Shadows
Shadows are the darkened areas that appear on a surface when an object gets
in the path of a light source. Shadows are cast onto the area of a surface that
doesnt directly receive light. Shadows ground the objects in your scene and
aid in defining their three-dimensional appearance. Shadows can add drama
to your scene.
Next, you create a shadow on the floor from the light cast by the spotlight.

the spotlight earlier in the lesson.
