scipp.spatial.rotation#

scipp.spatial.rotation(*, value)#

Creates a rotation-type variable from the provided quaternion coefficients.

The quaternion coefficients are provided in scalar-last order (x, y, z, w), where x, y, z and w form the quaternion w + xi + yj + zk.

Parameters

value (Union[ndarray, list]) – a numpy array or list with length 4, corresponding to the quaternion coefficients (x*i, y*j, z*k, w)
