Summary

In this last chapter, we explored how you can extend the basic 3D functionality from Three.js by adding physics. For this, we used the Physijs library, which allows you to add gravity, collisions, constraints, and much more. We also showed how you can add positional sound to your scene using the THREE.Audio and THREE.AudioListener objects. With those subjects, we've reached the end of this book on Three.js. In these chapters, we covered a lot of different subjects and explored pretty much everything Three.js has to offer. In the first couple of chapters, we explained the core concepts and ideas behind Three.js; after that, we looked at the available lights and how materials affect how an object is rendered. After the basics, we explored the various geometries Three.js has to offer and how you can combine geometries to create new ones.

In the second part of the book, we looked at a few more advanced subjects. You learned how to create particle systems, how to load models from external...
