Re: [osg-users] Quad Buffer Stereo in osgViewer::CompositeViewer
Hi, Just a note to say this is now completely resolved. It was my fault, the stereo failed in my application because I was setting up the display settings of the 3D view after adding it to the composite viewer. Anyone who is trying to get something similar to work please beware: The order of operations in setting up composite views matters A LOT. The issues with enabling the active stereo on my Stereo Monitor were resolved by setting the Select when the display is in 3D mode: option to Always in the Nvidia control panel. Thanks again for the help! ...

[osg-users] Quad Buffer Stereo in osgViewer::CompositeViewer
Hi, I've been struggling with this for over a week now, its really blocking progress on my project. Basically, I can't seem to get quad buffer stereo working in any sort of compositeviewer. For what its worth, both the osgcompositeviewer example and my own application show the same error : Warning: detected OpenGL error 'invalid operation' at after RenderBin::draw(..) ..and refuse to show anything other than a mono view. I get the same issue on both my builds: a MinGW Windows 7 build and a gcc build on Arch Linux. My OpenSceneGraph is built from source in both cases using the latest revision in trunk (14459) Finally all other stereo modes seem to work in all cases, on both builds. I've been trying to track the problem down using a debugger without any luck. I'm going to try and debug the GL calls next, but was wondering if anyone else had experienced anything similar. ... Thank you!

Re: [osg-users] Quad Buffer Stereo in osgViewer::CompositeViewer
Hi Robert, Many thanks for the quick response. I'm currently testing on an Nvidia Quadro 600 on windows with drivers I've just updated. I've enabled stereo on the control panel and I have seen other applications (and the demo) working fine. The linux build is on a virtual machine.. so I would not expect stereo to actually 'work' with that.. but I'd at least expect to see the usual flickery ghosting of frame sequential output. Just an added additional note: the osgviewer application 'looks' like its rendering frame sequential - but does't seem to trigger my nView stereo monitor. Again, osgcompositeviewer shows no signs of quad buffer output at all. Hope this helps. Guy ... Thank you!

Re: [osg-users] Quad Buffer Stereo in osgViewer::CompositeViewer
Hi, OK, I've made some progress. osgcompositeviewer seems to be producing frame sequential output as expected when I use the -2 flag to full screen it. The problem with the default settings was that the WSI graphics context wasn't getting initialised with stereo enabled. Still not playing nice will nView.. but its definitely progress. ... Thank you!
