While vertex lighting may be sufficient for your lighting needs, there is nothing quite like the beautiful lighting experience that per-pixel lighting offers. Per-pixel lighting is an extension of vertex lighting. In stead of calculating the lighting value at each vertex, it is instead done at each pixel. The tutorial showcases a comparison of vertex vs per-pixel lighting and gives a straight forward approach to implementing per-pixel lighting using HLSL and a .fx file.
