Move spline knot in local space
i am stuck moving spline knots (vertex) in local space.
i use "getKnotPoint [...]" and "setKnotPoint [...]" functions to get and set knot position but the point3 values are in current working coordinate system.
how can i (relative) move a knot in local space in the desired axis by a specified value?
any hint into the right direction is really appreciated.
thanks in advance
