Description of the Spotlight's attenuation :
This program draws an array of spheres lit by a spotlight whose cone angle can be changed and which can be moved as well. The spotlight cone is shown by a wireframe. The spheres are colored using color material mode.

Future Enhancement of the Program :
1. We can remove the wire frame as light and give it a prope…
