## Classes

| Name | Type | Summary |
| --- | --- | --- |
| Provider | SubsystemProvider<XRVps2AnchorSubsystem> | The provider API for XRVps2AnchorSubsystem-derived classes to implement. |
| Provider | SubsystemProvider<XRVps2AssetSubsystem> | The provider API for XRVps2AssetSubsystem-derived classes to implement. |
| Provider | SubsystemProvider<XRVps2Subsystem> | - |
| Provider | SubsystemProvider<XRDeviceMappingSubsystem> | - |
| Provider | SubsystemProvider<XRSceneSegmentationSubsystem> | The provider which will service the XRSceneSegmentationSubsystem. |
| Provider | SubsystemProvider<XRScanningSubsystem> | An abstract class to be implemented by providers of this subsystem. |
| Vps2AssetId | Vps2AssetId | Conversions between VPS asset UUID strings and TrackableIds. |
| XRDeviceMappingSubsystem | SubsystemWithProvider<XRDeviceMappingSubsystem, XRDeviceMappingSubsystemDescriptor, Provider> | - |
| XRDeviceMappingSubsystemDescriptor | SubsystemDescriptorWithProvider<XRDeviceMappingSubsystem, Provider> | - |
| XRScanningConfiguration | XRScanningConfiguration | Configuration for scanning. |
| XRScanningSubsystem | SubsystemWithProvider<XRScanningSubsystem, XRScanningSubsystemDescriptor, Provider> | Defines an interface for interacting with scanning functionality. |
| XRScanningSubsystemDescriptor | SubsystemDescriptorWithProvider<XRScanningSubsystem, Provider> | - |
| XRSceneSegmentationSubsystem | SubsystemWithProvider<XRSceneSegmentationSubsystem, XRSceneSegmentationSubsystemDescriptor, Provider>, ISubsystemWithModelMetadata | Defines an interface for interacting with semantic segmentation functionality. |
| XRSceneSegmentationSubsystemDescriptor | SubsystemDescriptorWithProvider<XRSceneSegmentationSubsystem, Provider> | Descriptor for the XRSceneSegmentationSubsystem. |
| XRVps2AnchorSubsystem | TrackingSubsystem<XRVps2Anchor, XRVps2AnchorSubsystem, XRVps2AnchorSubsystemDescriptor, Provider> | A tracking subsystem serving VPS2 anchors as trackables. |
| XRVps2AnchorSubsystemDescriptor | SubsystemDescriptorWithProvider<XRVps2AnchorSubsystem, Provider> | Descriptor for the XRVps2AnchorSubsystem. |
| XRVps2AssetSubsystem | TrackingSubsystem<XRVps2Asset, XRVps2AssetSubsystem, XRVps2AssetSubsystemDescriptor, Provider> | A tracking subsystem serving the origins of VPS assets as trackables. |
| XRVps2AssetSubsystemDescriptor | SubsystemDescriptorWithProvider<XRVps2AssetSubsystem, Provider> | Descriptor for the XRVps2AssetSubsystem. |
| XRVps2Subsystem | SubsystemWithProvider<XRVps2Subsystem, XRVps2SubsystemDescriptor, Provider> | The subsystem owning the VPS2 feature's lifecycle: configuration, localization, and geolocation. Anchors and asset origins are served by the XRVps2AnchorSubsystem and XRVps2AssetSubsystem trackable subsystems, which run against the feature this subsystem manages. |
| XRVps2SubsystemDescriptor | SubsystemDescriptorWithProvider<XRVps2Subsystem, Provider> | Descriptor for the XRVps2Subsystem. |
