7.2 OpenGL Materials7.2.2 PhongThe Phong material has a simple phong shading model, which does not support anyHDRI lighting. The simple material is only visible, when it is light by standard lightsources.» Ambient Sets the Phong’s ambient light reflection color.» Diffuse Sets the shader’s diffuse reflection color. This is the color the shaderadopts, when the light reflection of the surface is spread to many directions.» Transparent Sets the surface’s transparency.» Specular Sets the shader’s color for specular reflection. Specular reflection behavioris described by the law of reflection which states that the direction ofincoming light (incident ray) and the direction of outgoing light reflected (reflectedray) form the same angle with respect to the surface normal, thus the315
