3D, 3D, 3D ( and some real 2D)

The word 3D is becoming even more undefined than VR.  We keep seeing “3D” everywhere and before clicking you can’t guess which 3D is being talked about.

Is it 3D computer graphics ?

Is it stereoscopic ?

Is it just because it’s not in 2D ?

Philippe Fuchs made me laugh last week when he said : “Hey I finally found a real 2D movie !!!”

So I guess what we all do is 3D, 3D, and 3D ! 3D because we can perceive depth, 3D because it’s computer graphics and 3D because it’s stereoscopic !
