Maybe the cessna file uses some modern feature that isn't available with the legacy drivers. The cessna model is about as vanilla OpenGL 1.x as you can get. It's been part of the OSG data for over a decade without problems. For an OSG app to lock the whole machine up suggests a driver issue as the OSG code itself is all just straight forward C++, there aren't any clever hacks. On the OpenGL side we just pass data along to OpenGL and let the driver do what it needs to do. The drivers themselves are low level with direct control of hardware and collaborate with the OS at low level so has lots of potential for bugs to cause major failures.

Re: [osg-users] [build] Trouble Building Stable 3.0.1 And Conflicting Newer Libraries
Hi Michael, Just back from my holiday and catching up with things. Looking at this thread it sounds like a driver problem that is being revealed by certain types of OpenGL usage that the OSG is producing with the models in question. There is a chance it's an obscure OSG bug that others haven't come across (you are the first to report this type of problem), but for now I think it most likely that the it's a driver issue. What hardware and drivers are you using? Have you tried on any other OS+driver+hardware combinations? Robert.

Re: [osg-users] [build] Trouble Building Stable 3.0.1 And Conflicting Newer Libraries
Ok, I've narrowed down the problem. It turns out it only occurs with some of the .osg/.osgt files from the SampleData. If I try and load the cessna.osg, cessna.osgt, cow.osg, or cow.osgt files, then my entire computer instantly freezes so badly that I can't even kill the process. But if I load the fountain.osgt file, everything works fine. It even animates the fountain's particle system just fine. I've checked and the problem exists with either the arch 3.2.1 build or when I build 3.0.1 myself. I'm using the 3.0.0 sample data. Is there an updated version? Or do I need to convert the files somehow? I'm kind of lost because everything freezes so fast that I don't even get any erros messages printed to the log. The log is completely empty, a black screen shows up, and then the entire computer freezes and I'm forced to shutdown and start all over. I've been reading through the Quick-Start guid for 3.0.0 and basically all of the features seem to work fine. It's just loading those particular scene files that causes this error. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=64498#64498 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
