reflection (matte). It's an important part of achieving realism in materials and
lighting. Reflection occlusion also helps out with grounding the object being re-
flected into the scene at the contact points, as we can see in Figures 4.2 and 4.3.
It's an important part of our visual understanding of reality and it shouldn't be
