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.

Exploring Advanced Geometries

In Chapter 5, Learning to Work with Geometries, we showed you all the basic geometries provided by Three.js. Besides these basic geometries, Three.js also offers a set of more advanced and specialized objects.

In this chapter, we’ll show you these advanced geometries:

  • How to use advanced geometries such as THREE.ConvexGeometry, THREE.LatheGeometry, THREE.BoxLineGeometry, THREE.RoundeBoxGeometry, THREE.TeapotGeometry, and THREE.TubeGeometry.
  • How to create 3D shapes from 2D shapes using THREE.ExtrudeGeometry. We’ll create a 3D shape from a 2D SVG image, and we will extrude from 2D Three.js shapes to create novel 3D shapes.
  • If you want to create custom shapes yourself, you can continue playing with the ones we’ve discussed in the previous chapters. Three.js, however, also offers a THREE.ParametricGeometry object. With parametric geometry, you can create geometry with parameters you can change to effect the shape of...
