[Paraview] Resample with Dataset (vtkValidPointMask)

Wed Apr 21 12:34:24 EDT 2010

Dear David,
I have two data sets with 3d points and a scalar value coming from two CSV 
files and then I filter them through Table to Points, and then I apply the 
resample data set filter.

So basically the two inputs are Poligonal Mesh, see the attached pic.

Sincerely,
Luca
