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.
