This function extracts the 3D rotation from an arbitrary 3x3 matrix by refining the input quaternion. It is based on the paper "A robust method to extract the rotational part of deformations" by Müller, Matthias, Jan Bender, Nuttapong Chentanez, and Miles Macklin.

Unity Plug-in
The MuJoCo Unity plug-in allows the Unity Editor and runtime to use the MuJoCo physics engine. Users can import MJCF files and edit the models in the Editor. The plug-in relies on Unity for most aspects -- assets, game logic, simulation time -- but uses MuJoCo to determine how objects move, giving the designer access to MuJoCo's full API. See documentation and installation instructions here.
