Preface
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.
What this book covers
Chapter 1, Creating Your First 3D Scene with Three.js, covers the basic steps you need
to take to get started with Three.js. You'll immediately create your rst Three.js scene
and at the end of this chapter, you'll be able to create and animate your rst 3D scene
directly in your browser.
Chapter 2, Basic Components That Make Up a Three.js Scene, explains the basic
components that you need to understand when working with Three.js. You'll learn
about lights, meshes, geometries, materials, and cameras. In this chapter, you will
also get an overview of the different lights Three.js provides and the cameras you
can use in your scene.
