使用arcore unity计算两点之间的距离

using UnityEngine;
using UnityEngine.XR.ARFoundation;

public class DistanceCalculator : MonoBehaviour
{
    [SerializeField]
    private ARRaycastManager raycastManager;

    private Vector3 point1Position;
    private Vector3 point2Position;

    // Update is called once per frame
    void Update()
    {
        if (Input.touchCount == 2)
        {
            Touch touch1 = Input.GetTouch(0);
            Touch touch2 = Input.GetTouch(1);

            if (touch1.phase == TouchPhase.Began || touch2.phase == TouchPhase.Began)
            {
                // 射线投射以获取点的位置
                Ray ray1 = Camera.main.ScreenPointToRay(touch1.position);
                Ray ray2 = Camera.main.ScreenPointToRay(touch2.position);

                RaycastHit hit1, hit2;

                if (raycastManager.Raycast(ray1, out hit1) && raycastManager.Raycast(ray2, out hit2))
                {
                    point1Position = hit1.pose.position;
                    point2Position = hit2.pose.position;

                    // 计算两点之间的距离
                    float distance = Vector3.Distance(point1Position, point2Position);
                    Debug.Log("Distance between Point1 and Point2: " + distance + " meters");
                }
            }
        }
    }
}
