[Insight-users] About seed point selection in interactive way

[Xiaopeng Yang]

Hi all,

 

I made a program to visualize CT image in 2D by VTI widget. I am trying to select seed points by clicking some position in the 2D CT image interactively. Anyone knows how to program this? Does VTK has function to get the coordinates of some point in CT image? What is the name of that function?

 

Thanks,

Xiaopeng Yang
