Making the augmented graphics

We provided the prefab annotation graphics to you (in the ChangeATire-ARGraphics.unitypackage). We should take a quick look at how they were created.

The general idea was to provide graphics that somewhat mimic the annotations used in the video graphics for the original How To Change A Tire article on the wikiHow site (http://www.wikihow.com/Change-a-Tire).

One approach is to create a new scene in our Unity project that will be used to compose the graphics:

1. From the main menu, select File | New Scene.
2. Then File | Save Scene As; name it Composition.
3. In Hierarchy, Create Empty, and name it Compose.
4. Ensure its Transform is reset.

We will create a canvas with the circle on it, like the one we used in the actual scene. But this one will be in World Space, and will have to be scaled for world space coordinates.

1. With Compose selected, create UI | Canvas.
2. Set its Render Mode to World Space.
3. As we did in Chapter 6, How to Change a Flat Tire, set its Width and Height to 480, 800...
