Tutorials ========= The legacy OpenSceneGraph tutorial sources were removed with the renderer replacement. Maintained visualization coverage now lives in the DART GUI implementation behind ``dart::gui`` and the restored GUI examples. From a source checkout, launch the standalone editor with ``pixi run dartsim``, or run restored example names such as ``pixi run ex atlas_simbicon``, ``pixi run ex tinkertoy``, ``pixi run ex mimic_pendulums``, and ``pixi run ex rigid_chain``.
