3.7.0

Compatible with Varjo Base 4.3 or newer. Add preliminary support for Unity 6.0 or newer

  • Upgrade com.unity.xr.arfoundation dependency to 5.1.3
  • Compatible with com.unity.xr.arfoundation 6.0.0

3.6.0

Compatible with Varjo Base 4.0 or newer.

Added

  • Support for Varjo Controllers
  • Support for XR-4
  • Added Varjo.XR.AutoExposureBehavior property

Changed

  • Upgrade to oldest currently supported Unity LTS version 2021.3
  • Upgrade com.unity.xr.management dependency to 4.4.0

Changed

  • Deprecated and removed support for Legacy 10-dot gaze calibration. Newer Fast 5-dot gaze calibration allows to achieve higher accuracy and precision. Requesting Legacy 10-dot gaze calibration will trigger Fast 5-dot calibration.

3.4.0

Compatible with Varjo Base 3.9 or newer.

Changed

  • Changed VarjoEyeTracking.GetGaze and VarjoEyeTracking.GetEyeMeasurements to return the really latest available data instead of the last data frame in the previous call to VarjoEyeTracking.GetGazeList or the previous Unity XR Input update.

3.3.0

Compatible with Varjo Base 3.8 or newer.

Added

  • Support for retrieving and controlling headset interpupillary distance and its adjustment (see VarjoHeadsetIPD class)
  • Support for user presence status (UnityEngine.XR.CommonUsages.userPresence)
  • Support for getting current Varjo system timestamp (VarjoTime.GetVarjoTimestamp) and support converting that timestamp to DateTime structure (VarjoTime.ConvertVarjoTimestampToDateTime)

Fixed

  • Fixed build post processing being performed when building for unsupported target platforms

Changed

  • Varjo VR-1, VR-2, VR-2 Pro and XR-1 Developer Edition are no longer supported (these devices are not supported with Varjo Base 3.8 or newer)

Removed

  • Removed YUV422 color stream conversion functions for XR-1 Developer Edition

3.2.0

Compatible with Varjo Base 3.7 or newer.

Added

  • Support for new environment cubemap mode
  • Support for blend control mask (D3D11 only)
  • Added new metadata to environment cubemap stream
  • Eye openness data to VarjoEyeTracking.EyeMeasurements structure
  • Added support for cancelling gaze calibration with VarjoEyeTracking.CancelGazeCalibration function.
  • Added new VarjoEyeTracking.HeadsetAlignmentGuidanceMode option to control whether gaze calibration user interface waits for input from user (headset button press) before starting calibration sequence.
  • Added a new camera property to control the new eye reprojection feature.

Changed

  • Eye open amount data in XR.Eyes now uses actual eye openness tracking results instead of gaze availability

3.1.1

Added

  • Device layouts for all supported SteamVR tracker roles

Fixed

  • Fixed memory layout of VarjoEyeTracking.EyeMeasurements structure

3.1.0

Compatible with Varjo Base 3.6 or newer.

Added

  • Support for up to 14 SteamVR trackers with button inputs
  • Proper support for Valve Index controllers
  • Device layouts for all supported input devices
  • DirectX 12 support (requires Unity 2021.2 or newer)
  • Function for controlling global chroma keying
  • Support for triggering "One dot" gaze tracking calibration

Changed

  • Input subsystem now ensures there is only one SteamVR controller device with a given role (left hand, right foot, keyboard etc.) and reports other devices with the same role as generic tracker devices without button inputs
  • Tracked devices have more descriptive names now

Fixed

  • Fixed Session subsystem reporting wrong installed status
  • Fixed VarjoCameraSubsystem.MetadataStream not working with IL2CPP

3.0.0

Compatible with Varjo Base 3.5 or newer.

Added

  • Support for simple two view stereo renderering
  • AR Foundation support, including the following:
    • XRSessionSubsystem provider
    • XRCameraSubsystem provider, adding support for controlling video see-through cameras with XRCameraSubsystem.Start() and XRCameraSubsystem.Stop(), accessing the camera image CPU buffers, utilities for converting the buffers to RGB and grayscale textures and support for retrieving camera intrinsics
    • XROcclusionSubsystem provider, adding support for enabling and disabling environment depth estimation with XROcclusionSubsystem.Start() and XROcclusionSubsystem.Stop()
  • New VarjoEyeTracking.EyeMeasurements structure, which provides gaze tracker's estimates for user's pupil and iris diamaters in millimeters, their ratios and user's interpupillary distance
  • New VarjoEyeTracking.GetEyeMeasurements() function for retrieving latest eye measurements data and added overload for VarjoEyeTracking.GetGazeList() function for retrieving EyeMeasurements data together with GazeData data

Changed

  • Changed minimum supported Unity version to Unity 2020.3
  • Moved camera metadata stream to VarjoCameraSubsystem.MetadataStream, where it can be accessed after calling VarjoCameraSubsystem.EnableMetadataStream()
  • Renamed EventHeadsetStandbyStatus as EventStandbyStatus and VarjoEventManager.GetEventHeadsetStandbyStatus() as VarjoEventManager.GetEventStandbyStatus()

Removed

  • Removed deprecated VarjoEyeTracking.RequestGazeCalibration(GazeCalibrationMode calibrationMode, GazeOutputFilterMode outputFilterMode) and GazeOutputFilterMode
  • Removed the old implementation of VarjoDistortedColorStream as the stream is now available through VarjoCameraSubsystem
