How to stop plane detection using ARKit

Question

Hi guys.

As I understand, plane detection is tough battery consumer process. Once I've got my plane and set the base object for the game, I wish to stop plane detection (or generating reference points). Does anybody knows a how to disable plane detection? and a how to enable it again?

@tonymunoz One way to do that that is by re-running the UnityARSessionNativeInterface's RunWithConfig() with the new parameters, that belong's in UnityARCameraManager script. If you haven't altered the script the two function should do the work :

public void planeDetectionON() { planeDetection = UnityARPlaneDetection.Horizontal; ARKitWorldTrackingSessionConfiguration config = new ARKitWorldTrackingSessionConfiguration(); config.planeDetection = planeDetection; config.alignment = startAlignment; config.getPointCloudData = true; config.enableLightEstimation = true; m_session.RunWithConfig (config);

 }
 public void planeDetectionOFF()
 {
     planeDetection = UnityARPlaneDetection.None;
     ARKitWorldTrackingSessionConfiguration config = new ARKitWorldTrackingSessionConfiguration();
     config.planeDetection = planeDetection;
     config.alignment = startAlignment;
     config.getPointCloudData = false;
     config.enableLightEstimation = false;
     m_session.RunWithConfig (config);
 }

Hi.

This solution effectively stop the plane and anchors generation. Thank you very much. The problem now is that the ones that were available an instant before running planeDetectionOff() are still on. I wish to remove them too. I've been trying adding this code to planeDetectionOff, but it's not working:

         UnityARSessionRunOption options = new UnityARSessionRunOption();
         options = UnityARSessionRunOption.ARSessionRunOptionRemoveExistingAnchors | UnityARSessionRunOption.ARSessionRunOptionResetTracking;
         m_session.RunWithConfigAndOptions(config, options);

Lokking up the Arkit's Declearation the above code already exists RunWithConfig(). that is By Default the above code should run with those option but it's not running. Have no clue on how to stop it.
