基于改进场景图的空天信息场景管理研究

Research on Scene Management in the Aerospace Information

由于三维空天信息系统场景复杂,动态场景多等特点,通过研究场景图和空间划分结构技术,本文提出了一种改进场景图的空间划分结构模式,在此场景组织方式下,采用lazy算法进行动态场景管理,加快基于raytracing渲染算法的动态场景绘制速度。实验证明,采用这种场景管理方式,对于空天信息场景中的静态物体和动态物体能够进行很好的管理,满足了系统实时绘制需要。

A novel organizational structure design was proposed,aiming at organizing the simulation entities in aerospace information system,which the dynamic scene more,scene complicated.the design which is easily extensible with various spatial data structures in the scene graph.at the same time,using lazy evaluation techniques to manage the dynamic objects.The result proves that using this scene management method,for the static and dynamic scene objects can be well realize,and demonstrate that they achieve real-time rendering performance.
