WebSep 5, 2016 · 1. Four points are required to uniquely describe a cubic curve (the first article you've linked covers that case). You have more than four points so are unlikely to get a perfect fit - some kind of compromise or trade-off will be required. Welcome to the black art of numerical optimisation! WebJun 17, 2012 · The math here is not difficult at all. Bezier cubic is a (duh!) a cubic polynomial, evaluated from t=0 to t=1 between the left and right end point. Two other “knot” points control the shape of it in between. The whole point of finding the smooth spline is satisfying two requirements: The individual splines need to “touch” at end points WebBezier.quadraticFromPoints (p1,p2,p3,t) / Bezier.cubicFromPoints (p1,p2,p3,t,d1) Create a curve through three points.
