def pose_to_quat(pose: Sequence[Union[float, int]]) -> Sequence[float]

Description

The operator pose_to_quatpose_to_quatPoseToQuatPoseToQuatpose_to_quat converts the rotation of the input 3D pose PosePosePoseposepose into its corresponding quaternion QuaternionQuaternionQuaternionquaternionquaternion. Note that the translation of PosePosePoseposepose is ignored. Multiple poses can be passed in PosePosePoseposepose, in which case a quaternion is returned for each of them.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
