How to count AR point cloud number? (AR Foundation 3.0.1)
Hi all. I have been trying to count the number of all ar point cloud collected in the AR session
I've tried the following code. But arPointCloud keeps throwing error message: Object reference not set to an instance of an object
I would be so happy if anyone can help me. :eek:
Thanks!
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.XR.ARFoundation;
public class PointNumberCount : MonoBehaviour
{
ARSessionOrigin arSessionOrigin;
ARPointCloud arPointCloud;
int totalNumber;
List<Vector3> featurePoints = new List<Vector3>();
void Start()
{
arSessionOrigin = GetComponent<ARSessionOrigin>();
arPointCloud = arSessionOrigin.trackablesParent.GetComponentInChildren<ARPointCloud>();
}
void Update()
{
arPointCloud = arSessionOrigin.trackablesParent.GetComponentInChildren<ARPointCloud>();
featurePoints = new List<Vector3>(arPointCloud.positions);
totalNumber = featurePoints.Count;
}
}
}
