基于地理信息三维场景动态展示研究

Research on three-dimension scene dynamic display based on geographic information

用非传统的三维建模方法——规则建模方法,结合二维地理信息属性数据进行三维建模,创建出接近现实的石油储库场景模型,同时,在基于工作流的图形界面里展示节省CPU的内存,减少软件运行时的数据流量,提供出画面流畅的大型石油储库三维场景效果,并解决了场景的扩建与重建问题。

The paper adopts the irregular three-dimension modeling method and regulation modeling method, undertakes the three-dimensional modeling by combining with the two-dimension geographic information attribute data, creates the oil storage scheme model close to the fact, displays the saved internal memory of CPU based on the graphic interface of the workflow, reduces the data volume of the operation for software, and provides the large three-dimension scheme effect with smooth pictures, so it solves the extension and reconstruction of the scene.
