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.

Time for Action: Loading a Cone with AJAX

Follow the given steps:

  1. Make sure that your web server is running and access the ch02_07_ajax-cone.html file using your web server.
Web Server Address

You know that you are using the web server if the URL in the address bar starts with localhost/ or 127.0.0.1/ instead of file://.
  1. The folder containing the code for this chapter should look like this:
  1. Click on ch02_07_ajax-cone.html.
  2. The example will load in your browser and you will see something similar to this:
  1. Please review the load functions to better understand the use of AJAX and JSON in the application.
  2. How is the global model variable used? (Check the source code.)
  3. Check what happens when you change the color in the common/models/geometries/cone.json file and reload the page.
  4. Modify the coordinates of the cone in the common/models/geometries/cone.json file and reload the...
