Developed by the French mathematician Pierre Bézier, a Bézier curve is a mathematically defined curve used in two-dimensional graphic applications. The curve is defined by four points: the initial position and the terminating position, and two separate middle points. Bézier objects can be modified by moving these points with the mouse.
贝塞尔曲线是一种使用数学方式定义的曲线，由法国数学家皮埃尔·贝塞尔提出，在二维图形应用程序中使用。这种曲线由四个点定义：起点、终点和两个独立的中间点。使用鼠标移动这些点可以修改贝赛尔曲线对象。
