[Solved] How can I disable Point Cloud in AR Foundation ?

Hello,

I'm using the PlaneDectectionController.cs to enable/disable the planes but I'm looking for a way to hide the feature points too.

I have tried something like this :

Code (CSharp):

1. GameObject.FindWithTag("AROrigin").GetComponent<ARPointCloudManager>().enabled = false;

But it only freeze the feature point, not hide them.

I have also tried to find the point cloud's game object with GameObject.Find(), ) to disable or destroy it, but I guess I don't have the good name, I tried with those string : "Point Cloud", "Point cloud", "PointCloud", "Pointcloud".

Thank you in advance for your assistance.

 

Hi again,

I solved the problem myself. I guessed right the strings was wrong, so I print every childs' name of the gameobject "AR Session Origin" with this code :

Code (CSharp):

1.     public Text uiText;
2.     GameObject trackables;
3.  
4.     private void Update()
5.     {
6.         // Get a specific gameobject with its name
7.         trackables = GameObject.Find("Trackables");
8.         Debug.Log(trackables.name);
9.         // To find child in a specific gameobject
10.         foreach (Transform child in trackables.transform)
11.         {
12.             Debug.Log(child.name);
13.             this.uiText.text += child.name + "\n";
14.         }
15.     }

It's probably dirty but it was working, the name of my point cloud's gameobject was "AR Default Point Cloud(Clone)".
And after all, I destroyed it with Destroy("AR Default Point Cloud(Clone)").

 

Hi DonPeto,

The ARPointCloudManager only exposes the prefab, not the instance they create of the prefab ( the code doesn't keep a reference to the clone ).

Therefore currently the only way to find it is to do a search for it, like you've done.

You could also use code similar to below to get the name, in case the prefab is changed later on...

// Similar to what you did before, to get the ARPointCloudManager
ARPointCloudManager arCloudManager = arSessionOrigin.GetComponent<ARPointCloudManager>();
GameObject goPointCloud = arCloudManager.pointCloudPrefab;
// the prefab might not be set
if (goPointCloud != null)
{
GameObject goClone = GameObject.Find(goPointCloud.name + "(Clone)");
// check if the prefab instance has been created
if (goClone != null)
{
Destroy(goClone);
}
}

The ARPointCloudManager should really handle removing the particle system internally, hopefully it'll be fixed in the next update.

 

Hi, any updates?
I know that i can use

Code (CSharp):

1. ARSubsystemManager.depthSubsystem.Stop()

to stop displaying points and

Code (CSharp):

1. ARSubsystemManager.planeSubsystem.Stop()

for planes.
It works for planes, because ARPlane has an event
boundaryChanged whitch is called when plane disabled and i just react on this to fade the plane, but for the points there is nothing like this.

 

Oh, i know the better solution. Just need to disable pointCloud to disable all points:

Code (CSharp):

1. ARPointCloudManager _pointCloudManager;
2.  
3. //...
4.  
5. _pointCloudManager.pointCloud.gameObject.SetActive(false);

 

Still not working, Anyone with a working solution

Want to turn ON and OFF the point cloud.

 

Tested with 2019.1.7 ArFoundation 2.1

PointCloud.enabled = false; // stops from making new ones

foreach (var Point in PointCloud.trackables) // removes the existing ones.
{
Point.gameObject.SetActive(false);
}

 

Great! This work well!

 

Hey I need reference to 'ARPointCloudManager' (I modified the class a little bit). Your code does'nt work. 'goClone' is null. how to fix this?

 

Solution for ARFoundation version > 2.2.x

Code (CSharp):

1. var points =  SessionOrigin.GetComponent<ARPointCloudManager>().trackables;
2. foreach(var pts in points)
3. {
4.         pts.gameObject.SetActive(false);
5. }
6. SessionOrigin.GetComponent<ARPointCloudManager>().enabled = false;
7.  

 

ARPointCloudManager.SetTrackablesActive(false);
ARPlaneManager.SetTrackablesActive(false);

 

Hello guys .For disabling points. Just type before start()

public ARPointCloudManager cloudsPoints;

and then go there you want to disabling and type

cloudsPoints.SetTrackablesActive(false);

just like the @fancyar saying
