Spatial mapping in code

Add another script to the project and then to the camera. I have called it SurfaceHelper. The initial version looks as follows:

using System.Collections; 
using System.Collections.Generic; 
using UnityEngine; 
using UnityEngine.VR.WSA; 
 
public class SurfaceHelper : MonoBehaviour { 
 
    SurfaceObserver _observer; 
    void Start() 
    { 
        _observer = new SurfaceObserver(); 
        _observer.SetVolumeAsAxisAlignedBox(Vector3.zero, new Vector3(10f, 10f, 10f)); 
    } 
   private void HandleSurfaceChanged(  
         SurfaceId surfaceId,  
         SurfaceChange changeType,  
         Bounds bounds,  
         System.DateTime lastModification) 
   { 
         // This is where we handle all changes     
 
   } 
} 

In the Start() method, we initialize the whole thing. First, we create an instance of the SurfaceObserver class. ...
