Reflectance function
Web7. okt 2016 · The Lambertian reflectance is simply the Cosine of the angle between light direction and surface normal and ranges from 0 (no light hitting the plane) to 1.0 (all light hitting the plane). Note Cosine (90) = 1. Cosine (0) = 0, hence called Cosine law (Lambertian reflectance). Share Improve this answer Follow answered Oct 10, 2016 at 13:27 lfgtm WebReflectance (R) R Reflected Power / Incident Power rr ii IA IA Because the angle of incidence = the angle of reflection, the beam’s area doesn’t change on reflection. Also, n is the same …
