摘要
基于OpenGL的PBuffer技术,将虚拟场景的后视镜场景和鸟瞰图场景实时渲染为动态纹理,将纹理映射到对应模型,最终实现了对后视镜和鸟瞰图的模拟.在鸟瞰图绘制中,对地形采用了基于Cg语言的凹凸纹理效果,进一步提高了系统的绘制效率.
Based on P-Buffer technology of OpenGL, scenes of rearview mirror and airscape are rendered in real-time as dynamic texture, and then mapped to the relevant model. For improving efficiency, bump mapping is used to render terrain in Cg language.
