The reflection operator is in charge of calculating what happens to each incoming lighting function and gives a certain output. Depending on which reflection operator you use, you can give the object a more matte feel or a mirror-like appearance. Since this operator is used for every single incoming light function and the entire world space, we have to make sure that this function is efficient and is able to be quickly calculated.
