Questions tagged [augmented-reality]

For question about real-time, 3D and interactive mix of real and virtual components. Only use this tag when a specific platform tag doesn't exist or the question is sufficiently cross-platform.

Augmented reality (AR) is a term for a live direct or an indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input, such as sound or graphics. It is related to a more general concept called mediated reality, in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result, the technology functions by enhancing one’s current perception of reality. By contrast, virtual reality replaces the real world with a simulated one.

Is it possible to track objects in ARKit like in Vuforia?

I couldn't find any information if Apple's ARKit supports 3D object tracking (or even image tracking) like Vuforia does. I don't want to place a 3D model just anywhere in the world. Instead I want to detect a specific 3D object and place AR objects…
