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.
