Overview of this book

As highly interactive applications have become an increasingly important part of the user experience, WebGL is a unique and cutting-edge technology that brings hardware-accelerated 3D graphics to the web. Packed with 80+ examples, this book guides readers through the landscape of real-time computer graphics using WebGL 2. Each chapter covers foundational concepts in 3D graphics programming with various implementations. Topics are always associated with exercises for a hands-on approach to learning. This book presents a clear roadmap to learning real-time 3D computer graphics with WebGL 2. Each chapter starts with a summary of the learning goals for the chapter, followed by a detailed description of each topic. The book offers example-rich, up-to-date introductions to a wide range of essential 3D computer graphics topics, including rendering, colors, textures, transformations, framebuffers, lights, surfaces, blending, geometry construction, advanced techniques, and more. With each chapter, you will "level up" your 3D graphics programming skills. This book will become your trustworthy companion in developing highly interactive 3D web applications with WebGL and JavaScript.

Advanced Geometry-Loading Techniques

So far, we’ve rendered very simple objects. Now, let's investigate how to load a geometry (vertices and indices) from a file instead of declaring the vertices and indices every time we call initBuffers. To do this, we will make asynchronous calls to the web server using AJAX. We will retrieve the file with our geometry from the web server and then use the built-in JSON parser to convert the context of our files into JavaScript objects. In our case, these objects will be the vertices and indices arrays.

Introduction to JavaScript Object Notation (JSON)

JSON stands for JavaScript Object Notation. It is a lightweight, text-based, open format used for data interchange. JSON is commonly...
