AR Scale in Vuforia

Hi all,
in reference to this nice article about AR Scale, which addresses a number of critical practical issues, i have a question, do these concepts apply to Vuforia (not in the case of using ARCore/ARKit internally) ?
https://blogs.unity3d.com/2017/11/16/dealing-with-scale-in-ar/

Concepts include calculation of real dimensions, scaling, stationary objects, using camera to trick scaling, etc... ?

 

Assuming you're using the image tracking feature, the real dimensions are dependent on the size you give your image target. If you want your scene units to be meters (as is the case for arkit/arcore), you would enter the width as meters. So 30 cm would be a width of 0.3.

Things like the scaling are indeed the same as in that blog. They're not even realy AR specific.
