The reason I ask is that it seems like there is no vtkAppendUnstructuredGrid
or vtkAppendPointSet, only vtkAppendPolyData. Is there a reason for this?
The output should be the same type as the inputs if the input types are all
the same. If the inputs are different types, the output should be the "most
general" type of vtkPointSet.

Does something like this already exist? Or should we add it?

Thanks,

David
