[vtkusers] smooth part of surface (polydata)

[mikewithascarf]

How would I go about smoothing only a part of a surface (vtkpolydata)? I have
a surface where there are bumps, which I know the centers (x,y,z) and
approximate radius of. I only want to smooth these bumps, and leave the rest
of the surface untouched. Is there perhaps a way to specify a region for
vtkSmoothPolyDataFilter to act on? 

Any help is appreciated!
