Eureka

After a bout with salmonella, I've regained my health and went back to work, debugging the normal mapping code I was working on previously and banging my head against a wall in frustration. It seemed like no matter what I did, I could not get per pixel lighting to work on all faces. After realizeing it was only the floor/ceiling i was having issues I tracked down the problem. Long story short, it was the old Garbage in = garbage out equation at work, and after realizing that I am quite happy with the results. I'm now at the point of integrating the various techniques I've worked on over the past few months into my current engine.

Now the question is... what next?
