Classes

Google.XR.ARCoreExtensions.ARAnchorManagerExtensions

Extensions to AR Foundation's ARAnchorManager class.

Google.XR.ARCoreExtensions.ARCloudAnchor

The ARCloudAnchor is an ARCore Extensions object that provides a similar service to AR Foundation's ARAnchor as an anchor for game objects in your scene.

Google.XR.ARCoreExtensions.ARCloudReferencePoint

Deprecated version of ARCloudAnchor.

Google.XR.ARCoreExtensions.ARCoreExtensions

ARCore Extensions, this script allows an app to specify and provide access to AR Foundation object instances that should be used by ARCore Extensions.

Google.XR.ARCoreExtensions.ARCoreExtensionsConfig

Holds settings that are used to configure the ARCore Extensions.

Google.XR.ARCoreExtensions.VersionInfo

Provides access to information about the current ARCore Extensions package runtime.

Google.XR.ARCoreExtensions.XRCameraConfigurationExtensions

Extensions to AR Subsystem's XRCameraConfiguration struct.

Enumerations

CameraConfigDepthSensorUsage

 CameraConfigDepthSensorUsage

Type of depth sensor usage for a camera config.

Properties
DoNotUse

Indicates that ARCore will not attempt to use a depth sensor, even if it is present.

Most commonly used to filter camera configurations when the app requires exclusive access to the depth sensor outside of ARCore, for example to support 3D mesh reconstruction. Available on all ARCore supported devices.

RequireAndUse

Indicates that a depth sensor must be present on the device, and the depth sensor will be used by ARCore.

Not supported on all devices.

CloudAnchorMode

 CloudAnchorMode

Defines possible modes for ARCore Cloud Anchors.

Properties
Disabled

Cloud Anchors are disabled.

This is the default value.

Enabled

Cloud Anchors are enabled, HostCloudAnchor() and ResolveCloudAnchorId() functions are available.

The app is expected to have the INTERNET permission (Android only).

CloudAnchorState

 CloudAnchorState

Describes the current state of a ARCloudAnchor.

Properties
ErrorHostingDatasetProcessingFailed

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.

ErrorHostingServiceUnavailable

The ARCore Cloud Anchor service 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 Cloud Anchor service.

ErrorInternal

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.

ErrorNotAuthorized

The app cannot communicate with the ARCore Cloud because of an invalid or unauthorized API key in the manifest, or because there was no API key present in the manifest.

ErrorResolvingCloudIdNotFound

Resolving failed because the ARCore Cloud Anchor service could not find the provided Cloud Anchor Id.

ErrorResolvingPackageTooNew

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.

ErrorResolvingPackageTooOld

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.

ErrorResourceExhausted

The application has exhausted the request quota alloted to the given API key.

The developer should request additional quota for the ARCore Cloud for their API key from the Google Developers Console.

None

The Cloud Anchor is not ready to use.

Success

A hosting or resolving task for this Cloud Anchor has completed successfully.

TaskInProgress

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.

CloudReferenceState

 CloudReferenceState

Deprecated version of CloudAnchorState.

Deprecated. Please use CloudAnchorState instead.

Properties
ErrorHostingDatasetProcessingFailed

Hosting failed because the server could not successfully process the dataset for the given Reference Point.

The developer should try again after the devices has gathered more data from the environment.

ErrorHostingServiceUnavailable

The ARCore Cloud Anchor service 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 Cloud Anchor service.

ErrorInternal

A hosting or resolving task for this Reference Point has completed with an internal error.

The app should not attempt to recover from this error.

ErrorNotAuthorized

The app cannot communicate with the ARCore Cloud because of an invalid or unauthorized API key in the manifest, or because there was no API key present in the manifest.

ErrorResolvingCloudIdNotFound

Resolving failed because the ARCore Cloud Anchor service could not find the provided Cloud Anchor Id.

ErrorResolvingPackageTooNew

The Reference Point 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.

ErrorResolvingPackageTooOld

The Reference Point 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.

ErrorResourceExhausted

The application has exhausted the request quota alloted to the given API key.

The developer should request additional quota for the ARCore Cloud for their API key from the Google Developers Console.

None

The cloud reference point is not ready to use.

Success

A hosting or resolving task for this Reference Point has completed successfully.

TaskInProgress

A hosting or resolving task is in progress for this Reference Point.

Once the task completes in the background, the Reference Point will get a new state after the next update.

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. For more details, see Share AR experiences with Cloud Anchors.

Properties
Good

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.

Insufficient

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.

Sufficient

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.
