[vtkusers] vtkPointCloudFilter GetPointMap

[Jakob Jungfels]

Hey folks,

I hope this is the correct place for this question:

I am using VTK 7.1.1 in Python to create 3D models from DICOM files and 
perform some operations on the models. Currently my goal is to use the 
vtkPointCloudFilter classes, mainly vtkRadiusOutlierRemoval and 
vtkStatisticalOutlierRemoval, to remove outlier points from my data. 
Now, the problem is, that I want to use the GetPointMap function. 
Unfortunately, while the algorithm works fine, the GetPointMap function 
does not. The result I am getting is a string, always looking similar to 
this "_000000004d6b5040_p_void". Some example code that I am using:

outliersRemoval = vtk.vtkRadiusOutlierRemoval()
outliersRemoval.SetInputData(self.tmpPolyData)
outliersRemoval.SetRadius(1.0)
outliersRemoval.SetNumberOfNeighbors(10)
outliersRemoval.Update()
print("Removed Points:")
print(outliersRemoval.GetNumberOfPointsRemoved())
outliers = outliersRemoval.GetPointMap()

Can anyone help me with this?

Kind regards,
