from_euler#
- classmethod OrientationRegion.from_euler(euler: ndarray | tuple | list, direction: str = 'lab2crystal', degrees: bool = False) Quaternion [source]#
Create unit quaternions from Euler angle sets [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 isFalse
.
- Returns:
Q
Unit quaternions.
