2D to 3D design differences

      After reading this article about designing in a 3D space as compared to 2D 2D to 3D . This told me that the techniques used when making user interfaces is entirely different. Its weird that I figured this out now when 2d and 3d have a different experience already so the design should also be different, but relatively relatable. There is a body lock tag along design where the interface follows u. And their is world locked view where the ui is locked at a position and the user can walk passed it like a billboard on a highway. The design industry is going through a major change and it is heading torwards 3d and more a user immersion. I need to learn the wave now or get left behind.
