[Paraview] vtkDiscreteMarchingCubes point/cell arrays from XML-PV plugin

[Joachim Pouderoux]

Hi Roman,

I guess we should add some SetName() calls in the code of
vtkDiscreteMarchingCubes.
Feel free to submit a merge request with this very small change.

In the meanwhile, what about adding a Programmable Filter on the output of
this filter and do something like:

inputpds = self.GetInput().GetPointData().GetScalars()

if inputpds != None:

  inputpds.SetName("PointScalars")


inputcds = self.GetInput().GetCellData().GetScalars()

if inputcds != None:

  inputcds.SetName("CellScalars")



Do not forget to check the "Copy Arrays" option for sure.

Best,

Joachim
