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.

Render Postprocessing

In this chapter, we’ll look at one of the main features of Three.js that we haven’t touched upon yet: render postprocessing. With render postprocessing, you can add additional effects to your scene after it is rendered. For instance, you could add an effect that makes the scene look like it is shown on an old TV, or you could add blur and bloom effects.

The main points we’ll discuss in this chapter are as follows:

  • Setting up Three.js for postprocessing
  • Some basic postprocessing passes provided by Three.js, such as BloomPass and FilmPass
  • Applying effects to part of a scene using masks
  • Using ShaderPass to add even more basic postprocessing effects, such as sepia filters, mirror effects, and color adjustments
  • Using ShaderPass for various blurring effects and more advanced filters
  • Creating a custom postprocessing effect by writing a simple shader
