Added

• Added extension function XRMeshSubsystem.IsSceneMeshId(TrackableId).

Changed

• None.

Deprecated

  • Foveation feature is required for Subsampling (Vulkan). Otherwise, the application may result in rendering faulty.
  • For projects with Universal Render Pipeline (URP), select Foveated Rendering feature. Check Foveated rendering in OpenXR for more details.
  • For projects with Built-in Render Pipeline (BiRP), select Foveation (Legacy) feature for legacy support.
• Scene Meshing is promoted from experimental feature to release feature.

Deprecated

• None

Removed

  • 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.

  • 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.
