paraview 3d interpolation

Hi

I am able to view a vtk file imported from gtass gis into paraview. Instead of interpolating a dataset of 180k points in a different software, i am wondering if the interpolation can be done directly in paraview. the data format is a csv with xyzp.
thanks
F

I would like to know what kind of interpolation algorithms are avilable in Paraview for 3d interpolation.
