New Codes for Quaternions
Posted: Thu Jun 25, 2009 1:16 pm
Dear colleagues,
exchanging angle information needs some additional information about the order of rotation and the usage
of fix or rotating axes. This problem can be avoided by using 4 quaternions instead of 9 elements of a rotation matrix.
These quaternions have the unit [1] and are named qw, qx, qy, qz.
Therefor I propose the new Physical Dimension QU with the text "Quaternion" and the default unit "1".
To distinguish between the 4 quaternions we can use the Directions X, Y, Z and need
a new Direction W.
