1.3.0

Features

• Added the MagicLeapInputSimulator prefab to provide Magic Leap input simulation (e.g. Controller) when playing in the Unity Editor.
  • To use the Magic Leap input simulator, either enable the settings option to automatically add it in Editor play mode, in Edit > Project Settings > MRTK3 > Magic Leap Settings,
    or manually place the prefab in the scene. The prefab is located in /Runtime/Common/Simulation/Prefabs/.
• Updated the StereoConvergenceDetector to use the new MagicLeapEyeTrackerFeature when using OpenXR and Magic Leap Unity SDK 2.4.0 or greater.

Bugfixes

• Fixed some minor issues in the provided samples.

1.2.0

Features

• Provide compatibility with the MRTK3 version 4.0.0 release.
  • Package functionality and options will continue to work with either MRTK3 version 3.0.0+ or version 4.0.0+ releases.
  • The runtime rig configuration option will work with either the legacy (version 3.0.0) MRTK rig or the new (version 4.0.0) MRTK rig.

Bugfixes

• Fixed an issue with detecting when the package systems are running on a Magic Leap 2 platform for secondary users, now enabling certain package functionality in this case where it was previously disabled.

1.1.0

Features

• Added an option to the Runtime Rig Configuration for OpenXR to override the XROrigin's requested tracking origin mode. The current recommended tracking origin mode for the ML2 is Device mode.
• Updated the OpenXR rig variant to request Device tracking mode.
• Made an improvement to the responsiveness of the hand and controller multimodal behavior, MagicLeapControllerHandProximityDisabler, for when the controller tracking state changes and when detecting a hand is holding the controller.
• Exposed the time threshold property of the MagicLeapControllerHandProximityDisabler component for having a consistent target before a hand switch is made.

Misc.

• Updated LICENSE and NOTICE

1.0.0

Features

• Incorporated better pinch detection and then retention when hand keypoints become occluded.
• Added a StereoConvergenceDetector utility prefab to assist in utilizing Magic Leap's camera focus distance feature, which provides better capture alignment along with reduction/removal of "judder" on device in some scenarios. Please see the Stereo Convergence Detector Examples for a demonstration of the feature.
• The Spatial Awareness Examples sample was updated to work when using the OpenXR provider.

Bugfixes

• Fixed an issue where the Setting for XR Provider choice dropdown in Edit > Project Settings > MRTK3 > Magic Leap Settings was potentially getting reset when re-visiting the page. This didn't affect any options, just may have been undesirable.

1.0.0-pre.7.1

Bugfixes

• Fixed an issue where the Magic Leap MRTK3 settings and systems were unintentionally running on platforms other than ML2 when using the OpenXR XR Provider.

Known Issues / Limitations

• The provided Spatial Awareness Examples sample, demonstrating mesh reconstruction, currently only works with the Magic Leap XR Provider. OpenXR support will be added to the sample in a later release.
• Other MagicLeap 2 apis that overlap with MRTK3 are not yet configured or hooked up.

1.0.0-pre.7

Features

• Initial support for MRTK3 on MagicLeap 2
• Support for Hand Tracking and Controller
• Support for Eye Tracking (Gaze).
• Added the Runtime MRTK XR Rig Configuration to make the default rig compatible with ML 2 input at runtime.
  • Provides an option that no longer requires modification of the scene by having had to swap in the ML rig variant.
  • Available in (Edit > Project Settings > MRTK3 > Magic Leap Settings).
• Updated compatibility to Magic Leap Unity SDK 1.6 (or later).
• Added the Runtime Permission Configuration to make permission management easier on the ML2 platform.
  • Provides an option to request or start certain permissions from settings, without needing to modify any scene.
  • Also provides for instantiating a prefab at runtime to receive permission (granted, denied) callbacks for custom handling.
  • Available in (Edit > Project Settings > MRTK3 > Magic Leap Settings).
• Updated compatibility to Magic Leap Unity SDK 1.8 (or later).
• Added two samples:
  • Eye Tracking Example - showcasing eye tracking on the ML2 platform. For best results, run the Custom Fit application to calibrate eye tracking.
  • Spatial Awareness Example - showcasing scene reconstruction/meshing of your environment with several visual options.
  • Be sure to use the Runtime Permission Configuration to request eye tracking and spatial mapping permissions for the samples to work.
• Added a General Settings area to the Edit > Project Settings > MRTK3 > Magic Leap Settings project settings.
  • Provides an option to Observe OS Setting for Enabling Hand Navigation to enable/disable Hand interactions within MRTK3 based on the OS setting. This setting defaults to off so hand interactions are available for MRTK3 by default.
• Switched package dependencies to the latest org.mixedrealitytoolkit packages from the new Mixed Reality Toolkit Org repo, (https://github.com/MixedRealityToolkit/MixedRealityToolkit-Unity), where future updates to MRTK3 will come. To use this version of the com.magicleap.mrtk3 package, be sure to update your project's MRTK3 packages to latest.
• Switched the hand ray back to the stock MRTK hand ray.
• Added an MRTK3 Keyword Recognition Subsystem for the ML2 platform.
  • Added a Keyword Recognition Subsystem sample to showcase the feature, combined with voice permission and settings enabled status to visualize what is required to enable the feature.
• Added a "Keep Rendered Alpha" setting to provide better photo & video capture capabilities, along with better segmented dimmer support. See the setting in Edit > Project Settings > MRTK3 > Magic Leap Settings > General Settings.
• The MRTK XR Rig - MagicLeap prefab has been updated to allow for a new possible minimum near clipping plane of 25cm, as apposed to the previous 37cm, when using Unity SDK 1.13 or greater and supporting OS.
• Added OpenXR support when using the com.unity.xr.openxr package (version 1.9.1 or later), and choosing the OpenXR plugin under Edit > Project Settings > XR Plug-in Management. New profiles, prefabs and settings have been provided to support running with OpenXR. Please see the OpenXR XR Provider Setup section in the README for details on configuring the project to run with the OpenXR Provider.
• Added an option to choose the hand ray algorithm between stock MRTK and an alternative Magic Leap algorithm. See the setting options in Edit > Project Settings > MRTK3 > Magic Leap Settings > General Settings.
• Added an option to choose the hand and controller multimodal behavior when using both hands and the ML controller at the same time. For instance, if the hand holding the controller should be fully disabled, or just the hand's far ray disabled. See the setting options in Edit > Project Settings > MRTK3 > Magic Leap Settings > General Settings.
• Added a Global and Segmented Dimmer sample to demonstrate Magic Leap's dimmer capabilities.

Bugfixes

• Fixed the issue with the MagicLeapAuxiliaryHandDevice not cleaning up after exiting Play Mode in Editor.
• Fixed an issue with the Runtime Rig Configuration possibly adding XR Controllers that already exist in the rig, causing issues.
  The name of a controller to be added must now not match any pre-existing rig controller in order to be added.
• Fixed an issue with near interactions and the MagicLeap Controller when the controller was added dynamically to the rig at runtime (via Runtime Rig Config).
• Fixed the auxiliary devices causing an error when playing in Editor when the ML Application Simulator was not active.
• Fixed a compile issue with an API change in HandsSubsystem within the core MRTK package.
• Fixed an issue with the hand mesh not scaling well, and causing undesirable finger pose matching, during certain hand poses on the ML 2 platform.

Known Issues / Limitations

• The provided Spatial Awareness Examples sample, demonstrating mesh reconstruction, currently only works with the Magic Leap XR Provider. OpenXR support will be added to the sample in a later release.
• Other MagicLeap 2 apis that overlap with MRTK3 are not yet configured or hooked up.
