  16. 16. Virtual Reality
  17. 17. Hand gestures to operate VR • Enhance e-Learning • Experience interactions = remember more • Test in class-room situations Use of iPhone’s touch screenImmersive e-book
  18. 18. Introduction to Unity
  19. 19. Unity as cross-platform game engine
  20. 20. Unity setup • Download from https://unity3d.com/get-unity/download
  21. 21. Create new project • Specify project name • Specify project location • Specify whether project is 3D or 2D • Specify asset packages (pre-made content)
  22. 22. User Interface Project Window Hierarchy Window Inspector Window Toolbar Scene View
  23. 23. Creating scenes • GameObjects • Every object in your scene is a GameObject • They are containers (for instance 3D object, texture, animation) • Object properties can be viewed and edited in Inspector • Position of GameObjects, cameras, lights can be seen and adjusted in Scene view • Interactions are added using Scripts attached to objects
  24. 24. Asset Workflow • Asset from outside of Unity: a 3D model, an audio file, an image, or any of the other types of file that Unity supports. • Asset created within Unity: an Animator Controller, an Audio Mixer, a Render Texture. • For instance to add 3D model: • Add file to Assets folder in Project • Drag mesh from Project View into Hierarchy or Scene View
  25. 25. GameObjects • GameObject contain Components, for instance Transform, Camera, etc. (seen from the Inspector)
  26. 26. Positioning GameObjects
  27. 27. New Project
  28. 28. Change layout (Windows  Layouts  Tall)
  29. 29. Moving main camera • Select Main Camera, select Translate Icon, Move camera
  30. 30. Creating immersive 360-degree viewer • Create new project • Add the Cardboard plugin VR SDK https://developers.google.com/vr/unity/ • Add 360-degree image asset • Create a Skybox • Add to the Scene • Publish on the Android device https://developer.android.com
  31. 31. Google Cardboard – see next slides • Open Unity and create new 3D project • Import the Unity package: Assets  Import Packages  Custom Package. • Select the GoogleVRForUnity package where you downloaded it and click on Open. • Check all the boxes and click Import. • You can test whether it works by opening Assets  GoogleVR  DemoScenes  HeadsetDemo  DemoScene. • Press Play (you should see a red cube). • Press the Control key on your keyboard and move your mouse around to tilt the view. Pressing Alt will cause too pan around the view of the VR.
  32. 32. Import Google VR • Import the Unity package: Assets  Import Packages  Custom Package. • Select the GoogleVRForUnity package where downloaded, and click on Open. • Check all the boxes (uncheck iOS) and click Import.
  33. 33. Demo (Assets  Google VR  DemoScenes  HeadsetDemo) • Press Play (should see a red cube, or green when navigated to it) • Press the Control key and move mouse to tilt your view (inside SceneView) • Press the Alt key and move mouse to pan around (inside SceneView)
  34. 34. Adding Cardboard to Empty Project • Drag GvrViewerMain from Assets  GoogleVR  Prefab to Hierarchy • Click on Play, should render stereo VR view (navigate using mouse and Control or Alt keys)
  35. 35. Import panoramic image (Disneyland, why not?)
  36. 36. Import panoramic image (Disneyland, why not?) • Create folder Textures in Assets • Drag and drop 360-disney.jpg to Assets  Textures • Click on the imported image: Inspector will show you properties of the texture
  37. 37. Change texture type • Change Texture Type from Texture to Cubemap • Change Mapping o Latitude-Longitude Layout (Cylindrical) • Click on Apply
  38. 38. Create Skybox material • Create folder Materials in Assets, and click right mouse button in that folder and Create  Material • Name material Sky01 and click in inspector on Select • In Select Cubemap choose 360-disney earlier created
  39. 39. Create Skybox • In Main Menu click on Window  Lightening • Drag Sky01 material into Skybox field • Background of SceneView should now display panoramic image in proper projection
  40. 40. Install on Android Change Bundle Identifier to something like au.com.qut.helloworld
  41. 41. Pushing to device
  42. 42. Thank you Now try it yourself :-D
