Instant Trackers provide markerless 3D tracking of a scene, allowing to place augmentations anywhere in the real world. An Instant Tracker can be in two states: Initializing, during which the tracking origin can be set; and Tracking, during which the scene is being tracker. More...
Public Member Functions | |
| void | SetState (InstantTrackingState state) |
| Request that the tracker change to a new state. When the tracker actually changes to that state, the OnStateChange will be called. More... | |
| void | ConvertScreenCoordinate (Vector2 screenCoordinate) |
| Use this method to perform a hit test on the point cloud coming from the instant tracker. The computation is done on a separate thread and the result is passed to OnScreenConversionComputed. More... | |
| void | RequestPointCloud () |
| Use this method to request the current point cloud from the instant tracker. The computation is done on a separate thread and the result is passed to OnPointCloudRequestFinished. More... | |

Properties | |
| float | DeviceHeightAboveGround [get, set] |
| Allows changing the estimated height at which the device is currently above the ground in meters. Setting this to an appropriate value will allow the augmentations to have a scale close to the one they would have in reality. Can only be set if the tracker is in the Initializing state. More... | |
| InstantTrackingPlaneOrientation | TrackingPlaneOrientation [get, set] |
| Gets or sets the tracking plane orientation with which instant tracking initializes. If the plane orientation is set to custom, then the TrackingPlaneOrientationAngle will be used. Can only be set if the tracker is in the Initializing state. More... | |
| float | TrackingPlaneOrientationAngle [get, set] |
| Gets or sets the tracking plane orientation angle in degrees. Can only be set while the tracker is in Initializing state. It is only considered if the TrackingPlaneOrientation is set to Custom. Valid values are between -360 and 360 degrees. More... | |
Instant Trackers provide markerless 3D tracking of a scene, allowing to place augmentations anywhere in the real world. An Instant Tracker can be in two states: Initializing, during which the tracking origin can be set; and Tracking, during which the scene is being tracker.
When Instant Trackers are created at runtime, make sure that all the relevant properties are set before the OnEnable method is called by Unity. At OnEnable, the native tracker is created and all information needs to be available.

Allows changing the estimated height at which the device is currently above the ground in meters. Setting this to an appropriate value will allow the augmentations to have a scale close to the one they would have in reality. Can only be set if the tracker is in the Initializing state.

Gets or sets the tracking plane orientation with which instant tracking initializes. If the plane orientation is set to custom, then the TrackingPlaneOrientationAngle will be used. Can only be set if the tracker is in the Initializing state.
