I'm excited about Nomad AR but it seems very limited in file size and more of a novelty at this point, only working with small objects and scaling / positioning "by eye".
The technology seems to be there to make it more powerful and user-friendly, thinking back to an app called "String AR" I used to play with with my kids back in 2011 where all you had to do was print the pattern on a sheet of paper and point the app at it, see attached Youtube video.
If there was a way to incorporate the same tech with register marks between a 3D model and matching marks or story poles on a site, think of the possibilities for pre-vis!
