Google constantly provides links to rave reviews on the use of the vuforia framework and start-up manuals. But it is a commercial product, with limited access for developers. I do not like it. I wonder how it works, what algorithms are used to determine the angle at which they look at the object / image. Is there somewhere an opportunity to read about it, preferably in an accessible style. I would at least understand the principle before burrowing in the wilds.
Thank!
