I want to capture my OSG screen and dump it to a jpeg or png file. My understanding is to attach a callback to the main osgViewer camera and perform a osg::Image::readPixels(...) from within the callback. That works in the simple case. But, if I have a basic HUD that is itself a camera alongside other nodes in the scenegraph, then I never see the HUD in my osg::Image::readPixels call. That would make sense since my callback is operating on the main camera and not my child node camera....but leaves the question of how do I perform a "complete" screen capture on a graph with multiple cameras?
Is there an example I missed? _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
