5 Things You Need to Know About Raytracing
Ray tracing is a widespread technique in computer graphics. You’ve probably seen stills and movies that involved ray tracing, whether in the graphics community or in movie theaters or on TV. The distinguishing feature of ray tracing is that it is one of the most photorealistic ways of rendering computer images. A trade off when using ray tracing is an increase in rendering time, so ray tracing is not used as often in real time situations.
Subsequently, the traditional way of rendering in some 3D programs and most games is not raytracing, but a process called “rasterization” that attempts to do the same thing, but much faster, though slightly less accurately. Ray tracing’s advantage over rasterization is that it’s capable of many more phenomena by default than rasterization, due to its property of being modeled on the real world. It’s this property, and the basic process of raytracing, that will be discussed in this article.

How Google Buzz is Gaining Many Early Followers
Since Google Buzz launched a few months ago, it has had some very impressive early adopters. Mashable and TechCrunch have been the first of many larger blogs to jump on board, with many smaller blogs following suit.
But just how has Google ramped up enough media coverage and PR to have such a successful launch? Clearly we can consider Buzz still in its beta stages, as there are many steps this feature can take in a new direction. I’ve got a few thoughts for Google as well, and I would love to see Buzz grow into a Twitter-like clone over the next few months.
