You can view the source code here: light.js. Feel free to copy from it, but please notify me if you use it for something cool. :) Also beware that the code is pretty hacky and unpolished.
How it works
The 3D effect is basically created using 2 textures. One contains the color of each pixel and the other the surface normal. The color image is rendered using only indirect lighting (ambient occlusion in that case). The direct light is then calculated in real time using phong shading without the diffuse part. For a more accurate description, read the source. ;)
The dragon head used in this demo comes from planetpixelemporium.com. The Buddah is from the Stanford 3D Scanning Repository and was rendered and baked using blender. Thanks for letting me use it.comments powered by Disqus
