We discussed a lot of items in this second introduction chapter. We showed all the functions and properties of THREE.Scene and explained how you can use these properties to configure your main scene. We also showed you how you can create geometries. You can either create them from scratch using a THREE.Geometry object or use any of the built-in geometries Three.js provides. Finally, we showed you how you can configure the two cameras Three.js provides. THREE.PerspectiveCamera renders a scene using a real-world perspective, and THREE.OrthographicCamera provides a fake 3D effect also often seen in games. We've also introduced how geometries work in Three.js. You can now easily create your own geometries.
In the next chapter, we'll look at the various light sources that are available in Three.js. You'll learn how the various light sources behave, how to create and configure them, and how they affect specific materials.
