In this chapter, we covered a lot of information about the different kinds of lights that are available in Three.js. In this chapter, you learned that configuring lights, colors, and shadows is not an exact science. To get the correct result, you should experiment with the different settings and use a dat.GUI control to fine-tune your configuration. The different lights behave in different ways and, as we'll see in Chapter 4, Working with Three.js Materials, materials respond differently to lights as well. A THREE.AmbientLight color is added to each and every color in the scene and is often used to smooth hard colors and shadows. THREE.PointLight emits light in all directions and can cast shadows. THREE.SpotLight is a light that resembles a flashlight. It has a conical shape, can be configured to fade over distance, and is able to cast shadows. We also looked...

Overview of this book
WebGL makes it possible to create 3D graphics in the browser without having to use plugins such as Flash and Java. Programming WebGL, however, is difficult and complex. With Three.js, it is possible to create stunning 3D graphics in an intuitive manner using JavaScript, without having to learn WebGL. With this book, you’ll learn how to create and animate beautiful looking 3D scenes directly in your browser-utilizing the full potential of WebGL and modern browsers. It starts with the basic concepts and building blocks used in Three.js. From there on, it will expand on these subjects using extensive examples and code samples. You will learn to create, or load, from externally created models, realistic looking 3D objects using materials and textures. You’ll find out how to easily control the camera using the Three.js built-in in camera controls, which will enable you to fly or walk around the 3D scene you created. You will then use the HTML5 video and canvas elements as a material for your 3D objects and to animate your models. Finally, you will learn to use morph and skeleton-based animation, and even how to add physics, such as gravity and collision detection, to your scene. After reading this book, you’ll know everything that is required to create 3D animated graphics using Three.js.
