AR-Foundation Proper way to turn off planes after basic placement

Hi I have probably a simple question but I wondering what the best way to do it.

I am currently working on a game where you place a object where you raycast to the plane. After the object is placed, I got a reference to the planes that were created. How should I turn them off so they aren't seen? Also if I do like simple renderer and collider component off, does it affect them meaning, do they stay in that state until the session is complete?

Here's what I have for now.



Thanks and sorry if this is simple lol

Check out the TogglePlanes example here

https://github.com/Unity-Technologies/arfoundation-samples/tree/master/Assets/Scenes/Plane Detection

Script here:

https://github.com/Unity-Technologi...er/Assets/Scripts/PlaneDetectionController.cs

.. should help you

 

Awesome, thanks very much!

 

Thanks for that link!

 

Does this disable only the visualizations? Or, does it completely stop plane detection of the session?

 

Same question

 

There's also a utility function for this available on all trackable managers.

 

It only disables the existing ARPlanes' GameObjects; new planes will continue to be detected. If you want to disable plane detection, disable the ARPlaneManager.

 

You say 'planes will continue to be detected' I'm confused dose the first line of code in this function() not disable enable the ARPlaneManager stopping plane detection ?

Code (CSharp):

1. public void TogglePlaneDetection()
2.     {
3.         m_ARPlaneManager.enabled = !m_ARPlaneManager.enabled;
4.  
5.         string planeDetectionMessage = "";
6.         if (m_ARPlaneManager.enabled)
7.         {
8.             planeDetectionMessage = "Disable Plane Detection and Hide Existing";
9.             SetAllPlanesActive(true);
10.         }
11.         else
12.         {
13.             planeDetectionMessage = "Enable Plane Detection and Show Existing";
14.             SetAllPlanesActive(false);
15.         }
16.  
17.         if (togglePlaneDetectionText != null)
18.             togglePlaneDetectionText.text = planeDetectionMessage;
19.     }

 

Correct, disabling the ARPlaneManager will disable plane detection. I meant that deactivating the existing ARPlanes will not stop plane detection, i.e., what SetTrackablesActive does.

 

When is it appropriate to turn off plane detection?

 

When you don't want to detect planes. For example, if you have already detected a plane and placed whatever content you need, you can disable the plane detection - assuming you don't need to place more content.

 

Good thing you guys mentioned turning off the detections. Once I placed in models, and detection was running, it would cause memory issues and crash. Turning off detection helped.

 

Hi!
I have just this problem, when i place my model (preloaded and not instantiated) cause lag and freeze for a moment...
I've tried everything, any suggestions? @tdmowrer
Thanks a lot!

EDIT: When i restart the Scene with an AsyncOperation, the model place without issue. I mean, only have this issue when its the first time of the "run"... I dont know why...

 

Thanks for the tip.

 

If I disable PlaneDetection and disable the existing Trackable's gameObjects, does that effect the stability of previously placed ReferencePoints?

 

It doesn't affect the tracking, it only removes the GameObjects, not the actual tracked planes, as I understand

 

unnanego: Are you sure? This is what tdmowrer wrote above:
Correct, disabling the ARPlaneManager will disable plane detection. And setting an entire GO to inactive should disable all its scripts, what's left?

 

As I understand, the tracking data is not stored in the GameObjects themselves, they are just a representation of the planes in the scene. My guess would be, the ARPlaneManager has the tracking data.

 

After giving it some thought, I think the solution is even more simple. The anchorpoints are only important if the environment changes, so your object gets repositioned to the point where foundation puts the plane after obtaining more information. Once you stop tracking, the Unity world does not change anymore and we should be fine either way.

 

I tried to use Enable/Disable planeTrackable to Toggle Plane Detection, it is okay for normal cases;
However, i have a case that the plane trackables' poses go wrong because of lost tracking (e.g close app or move fast);

So, I want to know the way to reset the detection and detect the plane from scratch again.

I tried to know the ways to do so but can't find any.
Could anyone tell me?

 

You need to save the world map where you close app and load the world map again on open.
Check the examples on saving world map and I'm sure there's an example on reseting the plane detection.

 

If you instantiate the model using the Addressables.InstantiateAsync, you'll see it run smoother.

 

Hello guys , i am using AR foundation sample toggle plane detection , and PlaceOnPlane.cs sample Cube , but after disable plane detection still i am getting hit pos on plane on touch !!
is there i am missing something ??

 

to disable plane detection you must disable the ARPlaneManager component

 

Simply Comment Else Condition
/*else
{
spawnedObject.transform.position = hitPose.position;
}*/

 

1) Disable ARPlane Manager Script
2) SetTrackableActive(false) Also OR
Deactivate Root Trackables is child of ARCamera. Find Trackables Gamobject and TrackablesGO.SetActive(false);

 

Here’s something interesting. I tried to turn off plane detection after loading a serial world map. It messed up the pose driver so the plane shifts out of position. So, I’m stuck leaving it running all the time.

 

Disable it after the worldmap is loaded, maybe?

 

Yes, I even disabled a few seconds after the worldmap loaded. I guess the world origin or the pose driver is dependent on the plane detection being on.

 

How exactly are you turning it off? SetTrackableActive(false) only kills the gameobjects, not the planes as trackables inside ARKit, but if you disable ARPlaneManager script, plane tracking will be disabled completely. Which of these two are you doing?

 

ARPlaneManager.enable = false;

I'll try to show you with a video when I can.

 

Check out this video

I load the WorldMap, and then I press the button to turn off ARplaneManager. The plane and Model shift right behind the device so you don't see it.

 

that's exactly what I'm talking about - you shouldn't disable ARPlaneManager, disabling it removes plane tracking completely, you should set the prefab of the plane visualisator to null and do SetTrackablesActive(false) on the ARPlaneManager.

 

This is how I did it, for both stopping the visibility of the planes and for the detection of planes. I called the TrackingToggle() and the PlaneToggle() methods from UI Toggle buttons in Unity.
I found that if I only turned off SetTrackablesActive but was still finding planes then new planes would still get drawn, that's why I also made the prefab inactive.

Code (CSharp):

1.  
2.     /// <summary>
3.     /// The not-documented enum mode to detect both horizontal and vertical planes
4.     /// </summary>
5.     private PlaneDetectionMode detectEverything = (PlaneDetectionMode)3;
6.  
7.  
8.     /// <summary>
9.     /// Toggle whether planes are actively being detected or not
10.     /// </summary>
11.     public void TrackingToggle()
12.     {
13.         detectPlanes = !detectPlanes;
14.         arPlaneManager.detectionMode = detectPlanes ? detectEverything : PlaneDetectionMode.None;
15.         Debug.Log("Detection mode is now " + arPlaneManager.detectionMode.ToString());
16.     }
17.  
18.     /// <summary>
19.     /// Toggle whether found planes are visible or not
20.     /// </summary>
21.     public void PlaneToggle()
22.     {
23.         planesAreVisible = !planesAreVisible;
24.         arPlaneManager.SetTrackablesActive(planesAreVisible);
25.         arPlaneManager.planePrefab.SetActive(planesAreVisible);
26.     }
27.  
28.  

 

Hi friend!! would you be so kind to share an example project with this solution of yours, thank you very much!

 

I will share an example project with a tutorial in 5-6 hours.

 

wooww !! the truth would be very useful, thank you very much, we will be waiting, thank you

 

did you share that tutorial? thank you!

 

arPlaneManager.detectionMode is now obsolete, is there an alternative now?

 

try requestedDetectionMode: https://docs.unity3d.com/Packages/c...ndation_ARPlaneManager_requestedDetectionMode

 

Confirmed it works, I also disable the actual Prefab that the plane manager spawns

 

I tried this method and adjusted some of the methods to the new API changes, but I guess Im missing something, because the visual still shows up.

First lets check if we talk about the same thing, I want to remove these small "circles" which show the plane ground, this thread is talking about the same thing, correct?

I have a button which allows you to pick a location so in this state I want the plane / circles to show and in the "play" state I want the circles to be hidden.

Can someone give me some things about a fully working solution to toggle these circles with the current AR APIs?

 

Hi,
could anyhone help me (who is not able to code ...) with this: mobile ios AR unity 2020.36f1
I want a scene with severeral objects to be instatiated automatically on a detectded plane ( the floor of the exhibition shall be "replaced" with another material slightly above the physical ground, other objects shall be placed in relational height to it).
- the ARDefaultPlane prefab is apperring always ca 40 cm too high.
- how can I stop the plane detection after the first plane was detected? (Without any toggle buttons )
i understand partly the code elements suggested but I don´t know where to change the initial code...
