[Paraview] PointPicker on 2D view for 3D point location

[Jérôme]

Hi,

I have to place interactively a point in a volume (medical image).
Today, I use the PointSource and move the cursor in the volume by
changing the current plane view (camera). this is not easy for the
user 'Lambda'. My question is :
Is it possible to use the 2D view, ie a slice-by-slice volume
visualization, and then click on the pixel of interest : it gives the
2D (eg. x,y) position, the depth (eg. z) being defined by the current
slice number ?

Thanks a lot !

Regards,
Jerome
