[Paraview] Reconstruction of surface data from point cloud.

[Feijoo, Gonzalo]

Hi, David,

Many thanks for the quick reply! Somehow that did not work. The values are still not being passed to DataArrays. I will look into the documentation to see if there is anything else that can be used.

Best,

Gonzalo

Try throwing in a call to vtkContourFilter->ComputeScalarsOn() like so.

subf2.SetInputConnection(subf1.GetOutputPort())

subf2.Update()

pdo =  self.GetPolyDataOutput()

pdo.ShallowCopy(subf2.GetOutput())


The default behavior is to not pass arrays through, which is right in the fairly common case (but not common enough to make it the default in my opinion) of a single isocontour from a single array. In that case the values would all be the same.
