Class PhongMaterial

  • public class PhongMaterial
extends Material
    The PhongMaterial class provides definitions of properties that represent a Phong shaded material. It describes the interaction of light with the surface of the Mesh it is applied to. The PhongMaterial reflects light in terms of a diffuse and specular component together with an ambient and a self illumination term. The color of a point on a geometric surface is mathematical function of these four components.

    The color is computed by the following equation: 

    
 for each ambient light source i {
     ambient += lightColor[i]
 }

 for each point light source i {
     diffuse += (L[i] . N) * lightColor[i]
     specular += ((R[i] . V) ^ (specularPower * intensity(specularMap))) * lightColor[i]
 }

 color = (ambient + diffuse) * diffuseColor * diffuseMap
             + specular * specularColor * specularMap
             + selfIlluminationMap
    where lightColor[i] is the color of light source i,
    L[i] is the vector from the surface to light source i,
    N is the normal vector (taking into the account the bumpMap if present),
    R[i] is the normalized reflection vector for L[i] about the surface normal,
    and V is the normalized view vector.
