The unified AR framework includes support for basic AR functionality like Alignment, Light Estimation, Pinning, Session State, Trace Results, and Tracking. In addition to these, you can also use the latest features available in ARKit on your iOS devices
ARKit 4.0
The engine supports ARKit 4.0, which includes the following immersive features:
- 2D Image Detection
- 3D Object Detection
- Face Tracking, including support for devices without the TrueDepth Camera
- Persistent Experiences
- Shared Experiences
- People Occlusion
- Motion Capture (2D, 3D, LiveLink)
