Wow, I didn't post for the entire month of February. Not like it matters, apparently there's not be a single visitor for the past two weeks. Such is the life of a recluse.
In any case, I've been spending my evenings writing a ray tracer. It's an extraordinarily nerdy way to spend one's time, but I have been having a lot of fun, learning a lot of stuff and generally making some good progress.
So, since that has occupied my entire thought process for the past month, there hasn't been much other thinking going on. I could write about the intricacies of the integration of the rendering equation, which is pretty cool, and how photon mapping works, which is also cool, but that will have to wait until I find the time.
