[vtkusers] vtkPointPicker, coordinates?

[George Kamucha]

Hi all,
I am playing around with vtkPointPicker inorder to obtain the coordinates of particular points on my data set. It is really a game because the coordinates I am getting are a bit far from
what I was expecting. I am really confused...Hey, what kind of coordinates does GetPickPosition() return, global or somehow unknown? Here is a part of my snippet (tcl), may be something is
terribly wrong with it?

......

vtkPointPicker pointPicker
    pointPicker SetEndPickMethod pickBabie

proc pickBabie {}  {
    ......
    if {[pointPicker GetPointId] !="-1"} {
         set pointPos [pointPicker GetPickPosition]
         puts "\nPicked Point  is at  \$$pointPos"

         } else {
         puts "\nNo Point was picked here!!"}
  }


Best regards

George
