WebDiffuse and Specular Reflection Parameter definitions. When a ray hits one surface, some part of the ray may be transmitted, some part is absorbed, and the rest is reflected (specular or diffuse). By defining the following parameters, the portion of each ray type can be characterized. α (absorptance) : Fraction of the incoming flux which is ... WebMar 4, 2016 · The specular_color is combined with a percentage of the surface’s diffuse color. This is the same idea we used in lesson 9.3, but this time we take a percentage of the diffuse color instead of the face’s color. Notice that the final color of a pixel is simply the sum of the ambient, diffuse and specular calculations.
