u"""
Orientation stored with functionality for conversion to different representations.
The following conventions apply:
- coordinate frames are right-handed.
- a rotation angle ω is taken to be positive for a counterclockwise rotation
when viewing from the end point of the rotation axis towards the origin.
- rotations will be interpreted in the passive sense.
- Euler angle triplets are implemented using the Bunge convention,
with the angular ranges as [0, 2π],[0, π],[0, 2π].
- the rotation angle ω is limited to the interval [0, π].
- the real part of a quaternion is positive, Re(q) > 0
- P = -1 (as default).
Examples
--------
Rotate vector "a" (defined in coordinate system "A") to
coordinates "b" expressed in system "B":
- b = Q * a
- b = np.dot(Q.asMatrix(),a)

Conventions
-----------
Convention 1: Coordinate frames are right-handed.
Convention 2: A rotation angle ω is taken to be positive for a counterclockwise rotation
when viewing from the end point of the rotation axis towards the origin.
Convention 3: Rotations will be interpreted in the passive sense.
Convention 4: Euler angle triplets are implemented using the Bunge convention,
with the angular ranges as [0, 2π],[0, π],[0, 2π].
Convention 5: The rotation angle ω is limited to the interval [0, π].
Convention 6: the real part of a quaternion is positive, Re(q) > 0
Convention 7: P = -1 (as default).
Usage
-----
Vector "a" (defined in coordinate system "A") is passively rotated
resulting in new coordinates "b" when expressed in system "B".
b = Q * a
b = np.dot(Q.asMatrix(),a)
