[Insight-users] A challenge in semi-automatic segmentation

[Luis Ibanez]

Hi Xiaopeng,

Please look at the code in IGSTK:

   IGSTK/Source/igstkView.cxx


Search for "m_PointPicker".

---

You will find the code at:

       http://www.igstk.org

IGSTK is based on ITK and VTK.


  Regards,


        Luis
