I see here that increasing the power on the cos term (p) makes the value decrease much more sharply as the angle increases. The slide says that this narrows the reflection lobe? What does this mean? And what effect does this have on the final render?
According to lecture, I believe the reflection lobe is like the space where light will be reflected relative to the tangent line. When it gets narrower, the reflection gets more "concentrated"
Regarding the question above^^: The reflection lobe is that bright mirror like spot on a surface. Also, does decreasing p to be fractional cause the reflection lobe to be very spread out across surface?
