AR Starter Assets

This sample is installed into the default location for package samples, in the Assets\Samples\XR Interaction Toolkit\[version]\AR Starter Assets folder. You can move these Assets to a different location after importing it.

The XR Interaction Toolkit package provides an example implementation for mobile AR development. This includes the a demo scene and some prefabs to get you started with your own projects.

Asset	Description
DemoAssets\	Asset folder containing assets only used for the ARDemoScene.
Editor\Scripts\	Asset folder containing Unity Editor scripts which adds Project Validation rules for the sample.
Materials\FeatheredPlaneMaterial	This material provides a visual representation used for AR plane detection in the XR Simulator and in builds.
Prefabs\AR Feathered Plane	This prefab uses the FeatheredPlaneMaterial to show where the AR plane is detected or simulated.
Prefabs\Screen Space Ray Interactor	This prefab contains the component for adding the input device to the input system that the Touchscreen Gestures actions are bound to and the XR Ray Interactor setup to work with mobile AR devices.
Prefabs\XR Origin (AR Rig)	This contains the basic configuration to use interactions with a mobile device, containing components from AR Foundation and leveraging the Screen Space Ray Interactor prefab and the AR settings on the XR Ray Interactor.
Scripts\ARContactSpawnTrigger	Component that spawns an object from the designated list at the physical contact point with an AR plane.
Scripts\ARFeatheredPlaneMeshVisualizer	Component that supports a feathering effect at the edge of a detected plane, which reduces the visual impression of a hard edge.
Scripts\ARInteractorSpawnTrigger	Component that spawns an object from the designated list at the point where the Ray Interactor hits the AR plane when the specific Spawn Object action is triggered from the Input System.
ARDemoScene	Scene that illustrates a basic AR rig setup that supports screen space touch gestures along with example interactable objects that can be spawned and UI.
