Apply Phong shading to a graphics primitive:

Apply Phong shading to a plot:

Apply Phong shading to a chart:

Apply Phong shading to a 3D object:

Summary box:

PhongShading with no arguments uses similar calculations as the default system shader:

Attenuate all light from the surface by a scaler value:

This is equivalent to specifying each attenuation factor explicitly:

Attenuate the diffuse light, setting other attenuation factors to zero:

Attenuate the specular light, setting other attenuation factors to zero:

Attenuate the ambient light, setting other attenuation factors to zero:

PhongShading works with all types of lights:

Use colored lights:

The specular percentage only applies if the Specularity directive has been specified:

The ambient percentage only applies if an AmbientLight is has been specified:

Show interior normals interpolated from vertex normals:

Triangle with identical vertex normals:

Triangle with a different normal at each vertex:

PhongShading can be separated into individual components for diffuse, specular and ambient lighting:

These components are summed to achieve the final result:

PhongShading performs the individual calculations and summation by default:
