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.

The different kinds of lighting provided by Three.js

There are a number of different lights available in Three.js that all have specific behavior and usages. In this chapter, we'll discuss the following set of lights:




This is a basic light, the color of which is added to the current color of the objects in the scene.


This is a single point in space from which light spreads in all directions. This light can't be used to create shadows.


This light source has a cone-like effect like that of a desk lamp, a spot in the ceiling, or a torch. This light can cast shadows.


This is also called infinite light. The light rays from this light can be seen as parallel, like, for instance, the light from the sun. This light can also be used to...
