Position from two layers, plannar positioning
I found a Fusion expression that I would like to know how to implement in Ae if possible.
It requires two point that can then be used interpolate a 3rd point that is adjustable.
It would be very useful for tracking.
The Fusion expression and example can be found here;

I’m not sure how you want to implement this in AE, but it might be as simple as an expression like this:
s = effect(“Slider Control”)(“Slider”);
a = thisComp.layer(“A”).transform.position;
b = thisComp.layer(“B”).transform.position;
linear(s,0,100,a,b)Dan

Setup:
P3 layer has Slider Control renamed to “weight” and adjusted value to 0 to 1
Expressions for copy-paste:
Weight Text – Source Text:
w = Math.round(thisComp.layer("P3").effect("weight")("Slider") * 100) / 100;
"w=" + w;
Weight Text – Position (used anchor point for positioning):
thisComp.layer("P3").transform.position
P3 (3rd Point) – Position:
w = effect("weight")("Slider");
p1 = thisComp.layer("P1").transform.position;
p2 = thisComp.layer("P2").transform.position;
x = ((1 - w) * p1[0]) + (w * p2[0]);
y = ((1 - w) * p1[1]) + (w * p2[1]);
[x, y];
Beam Effect – Starting Point:
thisComp.layer("P1").transform.position
Beam Effect – End Point:
thisComp.layer("P2").transform.position

Emre Anil,
Thank you so much for taking the time to post your solution, which works perfectly :-).
This will be very useful.Kind Regards,
