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.

Understanding common material properties

You can quickly see for yourself which properties are shared between all the materials. Three.js provides a material base class, THREE.Material, that lists all the common properties. We've divided these common material properties into the following three categories:

  • Basic properties: These are the properties you'll use most often. With these properties, you can, for instance, control the opacity of the object, whether it is visible, and how it is referenced (by ID or custom name).
  • Blending properties: Every object has a set of blending properties. These properties define how the color of each point of the material is combined with the color behind it.
  • Advanced properties: There are a number of advanced properties that control how the low-level WebGL context renders objects. In most cases, you won't need to deal with these...
