Changelog

All notable changes to this package will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[1.1.0-preview.6] - 2019-03-12

Fixes

  • Add dependency on Legacy Input Helpers, which were moved from Unity to a package in 2019.1.

[1.0.0-preview.22] - 2018-12-13

  • Fix package dependency

[1.0.0-preview.21] - 2018-12-13

New

  • Added Face Tracking support: ARFaceManager, ARFace, ARFaceMeshVisualizer and related scripts. See documentation for usage.

Improvements

  • Plane detection modes: Add ability to selectively enable detection for horizontal, vertical, or both types of planes. The ARPlaneManager includes a new setting, which defaults to both.
  • Add support for setting the camera focus mode. Added a new component, ARCameraOptions, which lets you set the focus mode.

Changes

  • The light estimation option, which was previously on the ARSession component, has been moved to the new ARCameraOptions component.

[1.0.0-preview.20] - 2018-11-06

Improvements

  • Support reference points reported without a corresponding TryAddReferencePoint call. This handles reference points that are added by some other means, e.g., loaded from a serialized session.

[1.0.0-preview.19] - 2018-10-10

  • Added support for XRCameraExtensions API to get the raw camera image data on the CPU. See the manual documentation for more information.

[1.0.0-preview.18] - 2018-09-13

Fixes

  • The ARPlaneMeshVisualizer did not disable its visible components (MeshRenderer and LineRenderer) when disabled. This has been fixed.

Changes

  • The ARPlaneManager, ARPointCloudManager, and ARReferencePointManager all instantiate either prefabs that you specify or GameObjects with at least an ARPlane, ARPointCloud, or ARReferencePoint, respectively, on them. The instantiated GameObject's layer was set to match the ARSessionOrigin, overwriting the layer specified in the prefab. This has been changed so that if a prefab is specified, no changes to the layer are made. If no prefab is specified, then a new GameObject is created, and its layer will match that of the ARSessionOrigin's GameObject.

New

  • Added ARPlane.normal to get the ARPlane's normal in world space.

LWRP support

Added LWRP support by allowing ARCameraBackground to use a background renderer that overrides the default functionality. This works in conjunction with some LWRPSupport files (see arfoundation-samples) that will live in your LWRP project.

[1.0.0-preview.17] - 2018-08-02

Fixes

  • Add FormerlySerializedAs attribute to serialized field changes to ARCameraBackground.

[1.0.0-preview.16] - 2018-07-26

Change

  • Removed static constructor from ARSubsystemManager. This allows access to the manager without forcing the creation of the subsystems, making the initialization more flexible.

[1.0.0-preview.15] - 2018-07-26

Fixes

  • ARPlane.vertexChangedThreshold is no longer allowed to be negative.
  • The ARCameraBackground component did not reset the projection matrix on disable, leading to stretching or other distortion. This has been fixed.
  • The ARCameraBackground component did not properly handle an overriden material. This has been fixed (see API Changes below).
  • The ARPlaneMeshGenerators was meant to generate a triangle fan about the center of the plane. However, indices were instead generated as a fan about one of the bounary points. The visual result is similar, but can lead to long thin triangles. This has been fixed to use the plane's center point as intended.
  • Update for compatibility with 2018.3
  • If the ARPlaneMeshVisualizer has a LineRenderer on it, then it will be scaled to match the ARPlane's scale, making the visual width invariant under differing ARSessionOrigin scales.
  • When the ARPointCloudManager instantiated a point cloud prefab, it did not change its transform. If it was not identity, then feature points would appear in unexpected places. It now instantiates the point cloud prefab with identity transform.
  • The menu item "GameObject > XR > AR Default Point Cloud" created a GameObject which used a particle system whose "Scaling Mode" was set to "Local". If used as the ARPointCloudManager's point cloud prefab, this would produce odd results when the ARSessionOrigin was scaled. The correct setting is "Hierarchy", and the utility now creates a particle system with the correct setting.

API Changes

ARCameraBackground

The API for overriding the material has been refactored. Previously, a custom material could be set with the ARCameraBackground.material setter, but this might be overwritten later if the option to override was disabled.

  • Rename: overrideMaterial is now useCustomMaterial
  • New member: customMaterial
  • The following properties are now private:
    • material setter (getter is still public)
    • backgroundRenderer

Use the ARCameraBackground.material getter to get the currently active material.

[1.0.0-preview.14] - 2018-07-17

Fixes

  • Fixed a bug in the ARCameraBackground which would not render the camera texture properly if the ARSession had been destroyed and then recreated or if the ARCameraBackground had been disabled and then re-enabled.
  • ARSubsystemManager.systemState's setter was not private, allowing user code to change the system state. The setter is now private.
  • ARPlane.trackingState returned a cached value, which was incorrect if the ARSession was no longer active.

Improvements

  • Added ARSession.Reset() to destroy the current AR Session and establish a new one. This destroys all trackables, such as planes.
  • Added an ARSubsystemManager.sessionDestroyed event. The ARPlaneManager, ARPointCloudManager, and ARReferencePointManager subscribe to this event, and they remove their trackables when the ARSession is destroyed.

[1.0.0-preview.13] - 2018-07-03

  • Fixed a bug where point clouds did not stop rendering when disabled.
  • Added a getter on the ARPointCloudManager for the instantiated ARPointCloud.
  • Added UVs to the Mesh generated by the ARPlaneMeshVisualizer.
  • Refactored out plane mesh generation functionality into a new static class ARPlaneMeshGenerators.
  • Added a meshUpdated event to the ARPlaneMeshVisualizer, which lets you customize the generated Mesh.
  • Added AR Icons.

[1.0.0-preview.12] - 2018-06-14

  • Add color correction value to LightEstimationData.

[1.0.0-preview.11] - 2018-06-08

  • Improve lifecycle reporting: remove public members ARSubsystemManager.availability and ARSubsystemManager.trackingState. Combine with ARSubsystemManager.systemState and the public event ARSubsystemManager.systemStateChanged.
  • Docs improvements
  • Move ParticleSystem to the top of the ARDebugPointCloudVisualizer

[1.0.0-preview.10] - 2018-06-06

  • Update documentation: ARSession image and written description.

[1.0.0-preview.9] - 2018-06-06

  • Rename ARBackgroundRenderer to ARCameraBackground
  • Unify ARSessionState & ARSystemState enums

[1.0.0-preview.8] - 2018-05-23

  • Change dependency to ARExtension 1.0.0-preview.2

[1.0.0-preview.7] - 2018-05-23

  • Remove "timeout" from AR Session
  • Add availability and AR install support
  • Significant rework to startup lifecycle & asynchronous availability check

[1.0.0-preview.6] - 2018-04-25

Rename ARUtilities to ARFoundation

  • This package is now called ARFoundation.
  • Removed ARPlaceOnPlane, ARMakeAppearOnPlane, ARPlaneMeshVisualizer, and ARPointCloudParticleVisualizer as these were deemed sample content.
  • Removed setup wizard.
  • Renamed ARRig to ARSessionOrigin.
  • ARSessionOrigin no longer requires its Camera to be a child of itself.
