Class XRDepthSubsystem

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

Inheritance
Object
TrackingSubsystem<XRPointCloud, XRDepthSubsystemDescriptor>
XRDepthSubsystem
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

Destroy()

Destroy the depth subsystem.

Declaration
public sealed override void Destroy()

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)

GetInterface()

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

Declaration
protected abstract XRDepthSubsystem.IDepthApi GetInterface()
Returns
Type Description
XRDepthSubsystem.IDepthApi

An implementation of the XRDepthSubsystem.IDepthApi.

GetPointCloudData(TrackableId, Allocator)

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

Start()

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

Declaration
public override void Start()

Stop()

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

Declaration
public override void Stop()
