[vtkusers] Retry - vtk4.0 regen pipline.

[D.M.P.Davies]

Having had no answer to my earlier question I'll retry.

My tcl/tk program works under vtk4.0 with the necessary  changes to
vtkFloatArray's.
However ; having changed values in a method in any object/filter/mapper
I can't seem to get the changes displayed

with modified or Updated.

Please - what to I need to do to rerun the modified pipeline.

Many Thanks

Dave Davies
