I was recently using an algorithm for determining control points for a bezier curve. You need 4 total points to accurately determine the curve, maybe there is a similar curve that apple is solving for? http://www.antigrain.com/research/bezier_interpolation/ http://www.antigrain.com/research/bezier_interpolation/ // Assume we need to calculate the control // points between (x1,y1) and (x2,y2). // Then x0,y0 - the previous vertex, // x3,y3 - the next one.
