What I could put in this blog

Here I want to show some techs I think interesting about shader optimisation, 3d game engine developpement, graphics production pipeline for real time games.
At my work, we have developped some fun techs about global illumination, ambient occlusion & shadows, all fake of course ( it's always "fake" in 3d real time graphics) , but which should work great. Hope I can show soon some nice pics.
For now some great links I found :
