What we'll cover: * Three.js FirstPersonControls, how to use these in a project * Using Quaternions and Vector translations to create simple first person camera movement * Using sin waves and focus locking to improve the overall feeling and give it a more organic experience. Full source code for the project is available, so if you're interested in fiddling with the code, screwing around with it, or improving it.
