Augmented reality (AR) is a technology that overlays a computer-generated image on a user's view of the real world, providing a composite view.
The Unreal Engine AR framework provides a rich, unified framework for building augmented reality apps with the Unreal Engine for both iOS and Android handheld platforms. The unified framework provides a single path of development for both platforms, allowing developers to build augmented reality apps for both platforms using a single code path. The Handheld AR Blueprint template provides a complete example project demonstrating the augmented reality functionality available in the Unreal Engine.
Augmented reality provides user experiences that add 2D or 3D elements to a live view from a device's camera in a way that makes those elements appear to inhabit the real world.
