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

[Nima Emadi]

Dear all,
I would like to generate 3D vector plots from a set of scattered data in
space (an ASCII file with x,y,z,u,v,w). I guess this should be rather
simple, but later on I want to generate 3D contour plots out of my data
(e.g. having contours based on the value of u^2+v^2+w^2 at each point).
Since I just have the value on scattered points in space, making those
contours will probably require extrapolation of my data to nodes of a
(regular) mesh. My question is that, how can I do those plots? with which
format should I import my data? Is paraview able to make contour plots with
scattered data points in 3D?

Thanks,
Nima
