Vtkprobefilter or vtkreslicer

Dear all

I want to reslice a 3d volume according to a curve. I compute the perpendicular every 2 points of the curve and i get this slice in the center position on the point of the curve.

I am using vtkreslice filter and it goes a bit slow but i have read abour this vtkprobefilter. Is it more efficient than the vtkreslicer?

The problem i have is that if i compute it many times every time i compute the new curve the vtk append returns a bad location memory. With the vtkpobefilter do i need the append? Or it includes all in the pipeline? Is it more efficient?
