Dear VTK users

I asked similar questions few days ago... and now I
can extract a portion of surface from my marching cube
object.. 

what I did in tcl is as follows :

vtkSelectPolyData loop
	loop SetInput [skull GetOutput]
	loop SetLoop selectionPoints
	loop GenerateSelectionScalarsOn	
	loop SetSelectionModeToSmallestRegion; 


my question is I don't want to change the color of the
region within the loop..  all I want to do is
outlining the boundary with a visible polyline 

is it possible to do this?  thanks

Chris
