Questions & Answers
1

I am using Vuforia’s Scanner app for scanning my object and OD file is added to unity, my problem is i want to gernerate a code which could tell me the postion of my 3 d object from diffrent camera position.
I am new to coding and unity so forgive me for asking too naive thing.

You can do that by typing this:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ExampleOne : MonoBehaviour
{
    public GameObject yourObject;

    void Update()
    {
        // Prints out position of your object every frame
        Debug.Log(yourObject.transform.position);
    }
}

Or, if you really want to have the position be displayed on a UI text object, here is code for normal Unity’s text:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class ExampleOne : MonoBehaviour
{
    public GameObject yourObject;

    public Text yourNormalText;

    void Update()
    {
        // Sets the text of yourNormalText UI element to be yourObject's position (float). DON'T FORGET UnityEngine.UI NAMESPACE!!!
        yourNormalText.text = yourObject.transform.position.ToString();

        // Sets the text of yourNormalText UI element to be yourObject's position (int).
        yourNormalText.text = yourObject.transform.position.ToString("0");
    }
}

Here is a bit better code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class ExampleOne : MonoBehaviour
{
    public GameObject yourObject;

    public Text yourNormalText;

    void Update()
    {
        // Float
        yourNormalText.text = "X: " + yourObject.transform.position.x.ToString() + "  Y: " + yourObject.transform.position.y.ToString() + "  Z: " + yourObject.transform.position.ToString();
        
        // Int
        yourNormalText.text = "X: " + yourObject.transform.position.x.ToString("0") + "  Y: " + yourObject.transform.position.y.ToString("0") + "  Z: " + yourObject.transform.position.z.ToString("0");
    }
}

Code for TextMeshPro:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;

public class ExampleOne : MonoBehaviour
{
    public GameObject yourObject;

    public TextMeshProUGUI yourTextMeshProText;

    void Update()
    {
        // Sets the text of yourNormalText UI element to be yourObject's position (float). DON'T FORGET TMPro NAMESPACE!!!
        yourTextMeshProText.text = yourObject.transform.position.ToString();

        // Sets the text of yourNormalText UI element to be yourObject's position (int).
        yourTextMeshProText.text = yourObject.transform.position.ToString("0");
    }
}

Bit better code for TextMeshPro:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;

public class ExampleOne : MonoBehaviour
{
    public GameObject yourObject;

    public TextMeshProUGUI yourTextMeshProText;

    void Update()
    {
        // Float
        yourTextMeshProText.text = "X: " + yourObject.transform.position.x.ToString() + "  Y: " + yourObject.transform.position.y.ToString() + "  Z: " + yourObject.transform.position.ToString();

        // Int
        yourTextMeshProText.text = "X: " + yourObject.transform.position.x.ToString("0") + "  Y: " + yourObject.transform.position.y.ToString("0") + "  Z: " + yourObject.transform.position.z.ToString("0");
    }
}

Hope you find this helpful!

Ok, it sounds like you want to get the position of your object in space relative to a camera object, at least that is what I understand from your question.

[SerializeField]  private Transform camTransform; //this is your other camera transform

[SerializeField] private Transform otherTransform; //this is your 3D object transform

private Vector3 posRelativeToCam;

private void Start()
{
     posRelativeToCam = otherTransform.position - camTransform.position;
   
     Debug.Log(“Position relative to Camera “ + posRelativeToCam);
}
