16. INSTALLATION

17. Download Vuforia for Unity SDK
• https://developer.vuforia.com/downloads/sdk

18. Download Samples
• https://developer.vuforia.com/downloads/samples

19. Installing Vuforia Unity Extension
• Create new Unity Project
• Import the Vuforia Unity Extension
• Double clicking the *.unitypackage file
• Eg vuforia-unity-5-0-6.unitypackage
• Manually install package
• Assets -> Import Package -> Custom Package
• The extension archive will self install
• folders, plugins and libraries, etc

20. Imported Vuforia Assets

21. Unity Asset Structure
• Editor - Contains the scripts required to
interact with Target data in the Unity editor
• Plugins - Contains Java and native binaries
that integrate the Vuforia AR SDK with the
Unity Android or Unity iOS application
• Vuforia - Contains the prefabs and scripts
required to bring AR to your application
• Streaming Assets / QCAR - Contains the
Device Database configuration XML and
DAT files from the online Target Manager

22. USING VUFORIA

23. Setting up a Vuforia Project
• Create a Project
• Replace Main Camera with AR camera
• Obtain a License Key
• Add license key to AR Camera
• Add Tracking Targets
• Add sample object

24. Register as Developer
• https://developer.vuforia.com/user/register

25. Create License Key
• https://developer.vuforia.com/targetmanager/licenseManager/licenseListing

26. Obtain a License Key
• Vuforia 5 apps utilize a license key that uniquely identifies
each app. License keys are created in the License Manager
• The steps to creating a new license key are..
• Choose a SDK
• Choose a licensing option based on your requirements
• Provide your Billing Information if you've chosen to use a paid license
• Obtain your license Key

27. License Key Generated

28. Add License Key to Vuforia Project
• Open ARCamera Inspector in Vuforia
• Assets -> Vuforia -> Prefabs
• Move AR Camera to scene hierarchy (Delete Main Camera)
• Paste License Key

29. Obtain a License Key
• Vuforia 5 apps utilize a license key that uniquely identifies
each app. License keys are created in the License Manager
• The steps to creating a new license key are..
• Choose a SDK
• Choose a licensing option based on your requirements
• Provide your Billing Information if you've chosen to use a paid license
• Obtain your license Key

30. Adding Tracking Targets
• Create a target on the Target Manager
• OR - Use existing targets from other projects

31. Which Type of Database
• Device Database vs. Cloud Database?
• Device: local, Cloud: online

32. Creating a Target
• Create a database
• Add targets

33. Selecting Target Type

34. Loaded Image Target
• Rating indicates how good a target
• Download Dataset -> create unity package

35. Building the AR Application
• Delete “Main Camera” in Scene Hierarchy
• Drag ARCamera prefab in the Scene Hierarchy
• Vuforia -. Prefabs -> AR Camera
• Import tracking dataset package
• Assets -> Import Package -> Custom Package
• Drag ImageTarget prefab into Scene Hierarchy
• Select ImageTarget, pick Data Set then Image Target
• On AR Camera load target database and activate

36. Running the Application

37. Add 3D Content
• As a test, create a simple Cube object
• GameObject > Create Other > Cube
• Add the cube as a child of the ImageTarget object by
dragging it onto the ImageTarget item.
• Move the cube until it is centered on the Image Target.

38. Cube Test

39. AR Test View

40. Sample Applications
• Object Recognition
• Image Targets
• Cylinder Targets
• Multi Targets
• User Defined Targets
• Smart Terrain (Unity only)
• Cloud Recognition
• Text Recognition
• Frame Markers
• Virtual Buttons

41. DEPLOYING TO MOBILE

42. APPLICATION
• Unity
• Creating the Application
• Configure the export settings and build the Application
42

43. Building for Android
• Open Build Settings
• Change Target platform to Android
• Switch Platform
• Under Player Settings
• Edit Bundle Identifier – eg com.UniSA.cubeTest
• Minimum API level
• Build and Run
• Select .apk file name
