Point Picking PCLVisualizer - set manually window x,y

[clausmichele]

The PCLVisualizer let us pick a point using the mouse: is it possible to implement a point picking, setting the X,Y coordinates in pixel of the render window instead of using the mouse click event? I've already searched a lot, other people had the same idea but no one could realize it.

I know that the point picking with mouse click is available through VTK https://vtk.org/doc/nightly/html/classvtkPointPicker.html

Can someone suggest how to modify the function in order to set x,y and get the correspondent 3D point?

Any news in implementing a kind of ray tracing function to obtain this result?
