Hi Norman,
To set point data, you can first get the point data object with
vtkPointData* pointData = polydata->GetPointData();
Then you can add arrays to it:
vtkFloatArray* myArrray = vtkFloatArray::New();
myArray->SetName("myArray");
myArray->SetNumberOfComponents(1);
myArray->SetNumberOfTuples(polydata->GetNumberOfPoints());
// Set array elements here...
pointData->AddArray(myArray);
The same holds true for cell data, just replace PointData with CellData,
and set the number of tuples to the number of cells instead of the number
of points.
Hope this helps,
Cory
