Learning Three.js: The JavaScript 3D Library for WebGL

By: Jos Dirksen

Overview of this book

<p>Three.js is a JavaScript 3D library that offers a wide range of features for creating and displaying stunning 3D computer graphics on a web browser in an intuitive manner using JavaScript without having to deal with the complexity of a WebGL low-level API. Even though WebGL makes it possible to create 3D graphics in the browser without having to use plugins, programming WebGL, however, is hard and complex. This book shows you how Three.js allows you to be independent of browser plugins.</p> <p>If you are an experienced web designer who wants to set the tone for an immersive design environment in your applications then this book is for you.<br /><br />"Learning Three.js: The JavaScript 3D Library for WebGL" is a practical, example-rich book that will help you to master all the features of Three.js. With this book, you’ll learn how to create and animate gorgeous looking 3D scenes directly in your browser utilizing the full potential of WebGL and modern browsers without having to learn WebGL.<br /><br />"Learning Three.js: The JavaScript 3D Library for WebGL" starts by going over 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. This will allow you to learn everything you need to know about Three.js in an easy and interactive manner.</p> <p>Besides the basic concepts, this book will show you how you can create realistic looking 3D objects using materials and textures as well as how to load them from externally created models. You’ll learn how to easily control the camera using the Three.js build-in camera controls so you can fly or walk around the 3D scene you have created. You will also learn how to use morph and bones-based animation and how to add physics to your scene.</p> <p>After reading Learning Three.js: The JavaScript 3D Library for WebGL and playing around with the extensive set of examples, you’ll know everything that is required to create 3D animating graphics using Three.js that run in any browser.</p>

Chapter 4. Working with the Three.js Materials

In the previous chapters we've already talked a bit about materials. You've learned that a material, together with a geometry, forms a mesh. The material is like the skin of the object, which defines what the outside of a geometry looks like. For example, a skin defines whether a geometry is metallic-looking, transparent, or shown as a wireframe. This mesh can then be added to the scene to be rendered by the Three.js library. So far we haven't really looked at the materials in much detail. In this chapter, we'll dive into all the materials that the Three.js library has to offer and you'll learn how you can use these materials to create good-looking 3D objects. The materials that we'll explore in this chapter are shown in the following table:
