You're almost there.

x-y-z >> vtkPoints >>             \
                                   - vtkPolyData
attribute-per-point >> vtkScalars /

vtkPoints *points
vtkScalars *scalars

Step 1 with (vtkPolyData var.)->SetPoints (points);
Step 2 with (vtkPolyData var.)->GetPointData()->SetScalars (scalars);

Now you have a vtkPolyData which can go through the pipeline.
