Customary Pipeline updating the view in an arbitrary orientation

Dear all,

I have created a reslice getting the slices according to the perpendicular of a curve. But i need to call this function everytime that the spline of the curve is moved by the user.

Is there any way to create a vtk pipeline so that the call to the view update according to the new spline position is performed automatically?. Instead of calling this function everytime in the spline callback “execute”?

Thanks in advance
