Description

The operator pose_to_dual_quatpose_to_dual_quatPoseToDualQuatPoseToDualQuatPoseToDualQuat converts the input PosePosePosePosepose into its corresponding unit dual quaternion DualQuaternionDualQuaternionDualQuaternionDualQuaterniondualQuaternion.

For a brief introduction to dual quaternions, the used notation, and the relationship between dual quaternions and screws, see the documentation of this chapter (Transformations / Dual Quaternions).

Because and represent the same rigid transformation, the sign of the resulting dual quaternion DualQuaternionDualQuaternionDualQuaternionDualQuaterniondualQuaternion is chosen such that the scalar part of the real part is .

Multiple poses can be passed in PosePosePosePosepose, in which case a unit dual quaternion is returned for each of them.
