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.

Rapier-supported shapes

Rapier provides a number of shapes you can use to wrap your geometries. In this section, we’ll walk you through all the available Rapier shapes and demonstrate these meshes through an example. Note that to use these shapes you need to call RAPIER.ColliderDesc.roundCuboid, RAPIER.ColliderDesc.ball, and so on.

Rapier provides 3D shapes and 2D shapes. We’ll only look at the 3D shapes provided by Rapier:

  • ball: A ball shape, configured by setting the radius of the ball
  • capsule: A capsule shape, defined by the half-height of the capsule and its radius
  • cuboid: A simple cube shape defined by passing in the half-width, half-height, and half-depth of the shape
  • heightfield: A height field is a shape for which each provided value defines the height of a 3D plane
  • cylinder: A cylinder shape defined by the half-height and the radius of the cylinder
  • cone: A cone shape defined by the half-height and the radius of the bottom of the...
