WebBlinn-Phong is a slight adjustment of the Phong model you saw in the lighting section. It provides more plausible or realistic specular reflections. You'll notice that Blinn-Phong produces elliptical or elongated specular reflections versus the spherical specular reflections produced by the Phong model. In certain cases, Blinn-Phong can be more ... WebOct 3, 2005 · Keep in mind that Phong doesn't work well with anisotropic reflections though. Use Blinn or Ward in these cases. Also Ward seems to work somewhat better for metals. …
