[vtkusers] Regarding vtkSeedWidget

[Xiaopeng Yang]

Hi, Thank you very much for your help. I saw that you defined N seedwidgets.
Did you define one seedwidget for one slice or one seedwidget for one seed?

 

Thank you,

Xiaopeng

You can also use a "vtkConstrainedPointHandleRepresentation".

 

See InitializeSeedWidget() in
https://github.com/gofigure2/GoFigure2/blob/master/Code/GUI/lib/QGoImageView
.cxx

 

Hope it helps,

 

Nicolas

In my CT viewer I use a 2d representation for the handle widget and
save/restore the seeds on each change of slice.
