Drawing with quadratic curves

A quadratic curve is a curve that has one control point. Consider the case when creating a line, we draw it between two points. When we want to create a quadratic curve, we use an external gravity controller that defines the direction of the curve while the middle line (the dotted line) defines how far will the curve reach.

Keynotes:

• Adding a control point to create curves.
• Understanding how to use the control point.
• Drawing an eye.
