Re: [osg-users] Advise on SLI dual quad buffered stereo display
Hi Robert, to answer your question I want to drive 4 stereoscopic displays in CAVE-like environment with active shutter glasses (frame sync hardware will be required). I haven't set up anything yet, but I plan on buying HW in the next few weeks. :-) I had found a very old thread, Oct 7 2010, "subj:OSG seems to have a problem scaling to multiple windows on multiple graphics cards", but the landscape of HW,drivers, and OSG has changed quite a bit since then. ...

Re: [osg-users] osgAudio doesn't compile against OSG 3.4
Hi Chris, one thing I forgot; I didn't overlook your invitation to send pull requests. But I still need to find my ways in C++ (coming from Python), so I can't make any suggestions for code improvement at that point. As soon as I will be able to code something helpful, I will gladly upload it and send a pull request.

Re: [osg-users] osgAudio doesn't compile against OSG 3.4
Hi Chris, as far as I understand, osgAudio tries to instance 'osg::Geometry::BIND_PER_PRIMITIVE' in both osgaudiomultiple.cpp and osgaudio.cpp, which appears to have been replaced in recent versions of OSG. Here's the error message produced by GNU make on my Ubuntu 15.10 64 bit machine (using ccmake for configuring): Building CXX object examples/osgaudio/CMakeFiles/example_osgaudio.dir/osgaudio.cpp.o /home/mic/Dev/source/osgaudio_gitmaster1602/examples/osgaudio/osgaudio.cpp: In function ‘osg::Node* createBase(const Vec3&, float)’: /home/mic/Dev/source/osgaudio_gitmaster1602/examples/osgaudio/osgaudio.cpp:216:11: error: ‘class osg::Geometry’ has no member named ‘setVertexIndices’ geom->setVertexIndices(coordIndices); ^ /home/mic/Dev/source/osgaudio_gitmaster1602/examples/osgaudio/osgaudio.cpp:219:11: error: ‘class osg::Geometry’ has no member named ‘setColorIndices’ geom->setColorIndices(colorIndices); ^ /home/mic/Dev/source/osgaudio_gitmaster1602/examples/osgaudio/osgaudio.cpp:220:27: error: ‘BIND_PER_PRIMITIVE’ is not a member of ‘osg::Geometry’ geom->setColorBinding(osg::Geometry::BIND_PER_PRIMITIVE); ^ examples/osgaudio/CMakeFiles/example_osgaudio.dir/build.make:54: recipe for target 'examples/osgaudio/CMakeFiles/example_osgaudio.dir/osgaudio.cpp.o' failed make[2]: *** [examples/osgaudio/CMakeFiles/example_osgaudio.dir/osgaudio.cpp.o] Error 1 CMakeFiles/Makefile2:290: recipe for target 'examples/osgaudio/CMakeFiles/example_osgaudio.dir/all' failed make[1]: *** [examples/osgaudio/CMakeFiles/example_osgaudio.dir/all] Error 2 Makefile:116: recipe for target 'all' failed make: *** [all] Error 2 Best regards, Michael -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=66479#66479 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Advise on SLI dual quad buffered stereo display
Hi Ted, As a general recommendation I would suggesting starting with the simplest/cheapest setup to start with to see if that is viable and then progress on to more complex/expensive solutions if required. The progression in terms of complexity would be single card single machine, dual card single machine, single machine in two or more machines. To be clear on your requirements, you are want to render in stereo, but to how many stereo displays? And what type of stereo display? What testing have you done so far and what were the results?
