Class Bezier


  • public class Bezier
    extends java.lang.Object
    Interpolates given points by a bezier curve. The first and the last two points are interpolated by a quadratic bezier curve; the other points by a cubic bezier curve. Let p a list of given points and b the calculated bezier points, then one get the whole curve by: sharedPath.moveTo(p[0]) sharedPath.quadTo(b[0].x, b[0].getY(), p[1].x, p[1].getY()); for(int i = 2; i < p.length - 1; i++ ) { Point b0 = b[2*i-3]; Point b1 = b[2*i-2]; sharedPath.curveTo(b0.x, b0.getY(), b1.x, b1.getY(), p[i].x, p[i].getY()); } sharedPath.quadTo(b[b.length-1].x, b[b.length-1].getY(), p[n - 1].x, p[n - 1].getY());
