Louvers with point attractors: average vector

I am using a definition from Formularch to orient louvers according to multiple points.
I am looking for a way to make more gradual transition between the orientation of the louvers, like an average of the vector direction when the louvers is at a certain distance from the attractor point.
Should I use the field component?
Thank you for any tips.
