Thanks for the reply. Don't know what I said to deserve the introductory put-down, but anyway if my only reasonable choice is to

So I'm not sure how using just shaders in my program is relevant. Aren't there default ones? Do I need to enable some as a replacement for where I used to glBegin/End? If so, where is the best place to start reading about it? I did build the latest stable OSG from source, but I would appreciate if you could point to the appropriate documentation for "building against GLCore from scratch". Hopefully it's just some magic -D compiler options. At present, I am actually trying a work-around which is to render to a texture or pbuffer, with a context created by OSG, then basically copy that over to the normal 2D engine like Cairo. Inefficient, but it may work OK for us since the 3D display is not full-screen.
