Camera

On Android XR devices, AR Foundation's Camera subsystem controls passthrough.

This page supplements the AR Foundation Camera manual. The following sections only contain information about APIs where Google's Android XR runtime exhibits platform-specific behavior.

Tip

When developing an AR app, refer to both the AR Foundation documentation as well as the required packages for each platform you support.

Passthrough

The passthrough camera captures real-time images of the external environment to provide the user with a view of their surroundings while wearing a headset. You can use passthrough to implement immersive mixed-reality experiences, by layering virtual content on top of passthrough images of the surrounding environment.

Enable passthrough

Enable the AR Camera Manager component to enable passthrough, and disable it to disable passthrough.

AR Camera Background component

Android XR passthrough doesn't require the AR Camera Background component. If ARCameraBackground is in your scene, it has no effect on Android XR devices. If your scene only targets Android XR devices, you can safely delete the AR Camera Background component from your XR Origin's Main Camera GameObject.

Configure camera background

Android XR passthrough requires that your Camera has a transparent background. To do this, set your Background Color (Universal Render Pipeline) or Clear Flags (Built-In Render Pipeline) to Solid Color, with the Background alpha channel value set to 0.

Refer to Configure camera background for passthrough to understand how to set your camera background.

Image capture

This package does not support AR Foundation image capture.
