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.

Ok

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.

Ah ok

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.

It would be cool to have hierarchical bundles edges in Roassal.
