WebThe Phong model sets the intensity of specular reflection as proportional to the angle φ between the viewing vector and the specular reflection vector: = × ×cosαφ Is I ks α= shineness exponent ks = specular reflectivity of material The Phong Specular Model = × ×cosαφ Is I ks α= shininess ks = reflectivity WebFigure 5: Phong vs Blinn-Phong With Varying Shininess Values. Both the Phong and Blinn-Phong reflectance functions cause a highlight to appear around the direction of reflection. Blinn-Phong has a fix that allows a near-diffuse disctribution at low shininess. Notice that at shininess 1 the Phong highlight would be invisible past 90° from the ... hierarchy in architecture

http://graphics.cs.cmu.edu/nsp/course/15-462/Spring04/slides/07-lighting.pdf WebBling-phong often uses the term shininess for the specular power. You essentially want to map a roughness of 0 to some very high shininess (say 10000) and 1 to some very low shininess. In the past, I've used: shininess = 100/ (500 * roughness + 0.01) and gotten pretty decent results. Nickmav1337 • 3 yr. ago WebPhong Shininess.
