WebFeb 5, 2016 · The Blinn-Phong model is originally proposed to speed up the computation of the Phong model. It is the default shading model in OpenGL for its efficiency. … WebIn the blinn-phong reflection model, the variable that represents a material's glossiness is the specular exponent. So I'm thinking that the point of having a roughness map is to vary the specular exponent per-pixel, but it's not clear to me how one goes from a sampled value ranging from [0.0, 1.0] to an exponent value.
