The document discusses using Vuforia with Unity to create augmented reality applications. It provides steps to set up a basic AR scene using Vuforia: 1) install the Vuforia package in Unity and add a development license key, 2) delete the main camera and add a new AR camera along with an image target, 3) drag 3D objects under the image target to place them in the scene. The document also covers deploying builds to Android and iOS, and lists additional resources for learning Unity, Vuforia, and AR development.

Making a Simple Scene
● GameObject Rotation
Example C# Script
using UnityEngine;
using System.Collections;
public class NewBehaviourScript: MonoBehaviour {
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
this.gameObject.transform.Rotate(Vector3.up*10);
}
}

23. Scripting C# Unity 3D
● void Awake():
○ Is called when the first scene is loaded and the gameobject is active
● void Start():
○ Called on first frame update
● void FixedUpdate():
○ Called before physics calculations are made
● void Update():
○ Called every frame before rendering
● void LateUpdate():
○ Once per frame after update finished
