Professional WebGL is a detailed technical book that describes 3D graphics and the WebGL API. It includes several programming examples and will teach the reader what WebGL is and how it is used to build 3D web applications. WebGL is an API for advanced 3D graphics on the web. It is based on the 3D API OpenGL ES 2.0, and provides similar rendering functionality, but in a HTML and JavaScript context. This is the first book on the market that describes WebGL. The book starts with an introduction that gives readers a good overview of what WebGL is and how it relates to other graphics related standards. The reader will be taken through some important fundamental linear algebra that is essential to be able to have a deep understanding of 3D graphics with WebGL. The presentation of the linear algebra is not as abstract and general as most texts often provide. Instead, the focus is to make the topic easy to understand and only touch on the parts that are really relevant for 3D graphics with WebGL. The book continues with detailed hands-on examples of how to develop 3D graphics with WebGL. The reader will learn how to write vertex shaders and fragment shaders for WebGL. A complete chapter is dedicated to OpenGL ES 2.0 Shading Language, which is the programming language used to write shaders for WebGL. Important topics such as texturing and lightning are covered in detail. Since performance is often important for many 3D applications (including games), a chapter is devoted to invaluable information on WebGL performance optimization. The book includes many figures and detailed hands-on examples to ensure the reader comes away with a comprehensive understanding of WebGL development. The book is a "must have" for developers who really want to master WebGL.
