matflow.param_classes.orientations.QuatOrder

class matflow.param_classes.orientations.QuatOrder(value, names=<not given>, *values, module=None, qualname=None, type=None, start=1, boundary=None)

Bases: Enum

Order in which the four quaternion components are listed.

Dream3D [1] uses vector-scalar ordering, whereas most other programs seem to use scalar-vector ordering.
