Basic Shapes, Continued
Cones appear triangular in shape but, have a circle or ellipse as a base.
Lines converging to some point above or below the base determines the
height of a cone. Shading defines the roundness of cones.
Figure 3-16 shows a basic cone.

Figure 3-17 shows how shading changes the cone into a tree.
