PlaneTracker
The
PlaneTracker
class provides functionality for locating a 3D plane based on 2D screen coordinates.Property | Description |
confidence | (get) confidence: StringSignal (set) (Not Available) Returns tracking confidence level info. This value indicates if PlaneTracker is currently tracking and how confident it is in reported results. Possible values: - HIGH - MEDIUM - LOW - NOT_TRACKING |
trackingMode | (get) trackingMode: SceneModule.TrackingMode (set) trackingMode: SceneModule.TrackingMode Specifies if this tracker object should track horizontal plane or moving object. |
Method | Description |
hitTest | hitTest(screenLocation: Point2D): Point3D Returns a point on tracked plane in local coordinates of PlaneTracker (in 3D units). Returns null if tracked plane is not found at given screen point. |
trackPoint | trackPoint(screenLocation: Point2D): void trackPoint(screenX: number, screenY: number): void trackPoint(screenLocation: PixelPointSignal, gestureState: StringSignal): void PlaneTracker origin is bound to a point in 3d space, located on detected plane. This method updates PlaneTracker to track 3d point currently under given screen coordiantes. This also triggers new plane detection, in result this object's transform will be modified. Version with signal parameters can be used in touch gestures for continuous updating: TouchGestures.onPan().subscribe(function(gesture) { planeTracker.trackPoint(gesture.location, gesture.state); }); |
