[vtkusers] Correct way to save the output of vtkProbeFilter

[Siming Bayer]

Dear all,

Could somebody please provide a correct way to save the output of vtkProbeFilter?

I used the following code to save it as vtkStructuredGrid (probe ist a vtkProbeFilter)
vtkSmartPointer<vtkProbeFilter> probe = vtkSmartPointer<vtkProbeFilter>::New();
…...

//save the output of probefileter as .vtu file
vtkSmartPointer<vtkStructuredGrid> sgrid = vtkSmartPointer<vtkStructuredGrid>::New();

sgrid->SetDimensions(256, 256, 256);

sgrid->SetPoints(probePoints);

unsigned int numberOfArrays = probe->GetOutput()->GetPointData()->GetNumberOfArrays();

std::cout << "Copying arrays:" << std::endl;

for (unsigned int i = 0; i < numberOfArrays; i++)

{

std::cout << "\t" << probe->GetOutput()->GetPointData()->GetArray(i)->GetName() << std::endl;

sgrid->GetPointData()->AddArray(probe->GetOutput()->GetPointData()->GetArray(i));

}

std::cout << "Writing .vts output" << std::endl;

vtkSmartPointer<vtkXMLStructuredGridWriter> sWriter = vtkSmartPointer<vtkXMLStructuredGridWriter>::New();

sWriter->SetFileName("test.vts");

sWriter->SetInputData(sgrid);

sWriter->Write();


But I got errors when I try to load the .vts file in paraview:

ERROR: In C:\bbd\7cc78367\build\superbuild\paraview\src\VTK\IO\XML\vtkXMLStructuredDataReader.cxx, line 360

vtkXMLStructuredGridReader (000000000BA5C060): Error reading extent 0 255 0 255 0 255 from piece 0

ERROR: In C:\bbd\7cc78367\build\superbuild\paraview\src\VTK\IO\XML\vtkXMLDataReader.cxx, line 443

vtkXMLStructuredGridReader (000000000BA5C060): Cannot read point data array "position" from PointData in piece 0. The data array in the element may be too short.


What do I do wrong?

Thanks!

best,
Siming
