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.

Working with the camera

Three.js has several camera controls you can use to control the camera throughout a scene. These controls are located in the Three.js distribution and can be found in the examples/js/controls directory. In this section, we’ll look at the following controls in more detail:

  • ArcballControls: An extensive control that provides a transparent overlay that you can use to easily move the camera around.
  • FirstPersonControls: These are controls that behave like those in first-person shooters. You can move around with the keyboard and look around with the mouse.
  • FlyControls: These are flight simulator-like controls. You can move and steer with the keyboard and the mouse.
  • OrbitControls: This simulates a satellite in orbit around a specific scene. This allows you to move around with the mouse and keyboard.
  • PointerLockControls: These are similar to the first-person controls but they also lock the mouse pointer to the screen, making it a great...
