Overview of this book

This book is ideal for anyone who already knows JavaScript and would like to get a broad understanding of Three.js quickly, or for those of you who have a basic grasp of using Three.js but want to really make an impact with your 3D visualizations by learning its advanced features. To apply the recipes in this book you don’t need to know anything about WebGL; all you need is some general knowledge about JavaScript and HTML.
