Because 3d in VR/AR feels really unnatural without a little bit of physical smoothing of movement. At the very least easing and collisions are necessary to make interactive components. Right now most of the game engines are total overkill for business apps but basic GUI libraries don't have the physical attributes that make for a natural, intuitive user experience. We are really lacking tools for this new experience. I don't think Qt has solved this problem but I think it demonstrates the need exists. Source: I write AR apps.
