Virtual and Augmented Reality has been getting a lot of attention lately. Lots of really cool Head Mounted Devices (HMDs) like Oculus, Hololens, HTC Vive, FOVE, and Magic Leap have been coming up. The simplest and cheapest of all these HMDs is Google Cardboard, and it already has more than a million users worldwide.
Patrick has covered Building Google Cardboard VR Apps in Unity in his recent post. In the following two tutorials, we will be developing a basic Android Augmented Reality application for Google Cardboard using Unity3D. We will be using the Augmented Reality SDK named “Vuforia” to make this app.
The following software and the corresponding versions will be used in the following two posts:
- Vuforia 5
- Unity 3D 5.x
- Cardboard SDK version 0.5.x (needed for next tutorial)
- Android Studio and SDK tools (these need to be installed and set up for Unity builds to work. More information about this can be found in the “Integrating with Unity” section.)
Brief Overview
There are several approaches to making Augmented Reality apps. We will be using a marker based approach for making our AR app for mobile devices. In the next tutorial, we will be adding cardboard support.
Marker/Image Target – this is an image which is recognized and tracked by a mobile device’s camera. This acts as an origin for augmentation. Once recognized, content can be displayed with respect to it.
This tutorial will broadly have three parts:
- Getting started with Vuforia
- Integrating with Unity
- Demo (Fun part)
Getting started with Vuforia
To get started, we will need to go to Vuforia’s Developer Portal and create an account.
Once logged in, we can proceed to the “Develop” page. To use Vuforia with Unity, we will need to do two things:
- Create a license key for our applicationA license key is a unique ID which is required to create an app in Unity which uses Vuforia. To create a license key, we need to head over to “Develop >> License Manager” and select “Add License Key”. We will be prompted with a page like this one:Once we fill in the details, we can select “Next” and then “Confirm”. This will direct us back to the “License Manager” page where the application’s name will appear.Once we select “ARDemo”, we will get the license key. This key will be used later in Unity.
- Create a Database and an Image TargetThe next step is to set up an image as a target. We head over to “Develop >> Target Manager” and select “Add Database” and fill in the details:Next, we will need to add images to the newly made database. So, we select the database and click on “Add Target”. Vuforia supports various kinds of targets like single image, cylindrical, cuboidal, 3D image etc. For this tutorial, we will be using a single image target and the stones_hires image. Any arbitrary value can be selected for width, say 50.After a short upload time, the target will be added and we will have a “Download Dataset” option.An important thing to note here is the “Rating”. A good rating means that it can be used for tracking, whereas a bad rating means that the image does not have enough feature points (interesting points in the image like edges, corners etc which are used for tracking in image processing).We can also have a look at the feature points of our image by selecting “stones_hires >> Show features”
Let’s download the dataset by selecting “Download Dataset >> Unity editor”. Download converter pdf to word for mac.
This will generate a Unity package containing trackable information about this trackable database.
Integrating with Unity
Unity is a powerful and widely used game engine. Recently, it has also been emerging as the game engine for HMDs. The tutorial assumes very basic knowledge of Unity. You can find some more interesting tutorials on Unity here.
Let’s start by creating a new Unity3D project by the name of “ARDemo”.
Next, we will have to import the Vuforia Unity packages. This can be done by going to “Assets >> Import Package >> Custom Package”. We will have two packages, one corresponding to our dataset (
Image_Targets.unitypackage
) and the other corresponding to Vuforia 5 SDK for Unity (vuforia-unity-5-0-5.unitypackage
) which can be found here.Time to add some 3D models to our project. Let’s proceed to “Window >> Asset Store”. Here we can find a Samurai model by the name of “Red Samurai”, for free. We will have to log in with our Unity Account to download and import this model.
Once imported, our Assets folder will look like this:
Next, we will have to add an ARCamera to our scene. “ARCamera” is an Augmented Reality camera prefab from Vuforia and is very similar to a regular camera. We can find this under “Assets >> Vuforia >> Prefabs” and drag it into our scene at X=0, Y=0, Z=0. Let’s also delete the Main Camera from the scene (it can be found under the Hierarchy Panel, “Right Click >> Delete”) as we already have an ARCamera.
For our ARCamera to run, we will have to add the App License Key. In the Inspector panel, we will have to paste the unique key we had previously received from Vuforia’s License Manager.
At this point in time if we press the Play button in the Unity Editor we should be able to see our WebCam feed in the Game View.
Next, let’s add the ImageTarget to our scene. It can be found under “Assets >> Vuforia >> Prefabs”. Let’s add it to our scene at X=0, Y=-50, Z=0. Now, in the Inspector panel for the Image Target we will have to make some changes. Under the “Image Target Behaviour (script)” we will have to change “Data Set” to “Image_Targets” and “Image Target” to “stones_hires”. https://entrancementinfinite.weebly.com/the-crown-season-1-free-download-torrent.html. Once done, the
stone_hires
image will appear in our Scene View.Next, let’s drag our Samurai onto the Scene. It can be found under “Assets >> prefab >> samuzai”. For the samurai to appear over ImageTarget, it needs to be made a child of ImageTarget (can be done by just dragging the samuzai prefab in the Hierarchy panel). Then, whenever the ImageTarget is detected by a mobile device’s camera, all the children of the target will also appear together. The scale of the samuzai needs to be changed to X=0.5, Y=0.5, Z=0.5.
Now we need to activate the Image_Targets Dataset. This can be done by selecting “ARCamera”, and in the Inspector panel, under “Dataset Load Behaviour (Script)”, we need to select “Load Data Set Image_Targets” and then “Activate”.
At this point, if we select “Run” and point a print out of the image towards our webcam, we should see the samurai on it and doing “Attack animation” which is its default animation.
We are almost done. Let’s save the scene with the name “ARDemo”.
The last step is to build the project for Android. We need to go to “File >> Build Settings”. We need to add the current scene by selecting “Add Current”. Then, we need to select a platform (Android). Here, we will have multiple options:
- Google Android Project: This will allow us to export the current Unity project to Android Studio so it can be edited and used to add more elements.
- Development Build: Enabling this will enable Profiler functionality and also make the Autoconnect Profiler and Script Debugging options available.
We will be making a simple build as follows:
Before pressing the Build button, we need to make some more changes in the “Player Settings” options in the Inspector panel. Here, the company’s name needs to be changed; e.g. to “SitePoint”. Next, we need to change the Bundle Identifier under “Other Settings” say, to “com.SitePoint.ARDemo”.
Now, we can proceed to “Build and Run”. Other changes like Minimum API Level etc. can be made as per additional requirements. We will need to connect an Android mobile device via USB and enable USB debugging.
We will also need to have an Android developer environment set up before we can test our Unity games on the device. This involves downloading and installing the Android SDK with the different Android platforms, and adding our physical device to our system (this is done a bit differently depending on whether we are developing on Windows or Mac).
Since, this is a complex process, a basic outline of the tasks that must be completed before we can run code on our Android device or in the Android emulator has been provided in the Unity docs. However, a more detailed guide can be found in the first part of Patrick’s tutorial on VR.
The Final Result (Demo)
Augmented Reality Application Developm…
Finally, the fun and magical part!
Once the app builds and runs on Android we can point the mobile device’s camera to the marker and watch the animation. This is how the animation looks in my Nexus 5.
The AR app will work even with a black and white image of the stones because the feature points will still remain (they usually depend on other factors like gradient, etc. instead of color).
Conclusion
Lots of really cool stuff can be done with Unity and Vuforia. In this tutorial, we have made a simple AR app with animation without writing a script! In the followup tutorial, we will be adding cardboard support and some more interesting Vuforia features to our app.
If you get stuck at any point or want to view the source code, you can find it on Github. You will just have to enter your Vuforia App License Key to build the app.

Set up your development environment
- Install Android Studioversion 3.1 or higher with Android SDK Platform version 7.0 (API level 24)or higher.
- You will need a basic understanding of Android development. If you are newto Android, seeBuilding your first Android app for beginners.
Open the sample project
This quickstart uses Sceneform, a 3D framework for that makes iteasy for Java developers to build ARCore apps without OpenGL. To use ARCore inyour app without Sceneform, review the Enable ARCoredocumentation.
To continue with Sceneform, get the sample projects. You can either:
- Download and extract the Sceneform Samples-or-
- Clone the repository with the following command:
In Android Studio, open the Hello Sceneform sample project, located in the app subdirectory within the
sceneform-android-sdk
directory.Prepare your device or emulator
You can run AR apps on a supported device orin the Android Emulator:
- In the emulator, you must sign into the Google Play Store orupdate Google Play Services for AR manually.
There are additional requirements to runSceneform apps in the emulator:
Augmented Reality Application Development
- You need Android Emulator version 27.2.9 or later.
- OpenGL ES 3.0 or higher must be supported and enabled in the AndroidEmulator. Free download cute baby images for mobile wallpaper.
- Make sure your emulator is configured to use the latest version. In theExtended controls panel(on the Toolbar), select Settings > Advanced > OpenGL ES API level >Renderer maximum (up to OpenGL ES 3.1), and then restart the emulator.
- Run the emulator, briefly interact with the emulated deivce, then checkwhether OpenGL ES 3.0 or higher is being used:If you see
ver 3 0
or higher version, then you can run Sceneform apps.If you see a lower version, then your desktop GPU does not supportOpenGL ES 3.0 and you must use asupported device to run Sceneformapps.
Run the sample
Make sure your Android device is connected to the development machine and clickRun in Android Studio. Then, choose your deviceas the deployment target and click OK.
Android Studio builds your project into a debuggable APK, installs the APK, andthen runs the app on your device. For more information, see Build and Run Your App.
