Cubic Bézier curve with four control points The basis functions on the range t in [0,1] for cubic Bézier curves: blue: y = (1 â t)3, green: y = 3(1 â t)2t, red: y = 3(1 â t)t2, and cyan: y = t3. A Bézier curve (/ËbÉz.i.eɪ/ BEH-zee-ay,[1] French pronunciation: [bezje]) is a parametric curve used in computer graphics and related fields.[2] A set of discrete "control points" defines a smooth, continu
