Last night I finally found a little time to look at GLSL shaders and how best to integrate some into Avogadro. I had been meaning to do this for quite some time but there is always so much to do and so little time! First problem I had was actually accessing the functions to use GLSL shaders. In the end I found a great little library called GLEW that lets me test for OpenGL 2.0 and then ensures all the functions are available.
