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

[Voerman, L.]

Hi Christoph,
I can combine this with a scene that uses shaders without modification. If
that's not working for you I don't understand why.
Using the depth buffer to block further rendering will need the
GL_DEPTH_TEST to be active, did that change for your shader/fixed scene?
