<DIV style="DISPLAY: block; FONT-SIZE: 12px; FONT-FAMILY: Arial">
<P>Hi,</P>
<P> </P>
<P>I have a problem with the cell picking in Java.</P>
<P>When I click with the mouse, I want to know the cell Id, but I often get a
wrong result.</P>
<P>I tried with different tolerance values but it's still the same thing.</P>
<P>If someone know how to use vtkPicker with Java. Thank you in advance.</P>
