public sealed class ARKitCameraSubsystem : XRCameraSubsystem, ISubsystem

Fields

backgroundShaderNames

The names for the background shaders based on the current render pipeline.

Declaration
public static readonly string[] backgroundShaderNames
Field Value
Type Description
string[]

The names for the background shaders based on the current render pipeline.
Remarks

There are two shaders in the Apple ARKit Provider Package. One is used for rendering before opaques and one is used for rendering after opaques.

In order:

  1. Before Opaques Shader Name
  2. After Opaques Shader Name

Properties

advancedCameraConfigurationSupported

Get whether advanced camera hardware configuration is supported. Advanced camera hardware configuration requires iOS 16 or newer and a device with an ultra-wide camera.

Declaration
public bool advancedCameraConfigurationSupported { get; }
Property Value
Type Description
bool

true if setting advance camera hardware configurations is supported. Otherwise, false.
See Also

backgroundShaderName

The name for the background shader.

Declaration
[Obsolete("'backgroundShaderName' is obsolete, use backgroundShaderNames instead. (2022/04/04)")]
public static string backgroundShaderName { get; }
Property Value
Type Description
string

The name for the background shader.

Methods

TryAcquireHighResolutionCpuImage()

Creates and returns a promise of a high resolution CPU image. You can yield return on the promise in a coroutine to await the asynchronous result.

Requires iOS 16 or newer.

Declaration
public HighResolutionCpuImagePromise TryAcquireHighResolutionCpuImage()
Returns
Type Description
HighResolutionCpuImagePromise

The promise instance.
Remarks

See ARKit's captureHighResolutionFrameWithCompletion documentation for more information.

On iOS 15 or below, promises will immediately resolve with an unsuccessful result.

Only one instance of HighResolutionCpuImagePromise at a time can await a result. Promises created while another promise is in progress will immediately resolve with an unsuccessful result.

Examples
IEnumerator MyCoroutine()
{
    var promise = TryAcquireHighResolutionCpuImage();
    yield return promise;
    if (promise.result.wasSuccessful)
        Debug.Log(promise.result.highResolutionCpuImage.ToString());
}

TryGetLockedCamera(out ARKitLockedCamera)

Locks the primary camera associated with the current session configuration and returns an object that represents it. Use this object to configure advanced camera hardware properties. For more information, see ARKit's [AVCaptureDevice.lockForConfiguration] (https://developer.apple.com/documentation/avfoundation/avcapturedevice/1387810-lockforconfiguration?language=objc).

Declaration
public bool TryGetLockedCamera(out ARKitLockedCamera lockedCamera)
Parameters
Type Name Description
ARKitLockedCamera lockedCamera

A disposable object that represents the locked configurable primary camera.
Returns
Type Description
bool

true if a configurable camera is available in the current session configuration and can be locked. Otherwise, false.
Remarks

Requires iOS 16 or newer and a device with an ultra-wide camera.
