Tracker Class

This property may differ from what was last requested with ConfigureAsync if one or more of the requested configuration options was not able to be satisfied. This represents the current state of the tracker.

It is possible for some configuration options to be satisfied while others are not, if, for example, one type of tracking is supported while another is not. In this case, ConfigureAsync will return something other than success (OVRResult<T>.Success) even though some options have been satisfied.Configuration represents the current state of the tracker at any given time; use this to determine the current configuration.

This method queries for anchors may be detected according to the current Configuration.Anchors may be returned in batches. If incrementalResultsCallback is not null, then this delegate is invoked whenever results become available prior to the completion of the entire operation. New anchors are appended to anchors . The delegate receives a reference to anchors and the starting index of the anchors that have been added. The parameters are:

• anchors: The same List provided by anchors .
• index: The starting index of the newly available anchors

This is similar to calling OVRAnchor.FetchTrackablesAsync(List<OVRAnchor>,IEnumerable<TrackableType>,Action<List<OVRAnchor>,int>) with an array of TrackableType. You can get the trackables associated with a TrackerConfiguration with TrackerConfiguration.GetTrackableTypes.

When you Dispose a Tracker, it stops tracking all trackables indicated by its Tracker.Configuration and destroys any internal resources associated with the tracker.
