• start()
  

  Starts tracking.

• stop()
  

  Stops tracking.

• count()
  

  Returns the current number of trackable planes in the scene.

• ARTrackable get(int i)
  

  Returns the i-th trackable plane.

• ARTrackable get(String id)
  

  Returns the trackable with the given id.

• ARTrackable get(int mx, int my)
  

  Returns the trackable that's being hit by the current touch pointer.

• clearAnchors(Collection anchors)
  

  Disposes the anchors in the list that are no longer being tracked and removes them from the list.

import processing.ar.*;

ARTracker tracker;
ARAnchor anchor;

void setup() {
  fullScreen(AR);
  tracker = new ARTracker(this);
  tracker.start();  
}

void draw() {
  for (int i = 0; i < tracker.count(); i++) {
    ARTrackable trackable = tracker.get(i);
    // ...
  }
}
