When you add lights to an axes, MATLAB® rendering software determines the effects these lights have on the patch and surface objects that are displayed in that axes. There are different methods used to calculate the face and edge coloring of lit objects, and the one you select depends on the results you want to obtain.
MATLAB supports two different algorithms for lighting calculations,
selected by setting the
of each patch and surface object in the scene.
This illustration shows how a red sphere looks using each of the lighting methods with one white light source.
