In many of the XML files it had been noted that when the documentation refers to a return value, both "Return" and "Returns" are used. This has now been fixed to only say "Returns". Fixes #28867

<description>
|
|
A unit quaternion used for representing 3D rotations.
|
|
It is similar to [Basis], which implements matrix representation of rotations, and can be parametrized using both an axis-angle pair or Euler angles. But due to its compactness and the way it is stored in memory, certain operations (obtaining axis-angle and performing SLERP, in particular) are more efficient and robust against floating point errors.
|
|
Quaternions need to be (re)normalized.
