Where is the code? In RequestData()?<br><br>GetFieldData() != GetPointData() + GetCellData()<br><br>FieldData is a set of arrays associated with the whole data object and not necessarily with points or cells. This may be some meta-data like integral of pressure for example. Or anything else your heart desires :-)<br>

Right, vtkDataSetAlgorithm::RequestDataObject() seems to do the job but now I have another problem: the point data are no longer copied to the output.<br>Here is my code, what is wrong?<br><br> // get the output<br> vtkInformation *outInfo = outputVector->GetInformationObject(0);<br>
vtkDataSet *output = vtkDataSet::SafeDownCast(outInfo->Get(vtkDataObject::DATA_OBJECT()));<br><br> // pass all associated data to output dataset<br> output->CopyStructure(this->input);<br> output->GetPointData()->PassData(this->input->GetPointData());<br>
output->GetFieldData()->PassData(this->input->GetFieldData());<br><br>and another question: is GetFieldData() the same as GetPointData() + GetCellData() ?<br><br><hr>Date: Fri, 19 Feb 2010 06:38:50 -0500<br>

My problem is as follow: I am writing a vtkDataSetAlgorithm filter and I need to create the ouput dataset, which must be of the same type as the input.<br>Is there a one-line way to do it, ie avoiding if (input->IsA("vtkPolyData") output=vtkPolyData::New(); else if ... ?<br>
