Web7.2.2 Specular Reflection and Phong Shading. To add specular lighting to our basic lighting model, we need to work with the vectors R and V in the lighting diagram. In perfect specular reflection, the viewer sees a specular highlight only if R is equal to V, which is very unlikely.But in the lighting equation that we are using, the amount of specular reflection … WebSpherical reflection (or environment) mapping (SEM) is a fast way to fake the specular term of the lighting equation, and for specific cases, to fake lighting altogether. This technique has been popularised by software like …
