Rotation around omega
Quaternions
Table of quaternions was generated using methods in pyimgalgos/src/Quaternion.py
Self-test for Quaternion
self-test uses a chain of conversions:
angles -> rotation matrix -> quaternion -> rotation matrix -> angles
,
where in and out angles and rotation matrix coincide.
Script cxif5315/make-quaternions.py
generates file with a list of quaternions from file with table of angles
