Starting off, what is a Bezier Curve? It is a curve defined by 2 or more control points which determine how the curve looks. The first and last control points are, by definition, passed directly through while other control points (in the general cases) are simply moved towards and not directly through. This can all sounds little difficult to understand at first, so I will give you an interactive demo on what Bezier Curves look like and how they work. In the demo, the blue squares are the “hard” control points and the red circles are the “soft” control points. As you drag the control points around the screen you will see the curve change accordingly.
