|A "headless" mode is a long-standing feature request, especially requested by developers and contributors who are hoping to do better/automated regression testing (valgrind, gdb, gprof). At the moment, it isn't directly possible - not without modifying the C++ source code and and rebuilding FG from source. You would basically have to change our OSG init code such that the window is not visible, note that you would still require OSG and X11 obviously, the window just wouldn't be shown - so that FG could be run from a console/shell | |||

|the main camera is created in CameraGroup::buildCamera and a pbuffer is allocated when you set osg::GraphicContext::Traits.pbuffer to true. These traits are available in buildCamera because we set width and height there. For debugging purpose, you can add a line like | |||
<syntaxhighlight lang="cpp">window->gc->getTraits()->pbuffer=true; | |||
</syntaxhighlight>at the end of this function. | |||
