Subject: [osg-users] picking/selecting invisible objects
I'd like to ask some hint on how to be able to pick/select invisible 3D
In my scene, I need to have a totally transparent object and, when the mouse
moves on it, it should reveal its presence, for example displaying a halo or

How can I pick such an invisible object?
Thank you. Best regards.
