Overview of this book

Three.js has become the industry standard for creating stunning 3D WebGL content. In this edition, you’ll learn about all the features of Three.js and understand how to integrate it with the newest physics engines. You'll also develop a strong grip on creating and animating immersive 3D scenes directly in your browser, reaping the full potential of WebGL and modern browsers. The book starts with the basic concepts and building blocks used in Three.js and helps you explore these essential topics in detail through extensive examples and code samples. You'll learn how to create realistic-looking 3D objects using textures and materials and how to load existing models from an external source. Next, you'll understand how to control the camera using the Three.js built-in camera controls, which will enable you to fly or walk around the 3D scene you've created. Later chapters will cover the use of HTML5 video and canvas elements as materials for your 3D objects to animate your models. You’ll learn how to use morph targets and skeleton-based animation, before understanding how to add physics, such as gravity and collision detection, to your scene. Finally, you’ll master combining Blender with Three.js and creating VR and AR scenes. By the end of this book, you'll be well-equipped to create 3D-animated graphics using Three.js.

Adding sound sources to your scene

Having discussed several relevant topics by now, we have a lot of the ingredients in place to create beautiful scenes, games, and other 3D visualizations. What we haven’t shown, however, is how to add sounds to your Three.js scene. In this section, we’ll look at two Three.js objects that allow you to add sources of sound to your scene. This is especially interesting since these sound sources respond to the position of the camera:

  • The distance between the sound source and the camera determines the volume of the sound source
  • The positions of the left-hand side and the right-hand side of the camera determine the sound volume of the left-hand side speaker and the right-hand side speaker, respectively

The best way to explain this is to see this in action. Open up the audio.html example in your browser, and you’ll see a scene from Chapter 9, Animations and Moving the Camera:
