SA E - Sum Eulerian angles

(10/21/11)

PURPOSE

To combine Eulerian angles from two successive 3D rotations. The combined values, saved in registers, can then be applied to the original volume. Additive interpolation errors are thus avoided.   Example.

SEE ALSO

SA 3 [Sum Alignment in 3D]

USAGE

.OPERATION: SA E [phi],[theta],[psi]
[The three output registers receive the combined rotation angles in order: phi, theta, psi.]

.FIRST TRANSFORMATION ROTATION ANGLES (PHI, THETA, PSI): 56.0 34.4 67.9
[The Euler angles for the first rotation.]

.SECOND TRANSFORMATION ROTATION ANGLES (PHI, THETA, PSI): 56.0 34.4 67.9
[The Euler angles for the second rotation.]

NOTES

  1. The parameters agree with commands 'RT 3D' and 'OR 3Q'.
