Complete Virtual Reality and Augmented Reality Development with Unity

By: Jesse Glover, Jonathan Linowes

Overview of this book

Unity is the leading platform to develop mixed reality experiences because it provides a great pipeline for working with 3D assets. Using a practical and project-based approach, this Learning Path educates you about the specifics of AR and VR development using Unity 2018 and Unity 3D. You’ll learn to integrate, animate, and overlay 3D objects on your camera feed, before moving on to implement sensor-based AR applications. You’ll explore various concepts by creating an AR application using Vuforia for both macOS and Windows for Android and iOS devices. Next, you’ll learn how to develop VR applications that can be experienced with devices, such as Oculus and Vive. You’ll also explore various tools for VR development: gaze-based versus hand controller input, world space UI canvases, locomotion and teleportation, timeline animation, and multiplayer networking. You’ll learn the Unity 3D game engine via the interactive Unity Editor and C# programming. By the end of this Learning Path, you’ll be fully equipped to develop rich, interactive mixed reality experiences using Unity. This Learning Path includes content from the following Packt products: • Unity Virtual Reality Projects - Second Edition by Jonathan Linowes • Unity 2018 Augmented Reality Projects by Jesse Glover

Setting up the scene

To begin our exploration of input mechanisms, let's set up our scene. The plan is to let players create balloons. Everyone loves balloons!

For this scene, you could start with a new scene (File | New Scene) and then add the MyMyselfEye prefab we built in the previous chapter. Instead, I've decided to start with the Diorama scene created in the previous chapter, and remove all but the GroundPlane and PhotoPlane, as follows:

  1. Open the Diorama scene
  2. Remove all the objects, except for MyMyselfEye, Directional Light, GroundPlane and PhotoPlane
  3. Position the MeMyselfEye at the scene origin, Position (0, 0, 0)
  4. Select File | Save Scene As and give it a name, such as "Balloons"

Creating a balloon

For the balloon, you can simply use a standard Unity sphere 3D primitive if you choose. Or you can find an object in the Unity Asset Store or elsewhere. We are using a low poly balloon object that we found on Google Poly (https://poly.google.com/view/a01Rp51l-L3) and which is provided with the...
