... Ok.... I think this is rather a dependance with the version of vtk.
Doing this in a programmable filter in paraview
from paraview import vtk
i = self.GetInput()
o = self.GetOutput()
b = i.GetBlock(1)
c = vtk.vtkArrayCalculator()
c.SetInput(b)
c.SetFunction('1.4')
c.SetResultArrayName('test')
c.Update()
print c.GetOutput().GetPointData().GetArray('test').GetTuple1(1)
it prints 1.0
While doing this in the python console, il prints 1.4
... I think I should use pvpython, in order to work with the same version of
vtk ...
