py3dframe.Frame.quaternion

property Frame.quaternion: ndarray

The quaternion representation of the rotation between the parent frame and this frame in the convention of the frame.

The quaternion is in the scalar first convention [w, x, y, z].

Note

This property is settable.

Parameters:

quaternion (numpy.ndarray) – The quaternion between the parent frame and this frame in the convention of the frame as an array-like with 4 elements. The quaternion is in the scalar first convention [w, x, y, z].

Returns:

The quaternion between the parent frame and this frame in the convention of the frame with shape (4,). The quaternion is in the scalar first convention [w, x, y, z].

Return type:

numpy.ndarray
