| Abstract: | 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. |
