did you try setting the tolerance to zero? it shouldn't pick something that far away with a small enough tolerance.<br><br>Note also that I wrote in a previous email how scaling transformations seems to screw up the picker a bit.<br>

Thanks Dominik,<br>
<br>
I adjusted the tolerance, but it doesn't work.<br>
<br>
I click with the mouse just over the line neart the text (124) that you can see in the screenshot. The selected point is very far away because the other point is closer to the 3D ray used by vtkPointPicker. The problem is that in the screen, the point over the mouse pointer is the closest but using the ray in the 3D world, the other point is closer to the ray.<br>
<br>
I can send you the TCL application and the input data so you can try it if you want.<br>
<br>
Thanks!<br>
