To construct a circle, it is necessary to use compasses, or to construct a square, in more detail in this lesson. The light source to be in the top left corner, we set directing from it and we draw a shadow from a sphere. We draw a curve on a sphere which defines a dark site.

We put shadows.

We add a shadow and lighter tone a reflex (part of a shadow which is lightened by reflection from other surface).

We add a saturation and penumbras.

We continue to add light shadows on a light site of a sphere on which light falls.

We add shadings.

We shade for smoothness of object.
