If you write your own intersection visitor or extend one then YOU can do want when your visitor hits a osg::Switch node

Hi Robert. What I mean is: I have a scene made of 3 spheres, each attached under a different switch node. The first two spheres are visible (their switches are turned on), while the third is not (so its switch is turned off). I would like to select also the third sphere (imagine for example that I want the third sphere to be visible only when the mouse is over it), even when it is invisible.

Hi Gianluca, What do you mean by "select" and object? What type of object? Robert.
