Hi,

you will need a vtkPropPicker.

to retrieve the image coordinate from the viewport coordinate I use (in
Python) this code
https://github.com/vais-ral/CILViewer/blob/master/ccpi/viewer/CILViewer2D.py#L608

as
position = interactor.GetEventPosition()
voxel = self.viewport2imageCoordinate(position)

I hope it helps a bit.

I know you think you understand what you thought I said, but I'm not sure
you realize that what you heard is not what I meant (prob. Alan Greenspan)
