摘要
结合基于Vega Prime的"数字港口"三维可视化系统,分析了系统构架设计和场景数据库优化管理,针对三维重建可视化效果和运行效率之间的矛盾,提出了系统运用的图形数据动态调度、动态LOD(Levels of Detail)、实时软阴影优化等关键技术,并通过试验证明了该方法能够在系统流畅性和高仿真性之间获取较好平衡。
After analyzing 3D visualization system for the digital port based on Vega Prime, we propose the architecture design of system and scene graphics database optimization and management. Concerning the confliction between getting better visualization of 3D reconstruction and system efficiency, we present some key methods, including dynamic data schedule, dynamic LOD （Levels of Detail）, as well as optimization for real-time soft shadows. A decent balance between the system fluency and high simulation can be achieved by these techniques, as shown by experimental results.
