  • Samples - The Spaces AR Mesh Manager Config is an optional component to better steer the characteristics of the generated spatial mesh as mentioned in the perception sample description. With this component, the Spatial Meshing provider can also handle a possible TrackingOriginMode.Floor related camera height offset coming from runtime side. The mesh could appear at a wrong position if this component is not used in that case.
  • Samples - The Spaces AR Plane Manager Config is an optional component to enable or disable convex hull planes.
  • The start-up procedure before launching the main application activity includes a check for the Display over other app setting of the Snapdragon Spaces Services.

Changed

  • Changed accessibility level of some classes as mentioned in the migration guide.
  • Samples - Disabled the AR Camera Manager and AR Camera Background components on all samples except camera access to avoid camera lifecycle related issues, as mentioned in the known issues section. The intention is to re-enable those in the future for portability to mobile AR platforms.

[0.13.0] - 2023-05-04

Added

  • Samples - Hand Tracking has been enabled as the default input mode, if the QCHT package is included in the project. Otherwise, the Gaze Pointer is the default input mode.
  • Optional image tracking modes can be set for better control over the underlying image tracking algorithm's calculation periods. For more information regarding this change please visit the Image Tracking section.
  • Prevent Sleep Mode project setting in the Base Runtime settings to prevent application screen timeout on all devices.
  • New OriginLocationUtility class to help get the session origin, independent of type (ARSessionOrigin or XROrigin).
  • A warning will be thrown if the background for the session camera is set incorrectly when enabling Passthrough.
  • Samples - The Unity build version is now included in the info panel in the main menu.

Changed

  • Samples - Changed appearance of all the samples.
  • Samples - Updated the QCHT interactions package to version 4.0.0-pre.11.

  • Hit Testing and Plane Detection lifecycle improvements and changes:
    • Removed the distance limitation that was set internally for AR Raycasts.
    • Plane extents' calculation has been changed and can break backwards compatibility.
  • The validation rule that enforced unsafe code to be enabled was removed from the plugin and moved to the CameraFrameAccessSampleController.cs, because it is only needed in the samples.

Fixed

  • Samples - Fixed an issue with calculation of the gaze interactor position.

  • The Export Headless option in the Base Runtime feature options correctly removes intents of the SpacesLauncher activity in the final manifest.
  • The underlying Hit Testing, Plane Detection and Spatial Meshing provider stops correctly if it's not needed anymore. In older runtimes, this behavior could break expected application functionality, as the provider can't be started within 20–40 seconds. Therefore, this fix can break backwards compatibility.
  • Camera Frame Access lifecycle improvements to prevent the feature from initializing incorrectly.
[0.12.1] - 2023-04-03

Added
