Constructors

BaseSpatialObserver(IMixedRealityServiceRegistrar, IMixedRealitySpatialAwarenessSystem, String, UInt32, BaseMixedRealityProfile)

Constructor.

Declaration
[Obsolete("This constructor is obsolete (registrar parameter is no longer required) and will be removed in a future version of the Microsoft Mixed Reality Toolkit.")]
protected BaseSpatialObserver(IMixedRealityServiceRegistrar registrar, IMixedRealitySpatialAwarenessSystem spatialAwarenessSystem, string name = null, uint priority = 10U, BaseMixedRealityProfile profile = null)
Parameters
Type Name Description
IMixedRealityServiceRegistrar registrar

The IMixedRealityServiceRegistrar instance that loaded the observer.
IMixedRealitySpatialAwarenessSystem spatialAwarenessSystem

The IMixedRealitySpatialAwarenessSystem to which the observer is providing data.
String name

The friendly name of the data provider.
UInt32 priority

The registration priority of the data provider.
BaseMixedRealityProfile profile

The configuration profile for the data provider.

BaseSpatialObserver(IMixedRealitySpatialAwarenessSystem, String, UInt32, BaseMixedRealityProfile)

Constructor.

Declaration
protected BaseSpatialObserver(IMixedRealitySpatialAwarenessSystem spatialAwarenessSystem, string name = null, uint priority = 10U, BaseMixedRealityProfile profile = null)
Parameters
Type Name Description
IMixedRealitySpatialAwarenessSystem spatialAwarenessSystem

The IMixedRealitySpatialAwarenessSystem to which the observer is providing data.
String name

The friendly name of the data provider.
UInt32 priority

The registration priority of the data provider.
BaseMixedRealityProfile profile

The configuration profile for the data provider.

Fields

DefaultSpatialAwarenessLayer

Default dedicated layer for spatial awareness layer used by most components in MRTK

Declaration
public const int DefaultSpatialAwarenessLayer = 31
Field Value
Type Description
Int32

Properties

DefaultPhysicsLayer

Get or sets the default Unity Physics Layer on which to set the spatial object.

Declaration
public int DefaultPhysicsLayer { get; }
Property Value
Type Description
Int32

IsRunning

Is the observer running (actively accumulating spatial data)?

Declaration
public bool IsRunning { get; protected set; }
Property Value
Type Description
Boolean

IsStationaryObserver

Should the observer remain stationary in the scene?

Declaration
public bool IsStationaryObserver { get; set; }
Property Value
Type Description
Boolean
Remarks

Set IsStationaryObserver to false to move the volume with the user. If set to true, the origin will be 0,0,0 or the last known location.

ObservationExtents

Gets or sets the extents( 1/2 size) of the volume, in meters per axis, from which individual observations will be made.

Declaration
public Vector3 ObservationExtents { get; set; }
Property Value
Type Description
Vector3
Remarks

When used when ObserverVolumeType is set to Sphere. The X value of the extents will be used as the radius.

ObserverOrigin

Declaration
public Vector3 ObserverOrigin { get; set; }
Property Value
Type Description
Vector3

ObserverRotation

Gets or sets the orientation of the volume in World Space.

Declaration
public Quaternion ObserverRotation { get; set; }
Property Value
Type Description
Quaternion
Remarks

This is only used when ObserverVolumeType is set to UserAlignedCube

ObserverVolumeType

Gets or sets the type of volume the observer should operate in.

Declaration
public VolumeType ObserverVolumeType { get; set; }
Property Value
Type Description
VolumeType

SourceId

The unique source id of this event source.

Declaration
public uint SourceId { get; }
Property Value
Type Description
UInt32

SourceName

The name of this event source.

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

SpatialAwarenessSystem

The spatial awareness system that is associated with this observer.

Declaration
protected IMixedRealitySpatialAwarenessSystem SpatialAwarenessSystem { get; }
Property Value
Type Description
IMixedRealitySpatialAwarenessSystem

StartupBehavior

Indicates the developer's intended startup behavior.

Declaration
public AutoStartBehavior StartupBehavior { get; set; }
Property Value
Type Description
AutoStartBehavior

UpdateInterval

Gets or sets the frequency, in seconds, at which the spatial observer should update.

Declaration
public float UpdateInterval { get; set; }
Property Value
Type Description
Single

Methods

CleanupObserver()

Ensures that the spatial observer has been stopped and destroyed.

Declaration
protected virtual void CleanupObserver()

ClearObservations()

Clears the observer's collection of observations.

Declaration
public virtual void ClearObservations()
Remarks

If the observer is currently running, calling ClearObservations will suspend it.

CreateObserver()

Creates the spatial observer and handles the desired startup behavior.

Declaration
protected virtual void CreateObserver()

Destroy()
