Others have told you the "better way" to do this but in case you were curious why it crashes the way you've done it, I'm pretty sure it's because you aren't using ref_ptr's. Once you set root2 then root is removed from the scene and the reference count goes to zero. This means it is deleted.
No, I use ref_ptr, here was just an example . thanks, a++ Something like:
osg::ref_ptr<osg::Group> root = new osg::Group(); osg::ref_ptr<osg::Group> root2 = new osg::Group(); ...would have made the rest work since you would then be holding your own counted reference. -Paul > > other thing > I dunno if it's normal but > http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/classosgProducer_1_1Viewer.html > > there are no getSceneData or my viewer is a osg::Producer > > > thanks a+++ > > > > > ------------------------------------------------------------------------ > > _______________________________________________ > osg-users mailing list > [email protected] > http://openscenegraph.net/mailman/listinfo/osg-users > http://www.openscenegraph.org/ _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
