Introduction
One of the most important objects in Three.js is the camera. With the camera, you
define what part of the scene will be rendered and how the information will be projec-
ted on the screen. In this chapter, we'll show you a number of recipes that will allow
you to add more complex camera functionality to your Three.js applications.
