Face Recognition Augmented Reality in Unity3d using Metaio SDK

### 1) Get the Metaio SDK
Go install the METAIO SDK.
http://www.metaio.com/products/sdk/
### 2) Create a new project and include the SDK.
### 3) Add SDK assets
- Add a metaioSDK prefab and include your app key
- Set the tracking configuration to "FACE"
- Add a metaioTracker to the scene
### 4) Add a Tracker Camera Script
This script sits metaioTracker game object. It is the only custom script in the project.
````
using System;
using System.Collections;
using System.IO;
using System.Threading;
using UnityEngine;
public class TrackerCamera : MonoBehaviour
{
public Camera Cam;
private float next;
public float Delay = 5;
public AudioSource Snap;
void Awake()
{
enabled = false;
}
public void TrackerState(bool e)
{
enabled = e;
}
void Update()
{
if (next <= Time.timeSinceLevelLoad)
TakePicture();
}
public void TakePicture()
{
var file = string.Format("{0}.png", DateTime.UtcNow.Ticks);
var path = Path.Combine(Application.persistentDataPath, file);
Debug.Log(path);
#if UNITY_ANDROID
StartCoroutine(TakePictureAndroid(file));
#else
Application.CaptureScreenshot(path);
#endif
//feedback
if (Snap)
Snap.Play();
//update counter
next = Time.timeSinceLevelLoad + Delay;
// stop camera
enabled = false;
}
private IEnumerator TakePictureAndroid(string filePath)
{
//Wait for graphics to render
yield return new WaitForEndOfFrame();
//Create a texture to pass to encoding
var texture = new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);
//Put buffer into texture
texture.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
//Split the process
yield return new WaitForEndOfFrame();
// TODO Find a better way to save the images.
// ThreadPool hangs the app. Like hard.
// Maybe add textures to a list and save in batch.
// Use a plugin to save to the gallery on Android
AndroidPlugin.SaveImageToGallery(texture, filePath);
}
}
````
### 5) Add components to the tracker game object
- Include an audio source with your favorite snapshot sound
- Include a Quad facing the (game) camera to outline the faces.
