In VR, the user typically wears a headset that tracks their movements and displays a 3D image of the virtual environment. This creates a sense of presence and allows the user to interact with the environment in a more immersive way than flat screen gaming. In XR, a 3D object is masked into your vision of the physical world around the user and the user can interact with both the real world and the game world at the same time.
Suggestion: Plugin for XR reality to allow Atoms, Characters and Objects, to appear through passthrough.
" we've had a ton of developers coming to us saying hey we want camera access and then we'll be like, okay.. um we like to understand why first " - Shen Ye, Global head of product, HTC Source: Interview HTC XR elite
From the interview, a plugin would have to be requested from HTC. Unsure if camera access is needed to display a 3D object at all, but HTC is willing to work with developers on their applications.
