Bézier Curves

Bézier curves are used all the time in computer graphics and animation. They allow you to make complex vector shapes and motions while only using a very small amount of data. Instead of having to plot every point of a curve, a Bézier curve can be produced from a simple equation. All you need is two points for the beginning and end of he curve, and two extended handles that you can stretch to change the angle and intensity of the curve. It is very simple to use these curves, and you can easily achieve the curves you want with trial and error, but it is hard to understand how they work without a good explanation. I found an extremely simple and satisfying video explanation of how Bézier curves work. This might help you in the future if you work with Bézier curves, and if not, it's still entertaining for anyone who has no idea what a Bézier curve is and doesn't care either.
