Hi, Does anybody have an example how to use vtkNetCDFReader class ? Should this work? vtkSmartPointer<vtkDataSet> netcdf_reader() { vtkSmartPointer<vtkNetCDFReader> reader = vtkSmartPointer<vtkNetCDFReader>::New(); reader->SetFileName("example.nc"); reader->UpdateMetaData(); return vtkImageData::SafeDownCast(reader->GetOutput(0)); }
