Enumerations
CameraConfigDepthSensorUsage
CameraConfigDepthSensorUsage
Type of hardware depth sensor usage for a camera config, such as a time-of-flight (ToF) sensor.
Indicates that ARCore will not attempt to use a hardware depth sensor, such as a time-of-flight sensor (or ToF sensor), even if it is present.
Most commonly used to filter camera configurations when the app requires exclusive access to the hardware depth sensor outside of ARCore, for example to support 3D mesh reconstruction. Available on all ARCore supported devices .

CloudAnchorMode
CloudAnchorMode
Describes the desired behavior of the ARCore Cloud Anchor API.
The Cloud Anchors API uses feature maps to persist an anchor throughout sessions and across devices. See the Cloud Anchors developer guide for more information.
The default value is CloudAnchorMode.Disabled
. Use ARCoreExtensionsConfig.CloudAnchorMode
to set the desired mode.
The Cloud Anchor API is disabled.
Calling ARAnchorManagerExtensions.HostCloudAnchorAsync(this ARAnchorManager, ARAnchor,
int)
and ARAnchorManagerExtensions.ResolveCloudAnchorAsync(this ARAnchorManager,
string)
will cause the promise to fail immediately.
This is the default value.
The Cloud Anchor API is enabled.
ARAnchorManagerExtensions.HostCloudAnchorAsync(this ARAnchorManager, ARAnchor,
int)
and ARAnchorManagerExtensions.ResolveCloudAnchorAsync(this ARAnchorManager,
string)
can be used to host and resolve Cloud Anchors.
Using this mode requires your app to do the following:
- On Android: Include the
ACCESS_INTERNETpermission to the app's AndroidManifest, - Configure authorization .
Use ARCoreExtensionsConfig.CloudAnchorMode
to set this mode.
CloudAnchorState
CloudAnchorState
Result status of a Cloud Anchor hosting or resolving operation.
Hosting failed because the server could not successfully process the dataset for the given Cloud Anchor.
The developer should try again after the devices has gathered more data from the environment.
The ARCore API was unreachable.
This can happen because of a number of reasons. The device may be in airplane mode or does not have a working internet connection. The request sent to the server could have timed out with no response, there could be a bad network connection, DNS unavailability, firewall issues, or anything that could affect the device's ability to connect to the ARCore API.
A hosting or resolving task for this Cloud Anchor has completed with an internal error.
The app should not attempt to recover from this error.
The app cannot communicate with the ARCore API because of an invalid authentication.
Check Project Settings > XR Plug-in Management > ARCore Extensions for a valid authentication strategy.
Resolving failed because the ARCore API could not find the provided Cloud Anchor Id.
The Cloud Anchor could not be acquired because the ARCore Extensions package used to host the Cloud Anchor was older than and incompatible with the version being used to acquire it.
The Cloud Anchor could not be resolved because the ARCore Extensions package used to host the Cloud Anchor was newer than and incompatible with the version being used to acquire it.
The application has exhausted the request quota alloted to the given API key.
The developer should request additional quota for the ARCore API for their API key from the Google Cloud Developers Console.
Not a valid value for a Cloud Anchor hosting or resolving operation.
A hosting or resolving task for this Cloud Anchor has completed successfully.
A hosting or resolving task is in progress for this Cloud Anchor.
Once the task completes in the background, the Cloud Anchor will get a new state after the next update.
Deprecated.
Not returned by async methods - replaced by PromiseState.Pending
.
EarthState
EarthState
Describes the current state of Earth localization.
When AREarthManager.EarthTrackingState
does not become UnityEngine.XR.ARSubsystems.TrackingState.Tracking
, EarthState
may contain the cause of this failure.
Earth localization is enabled, and has not encountered any problems.
Check AREarthManager.EarthTrackingState
to determine if the Geospatial API can be used.
Failed to acquire Earth.
This is returned when the current session is initializing Geospatial functionalities. This state should not be active for more than a few frames.
Earth localization has been disabled on this session.
All ARGeospatialAnchor
created during this session will have UnityEngine.XR.ARSubsystems.XRCpuImage
set to UnityEngine.XR.ARSubsystems.TrackingState.None
and should be destroyed.
Earth localization has encountered an internal error.
The app should not attempt to recover from this error. Please see application logs for additional information.
The authorization provided by the application is not valid.
- The Google Cloud project may not have enabled the ARCore API.
- When using API key authentication, this will happen if the API key in the manifest is invalid, unauthorized. It may also fail if the API key is restricted to a set of apps not including the current one.
- When using keyless authentication, this may happen when no OAuth client has been created, or when the signing key and package name combination does not match the values used in the Google Cloud project. On Android, it may also fail if Google Play Services isn't installed, is too old, or is malfunctioning for some reason (e.g. killed due to memory pressure).
The package is older than the supported version.
The application has exhausted the quota allotted to the given Google Cloud project.
The developer should request additional quota for the ARCore API for their project from the Google Cloud Console.
Failed to find a valid ARCore session.
This is returned when the session is not active or not fully initialized, see UnityEngine.XR.ARFoundation.ARSession.state
for details on the state of the session.
FeatureMapQuality
FeatureMapQuality
Indicates the quality of feature points seen by ARCore in the preceding few seconds from a given camera Pose
.
A higher quality indicates that a Cloud Anchor hosted at the current time, with the current set of recently seen feature points, is generally easier to resolve more accurately. See the Cloud Anchors developer guide for more information.
The quality of feature points seen from the pose in the preceding few seconds is likely sufficient for ARCore to successfully resolve a Cloud Anchor with a high degree of accuracy.
The quality of feature points seen from the pose in the preceding few seconds is low.
This state indicates that ARCore will likely have more difficulty resolving the Cloud Anchor. Encourage the user to move the device, so that the desired position of the Cloud Anchor to be hosted is seen from different angles.
The quality of feature points seen from the pose in the preceding few seconds is likely sufficient for ARCore to successfully resolve a Cloud Anchor, although the accuracy of the resolved pose will likely be reduced.
Encourage the user to move the device, so that the desired position of the Cloud Anchor to be hosted is seen from different angles.
FeatureSupported
FeatureSupported
Indicates whether a feature or capability is supported on the device.
The feature or capability is supported.
Support is unknown.
This could be because support is still being determined.
The feature or capability is not supported.
GeospatialMode
GeospatialMode
Describes the desired behavior of the ARCore Geospatial API.
The Geospatial API uses a combination of Google's Visual Positioning System (VPS) and GPS to determine the geospatial pose.
The Geospatial API is able to provide the best user experience when it is able to generate high accuracy poses. However, the Geospatial API can be used anywhere, as long as the device is able to determine its location, even if the available location information has low accuracy.
- In areas with VPS coverage, the Geospatial API is able to generate high accuracy poses. This can work even where GPS accuracy is low, such as dense urban environments. Under typical conditions, VPS can be expected to provide positional accuracy typically better than 5 meters and often around 1 meter, and a rotational accuracy of better than 5 degrees. Use
AREarthManager.CheckVpsAvailabilityAsync(double, double)to determine if a given location has VPS coverage. - In outdoor environments with few or no overhead obstructions, GPS may be sufficient to generate high accuracy poses. GPS accuracy may be low in dense urban environments and indoors.
A small number of ARCore supported devices do not support the Geospatial API. Use AREarthManager.IsGeospatialModeSupported(GeospatialMode)
to determine if the current device is supported. Affected devices are also indicated on the ARCore supported devices page
.
When the Geospatial API and the Depth API are enabled, output images from the Depth API will include terrain and building geometry when in a location with VPS coverage. See the Geospatial Depth Developer Guide for more information.
The default value is GeospatialMode.Disabled
. Use ARCoreExtensionsConfig.GeospatialMode
to set the desired mode.
The Geospatial API is disabled.
When a configuration with Disabled
becomes active on the AR session, current anchors created from ARAnchorManagerExtensions.AddAnchor(
UnityEngine.XR.ARFoundation.ARAnchorManager, double, double, double,
UnityEngine.Quaternion)
will stop updating and have their UnityEngine.XR.ARSubsystems.TrackingState
set to UnityEngine.XR.ARSubsystems.TrackingState.None
.
ARCore Extensions will not request location permissions.
The Geospatial API is enabled, and AREarthManager
can be used.
Using this mode requires your app do the following:
- On Android, be granted the Android
ACCESS_FINE_LOCATIONpermission . ARCore Extensions will request this permission when Geospatial is enabled in ARCore Extensions Project Settings > Optional Features. - On Android, have enabled Unity's Internet Access permission in Android Player Settings .
- On iOS, have at least
CLAuthorizationStatus authorizedWhenInUseandCLAccuracyAuthorization fullAccuracyin iOS's Location Services permissions.
Location is tracked only while ARSession
is enabled. While it is disabled, AREarthManager.EarthTrackingState
will be UnityEngine.XR.ARSubsystems.TrackingState.None
.
For more information, see documentation on the Geospatial API on Google Developers .
This mode is not compatible with the CameraFacingDirection.User
(selfie) camera; use the CameraFacingDirection.World
camera instead.
Not all devices support this mode, use AREarthManager.IsGeospatialModeSupported(GeospatialMode)
to check if the current device and selected camera support enabling this mode.
When the Geospatial API and the Depth API are enabled, output images from the Depth API will include terrain and building geometry when in a location with VPS coverage. See the Geospatial Depth Developer Guide for more information.
