Add X Rotation To This Orbit Script

Hi,

This orbit script is working well around one axis, but I'd like to add full 360º rotation.
Any suggestions?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. public class InputControl : MonoBehaviour
5. {
6.    public GameObject cameraOrbit;
7.  
8.    public float rotateSpeed = 8f;
9.  
10.    void Update()
11.    {
12.        if (Input.GetMouseButton(0))
13.        {
14.            float h = rotateSpeed * Input.GetAxis("Mouse X");
15.            float v = rotateSpeed * Input.GetAxis("Mouse Y");
16.  
17.            if (cameraOrbit.transform.eulerAngles.z + v <= 0.1f || cameraOrbit.transform.eulerAngles.z + v >= 179.9f)
18.                 v = 0;
19.  
20.            cameraOrbit.transform.eulerAngles = new Vector3(cameraOrbit.transform.eulerAngles.x, cameraOrbit.transform.eulerAngles.y + h, cameraOrbit.transform.eulerAngles.z + v);
21.        }
22.  
23.        float scrollFactor = Input.GetAxis("Mouse ScrollWheel");
24.  
25.        if (scrollFactor != 0)
26.        {
27.            cameraOrbit.transform.localScale = cameraOrbit.transform.localScale * (1f - scrollFactor);
28.        }
29.  
30.    }
31. }
