The syntax of the API is nearly identical to OpenGL. OpenRT is a ray tracing library developed by the Computer Graphics Group of Saarland University.

Now, four years later CPUs have progressed a lot and ray tracing works in small resolutions on a single PC in real-time, but more on this later. Through using many PCs over an Ethernet network interactive frame rates could be rendered in high resolution. Real-time ray tracing has been made possible with the OpenRT Ray tracing library. 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. This is an alternative rendering technology compared to what actual graphic cards on modern PCs and consoles do. One technique that was used creating the images for those movies is called ‘ray tracing’. (‘Lord of the Rings’-Movie: Rendered image with ray tracing – Copyright Newline Cinema)
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. Guest author Daniel Pohl shares with us his insight into using raytracing for game rendering and how the increasing power of multi-core processors are helping bring it to a reality.
