Overview of this book

Augmented Reality brings with it a set of challenges that are unseen and unheard of for traditional web and mobile developers. This book is your gateway to Augmented Reality development—not a theoretical showpiece for your bookshelf, but a handbook you will keep by your desk while coding and architecting your first AR app and for years to come. The book opens with an introduction to Augmented Reality, including markets, technologies, and development tools. You will begin by setting up your development machine for Android, iOS, and Windows development, learning the basics of using Unity and the Vuforia AR platform as well as the open source ARToolKit and Microsoft Mixed Reality Toolkit. You will also receive an introduction to Apple's ARKit and Google's ARCore! You will then focus on building AR applications, exploring a variety of recognition targeting methods. You will go through multiple complete projects illustrating key market sectors including business marketing, education, industrial training, and gaming. By the end of the book, you will have gained the necessary knowledge to make quality content appropriate for a range of AR devices, platforms, and intended uses.

So one approach is to save the DefaultPicture as a prefab and then instantiate new copies of it for each new image we add to the scene.

The plan is to add Add and Delete buttons to the toolbar. Clicking Add will create a new picture in the scene. Clicking Delete will remove the current picture from the scene.

Let's set that up now.

Add and Delete in the Toolbar

We'll first add the Add and Delete buttons to the toolbar:

  1. From the Project Assets/SimpleIcons/Prefabs folder, drag the DeleteButton prefab to the Hierarchy as a child of Toolbar.
  2. Set its Position X to 0.15.
  3. Add the PictureAction script component to the button.
  4. Set its Command to DELETE.
  5. From the Project Assets/SimpleIcons/Prefabs folder, drag...
