[vtkusers] Smoothing

[Ted Vu]

so instead of doing

Mapper->SetScalarModeToUseCellData();
myPolyData->GetCellData()->SetScalars(myFloatArray);

I should do
myPolyData->GetPointData()->SetScalars(myFloatArray);

??
But won't I just see a bunch of particles then? i.e. a bunch of colored 
dots??  How do I get it to interpolate between teh dots and fill in the 
whole polydata?
