WebA very basic example of combining vertex and fragment shaders. Instead of performing standard Gouraud shading (per-vertex lighting), the vertex shader performs all transformations, and the fragment shader performs the lighting per-pixel! Tested on Windows, should work on LINUX as well, let me know if you have trouble compiling it.
