// the delta rotation axis, scaled by the object mass times an arbitrary scaling
// factor (to ensure the resulting torque is not "too strong" or "too weak").

// of torques needed to arrive exactly at the destination orientation. However, since
// it is not yet clear how to map the destination orientation (provided by the viewer)
