摘　　要：立即辐射度算法作为全局光照模拟的重要算法之一,在计算机图形学研究中受到广泛的关注,然而目前大部分基于立即辐射的算法都是离线渲染的。随着计算机硬件的发展,立即辐射度算法实时化已经成为一种趋势。通过图形渲染管线计算虚拟点光源,并用Lightcuts算法裁剪后的光源进行延迟着色光照计算,可实现性能较好的实时全局光照效果。As one of the most important algorithms for global illumination simulation, the instant radiosity algorithm has received widespread attention in computer graphics. However, most of the algorithms based on instant radiosity are currently rendered offline. With the development of computer graphics hardware, the real-time radiation degree global illumination algorithm has become a trend. Calculating the virtual point light through the graphics rendering pipeline, and using the light source that is cut by the Lightcuts algorithm for the deferred shading, which can achieve better real-time global illumination effects.
