介绍了一种计算复杂环境中漫反射和非漫反射表面间光相互反射的通用辐射度方法。与以前的辐射度方法相比，表面不再需要是完美的漫反射器和发射器。一个完整的，独立于观察者的描述光离开每个表面在每个方向的计算，允许动态序列的图像渲染几乎没有额外的计算每个图像。像“反射跟踪”这样的现象，反射跟随一个移动的观察者穿过镜面。次要光源，例如从镜子反射到墙上的聚光灯发出的光也被考虑在内。
A general radiosity method accounting for all interreflections of light between diffuse and nondiffuse surfaces in complex environments is introduced. As contrasted with previous radiosity methods, surfaces are no longer required to be perfectly diffuse reflectors and emitters. A complete, viewer independent description of the light leaving each surface in each direction is computed, allowing dynamic sequences of images to be rendered with little additional computation per image. Phenomena such as "reflection tracking", reflections following a moving observer across a specular surface are produced. Secondary light sources, such as the light from a spotlight reflecting off a mirror onto a wall are also accounted for.
