Bézier Curves
They make many things easier.
In many design programs, Bézier curves are one of the most essential tools. The concept is surprisingly simple: you pull the small handles extending from points on a curve, adjusting its shape to achieve the desired result — whether in graphics, animation, or even sound editing.
Most designers pick up this tool intuitively. Yet sometimes intuition alone isn’t enough to fully grasp how a curve behaves and how to manipulate it precisely to match your vision.
Wikipedia explains the mathematics behind Bézier curves and describes different degrees of curves. In practical design work, cubic Bézier curves are used most often — and designer Peter Nowell provides a very clear, visual explanation in his video. Watching it will give you a better understanding of how these curves operate and help you manipulate them with confidence and precision.
