VTK legacy format is a bit confusing because it follows old VTK terminology. You seem to be setting the FieldData for the cell data. You need to set DataObject's FieldData. Here is an example:
# vtk DataFile Version 3.0 vtk output ASCII DATASET POLYDATA FIELD FieldData 1 aFieldArray 1 1 float 2 POINTS 5 float 0 0 0.5 0 0 -0.5 0.5 0 -2.18557e-08 -0.25 0.433013 -2.18557e-08 -0.25 -0.433013 -2.18557e-08 POLYGONS 6 24 3 2 3 0 3 3 4 0 3 4 2 0 3 2 1 3 3 3 1 4 3 4 1 2 POINT_DATA 5 SCALARS Elevation float LOOKUP_TABLE default 0.675676 0.243243 0.621622 0.540541 0.216216 On Sun, Feb 28, 2010 at 6:11 AM, Fred Fred <[email protected]> wrote: > Hmm, I tried it without success: > > FIELD FieldData 1 > FEmethod 1 1 string > Lagrange > > yieds to: > > ============================================ > ERROR: In /usr/local/ParaView3/VTK/Filtering/vtkDataSet.cxx, line 439 > vtkPolyData (0xae3eac0): Cell array FEmethod with 1 components, has only 1 > tuples but there are 4 cells > > ERROR: In /usr/local/ParaView3/VTK/Parallel/vtkPDataSetReader.cxx, line 921 > vtkPDataSetReader (0xa5d5c60): Attribute Mismatch. > > ERROR: In /usr/local/ParaView3/VTK/Filtering/vtkExecutive.cxx, line 757 > vtkCompositeDataPipeline (0xa5d6420): Algorithm > vtkFileSeriesReader(0xa5a2600) returned failure for request: vtkInformation > (0xae3e650) > Debug: Off > Modified Time: 97070 > Reference Count: 1 > Registered Events: (none) > Request: REQUEST_DATA > FROM_OUTPUT_PORT: 0 > FORWARD_DIRECTION: 0 > ALGORITHM_AFTER_FORWARD: 1 > ============================================ > > > while: > > FIELD FieldData 1 > FEmethod 1 4 string > Lagrange Lagrange Lagrange Lagrange > > works! > > > Date: Tue, 23 Feb 2010 17:07:02 -0500 > > > Subject: Re: [Paraview] How to get back the first line of a VTK legacy > file > > From: [email protected] > > To: [email protected] > > CC: [email protected] > > > > Yes, in field data, the number of tuples doesn't have to match the > > number of points or cells, so you can have arbitrary length arrays. > > > > Utkarsh > > > > On Tue, Feb 23, 2010 at 4:51 PM, Fred Fred <[email protected]> wrote: > > > Does it mean that a field data array store only the variable once for > all > > > the dataset?
