摘　　要：针对影响虚拟场景实时渲染速度与场景精细度的矛盾,研究了虚拟场景实时渲染的软件优化方法。对虚拟场景构建的设计阶段进行场景分割与预存储,对建模阶段进行模型与贴图的优化处理,对运行控制阶段进行可见性细节层次设置与多线程控制。使用这些优化方法后,在保持视觉效果的同时,有效降低场景的复杂度,减少硬件设备的负担,从而提高实时渲染的速度与交互操作的流畅性。With the contradiction between real-time rendering speed and the fineness of virtual scenes, some software optimization methods were investigated. Scene segmentation with pretreatment was used in the design of virtual scene, model and mapping were optimized in modeling and visible Level-Of-detail （LOD） with multithreaded control were used in contrelment. After using these optimization methods, the complexity of scenes and the burden of hardware are reduced effectively while maintaining visual effects, and the speed of real-time rendering and the smooth of interactivity are widely improved.
