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.

Learning to Work with Geometries

In the previous chapters, you learned a lot about how to work with Three.js. Now you know how to create a basic scene, add lighting, and configure the material for your meshes. In Chapter 2, The Basic Components That Make Up a Three.js Scene, we touched upon (but didn’t really go into) the details of the available geometries that Three.js provides and that you can use to create your 3D objects. In this chapter and Chapter 6, Exploring Advanced Geometries, we’ll walk you through all the geometries that Three.js provides out of the box (except THREE.Line, which we discussed in Chapter 4, Working with Three.js Materials).

In this chapter, we’ll look at the following geometries:

  • THREE.CircleGeometry
  • THREE.RingGeometry
  • THREE.PlaneGeometry
  • THREE.ShapeGeometry
  • THREE.BoxGeometry
  • THREE.SphereGeometry
  • THREE.CylinderGeometry
  • THREE.ConeGeometry
  • THREE.TorusGeometry
  • THREE.TorusKnotGeometry
  • THREE...
