Learn Three.js - Fourth Edition

By: Jos Dirksen

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.

Working with Three.js Materials

In Chapter 3, Working with Light Sources in Three.js, we talked a bit about materials. You learned that a material, together with a THREE.Geometry instance, forms a THREE.Mesh object. A material is like the skin of an object that 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. The resulting THREE.Mesh object can then be added to the scene to be rendered by Three.js.

So far, we haven’t looked at materials in much detail. In this chapter, we’ll dive into all the materials Three.js has to offer, and you’ll learn how you can use these materials to create good-looking 3D objects. The materials we’ll explore in this chapter are shown in the following list:

  • MeshBasicMaterial: This is a basic material that you can use to give your geometries a simple color or show the wireframe of your geometries. This material isn...
