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.

Materials you can use for a line geometry

The last couple of materials we’re going to look at can only be used on one specific mesh: THREE.Line. As the name implies, this is just a single line that only consists of lines and doesn’t contain any faces. Three.js provides two different materials you can use on a THREE.Line geometry, as follows:

  • THREE.LineBasicMaterial: This basic material for a line allows you to set the color and vertexColors properties.
  • THREE.LineDashedMaterial: This has the same properties as THREE.LineBasicMaterial but allows you to create a dashed line effect by specifying dash and spacing sizes.

We’ll start with the basic variant; after that, we’ll look at the dashed variant.


The materials that are available for the THREE.Line geometry are very simple. It inherits all of the properties from THREE.Material, but the following are the properties that are most important for this material:
