.. py:method:: from_points(point_a: numpy.ndarray | ansys.geometry.core.typing.RealSequence | ansys.geometry.core.math.point.Point3D, point_b: numpy.ndarray | ansys.geometry.core.typing.RealSequence | ansys.geometry.core.math.point.Point3D)
   :classmethod:


   
   Create a 3D unit vector from two distinct 3D points.


   :Parameters:

       **point_a** : :obj:`~numpy.ndarray` | :obj:`RealSequence` | :obj:`Point3D`
           :class:`Point3D <ansys.geometry.core.math.point.Point3D>`
           class representing the first point.

       **point_b** : :obj:`~numpy.ndarray` | :obj:`RealSequence` | :obj:`Point3D`
           :class:`Point3D <ansys.geometry.core.math.point.Point3D>`
           class representing the second point.



   :Returns:

       :obj:`UnitVector3D`
           3D unit vector from ``point_a`` to ``point_b``.
