Webb2 juli 2015 · The real importance of Phong shading is that it makes possible other features that rely upon a more accurate surface normal. So far in this article, you’ve seen shading that’s appropriate for diffuse surfaces. These are surfaces that are rather rough and dull and that tend to scatter light reflected off their surfaces. WebbThe term “ Phong shading ” was once commonly used to refer to what we now know as per-fragment (or per-pixel) lighting. That is, evaluating the lighting equation at every …
