[Suppose we want to draw a complicated curve. We could use a high-degree Bézier curve, but there are several problems with this approach:
We cannot represent cusps (well, not easily, anyway).It is expensive to evaluate high-degree Bézier curves.A large number of control points may be required to get the shape we want.The effect of modifying middle control points is diffuse, and they become less useful as shape parameters.]
