<p class=MsoNormal>Hi Xiaopen,<br>
<br>
Capture the "EndPickEvent" with an Observer,<br>
and in the execute method of the observer,<br>
extract the coordinates of the point with code<br>
similar to:<br>
<br>
double data[3];<br>
picker->GetPickPosition( data );<br>
<br>
itk::Point< double, 3 > pickedPoint;<br>
pickedPoint[0] = data[0];<br>
pickedPoint[1] = data[1];<br>
pickedPoint[2] = data[2];<br>
<br>
<br>

See the example:<br>
