The interface is very similar to the Goraud example's interface. Please notice how the Phong shading combined with Phong lighting delivers a more realistic scene.
Click on the button Code. This will bring up the code viewer area. Check the vertex shader and the fragment shader with the respective buttons that will appear under the code viewer area. As in previous examples, the code has been commented extensively so you can understand every step of the process.
Now click on the button Controls to go back to the original layout. Modify the different parameters of the Phong lighting model to see the immediate result on the scene to the right.

Overview of this book
WebGL is a new web technology that brings hardware-accelerated 3D graphics to the browser without installing additional software. As WebGL is based on OpenGL and brings in a new concept of 3D graphics programming to web development, it may seem unfamiliar to even experienced Web developers.Packed with many examples, this book shows how WebGL can be easy to learn despite its unfriendly appearance. Each chapter addresses one of the important aspects of 3D graphics programming and presents different alternatives for its implementation. The topics are always associated with exercises that will allow the reader to put the concepts to the test in an immediate manner.WebGL Beginner's Guide presents a clear road map to learning WebGL. 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 WebGL topics, including drawing, color, texture, transformations, framebuffers, light, surfaces, geometry, and more. With each chapter, you will "level up"ù your 3D graphics programming skills. This book will become your trustworthy companion filled with the information required to develop cool-looking 3D web applications with WebGL and JavaScript.
