Hi all,
I’m going to generate pointclouds from CSV with Programmable Filter.
On ParaView 4.1 or older, the script works:
from paraview.vtk.dataset_adapter import numpyTovtkDataArray as da
from paraview.vtk.dataset_adapter import vtkDataArrayToVTKArray as va
pdi = self.GetInput()
X = va(pdi.GetRowData().GetArray('x'))
Y = va(pdi.GetRowData().GetArray('y'))
Z = va(pdi.GetRowData().GetArray('z'))
pts = vtk.vtkPoints()
pts.SetData(da(hstack((X, Y, Z)), 'Points’))
But on 4.2 or newer, the script isn’t work:
from paraview.vtk.numpy_interface.dataset_adapter import
numpyTovtkDataArray as da
from paraview.vtk.numpy_interface.dataset_adapter import
vtkDataArrayToVTKArray as va
pdi = self.GetInput()
X = va(pdi.GetRowData().GetArray('x'))
Y = va(pdi.GetRowData().GetArray('y'))
Z = va(pdi.GetRowData().GetArray('z'))
pts = vtk.vtkPoints()
pts.SetData(da(hstack((X, Y, Z)), 'Points’))
The error message is as follows:
ERROR: In
/Users/kitware/Dashboards/MyTests/NightlyMaster/ParaViewSuperbuild-Release/paraview/src/paraview/VTK/Common/Core/vtkPoints.cxx,
line 193
vtkPoints (0x1199f3a60): Number of components is different...can't set data
How can I use SetData() method on latest ParaView?
