Constructors

XREnvironmentProbeSubsystem()

Constructs an XREnvironmentProbeSubsystem. Do not create this directly. Call Create on an XREnvironmentProbeSubsystemDescriptor obtained from the SubsystemManager.

Declaration
public XREnvironmentProbeSubsystem()

Properties

automaticPlacementEnabled

True if the AR session will automatically place environment probes in the scene, false otherwise.

Declaration
public bool automaticPlacementEnabled { get; }
Property Value
Type Description
bool
See Also

automaticPlacementRequested

Specifies whether the AR session should automatically place environment probes in the scene.

Declaration
public bool automaticPlacementRequested { get; set; }
Property Value
Type Description
bool

true if automatic placement of environment probes is enabled. Otherwise, false.
Remarks

If both manual and automatic placement of environment probes are supported, manually placed environment probes can be specified via TryAddEnvironmentProbe(Pose, Vector3, Vector3, out XREnvironmentProbe) regardless of whether automatic placement is enabled or not.

Exceptions
Type Condition
NotSupportedException

Thrown when setting this value to true for implementations that do not support automatic placement.

environmentTextureHDREnabled

True if HDR environment textures are enabled.

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

environmentTextureHDRRequested

Specifies whether the environment textures should be returned as HDR textures.

Declaration
public bool environmentTextureHDRRequested { get; set; }
Property Value
Type Description
bool

true if the environment textures should be returned as HDR textures. Otherwise, false.

Methods

GetChanges(Allocator)

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

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

The Allocator to use when allocating the returned NativeArrays.
Returns
Type Description
TrackableChanges<XREnvironmentProbe>

TrackableChanges<T> describing the planes that have been added, updated, and removed since the last call to GetChanges(Allocator). The caller owns the memory allocated with Allocator and is responsible for disposing it.
Overrides

Register(XREnvironmentProbeSubsystemCinfo)

Registers a subsystem implementation based on the given subystem parameters.

Declaration
[Obsolete("XREnvironmentProbeSubsystem.Register(XREnvironmentProbeSubsystemCinfo) has been deprecated in AR Foundation version 6.0. Use XREnvironmentProbeSubsystemDescriptor.Register(XREnvironmentProbeSubsystemDescriptor.Cinfo) instead.")]
public static bool Register(XREnvironmentProbeSubsystemCinfo environmentProbeSubsystemCinfo)
Parameters
Type Name Description
XREnvironmentProbeSubsystemCinfo environmentProbeSubsystemCinfo

The parameters defining the environment probe functionality implemented by the subsystem provider.
Returns
Type Description
bool

true if the subsystem implementation is registered. Otherwise, false.
Exceptions
Type Condition
ArgumentException

Thrown when the values specified in the environmentProbeSubsystemCinfo parameter are invalid. Typically, this happens when required parameters are null or empty or types that do not derive from the required base class.

RemoveEnvironmentProbe(TrackableId)

Asynchronously removes the environment probe matching the trackable ID from the AR session.

Declaration
public bool RemoveEnvironmentProbe(TrackableId trackableId)
Parameters
Type Name Description
TrackableId trackableId

Trackable ID of the environment probe to be removed from the AR session.
Returns
Type Description
bool

true if the environment probe is found in the current AR session and will be removed. Otherwise, false.
Remarks

RemoveEnvironmentProbe can be used to remove both manually placed and automatically placed environment probes if the implementation supports such removals, as indicated by the descriptor properties supportsRemovalOfManual and supportsRemovalOfAutomatic.

Exceptions
Type Condition
NotSupportedException

Thrown for platforms that do not support removal of the type of environment probe.

TryAddEnvironmentProbe(Pose, Vector3, Vector3, out XREnvironmentProbe)

Tries to create an environment probe.

Declaration
public bool TryAddEnvironmentProbe(Pose pose, Vector3 scale, Vector3 size, out XREnvironmentProbe environmentProbe)
Parameters
Type Name Description
Pose pose

The position and rotation at which to create the environment probe.
Vector3 scale

The scale at which to create the environment probe.
Vector3 size

The size (dimensions) of the environment probe to create.
XREnvironmentProbe environmentProbe

If successful, populated with the newly created environment probe. Otherwise, it will contain default values.
Returns
Type Description
bool

true if the environment probe was successfully added, otherwise false.
Exceptions
Type Condition
InvalidOperationException

Thrown when the environment probe subsystem is not running and this method is called to an add environment probe.
NotSupportedException

Thrown for platforms that do not support manual placement of environment probes.
