[Paraview] problems of changing text file to vector image

[feng yang]

hello , everyone,
Does anyone know how to change the .txt file into .vtk file(or other files
whose pixel type is a vector). Now I have a text file, in which are the
point coordinates and its new position(so we know its diplacement), and i
want to change this txt file into and image file .Because I want to do the
Linear interpolation of the displacement,but it need a image file as input.

Thanks for your advice!
