Class XRDepthSubsystem

An abstract class that provides a generic API for low-level depth detection features.

Inheritance
Object
XRSubsystem<XRDepthSubsystemDescriptor>
TrackingSubsystem<XRPointCloud, XRDepthSubsystemDescriptor>
XRDepthSubsystem
XRDepthSubsystemImpl
Inherited Members
Namespace: UnityEngine.XR.ARSubsystems
Syntax
public abstract class XRDepthSubsystem : TrackingSubsystem<XRPointCloud, XRDepthSubsystemDescriptor>
Remarks

This class can be used to access depth detection features in your app via accessing the generic API. It can also be extended to provide an implementation of a provider which provides the depth detection data to the higher level code.

Constructors

XRDepthSubsystem()

Constructs a depth subsystem. Do not invoked directly; call Create on the XRDepthSubsystemDescriptor instead.

Declaration
protected XRDepthSubsystem()

Methods

CreateProvider()

Implement this and return an instance of the XRDepthSubsystem.Provider.

Declaration
protected abstract XRDepthSubsystem.Provider CreateProvider()
Returns
Type Description
XRDepthSubsystem.Provider

An implementation of the XRDepthSubsystem.Provider.

GetChanges(Allocator)

Get the changes (added, updated, and removed) point clouds since the last call to GetChanges(Allocator).

Declaration
public override TrackableChanges<XRPointCloud> GetChanges(Allocator allocator)
Parameters
Type Name Description
Allocator allocator

An Allocator to use when allocating the returned NativeArrays.
Returns
Type Description
TrackableChanges<XRPointCloud>

TrackableChanges<T> describing the point clouds that have been added, updated, and removed since the last call to GetChanges(Allocator). The caller owns the memory allocated with Allocator.
Overrides
UnityEngine.XR.ARSubsystems.TrackingSubsystem<UnityEngine.XR.ARSubsystems.XRPointCloud, UnityEngine.XR.ARSubsystems.XRDepthSubsystemDescriptor>.GetChanges(Allocator)

GetPointCloudData(TrackableId, Allocator)

Declaration
public XRPointCloudData GetPointCloudData(TrackableId trackableId, Allocator allocator)
Parameters
Type Name Description
TrackableId trackableId
Allocator allocator
Returns
Type Description
XRPointCloudData

OnDestroyed()

Destroy the depth subsystem.

Declaration
protected override sealed void OnDestroyed()
Overrides
UnityEngine.XR.ARSubsystems.XRSubsystem<UnityEngine.XR.ARSubsystems.XRDepthSubsystemDescriptor>.OnDestroyed()

OnStart()

Start the depth subsystem, i.e., start collecting depth data.

Declaration
protected override sealed void OnStart()
Overrides
UnityEngine.XR.ARSubsystems.XRSubsystem<UnityEngine.XR.ARSubsystems.XRDepthSubsystemDescriptor>.OnStart()

OnStop()

Stop the subsystem, i.e., stop collecting depth data.

Declaration
protected override sealed void OnStop()
Overrides
UnityEngine.XR.ARSubsystems.XRSubsystem<UnityEngine.XR.ARSubsystems.XRDepthSubsystemDescriptor>.OnStop()
