I am attempting to access data arrays from my vtkDataSet objects.<br>vtkDataSet->GetPointData->GetScalars should be accessible for all vtkDataSet types, i believe.<br><br>my code:<br><br>vtkDataSet *output = vtkDataSet::SafeDownCast(
<br> outInfo->Get(vtkDataObject::DATA_OBJECT()));<br>outPD = output->GetPointData();<br>vtkDataArray *scalarArray = outPD->GetScalars();<br><br>In this case i have a vtkPolyData input. When i attempt to print the number of components, my program crashes without error:
<br><br>myOutputFile << scalarArray->GetNumberOfComponents();<br><br>Has anyone encountered this problem? any help apreciated<br><br>thank you<br><br>
