> For those who don't understand the significance of this I highly encourage you to learn about ray tracing and the complexity of it. Ray tracing, at it's core, is actually beautifully simple. Also, ray tracing is absolutely not the interesting (or "significant") part of this article. I highly encourage to RTFA first. As for combining the two: having read on Raymond Chens blog about all the optimization that went into Notepad over the years, I'd guess Notepad is the real complex part here.
