Properties

currentConfiguration

The current camera configuration.

Declaration
public XRCameraConfiguration? currentConfiguration { get; set; }
Property Value
Type Description
Nullable<XRCameraConfiguration>

The current camera configuration, if it exists. Otherise, null.
Exceptions
Type Condition
NotSupportedException

Thrown when setting the current configuration if the implementation does not support camera configurations.
ArgumentNullException

Thrown when setting the current configuration if the given configuration is null.
ArgumentException

Thrown when setting the current configuration if the given configuration is not a supported camera configuration.
InvalidOperationException

Thrown when setting the current configuration if the implementation is unable to set the current camera configuration.

focusMode

The CameraFocusMode for the camera.

Declaration
public CameraFocusMode focusMode { get; set; }
Property Value
Type Description
CameraFocusMode

The focus mode for the camera.

lightEstimationMode

The LightEstimationMode for the camera.

Declaration
public LightEstimationMode lightEstimationMode { get; set; }
Property Value
Type Description
LightEstimationMode

The light estimation mode for the camera.

permissionGranted

Determines whether camera permission has been granted.

Declaration
public bool permissionGranted { get; }
Property Value
Type Description
Boolean

true if permission has been granted. Otherwise, false.

shaderName

The name of the shader used in background rendering.

Declaration
public string shaderName { get; }
Property Value
Type Description
String

The name of the shader used in background rendering.

Methods

GetConfigurations(Allocator)

Get the camera configurations currently supported for the implementation.

Declaration
public NativeArray<XRCameraConfiguration> GetConfigurations(Allocator allocator)
Parameters
Type Name Description
Allocator allocator

The allocation strategy to use for the returned data.
Returns
Type Description
NativeArray<XRCameraConfiguration>

The supported camera configurations.

OnBeforeStart()

Callback before the subsystem is started (but after it is created).

Declaration
protected override void OnBeforeStart()
Overrides
UnityEngine.XR.ARFoundation.SubsystemLifecycleManager<XRCameraSubsystem, XRCameraSubsystemDescriptor>.OnBeforeStart()

TryGetIntrinsics(out XRCameraIntrinsics)

Tries to get camera intrinsics. Camera intrinsics refers to properties of a physical camera which may be useful when performing additional computer vision processing on the camera image.

Declaration
public bool TryGetIntrinsics(out XRCameraIntrinsics cameraIntrinsics)
Parameters
Type Name Description
XRCameraIntrinsics cameraIntrinsics

The camera intrinsics to be populated if the camera supports intrinsics
Returns
Type Description
Boolean

true if cameraIntrinsics was populated. Otherwise, false.

TryGetLatestImage(out XRCameraImage)

Attempt to get the latest camera image. This provides directly access to the raw pixel data, as well as utilities to convert to RGB and Grayscale formats.

Declaration
public bool TryGetLatestImage(out XRCameraImage cameraImage)
Parameters
Type Name Description
XRCameraImage cameraImage

A valid XRCameraImage if this method returns true.
Returns
Type Description
Boolean

true if the image was acquired. Otherwise, false.
Remarks

The XRCameraImage must be disposed to avoid resource leaks.

Events

frameReceived

An event which fires each time a new camera frame is received.

Declaration
public event Action<ARCameraFrameEventArgs> frameReceived
Event Type
Type Description
Action<ARCameraFrameEventArgs>
