Hi,
I forgot the "e" for ColorAttributeType (and not ColorAttributType)
stupid mistake.
thanks anyway

Hi,
I had a similar problem a while back. Try applying the
CellDataToPointData filter before the cut filter.
Hope it works,
Peter.

Hello,
I'm starting to use paraview in script mode using pvpython.
I succeeded to load my data and to make a representation of my U CellData
fields using a Cut() filters.
This works fine.
But now I would like to have the magnitude of my U field for PointData and
I'm stuck in the use of CellDataToPointData filter.
The following script only give me a blank field for my Cut() when passing
trough the CellDataToPointData filter.
Surely I forgot something (interpolation, choice of component of field), but
even by looking at the dir() and help() I didn't manage to have my field
interpolated at points and represented in colors.
Thanks for anyone who could give me hints to solve this problem.
python script :
con = servermanager.Connect()
vtkf =
servermanager.sources.LegacyVTKFileReader(FileNames="VTK\\design71_1.vtk")
vtkf.UpdatePipeline()
implicit_functions = servermanager.createModule("implicit_functions")
plane = implicit_functions.Plane()
plane.Origin = [0,0,-0.5]
plane.Normal = [0,0,1]
zcut = servermanager.filters.Cut()
zcut.Input = vtkf
zcut.CutFunction = plane
zcut.ContourValues = [0]
zcut.UpdatePipeline()
pdata = servermanager.filters.CellDataToPointData(Input=zcut)
pdata.UpdatePipeline()
view = servermanager.CreateRenderView()
view.ViewSize = [1440, 900]
rep = servermanager.CreateRepresentation(pdata,view)
lt = servermanager.rendering.PVLookupTable()
rep.LookupTable = lt
rep.ColorAttributType = 0
rep.ColorArrayName = 'U'
lt.RGBPoints = [0, 0, 0, 1, 15.0, 1, 0, 0]
lt.ColorSpace = 1
view.ResetCamera()
camera = view.GetActiveCamera()
camera.SetPosition(0.85, 0, 8.55)
camera.SetFocalPoint(0.85, 0 , -0.5)
view.StillRender()
view.WriteImage("test.png","vtkPNGWriter", 1)
