WebGL Up and Running by Tony Parisi

ImageThis book provides good techniques for building pages that include 3D content by using WebGL  It’s not an in-depth study of  WebGL but a good guide to getting started. Using the examples provided, you learn to achieve compelling results quickly.

A brief introduction to 3D graphics and WebGL is followed by a survey of the features available from WebGL. The book focuses on using Three.js to create pages with 3D content. This is a great way to easily leverage WebGL but it does start to feel more like a manual for Three.js than a book about WebGL.

All the common topics encountered when providing 3D content on web page are presented. I liked the gradual process of presenting each topic;  getting things working and then elaborating and adding extras. I found all the topics extremely relevant to real projects. In particular coverage of interaction between normal web-page content and 3D content is well covered and useful.

In the latter case, create a virtual folder (in IIS, Apache Tomcat or the like), paste the pages and access them from there.

You will certainly be up-and-running but might still feel  the need to find out more about WebGL in particular.
