+tags: [2D, 3D, depth, pinhole-camera]
+description: "Real-time camera RGB, depth, and pose visualization using rerun and Unity ARFoundation."
+thumbnail: demo.png
+thumbnail_dimensions: [480, 243]

+
+![](demo.png)
+
+This example provides example code for connecting rerun with Unity3D [ARFoundation 5.1](https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@5.1/manual/index.html) for visualizing camera RGB, depth and pose in real-time.
+Inside this codebase, we provide an Unity3D client for capturing and streaming ARKit camera data, and a Python-based gRPC server for receiving and logging the device data on rerun.
+
+Note: current version only works with iOS (ARKit)-based devices.
+
+```bash
+pip install -r examples/python/arfoundation/requirements.txt
+python examples/python/arfoundation/main.py
+```
