The synergy between ARKit and the iPhone camera is what makes tools like Wonder Ruler possible. Its AR measure feature captures the AR scene and freezes it as a photograph with embedded measurement data.
Integration points:
- AVCaptureSession for photo capture
- ARSCNView for AR scene rendering
- CIImage for compositing measurements onto the camera feed
- Core Graphics for annotation rendering
This seamless integration is what makes AR measure feel magical — measurements that stay with your photos forever.
