Ray Tracing To Replace Rasterization?
"Daniel Pohl has created new rendering engines for both Quake 3 and Quake 4 that use ray tracing as the draw method instead of the standard rasterization techniques used in all games today. Read on to find out more..."

Imagine playing a computer game in the quality seen in the movies of the "Lord of the Rings"-series; absolute realistic lighting, details like in real life, believable skins and much more.
One technique that was used creating the images for those movies is called "ray tracing". This is an alternative rendering technology compared to what actual graphic cards on modern PCs and consoles do. For many years ray tracing has only been used for offline-rendering and the generation of pictures for movies often took many days to calculate. Real-time ray tracing has been made possible with the OpenRT Ray tracing library. Through using many PCs over an Ethernet network interactive frame rates could be rendered in high resolution. Now, four years later CPUs have progressed a lot and ray tracing works in small resolutions on a single PC in real-time.
So what is OpenRT?
OpenRT is a ray tracing library developed by the Computer Graphics Group of Saarland University. The syntax of the API is nearly identical to OpenGL.
Interested in some light reading on OpenRT, then head here for an explanation on how it works.
