Or your overpowered iPad. But yes it's basically it. Except that you have more information by doing this since it gives you the size of the object (useful for la Joconde and Apple I for exemple). And you can compare several objects together. Two things that you don't easily have with an embedded 3d browser.
I haven't printed those yet but how do you compare several objects at once?
In the app itself, on the iOs version (not yet on Android), you can tap "Add" instead of "Augment" and it will add several objects in the same scene.
