Android XR Extensions for Unity v1.0.0 Release

  • This version of the package requires minimal Unity Editor version 6000.1.0b12. You can install the official Unity 6.1 (e.g. 6000.1.0f1 or newer) from the Unity Hub.
  • Package dependencies updated in this version:
    • OpenXR Plugin (com.unity.xr.openxr) 1.14.2
    • AR Foundation (com.unity.xr.arfoundation) 6.1.0
  • Verified compatible packages:
    • Unity OpenXR Android XR (com.unity.xr.androidxr-openxr) 1.0.0-pre.2
    • Composition Layer (com.unity.xr.compositionlayers) 2.0.0

Known issues

  • Vulkan Subsampling now causes rendering issues in multiple samples, including ImageTracking, HandMesh, SceneMeshing, and XRController.
    • It's confirmed as a regression issue from OpenXR Plugin package, expect to be fixed by future releases.
    • Workaround: To disable it, under the setting menu of Android XR (Extensions) Session Management, unselect Subsampling (Vulkan).

Added

  • Marker Tracking and QR Code Tracking:
    • New OpenXR Feature XRMarkerTrackingFeature which provides marker tracking via ARTrackedImageManager. Including APIs:
      • Extension method ARTrackedImage.IsMarker() to check if the image instance is a marker.
      • Extension method ARTrackedImage.TryGetMarkerData(out XRMarkerDictionary, out int) to get marker data from a marker instance.
      • New ScriptableObject XRMarkerDatabase, a container of XRMarkerDatabaseEntry, used to manage marker references in an XRReferenceImageLibrary.
    • New OpenXR Feature XRQrCodeTrackingFeature which provides QR Code tracking via ARTrackedImageManager. Including APIs:
      • Extension method ARTrackedImage.IsQrCode() to check if the image instance is a QR Code.
      • Extension method ARTrackedImage.TryGetQrCodeData(out string) to get the QR code data from a QR Code instance.
    • New implementation of XRImageTrackingSubsystem. To use it with AR Foundation's ARTrackedImageManager, create an XRReferenceImageLibrary with a QR Code reference named QrCode and/or updates marker references from XRMarkerDatabase.
    • New sample ImageTracking which demonstrates the usage of QR Code tracking and marker tracking.
  • Added experimental features support which use OpenXR extensions XR_ANDROIDX_*. Noted:
    • Applications can then access ANDROIDX extensions at runtime but cannot be published in Google Play Store.
    • Experimental features can take several iterations towards formal releases which may include breaking changes, deprecation, and removal.
  • Body Tracking (Experimental):
    • New Experimental OpenXR Feature XRBodyTrackingFeature which provides body tracking via ARHumanBodyManager.
    • New sample BodyTracking which demonstrates the usage of body tracking.
  • System State (Experimental):
    • New Experimental OpenXR Feature XRSystemStateFeature which provides system state via TryGetSystemState(out systemState).
    • Added system state API usage to BlendMode sample.
  • Scene Meshing (Experimental):
    • New Experimental OpenXR Feature XRSceneMeshingFeature which provides scene mesh data via XRMeshSubsystem.
    • Added new sample SceneMeshing which demonstrates the usage of scene meshing API.

Changed

  • Subsampling (Vulkan) is now disabled by default in Android XR (Extensions) Session Management.
  • Face Tracking:
    • Updated XRFaceParameterIndices with new enum values for tongue blendshapes.
    • Updated XRFaceState with new property ConfidenceRegions, indexed by new enum XRFaceConfidenceRegion.

Deprecated

  • N/A

Removed

  • Removed XRTrackableFeature, XRAnchorFeature, and Trackables sample. Please use ARPlaneFeature and ARAnchorFeature from Unity OpenXR Android XR instead.
  • Removed XRDisplayRefreshRateFeature and DisplayRefreshRate sample. Please use DisplayUtilitiesFeature from Unity OpenXR Android XR instead.

Fixed

  • Fixed typo in XRHandMeshFeature which referred to depth texture permission rather than hand tracking permission.
  • Fixed bug in XRHandMeshFeature which started a subsystem in the OnSubsystemStop() callback.
