[osg-users] How to use frame buffer object in existing (not osg) window and pipeline.

[Han Hu]

Hi Robert,

Thanks for your suggestion, I understand  the bettter way is to use osg in all the pipeline. But the ugly fact is that I have to use existing pipeline and inject the view.frame() inside a fbo binding, and hope osg will draw the things onto the fbo texture and depth. Because I can't make others change to osg. 

And the reasons I have to inject osg into existing pipeline is that I have to load an pagelod data into the scene (some osgb data). And I have successfully do this in the viewerglut example. Otherwise I have to reinventing the big wheel .

Thank you!

Cheers,
Han
