WebGL Lesson 13 - per-fragment lighting and multiple programs

This is a video of the results of my 13th WebGL lesson. WebGL is a system for hardware-accelerated 3D graphics in web pages, and this lesson shows how to implement per-fragment lighting (also called per-pixel lighting, or Phong shading), which gives more realistic results than the simpler per-vertex lighting technique, at the cost of using more graphics processor power.

You can read more about the code at http://learningwebgl.com/blog/?p=1523 --and the WebGL page itself is http://learningwebgl.com/lessons/lesson13/index.html if you have a WebGL-enabled browser; here's how to get one if you don't: http://learningwebgl.com/blog/?p=11
