Do not think I shared this, but 3D, VR, and AR are not the same thing!
3D is when you put your phone up to your face with google cardboard, it has a single-point perspective. Been around for over 100 years! Augmented Reality is a plethora of things from map games like Pokemon Go to Hololens placing zombies in your home. VR is an immersive experience, unless you can manipulate he object, view it from all angles, it is not VR! Get yourself a Vive.....
There are newer emerging concepts yet to be catergorized....
