Both topics are covered in this chapter.

We discuss ambient and directional occlusion and methods for rendering global illumination effects on diffffuse and specular surfaces, as well as some promising unifified approaches.
第11章，全局照明。模拟光与场景之间的多次交互的算法进一步提高了图像的逼真度。我们讨论了环境和方向遮挡以及在散射和镜面表面上呈现全局照明效果的方法，以及一些有前途的统一方法。
