# XRScanningSubsystem

Source: https://www.nianticspatial.com/docs/api/unity/NianticSpatial.NSDK.AR.XRSubsystems.XRScanningSubsystem/

XRScanningSubsystem
> extends UnityEngine.SubsystemsImplementation.SubsystemWithProvider
Defines an interface for interacting with scanning functionality.

---

## Declaration

public class XRScanningSubsystem : SubsystemWithProvider<XRScanningSubsystem, XRScanningSubsystemDescriptor, Provider>

## Remarks

This abstract class should be implemented by an XR provider and instantiated using the SubsystemManager
to enumerate the available XRScanningSubsystemDescriptors.

---

## Constructors

public XRScanningSubsystem()

#### Summary

Constructor. Do not invoke directly; use the SubsystemManager
    to enumerate the available XRScanningSubsystemDescriptors
    and call Create on the desired descriptor.

## Properties

| Name | Type | Summary |
| --- | --- | --- |
| CurrentConfiguration | XRScanningConfiguration | Get or set configuration with |

---

## Methods

| Name | Type | Summary |
| --- | --- | --- |
| ComputeVoxels | void | Request a voxel buffer to be computed. This is an async operation that takes some time. Obtain the result with TryGetVoxels. "enableVoxels" must be set to true on the XRScanningConfiguration |
| DisposeVoxelBuffer | void | Dispose a voxel buffer previously obtained from TryGetVoxelBuffer |
| GetFrameCount | int | - |
| GetScanId | string | Get the current scan's ID. |
| GetState | ScanningState | Get the current state of the scanning subsystem. |
| GetVoxelSize | float | Get the current voxel size in meters. |
| SaveCurrentScan | void | Save the current scan. Recording will stop after save. ScanID will be reset. |
| TryGetRaycastBuffer | bool | Get the latest raycast textures. |
| TryGetVoxelBuffer | bool | Get latest computed voxel buffer. This then must be later disposed with DisposeVoxelBuffer |
