[vtkusers] Smoothing

[Amy Henderson]

You could probably accomplish what you want by assigning the scalar values 
to the points in your polydata instead of to the cells. Then color by point 
data instead of by cells. (This will happen by default unless you 
explicitly tell VTK to color by cell data.) By default, Gouraud shading 
(which does color interpolation between points) is used during rendering.
