Plane type detection about arfoundation-samples

[tdmowrer]

Support for specifying horizontal vs vertical was added in 1.0.0-preview.21.

Plane detection is either off or on. When on, it's both vertical and horizontal. We don't currently expose a way to only do horizontal detection. An enabled ARPlaneManager turns plane detection on. Disabling it turns it off.

Just for a little help, I believe you can check via code through

plane.boundedPlane.Alignment == UnityEngine.Experimental.XR.PlaneAlignment.Horizontal

Hi , Just a question ,

Can't we dynamically change the detection from vertical to horizontal and vice versa through code in ARFoundation ? I mean why only to be able to set in the property panel.

Plus, currently I'm building app which is doing vertical and horizontal detection , able to augment objects on detected planes BUT tracking both horizontal and vertical is causing issues , like the objects move away from their original location.

This doesn't seem to be typical normal behavior. any help??

Sure. The ARPlaneManager API lets you do this.

Plus, currently I'm building app which is doing vertical and horizontal detection , able to augment objects on detected planes BUT tracking both horizontal and vertical is causing issues , like the objects move away from their original location.

I need more information to diagnose a problem like that. Please log a bug with a project that reproduces the problem.

Thanks for the reply.

Can a sample code or atleast bear minimum few code lines would really help. At the moment I'm not sure how to use this planedetection mode in my code.

Suppose I want to change it to any mode type , how will I use this property.

Really and seriously appreciate your help in this.

Here's an example for how you might change the plane detection mode at runtime from a MonoBehaviour:

public ARPlaneManager planeManager;
void OnGUI()
{
    if (GUILayout.Button("Enable Horizontal"))
    {
        planeManager.detectionMode |= PlaneDetectionMode.Horizontal;
    }

    if (GUILayout.Button("Enable Vertical"))
    {
        planeManager.detectionMode |= PlaneDetectionMode.Vertical;
    }

    if (GUILayout.Button($"{(planeManager.enabled ? "Disable" : "Enable")} plane detection"))
    {
        // toggle plane detection
        planeManager.enabled = !planeManager.enabled;
    }
}
