some quite some time i've been writing a set of tools to help investigate the state of a scene graph and make slight changes to the scene graph during the run-time without the need to re-compile and restart the application. I can this tool set the SceneGraphInspector or SGI for short.
Here a screenshot of SGI in action (showing the detail about a stateSet):
It can be used with osgEarth scenes as well. A plugin to handle the osgEarth classes is included.
It's available at https://github.com/aroth-fastprotect/sgi for download. You need a recent version of OSG and osgEarth (some older versions might work out-of-the-box as well, but i haven't managed to get it working with all versions).
I hope others find this tool useful as well and i would like to get feedback to improve SGI further.
