Click keys 1-5 to change the map. Move your mouse around to control the light. If its laggy refresh. The light represent a large object such as the sun, to show that not all light is depleted when it gets blocked by something, like how on your shadow you can still see the ground and it's not just black, which is why it doesn't appear black, unless multiple objects are in the way. The thicker and bigger an object is the more light it absorbs, and the more light it blocks, resulting in darker shadows for different sized objects.
