It is interesting to see how given an amount of irradiance arriving at a point in a direction, we can calculate the irradiance exiting the point as well as the direction from the reflection function and the property of the material!

It's important to note that the differential exiting radiance has a "shorter" arrow, likely to represent the concept that light energy will decrease at each surface reflection
