Approximating a Sine Wave with a Cubic Bézier Curve
07 Jan 2008, 04:44:00 PM
The standard cubic Bézier curve is given by P(t) = (1–t)3P0 + 3(1–t)2tP1 + 3(1–t)t2P2 + t3P3 To find an approximation of the sine curve given by y = sin(πx/2) over the interval [0, 1], set P0 to (0, 0) and P3 to (1, 1). Here are a few methods th ...
