Re: [osg-users] OSG , Qt and osgsimplifier
Hello Sajjad, Any hint ? With only this information, the only hint we can give you is to use the debugger. Running in debug, and enabling exception reporting, the debugger should break exactly where the crash occurs, and you should be able to go up the stack to see the source of the crash and see if you can fix it. Hope this helps, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] OSG , Qt and osgsimplifier
Hello Jean, Just ran the debugger. and crashes in the following line * viewer.frame(); ***' Any way to get around that ? Each frame is shown after the mesh is simplified(). In qt adapter the viewer class has two parents AdapterWidget and osg::osgViewer. Could that be the problem ?

Re: [osg-users] OSG , Qt and osgsimplifier
Hello Sajjad, Just ran the debugger. and crashes in the following line * viewer.frame(); Are you running a debug build in the debugger? Do you have the debugging symbols for OSG? That specific line is not the site of the crash, it's something that function is doing, so to get to the real source of the crash you need to have debugging symbols and walk down the stack.

Re: [osg-users] OSG , Qt and osgsimplifier
The only suggestion I can think of is to make sure you are using the single threaded threading model: setThreadingModel(osgViewer::Viewer::SingleThreaded); AFAIK, QT viewers will not work with any of OSG's multi-threaded models.
