Public Member Functions
IEnumerable< ObserverBehaviour >	GetObserverBehaviours ()
	Get all the ObserverBehaviours currently in the scene.
IEnumerable< T >	GetObserverBehaviours< T > ()
	Get all the ObserverBehaviours of type T currently in the scene.
IEnumerable< ObserverBehaviour >	GetTrackedObserverBehaviours ()
	Get all the ObserverBehaviours in the scene that are currently tracked.
IEnumerable< T >	GetTrackedObserverBehaviours< T > ()
	Get all the ObserverBehaviours of type T in the scene that are currently tracked.
bool	HitTest (Vector2 imageSpacePos, float defaultHeight, out HitTestResult hitTestResult)
	Perform a hit test in the world. The result is always of the first plane that is intersected with.

Properties
bool	AnchorsSupported [get]
	Returns true if anchors and hit test are supported.
IlluminationData	IlluminationData [get]
	Provides data on the estimated illumination values in the current frame such as illumination intensity or ambient light color temperature.

Events
Action< ObserverBehaviour >	OnObserverCreated
	Called whenever an observer is newly discovered by Vuforia. This can happen with VuMarks, CloudReco, Anchors or Barcodes.
Action< ObserverBehaviour >	OnObserverDestroyed
	Called whenever an observer tracked by Vuforia is lost. This can happen with VuMarks, CloudReco, Anchors or Barcodes.
Action	OnStateUpdated
	Updated whenever a new state of the world has been processed.

HitTest()

bool HitTest ( Vector2 imageSpacePos, float defaultHeight, out HitTestResult hitTestResult )

inline

Perform a hit test in the world. The result is always of the first plane that is intersected with.

Parameters

defaultHeight	The assumed height of the device whe performing the hit test is usually 1.4m
hitTestResult	Result of the hit test. If an intersection with a plane was detected, it's reflected here'

Returns

True if there is a hit test result
