from_euler

classmethod Quaternion.from_euler(euler: Union[ndarray, tuple, list], direction: str = 'lab2crystal', degrees: bool = False, **kwargs) → Quaternion

Initialize from Euler angle set(s) [Rowenhorst et al., 2015].

Parameters:

euler

Euler angles in radians (degrees=False) or in degrees (degrees=True) in the Bunge convention.

direction

Direction of the transformation, either "lab2crystal" (default) or the inverse, "crystal2lab". The former is the Bunge convention. Passing "MTEX" equals the latter.

degrees

If True, the given angles are assumed to be in degrees. Default is False.

Returns:

q

Unit quaternions.
