In the last couple of years, browsers have become more powerful and are capable platforms to deliver complex applications and graphics. Most of these, though, are standard 2D graphics. Most modern browsers have adopted WebGL, which allows you to not just create 2D applications and graphics in the browser, but also create beautiful and good performing 3D applications using the capabilities of the GPU.

Programming WebGL directly, however, is very complex. You need to know the inner details of WebGL and learn a complex shader language to get the most out of WebGL. Three.js provides a very easy to use JavaScript API around the features of WebGL, so you can create beautiful 3D graphics without having to learn WebGL in detail.

Three.js provides a large number of features and APIs that you can use to create 3D scenes directly in your browser. In this book, you'll learn all the different APIs Three.js has to offer through lots of interactive examples and code samples.
