Overview of this book

Three.js has become the industry standard for creating stunning 3D WebGL content. In this edition, you’ll learn about all the features of Three.js and understand how to integrate it with the newest physics engines. You'll also develop a strong grip on creating and animating immersive 3D scenes directly in your browser, reaping the full potential of WebGL and modern browsers. The book starts with the basic concepts and building blocks used in Three.js and helps you explore these essential topics in detail through extensive examples and code samples. You'll learn how to create realistic-looking 3D objects using textures and materials and how to load existing models from an external source. Next, you'll understand how to control the camera using the Three.js built-in camera controls, which will enable you to fly or walk around the 3D scene you've created. Later chapters will cover the use of HTML5 video and canvas elements as materials for your 3D objects to animate your models. You’ll learn how to use morph targets and skeleton-based animation, before understanding how to add physics, such as gravity and collision detection, to your scene. Finally, you’ll master combining Blender with Three.js and creating VR and AR scenes. By the end of this book, you'll be well-equipped to create 3D-animated graphics using Three.js.

Loading and Working with Textures

In Chapter 4, Working with Three.js Materials, we introduced you to the various materials that are available in Three.js. However, we didn’t discuss applying textures to the material that’s used when creating a mesh. In this chapter, we’ll look at that subject. Specifically, we’ll discuss the following topics:

  • Loading textures in Three.js and applying them to a mesh
  • Using bump, normal, and displacement maps to apply depth and detail to a mesh
  • Creating fake shadows using a lightmap and an ambient occlusion map
  • Using specular, metalness, and roughness maps to set the shininess of specific parts of a mesh
  • Applying an alpha map for partial transparency of an object
  • Adding detailed reflections to a material using an environment map
  • Using the HTML5 Canvas and video element as input for a texture

Let’s start with a basic example, where we will show you how to load and apply a texture...
