| 摘 要： | 传统的三维地形可视化技术存在过多的节点分解合并,影响实时渲染帧速。为此,研究基于ArcGIS与3ds MAX的三维地形可视化技术。将采集的地形数据导入至3ds MAX软件中,构建三维地形模型,采用Geodatabase数据库有效的保存和管理其相关数据,利用ArcGIS中的ArcEngine组件实现三维地形可视化。测试结果表明:在地形区域大小和视场角相同的情况下,与传统的可视化技术相比,使用基于ArcGIS和3ds MAX的三维地形可视化技术,避免了大量无谓的节点分解合并,实时渲染的帧速明显提高,证明该技术能有效提高实时渲染的效率。

| Abstract: | Traditional 3d terrain visualization technology has too many node decomposition and merging,which affects the real-time rendering frame rate.Therefore,3d terrain visualization technology based on ArcGIS and 3ds MAX is studied.The collected terrain data was imported into 3ds MAX software to build a 3d terrain model,and Geodatabase was used to effectively save and manage its relevant data.ArcEngine component in ArcGIS was used to realize 3d terrain visualization.Test results show that the same size and in the region of the terrain and the viewing Angle,compared with the traditional visualization techniques,using ArcGIS and 3ds MAX based 3d terrain visualization technology,avoid a lot of unnecessary merge node decomposition,real-time rendering frame rate significantly increased,proved that the technology can effectively improve the efficiency of real-time rendering. |
