Question

The color value of an individual pixel in Phong illumination is determined by different parameters: ●light colors (c, for specular and diffuse light, ca for ambient light) high-light color cp and surface color crspecular coefficient n .specular coefficient p. We consider a sphere with constant surface color cr=0.5 and otherwise varying lighting properties. For simplicity,all colors are in grayscale. Match each of the spheres (a)-(d) in Figure 2 with one the settings (1)-(6) below.

(2) Ca = 0.0,C₁ = 0.5,Cp = 0.5,p=1.5 (1) Ca = 0.5,C₁ = 0.0,Cp = 0.0,p = 1.5 (3) Ca=0.5,CI= 0.0,=Cp = 0.5,P = 8 (4) Ca = 0.5,C₁ = =0.5,Cp = 0.0,P = 32 (5) Ca = 0.5,Cl = 0.5,Cp = 0.5,p = 8 (6) ca = 0.5,CĮ = 0.25,Cp = 0.25,P = 32
