Starting with a new scene

We start this project with a new empty scene and set it up with the AR Foundation objects: AR Session and AR Session Origin. Create a new scene named ARFramework using the following steps:

1. Create a new scene using File | New Scene.
2. Choose the Basic (Built-in) template. Press Create.
3. Save the scene using File | Save As, navigate to your Assets/Scenes/ folder, give it the name ARFramework, and then click Save.

Next, we'll set up the scene with the basic AR Foundation game objects as follows:

1. Delete Main Camera from the Hierarchy window by right-clicking and selecting Delete (or the pressing Del key on your keyboard).
2. Add an AR session by selecting GameObject from the main menu, and then XR | AR Session.
3. Add an AR Session Origin object by selecting GameObject from the main menu, and then XR | AR Session Origin.
4. Select the AR Session Origin object in the Hierarchy window. In the Inspector window, click Add Component...
