into the creation of the 3-dimension simulation model in virtual urban system. |
