I managed to successfully port some cg shaders over to glsl, gave them a spring-cleaning and integrated them into an OpenGL 3.2 core renderer (yeah, OS X 10.8 if you have to ask – bummer). It is kinda “the real deal”: thinfilm interference evaluated per lambda with interactive refraction indices, light + material spectral power distributions and thickness. I might have more results soon, so far these images below have to do:

Besides I still have other work todo, writing down my ph.d thesis…
