A PC based Real-time Rendering System for Complex Scene

论文研究了基于微机平台的复杂场景实时生成的关键技术,采用面向对象技术构造了虚拟场景的树型层次组织,提出了基于三维地形的场景空间层次包围盒构造方法,基于空间层次包围盒进行快速可见性预判断和LOD层次计算,实现了一个基于微机平台的复杂场景实时生成系统,并应用于虚拟战场的实时仿真。

This paper discusses the key technologies for complex scene real-time rendering based on PC. Firstly using object-oriented structure to organize the virtual objects in the battlefield, then constructing the hierarchy bounding-box tree based on the 3D terrain of virtual battlefield. According to the hierarchy bounding-box tree, develops a visibility calculating method and a LOD calculating method. The result is a real-time rendering system for complex scene based on PC, and applied to virtual battlefield simulation.
