[vtkusers] GetCellPoints

[Patrick Lowry]

VTK Users,

I would like to be able to choose a specific connected polygon region 
based on its scalar value.  I am using vtkCellPicker to pick a cell 
on a polygon generated from the connectivity filter to get the 
cellid.  I would then like to get the point ids so that I can get the 
scalar value and then use that with the connectivity filter again to 
select the specific region.  I am coding in Tcl/Tk.  Following is an 
extract of the code.  I suspect it is simple syntax but I can't 
figure it out.  Any help would be appreciated.

Thanks,
Patrick

   vtkConnectivityFilter connect
     connect SetInput [thresh GetOutput]
     connect SetExtractionModeToAllRegions
     connect ColorRegionsOn
     connect Update
   vtkGeometryFilter geomFilt
     geomFilt SetInput [connect GetOutput]
.
.
.

vtkCellPicker picker
   picker SetEndPickMethod annotatePick

proc annotatePick {} {
     set cellid [picker GetCellId]
     set connscal [[geomFilt GetOutput] GetCellPoints $cellid] ; # 
Wrong syntax?!!!
}
