We discussed many different postprocessing options in this chapter. As you saw, creating THREE.EffectComposer and chaining passes together is actually very easy. You just have to keep a few things in mind. Not all passes will have an output on the screen. If you want to output to the screen, you can always use THREE.ShaderPass with THREE.CopyShader. The sequence in which you add passes to a composer is important. The effects are applied in that sequence. If you want to reuse the result from a specific THREE.EffectComposer instance, you can do so by using THREE.TexturePass. When you have more than one THREE.RenderPass in your THREE.EffectComposer, make sure to set the clear property to false. If not, you'll only see the output from the last THREE.RenderPass step. If you want to only apply...

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.
