Bézier curve
A Bézier curve is a parametric curve frequently used with computer graphics. It is a mathematical description of a smooth curve that is defined by representative points. They are visually intuitive to use in a software GUI (graphical user interface), because dragging a control point updates the curves in real time. As such, they are a fundamental tool in vector graphics, digital animation, and architectural design software. They are also used to create digital fonts, in file formats, such as Postscript and TrueType.
When multiple Bézier curves are joined together, they produce a Bézier spline. The spline pictured contains two Bézier curves, one at each endpoint.
