WebMay 11, 2012 · 3 Answers. Sorted by: 5. In order to invert a rotation by unit quaternion q followed by a translation v, you apply a rotation by unit quaternion q' followed by a translation v' where: q' = ~q (conjugate of q, ie. inverse of rotation q) v' = -~q v q (transform of -v by the inverse of rotation q) If you only do translations and rotations, it is ...
