The reflection model known as the ray method, is based on the assumption that incident light is specularly reflected by the local tangent plane on the surface.
For textured (and hence rather rough) surfaces, the measured gloss contains specularly reflected light as well as a significant contribution of the diffuse reflectance.
Gloss is defined as the optical property that measures the ratio between specularly reflected intensity and the incident light intensity.
However, if the specularly reflected beams are not picked up, it may be more difficult to achieve the same accuracy.
