I've done this approach in the past in other apps, and I always found weirdness lurking in the non-visible windows. Especially as MSWin and Linux windows managers evolve, there was a tendency for them to 'find' my non-visible windows and list them in ALT+TAB or other task/window displays. > I do agree with J-S, I think you need to have a context current to something. > Since the > calling app appears to already have a context current to a visible window, it > seems like > the best solution would be for your code to bind the FBO, render to texture, > then unbind > and return to the calling app -- all while the callng app's context is > current to its > visible window. This would be smart, but I'm loathe to encourage any cross-contamination between the existing context already bound to a visible window. Again, not for any specific reason, just a "here there be dragons" kind of gut instinct. Thanks everyone for the input. The PBuffer approach I've already gotten to work seems good enough, and safe, so I'll proceed with that. And I'm much more enlightened than a few days ago. > -Paul -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging. OpenGL. Scene Graphs. GIS. GPS.
