XR Origin

The XR Origin represents the center of worldspace in an XR scene.

XR Origin

The purpose of the XR Origin is to transform objects and trackable features to their final position, orientation, and scale in the Unity scene. It specifies an Origin, a Camera Floor Offset Object, and a Camera.

Setting up the XR Origin

The XROrigin class is a shared dependency between two packages: AR Foundation (com.unity.xr.arfoundation) and XR Interaction Toolkit (com.unity.xr.interaction.toolkit). AR Foundation and XR Interaction Toolkit are independent packages, but can also be used together to build XR applications. Each package provides different XR Origin configuration options based on the types of hardware each package supports.

How to Setup for mobile AR

To create a pre-configured XROrigin for mobile AR:

Right-click in the Hierarchy window Select XR Origin (Mobile AR)

Note

Components in the XR Interaction Toolkit (XRI) are Action-based by default, and make use of the InputSystem. See the XRI Samples for example Input Actions you can use to map inputs from your controllers. If your project depends on the Legacy Input System, a legacy Device-based XR Origin is available by right-clicking in the Hierarchy window and selecting XR > Device-based > XR Origin (Device-based). See Action-based vs Device-based behaviors in the XR Interaction Toolkit manual for more information.

How to setup for all-purpose AR
