[Paraview] 3D vector & contour plots from a set of scattered point

Thanks a lot Sven,
I could generate vector plots. Still trying to find a way to do 3D contour
plots for my scattered points. As you said I need to have a mesh and to
interpolate my scalar value to nodes of that mesh. Does anyone have an idea
to do that?
