Global illumination is an important factor in creating realistic scenes and provides visual cues for understanding scene geometry. However, global illumination is very costly and only recently has it become viable to render scenes with global-illumination effects at interactive frame rates by exploiting the parallelism and programmability of modern GPUs.
