[osg-users] Idea to implement a kind of 'rubber mode'

Well, Chris, thanks for the question. It shows that I was not precise enough.
Currently I'm drawing the black line on top of a quite complex background (light blue). And as a second item I draw the quad with the red frame showing the green symbol and having transparent colour in the background so the scene background hat visible and the black line.
My goal is to use the textured quad as a rubber and remove the black line but not the scene background like in symbol.png.

I hope that clarified it a bit more?!

Thank you!
