Extracting paraviw data into arrays


I have recently used the glyph filter to represent a 3D deformation image. The Deformation is presented with Arrows.
I want to use the representation post-processed in Paraview, and to extract the initial and terminal coordinates of each arrow (Xi,Yi,Zi, Xt,Yt,Zt).

I have tried to ‘save data as csv’ but when I’m trying to quiver-plot the csv data I get a completely different representation from the one I have in Paraview.

Is there a simple way it can be done? maybe by extracting the coordinates out from the vtk file (enclose) ?

def_glyp.vtk (93.1 KB)

any hint is welcomed
Thanks !
