vtkLabeledDataMapper (01684DB0): Need input data to render labels<br>
<br>
Now I would of thought that line<br>
filter->GetOutput()->GetPointData()->SetScalars(scalars);<br>
has set the scalar values. Am I wrong??? is there some funny referencing
going on here???<br>

When a filter executes it initializes its output. You are setting scalars
on an output, then the pipeline executes and throws it away. You can
either a) do a manual Update() on the filter prior to setting the
scalars, or b) do it the "correct" way and use a filter to
insert the scalars into the data. For example, use
vtkProgrammableAttributeDataFilter, or create a dummy dataset (with the
scalars inside) and use vtkMergeFilter, or roll your own filter.<br>
