The function has three vector parameters: ``N``, the vector to orient, ``I``, the incident vector, and ``Nref``, the reference vector. If the dot product of ``I`` and ``Nref`` is smaller than zero the return value is ``N``. Otherwise, ``-N`` is returned. .. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)` .. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)` .. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)` .. |static| replace:: :abbr:`static (This method doesn't need an instance to be called, so it can be called directly using the class name.)`
