Overview of this book

WebGL makes it possible to create 3D graphics in the browser without having to use plugins such as Flash and Java. Programming WebGL, however, is difficult and complex. With Three.js, it is possible to create stunning 3D graphics in an intuitive manner using JavaScript, without having to learn WebGL. With this book, you’ll learn how to create and animate beautiful looking 3D scenes directly in your browser-utilizing the full potential of WebGL and modern browsers. It starts with the basic concepts and building blocks used in Three.js. From there on, it will expand on these subjects using extensive examples and code samples. You will learn to create, or load, from externally created models, realistic looking 3D objects using materials and textures. You’ll find out how to easily control the camera using the Three.js built-in in camera controls, which will enable you to fly or walk around the 3D scene you created. You will then use the HTML5 video and canvas elements as a material for your 3D objects and to animate your models. Finally, you will learn to use morph and skeleton-based animation, and even how to add physics, such as gravity and collision detection, to your scene. After reading this book, you’ll know everything that is required to create 3D animated graphics using Three.js.

Render Postprocessing

We're approaching the end of the book, and, in this chapter, we'll look at one of the main features of Three.js that we haven't touched upon yet: render postprocessing.

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

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