You may remember building a diorama project from a shoebox for school as a child. We're going to make one today, using Unity. Let's assemble our first scene, which is composed of simple geometric objects. Along the way, we'll talk about using Unity, world scale, and rendering. We'll also explore various sources for 3D content, where you can find them, and how to use them in your Unity VR scenes. In this chapter, we will get you started in creating VR projects with Unity and work through some core concepts, including the following:

Installing Unity
Getting started with Unity
Creating a simple diorama
Using prefabs
Creating and importing content
