[vtkusers] Emulating Paraview 5's Interactive Select Points in VTK

[Evan Kao]

Hello all,

I'm trying to emulate Paraview 5's Interactive Select Points feature in VTK
by constantly monitoring the 'MouseMoveEvent' and obtaining the closest
point on the desired actor.  However, I run into some severe "jitteriness"
as seen in this video <https://www.youtube.com/watch?v=iXAhbjBCve4> (the
marker is represented by a green sphere).  In constrast, the marker in
Interactive Select Points mode in Paraview is predictable and steady.

What can I do to better replicate Paraview?

Thanks,
Evan Kao
