Survey of instant radiosity
立即辐射度综述*

In recent years, instant radiosity as an approach for real-time global illumination, which acquired more and more attentions to application study in the real-time realistic rendering, especially fited for real-time rendering of complex scenes on PC with current graphic hardware GPU. This paper gave a survey to instant radiosity, looked back to its development, analyzed its fundamental theory, took deeply apart to the state-of-the-art of its extensions and optimization. And provided a clear blueprint of the method and pointed out its further research issues in real-time global illumination.
