Hi There are more than simply linear, quadratic and cubic Bezier curves. In fact, as you can have as many control points as you wish, you can have a Bezier curve of any order. But what I was calling RadialBezierCurve was a kind of strategy, I mean I have an abstract class which knows how to compute a curve, but I still have to choose my control points so I was thinking to create different subclasses whose role is to know what are their control points : - The radial one choose its control points within the same radius as its source and its target. I wanted to create an ortoVertical and an ortoHorizontal whose control points would have been computed differently, so that we could use Bezier curve for regular tree too.
