Hi Michael the code looks very compact / efficient
So I think when you say

moi.vectorMath.createTopFrame() );

That means xyz = 0 and that expression = default position.

But if I wanted it to be less efficient with the code or longhand and see where to change xyz the values by code, I guess it is:

var frame = moi.vectorMath.createTopFrame();
frame.origin.x = 0;
frame.origin.y = 0;
factory.setInput( 0, frame );.

[where’s the z though ? is it in the empty () after Top Frame or is it in the set input ( 0, frame );

or can we have -

var frame = moi.vectorMath.createTopFrame();
frame.origin.x = 0;
frame.origin.y = 0;
frame.origin.z = 0;
factory.setInput( 0, frame );.
