Some Thoughts on the Fresnel Term Naty Hoffman The Fresnel term would appear to be the best-understood part of the microfacet model --- one can simply use the original equations, or an approximation (usually Schlick's) if computation cost is at a premium. However, in this talk, we will show that all is not as it seems, and that even the humble Fresnel term can hold some surprises. This talk builds on a previous presentation at the 2019 Eurographics Workshop on Material Appearance Modeling [Hof19], extending it into a more comprehensive overview.
