Learn Three.js - Fourth Edition

By: Jos Dirksen

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.

Creating animations using external models

In Chapter 8, Creating and Loading Advanced Meshes and Geometries, we looked at several 3D formats that are supported by Three.js. A couple of those formats also support animations. In this chapter, we’ll look at the following examples:

  • COLLADA model: The COLLADA format has support for animations. For this example, we’ll load an animation from a COLLADA file and render it with Three.js.
  • MD2 model: The MD2 model is a simple format used in the older Quake engines. Even though the format is a bit dated, it is still a very good format for storing character animations.
  • glTF models: GL transmission format (glTF) is a format specifically designed for storing 3D scenes and models. It focuses on minimizing the size of the assets and tries to be as efficient as possible in unpacking the models.
  • FBX model: FBX is a format produced by the Mixamo tooling available at With Mixamo, you can easily rig...
