Just like how we have acceleration structures for looking at different parts of a scene, I wonder if there's a way to accelerate/estimate the number of simulated photons/rays a light source emits. It seems like there would be a lot of overhead to calculate all of the rays of a scene given multiple light sources.

How do we model in what direction light is emitted from surfaces?
